Drug Interactions

The drugs are listed alphabetically in this chart. More complicated questions follow the chart, and they are in order of the most recent at the top.

CAUTION: Make sure all your health care providers have a complete list of your medications, including over-the-counter medications, herbals and vitamins.

More questions and answers are below this chart.

Can I take: with:
Acai Berry Lexapro (Escitalopram) Acai berry is not FDA-regulated, so there are few studies that have tested this with pharmaceuticals. The information I find does not list any direct interactions between acai and Lexapro. An issue with herbal products not conforming to FDA guidelines is the chance of having additional ingredients in the products that are not what you expect or want. Talk with your doctor before taking any herbal product. Your doctor may have patients who have experience to share.
Acetaminophen or Ibuprofen Cipro (Ciprofloxacin) Yes. Limit daily acetaminophen (Tylenol) to 3000mg or less. Take ibuprofen (Motrin, Advil) with food or milk to avoid stomach upset. Take Cipro until finished.
Adderall (Mixed Amphetamine Salts) Allegra (Fexofenadine) Yes. They may be taken together if needed.
Adderall (Mixed Amphetamine Salts) Antibiotics Yes. Take Adderall as prescribed at the same times daily and the antibiotic until finished.
Adderall (Mixed Amphetamine Salts)
Chlorpheniramine Maleate and Dextromethorphan HBr There is one possible interaction. If you take Adderall  for narcolepsy, the combination with a sedating antihistamine like chlorpheniramine (Chlor-Trimeton) may reverse the action of the amphetamines. Dextromethorphan (DM, Delsym) combined with chlorpheniramine can increase the chance of drowsiness.
Adderall (Mixed Amphetamine Salts) Cyanocobalamin Injection (Vitamin B12) Yes. Normally Adderall is used daily, and cyanocobalamin is given every week or month.
Adderall (Mixed Amphetamine Salts) DayQuil Cold and Flu There can be a problem taking Adderall with virtually any cold/allergy medication. Vicks DayQuil does not use antihistamines (diphenhydramine or doxylamine), but does have decongestants (pseudoephedrine or phenylephrine). Taking pseudoephedrine with amphetamine products can increase the risk of high blood pressure, nervousness, palpitations, problems with sleep, or other serious side effects. Discuss your drug regimen with your health care provider before taking these drugs together. If it's allowable, do not drive or operate machinery until you know how these drugs affect you. Use Tylenol (acetaminophen) or Motrin (ibuprofen) for flu aches and fever. For nasal congestion, use Ocean Nasal Spray (saline). It's effective and does not cause interactions.
Adderall (Mixed Amphetamine Salts) Dextromethorphan (DM/ Delsym) and Phenylephrine Yes. Phenylephrine and Adderall can cause increase in heart rate and jittery feelings. If you have heart problems or high blood pressure, talk to your doctor before taking phenylephrine.
Adderall (Mixed Amphetamine Salts) Effexor (Venlafaxine) There can be a drug interaction between Effexor (venlafaxine) and Adderall (mixed amphetamine salts). Are these prescribed by the same doctor? If not, please speak to your doctors before taking these at the same time.
Adderall (Mixed Amphetamine Salts) Lasix (Furosemide) Yes. Take each at the same time daily, normally in the morning. If you take Lasix regularly, notify your physician if you develop cramps. This could be a sign of potassium depletion.
Adderall (Mixed Amphetamine Salts) Lodrane (brompheniramine with pseudoephedrine) Do not take Adderall (mixed amphetamines) and Lodrane (brompheniramine with pseudoephedrine) together without talking to your physician. Taking pseudoephedrine with the amphetamine products can increase the risk of high blood pressure, nervousness, palpitations, problems with sleep or other serious side effects.
Adderall (Mixed Amphetamine Salts) Methimazole (Tapazole) Yes.
Adderall (Mixed Amphetamine Salts) Neurontin (Gabapentin) and Lunesta (Eszopiclone) Adderall and Lunesta are fine. There is a big problem with Adderall and Neurontin, particularly if you take Neurontin for seizures. These drugs are not commonly prescribed together. Do not take anticonvulsants, like Neurontin (drugs used to treat seizures or epilepsy) and amphetamine products together without talking to your health care provider. Amphetamines may decrease the effectiveness of anticonvulsants (when used for treating seizures) by lowering the threshold for seizures. Do not drive or operate machinery until you know how these drugs affect you. Report confusion, dizziness, excessive drowsiness, falls, unsteadiness or difficulty walking, unusual eye movements or other troublesome side effects promptly. If you are taking the Neurontin for another indication, I would still double-check with your physician.
Adderall (Mixed Amphetamine Salts) Percocet (Oxycodone with Acetaminophen) Yes. Take the Adderall as prescribed and the Percocet only as needed.
Adderall (Mixed Amphetamine Salts) Phenergan (Promethazine)   Yes. Take Adderall in the morning. Take Phenergan at bedtime> It may cause drowsiness. Take Phenergan only as needed.
Adderall (Mixed Amphetamine Salts) Adipex (Phentermine) Generally, multiple stimulant drugs (sympathomimetics) are not prescribed together. Please speak to your physician before taking both of these in the same day.
Adderall (Mixed Amphetamine Salts) Prednisone and Fexofenadine (Allegra) Yes. Take prednisone with food or milk to prevent stomach upset. The only problem would be if you need to take the prednisone for a long time and blood tests are taken to determine cortisol (steroid) levels. Adderall may interfere with these types of tests.
Adderall (Mixed Amphetamine Salts) Prozac (Fluoxetine) and Roxicodone (Oxycodone) Taking Prozac and Roxicodone together may make you drowsy. Do not drive or operate machinery until you know how these drugs affect you. If you notice slurred speech, confusion, severe weakness or difficulty breathing, contact your doctor immediately. Prozac could reduce the effectiveness of Roxicodone, so if you are taking products containing hydrocodone, let your prescriber know if your pain or coughing is not relieved. Taking Adderall and Prozac together could result in side effects such as confusion, dizziness, drowsiness, excessive dry mouth, nausea/vomiting, loss of coordination, muscle weakness, sweating, tremor and palpitations. Report these or other unusual side effects immediately.
Adderall (Mixed Amphetamine Salts) Pseudoephedrine I would not take Adderall with any cold medication that has a decongestant. Pseudoephedrine (Sudafed) constricts blood vessels. Taking this with Adderall, or any stimulant drug, can increase the risk of high blood pressure, nervousness, palpitations, sleep problems or other serious side effects. Talk to your physician.
Adderall (Mixed Amphetamine Salts) Relora I can find no medical references indicating any testing or reporting of interactions between Adderall and Relora. Please discuss your use of herbals with your physician.
Adderall (Mixed Amphetamine Salts) Tapazole (Methimazole) Yes. Take both exactly as prescribed.
Adderall XR Clarinex (Desloratadine) Yes. Drink plenty of fluids (not alcohol) with the Clarinex.
Adderall XR Flexeril (Cyclobenzaprine) Yes. Take Adderall as directed at the same times each day. Take cyclobenzaprine as needed. It can cause drowsiness.
Adderall XR Hydrochlorothiazide (Hydrochlorot) Yes. Take both early in the day. Plan ahead for the Adderall prescriptions, as these require a new prescription each time.
Adderall XR Protonix (Pantoprazole), Keflex (Cephalexin) and Multiple Vitamins
Yes. But Protonix can affect absorption of some types of minerals and vitamins. So, if you take Protonix once daily, take the vitamins 6-8 hours before or after. If you take Protonix twice daily, take the vitamins halfway between. Take the Keflex until it is finished.
Adderall XR and Fluoxetine (Prozac) Dextromethorphan (DM, Delsym) Fluoxetine can interact with both Adderall and dextromethorphan. In some cases these drugs are used together with caution and close monitoring by a health care provider. Side effects from selective serotonin reuptake inhibitors (SSRIs) may get worse if you take amphetamine and dextromethorphan. Taking these drugs together could result in side effects such as confusion, dizziness, drowsiness, excessive dry mouth, nausea/vomiting, loss of coordination, muscle weakness, sweating, tremor, and/or palpitations. Report these or other unusual side effects immediately.
Adipex (Phentermine) Advair (fluticasone with salmeterol) Using these together must be done with caution because additive side effects may occur. In combination, these drugs can increase the risk of a fast heart rate, nervousness, palpitations, problems with sleep or other side effects.
Adipex (Phentermine) Allopurinol (Zyloprim) Yes. Always drink plenty of water with the Allopurinol. If you are using the allopurinol for treatment or prevention of gout, please ask your physician for dietary recommendations, to avoid products that can aggravate your condition.
Adipex (Phentermine) Amrix (Cyclobenzaprine) Yes,. But if you have heart disease, talk to your doctor before taking any weight reduction product like Adipex. Always take this early in the day. Muscle relaxant Amrix can cause drowsiness. Only take this if you do not have to be alert.
Adipex (Phentermine) Bactrim (Sulfamethoxazole with Trimethoprim) Yes.
Adipex (Phentermine) Delsym (Dextromethorphan, DM) Yes.
Adipex (Phentermine) Dilantin (Phenytoin) Yes. Take Adipex early each morning. If you have high blood pressure or heart problems, talk to your doctor before taking any weight loss medication, as most can increase the heart rate. Take Dilantin as instructed, and do not skip or change doses without physician instructions.
Adipex (Phentermine) Disulfiram (Antabuse) Yes. They may be taken together. Do not drink alcohol with these medications.
Adipex (Phentermine) Flexeril (Cyclobenzaprine) Yes.
Adipex (Phentermine) Levofloxacin (Levaquin) Yes. They may be taken together if needed.
Adipex (Phentermine) Losartan (Cozaar) One of the many significant side effects of phentermine (Adipex) is hypertension (high blood pressure) in addition to several types of heart dysfunctions. I would suggest speaking with your physician about this situation, in particular if the two drugs were prescribed by different doctors. Even though there are no direct drug interactions between the phentermine and losartan (Cozaar), why take a drug that causes other problems and forces you to have to take more drugs?
Adipex (Phentermine) Lunesta (Eszopiclone) Yes. Only take the Adipex in the morning and the Lunesta at bedtime, or when you can devote 6-8 hours to sleep.
Adipex (Phentermine) Micardis HCT (Telmisartan with Hydrochlorothiazide) While there are no direct drug interactions between Adipex and Micardis HCT, the weight loss drug can increase heart rate and stress your heart. Talk to the physician who prescribed the Micardis before taking Adipex. If you take both, closely monitor your blood pressure and pulse rate.
Adipex (Phentermine) Neurontin (Gabapentin) Yes. Take the Neurontin just as prescribed and the phentermine early in the day.
Adipex (Phentermine) Simvastatin (Zocor) There are no direct drug interactions between simvastatin (Zocor) and phentermine (Adipex). Changing the diet or the way one cooks, can influence both the BMI and cholesterol levels.
Adipex (Phentermine) Propranolol (Inderal) Do not take propranolol (a beta-blocker) and phentermine (a sympathomimetic) together without talking to your health care professional.
Adipex (Phentermine) Tessalon (Benzonatate) Yes. Take Tessalon only as needed for cough.
Adipex (Phentermine) Tramadol (Ultram) Yes. There are no direct drug interactions between Adipex (phentermine) and tramadol (Ultram).
Adipex (Phentermine) Zyrtec (Cetirizine) Yes but if you have high blood pressure, talk to your doctor before taking Adipex.
Advil Cold & Sinus (Non-drowsy) (Ibuprofen with Pseudoephedrine) Zyrtec (Cetirizine) Yes, if Zyrtec is the plain version. Take the Advil product with food or milk. If you have high blood pressure or heart problems, do not take any oral decongestant (like pseudoephedrine) without first talking to your physician.
Advil Cold & Sinus
(Non-drowsy) (Ibuprofen with Pseudoephedrine)
Nasonex (Mometasone) There are no direct drug interactions between Advil Cold & Sinus and Nasonex. You may use them together. If you have high blood pressure or heart problems, do not take any oral decongestant (like pseudoephedrine) without first talking to your physician.
Advil Congestion (Ibuprofen with Phenylephrine) Hydrocodone-APAP (Lortab) Yes. The hydrocodone solution can cause drowsiness and constipation. The Advil product has an oral decongestant which could cause those with heart disease or high blood pressure some problems.
Advil PM Metformin Yes. Take metformin with meals. Take Advil PM bedtime as needed.
Afrin (Oxymetazoline) Nasal Spray Ativan (Lorazepam) Yes. Use both as needed. Use Afrin no more than twice daily or for no more than 3 days in a row. Ativan can cause drowsiness.
Afrin (Oxymetazoline) Nasal Spray Ativan (Lorazepam), Lopressor (Metoprolol) and Norvasc (Amlodipine) Afrin, or any decongestant, constricts capillaries and other blood vessels to reduce congestion. This can cause blood pressure to increase. Talk to your physician before using Afrin. If you get permission to use Afrin, use it for no more than 2 or 3 days.  If you use it longer, you can get rebound congestion. This type of congestion is more pronounced than typical head cold congestion. Ativan can cause drowsiness.
Afrin (Oxymetazoline) Nasal Spray Cetirizine (Zyrtec) Yes. Cetirizine is a long-acting antihistamine, so these two work to relieve different symptoms. Do not use Afrin for more than 2 or 3 days in a row. Use both as needed or as prescribed by your physician.
Afrin (Oxymetazoline) Nasal Spray Sudafed (Pseudoephedrine)

Taking pseudoephedrine with Afrin can increase the risk of high blood pressure, nervousness, palpitations, problems with sleep or other side effects. A safe alternative would be to use saline nasal spray in place of the Afrin.

Alavert D (Loratadine with Pseudoephedrine) Tramadol (Ultram) Yes. They may be taken together if needed. Tramadol can cause drowsiness. If you have high blood pressure or heart disease, talk to your doctor before taking oral decongestants (like pseudoephedrine).
Aleve (Naproxen) Percocet (Acetaminophen with Oxycodone) Yes. Normally these are not given together, as they are both for pain, although Aleve may be used as an anti-inflammatory medication. Take these only as needed. Percocet can cause drowsiness. Take Aleve with food or milk to prevent stomach upset.
Aleve Cold and Sinus (Naproxen with Pseudoephedrine)  Hydrocodone (Norco, Vicodin, Lortab) Take each of these only as needed. Hydrocodone can cause drowsiness. Be careful if you must be alert. Take the Aleve product with food or milk. If you have high blood pressure or heart problems, talk to your doctor before taking this or any oral decongestants.
Aleve D (Naproxen with Pseudoephedrine) Guaifenesin PE (Robitussin w/phenylephrine) No, do not take these together. Taking pseudoephedrine with phenylephrine at the same time can increase the risk of high blood pressure, nervousness, palpitations, problems with sleep, or other serious side effects.
Aleve D (Naproxen with Pseudoephedrine) Lithium (Eskalith) and Prozac (Fluoxetine) Talk with your doctor before you take Aleve. The risk is low, but you could develop stomach upset and bleeding if Aleve-D and Prozac (or any SSRI, selective serotonin reuptake inhibitor) are taken together regularly. Report stomach upset that continues to be bothersome, or any signs of bleeding (like unusual dark tarry stools). Side effects from Lithium may get worse if you take Aleve (an NSAID, nonsteroidal anti-inflammatory drug). Although an interaction is possible, these drugs may be used together with careful monitoring. Promptly notify your prescriber if you experience increased tremor, changes in vision, confusion, excessive thirst, slurred speech, difficulty walking or other unusual reactions. Many nonprescription products contain NSAIDs; read labels carefully. Do not take nonprescription NSAIDs without talking to your doctor. Eye or skin products containing NSAIDs should not interact with Lithium.
Aleve D (Naproxen with Pseudoephedrine) Metoprolol (Toprol or Lopressor) Aleve D contains an oral decongestant with the NSAID. Generally, metoprolol (Toprol or Lopressor) is indicated for hypertension or certain heart conditions. Oral decongestants should not be taken unless prescribed by your physician, if you have any type of heart related issue.
Aldactone Zyrtec D and Nasonex Spray Yes. Normally Aldactone is given once daily in the morning. Use Zyrtec and Nasonex as needed for allergy symptoms. Drink plenty of water, especially when using the antihistamine. When taking diuretics and antihistamines, your body dries out quickly.
Aleve (Naproxen) Allegra D (Fexofenadine with Pseudoephedrine) Yes. They may be taken together if needed. Take Aleve with food or milk to protect the stomach. If you have high blood pressure or heart disease, talk to your doctor before taking any oral decongestant such as pseudoephedrine.
Aleve (Naproxen) Atarax (Hydroxyzine hcl) Yes. Take Aleve with food or milk to avoid stomach upset. Atarax can cause drowsiness.
Aleve (Naproxen) Ceftin (Cefuroxime) Yes. Take Ceftin until the prescription is finished. Take Aleve as needed with food or milk to avoid stomach upset.
Aleve (Naproxen) Cheratussin AC (Codeine with Guaifenesin)
Yes. Take these only as needed. Take Aleve with food or milk. The cough syrup can cause drowsiness. Drink plenty of water.
Aleve (Naproxen) Metronidazole (Flagyl) Yes. Take Aleve when needed and metronidazole until finished. Take both with food or milk. Aleve can cause stomach upset, and metronidazole can leave an unpleasant taste in your mouth.
Aleve (Naproxen) Zyrtec (Cetirizine) Yes. Take Aleve with food or milk to avoid stomach upset. Take only as needed.
Allegra (Fexofenadine) Alcohol No. I do not recommend drinking alcohol with any medication. Antihistamines, including the long-acting, nonsedating types like Allegra, have drowsiness as the #1 side effect. Adding alcohol increases the chance of sleepiness and loss of alertness.
Allegra (Fexofenadine) Allopurinol (Zyloprim) There are no direct drug interactions between allopurinol (Zyloprim) and Allegra (fexofenadine). If your doctor did not give you a diet to follow, ask for a dietitian consult. Avoid alcohol while taking allopurinol. Take Allegra as needed.
Allegra (Fexofenadine) Advil PM (Ibuprofen with Diphenhydramine) Yes, but there is a duplication of the antihistamines. Allegra is a long-acting drug. Diphenhydramine is short-acting. Advil PM should only be taken at bedtime. Normally Allegra is taken in the morning.  If this is how you are taking these, there should not be a problem.  Taking multiple antihistamines can cause excessive drowsiness.
Allegra (Fexofenadine) Ambien (Zolpidem) Yes. Allegra may be taken once or twice daily. Take Ambien at bedtime when you can devote eight hours for sleep. Taking them at the same time could increase drowsiness.
Allegra (Fexofenadine) Atarax (Hydroxyzine) Although there are no direct drug interactions, both are antihistamines. Taking the two together would increase the side effects, especially drowsiness. Talk to your doctor before taking both. If you do take these, be careful if you must be alert. Drink extra water, as these can dry out your mucous membranes.
Allegra (Fexofenadine) Celexa (Citalopram) Yes. Allegra is not supposed to make you drowsy, but the most common side effect is drowsiness.
Allegra 24 (Fexofenadine) Chlortrimeton D 12hrs (Chlorpheniramine Maleate with Pseudoephedrine) The numbers on the names of these drugs indicate the length of action each has. Both are long acting antihistamines. There are not any interactions but there would be duplication of therapy and an increase in the chance of drowsiness. If you have high blood pressure or heart disease, speak to your doctor before taking oral decongestants.
Allegra (Fexofenadine) DayQuil with Phenylephrine 5mg There are several formulas of Vicks DayQuil. Does the one you have contain an antihistamine? If not, and you do not have high blood pressure or heart problems, it should be OK. Allegra's effectiveness can be reduced by grapefruit, orange juice and apple juice, so avoid them.
Allegra (Fexofenadine) Effexor (Venlafaxine), Lamictal (Lamotrigine) and Trileptal (Oxcarbazepine) There is a very slight chance of a minor interaction with Trileptal and Lamictal. Trileptal seems to decrease Lamictal blood levels in some people, making the Lamictal not work as well. Talk with your doctor. Blood tests can check the levels of these drugs. Allegra and Effexor have no problems with any of the others.
Allegra (Fexofenadine) Lexapro (Escitalopram)and Birth Control Yes. Take Lexapro and oral contraceptive at the same time daily. This will keep the blood levels of these drugs as constant as possible.
Allegra (Fexofenadine) Omeprazole (Prilosec) Yes.
Allegra (Fexofenadine) Unisom (Doxylamine) Yes. Normally fexofenadine is taken in the morning. It is a long-lasting antihistamine that is not supposed to cause as much drowsiness as others but if you take it near the same time as the doxylamine, drowsiness could be increased. Any sleeping aid (like doxylamine) should only be taken when you can devote eight hours for sleep.
Allegra (Fexofenadine) Sudafed (Pseudoephedrine) Yes. In fact, the product Allegra-D is this very combination. If you have high blood pressure or heart problems, talk to your doctor before taking any oral decongestant like Sudafed.
Allegra D (Fexofenadine with Pseudoephedrine) Aleve (Naproxen) Yes. Take Aleve as needed with food or milk to avoid stomach upset. If you have high blood pressure or heart problems, talk to your doctor before taking any decongestant (like pseudoephedrine).
Allegra D (Fexofenadine with Pseudoephedrine) Hydrocodone (with acetaminophen: Norco, Vicodin, Lortab, Lorcet) Yes. They may be taken together. If you have high blood pressure or heart problems, talk to your doctor before taking any oral decongestant like Allegra D. The pseudoephedrine can cause blood pressure to increase. Hydrocodone can cause drowsiness. Take these only as needed.
Ambien (Zolpidem) Atarax (Hydroxyzine) The problem is a compounding of the main side effect -- drowsiness. These drugs must be used together with caution, if you must take them both near the same times (within 6 hours of each other). You may feel drowsy when taking these drugs together. Do not drive or operate machinery until you know how these drugs affect you. Do not take Atarax to help you sleep if you are already taking Ambien. Check with your health care professional first.
Ambien (Zolpidem) Diclofenac (Voltaren) Yes. Take diclofenac with food to avoid stomach upset. Take Ambien as needed for sleep, but only if you can devote eight hours for sleep. Avoid alcohol.
Ambien (Zolpidem) Hydrocodone Any codeine derivative can cause drowsiness. Ambien is for sleep, and should only be taken if you can devote eight hours for sleep. Taking both can increase the likelihood of drowsiness throughout the day.
Ambien (Zolpidem) Meridia (Sibutramine) Yes. You are taking these properly: Meridia in the morning and Ambien at night. Monitor your blood pressure while on Meridia, as it can cause hypertension, palpitations and tachycardia. Take Ambien only when needed and when you can devote eight hours for sleep.
Ambien (Zolpidem) Muscle Relaxants Yes. Most muscle relaxants can cause drowsiness. And Ambien is designed to cause sleepiness, so there is an increased likelihood of daytime drowsiness or a loss of attention causing difficulty with your actions during the day. Be careful getting out of bed at night.
Ambien with HCTZ (Hydrochlorothiazide) Atenolol (Tenormin) Although there is a possible drug interaction between HCTZ  and atenolol, these drugs may be used together. There is actually a combination product that contains both of these drugs (Tenoretic). Both treat high blood pressure, though HCTZ is really a diuretic. If blood pressure drops too low while taking these medications, you may become dizzy or feel faint. To limit this, do not stand or sit up too quickly. Contact your prescriber if you have dizziness that does not go away. Ambien may be taken with either of the others without problem.
Amoxicillin Metformin (Glucophage)and Spironolactone (Aldactone) Yes. Take amoxicillin until the prescription is finished.
Antibiotics Amiodarone (Cordarone) There are some antibiotics, antifungal and antiviral that interact with amiodarone: amphotericin B, any -avir type antiviral, any -azole type antifungal, floxacin type antibiotics and some -mycin type antibiotics.
Antihistamines Expectorant Yes. Drink plenty of water. Take both as needed.
Antihistamines Methotrexate Yes. There are no direct drug interactions between methotrexate and any common short- or long-acting antihistamine (Benadryl, Allegra, Zyrtec, Claritin). Take the antihistamines as needed and the methotrexate as your physician has ordered. Swallow it with a full glass of water.
Antihistamines Nasal Decongestant Yes, as long as you have no reasons to avoid either type of medication (high blood pressure, prostate or urinary retention problems). It is common to find both antihistamine and decongestant in the same formulation.
Armour Thyroid Metronidazole (Flagyl) There are no direct drug interactions between Armour Thyroid (desiccated thyroid) and metronidazole (Flagyl). I would not take them together, as the thyroid product should be taken at least a half hour before food and the metronidazole is best taken with food.
Armour Thyroid Seven Day Rapid Yeast Relief Yes. The Yeast Relief product is normally taken twice daily, on empty stomach. Take the thyroid product at least 30 minutes before the other.
Armour Thyroid Vibramycin (Doxycycline) Yes. Normally thyroid products are taken early in the morning,
30 minutes prior to breakfast.
Armour Thyroid 30 Cold Medications, Decongestants or Nasal Sprays Decongestants like pseudoephedrine, phenylephrine, phenylpropanolamine and oxymetazoline (Afrin) are compatible with thyroid. Any decongestant can raise your blood pressure and heart rate. Afrin should be used for only 2 to 3 days to avoid rebound congestion. Also use Ocean (saline) nasal spray with thyroid to treat nasal congestion. Avoid antihistamines while taking thyroid, unless your physician recommends one.
Aspirin or Tylenol (Acetaminophen) Valtrex (Valacyclovir) Yes. If you are taking Tylenol, the the maximum daily limit is 3000mg, 6 extra strength tablets per day.
Atarax (Hydroxyzine HCL) Methylprednisolone (Medrol) Yes. Take Medrol with food or milk as prescribed. Normally a patient is started with a higher daily dose and weaned down until stopped. The Atarax may cause drowsiness. Take it as needed.
Atenolol (Tenormin) Celexa (Citalopram), Ativan (Lorazepam) and Mobic (Meloxicam) Two possible drug interactions involve Mobic. Taking Celexa and Mobic together can increase risk of bleeding. Mobic can interact with atenolol and decrease effectiveness of the blood pressure medication. Check your blood pressure regularly. Talk to your doctor about Mobic and the chance of bleeding. Ativan can cause drowsiness. Inform all your health care providers of your medications, including over-the-counter medicines and vitamins. 
Atenolol (Tenormin) Furosemide (Lasix) An interaction is possible, but these drugs can be used together.  Antihypertensive agents are drugs used to treat high blood pressure, like atenolol (a beta blocker) and furosemide (a diuretic).  If blood pressure drops too low while taking these medications, you may become dizzy or feel faint. To limit this, do not stand or sit up too quickly.  Contact your doctor if you have dizziness that does not go away. Take these as directed.
Atenolol (Tenormin) Over-the-Counter Sleep Aid The most common over-the-counter sleep aid is diphenhydramine (Benadryl/Nytol/Sominex). Atenolol is compatible with diphenhydramine. Be sure you can devote eight hours for sleep.
Atenolol (Tenormin) Protonix (Pantoprazole) Yes. They may be taken together if needed.
Ativan (Lorazepam) Benadryl (Diphenhydramine), Mucinex (Guaifenesin), Proventil (Albuterol) inhaler, Pantoprazole (Protonix) and Allegra (Fexofenadine) Yes. Drink plenty of water with these medications. The biggest concern is the increased chance of drowsiness throughout the day.  Be careful if you must be alert.
Ativan (Lorazepam) Celebrex (Celecoxib) Yes. Celebrex is a very powerful NSAID known to cause heart problems and anxiety. If you are taking Celebrex and notice rapid heart rate or chest tightening, contact your physician.
Ativan (Lorazepam) Cough and Chest Congestion Syrup Yes. Most cough and chest congestion medications use two products: dextromethorphan and guaifenesin. Drink plenty of water with any cough and congestion medications. Lorazepam can cause drowsiness.
Ativan (Lorazepam) Pristiq and Ambien Taking Ativan and Ambien together is a duplication of therapy. Drinking alcohol with any of these can cause extra drowsiness and with the Pristiq, can increase the central nervous system effects. Take Pristiq at the same time daily, and lorazepam and Ambien as needed.
Ativan (Lorazepam) Zoloft (Sertraline) Yes. Both can cause drowsiness. Drinking alcohol or taking other central nervous system depressants can cause extra drowsiness. Take these as prescribed, and do not stop taking Zoloft or change the dose without physician direction.
Augmentin (Amoxicillin with Clavulanic Acid) Cyclobenzaprine (Flexeril) Yes. They may be taken together. Take Augmentin until finished with food or milk to help prevent diarrhea. Cyclobenzaprine can cause drowsiness.
Augmentin (Amoxicillin with Clavulanic Acid) Prescription Diet Pills Yes. There are no drug interactions with antibiotics -- particularly Augmentin -- with the most common diet drug Adipex (phentermine).  Take Augmentin with food or milk until finished.
Augmentin and Guaifenesin Codeine If these are the only medications you take and you are not allergic to penicillins or codeine products, you should be able to take these together. Drink plenty of fluids with the cough syrup and take the Augmentin with food or milk to avoid stomach upset and diarrhea.
Azithromycin (Zithromax) Abilify Yes. There are no direct drug interactions between Zithromax and Abilify (aripiprazole). They may be taken together if needed.
Azithromycin (Zithromax) Bactrim DS (Sulfamethoxazole with Trimethoprim) Yes. Even though they are both antibiotics, they work by different mechanisms and have a different spectrum of activity. Take both until finished, and drink plenty of water with the Bactrim.
Azithromycin (Zithromax) Benadryl (Diphenhydramine), Chantix (Varenicline), Vitamins, Metronidazole (Flagyl) and Benzonatate (Tessalon) Yes. Benadryl and benzonatate can cause drowsiness. Azithromycin  and metronidazole  are antibiotics and must be taken until gone. Take the Chantix and your vitamin daily at the same time.
Azithromycin (Zithromax) Codeine Yes. Take the azithromycin until it is done. The codeine may cause drowsiness and upset the stomach.
Azithromycin (Zithromax) Coricidin Yes.
Azithromycin (Zithromax) Methylprednisolone (Medrol) Yes. Normally methylprednisolone is given in a decreasing dose scheduled over several days. Take it with food or milk to avoid stomach upset. Azithromycin is usually prescribed once daily for 5 days. Take both until the prescriptions are finished or as directed by your physician.
Azithromycin (Zithromax) Norvasc (Amlodipine) yes. Take the Norvasc every day as prescribed by your doctor.
Azithromycin (Zithromax) Phenergan with Codeine (promethazine with codeine) Yes. Take Azithromycin until finished and cough syrup as needed.
Azithromycin (Zithromax) Promethazine DM (Phenergan w/dextromethorphan) Yes. 
Azithromycin (Zithromax) Ranitidine (Zantac) Yes. There are no direct drug interactions between ranitidine (Zantac) and Zithromax (azithromycin).
Azor (Amlodipine with Olmesartan) Pseudoephedrine (Sudafed) No. Azor is for high blood pressure. Pseudoephedrine can increase blood pressure, or increase the risk of palpitations or other side effects. Never take an oral decongestant when you have high blood pressure, without talking to your physician first.
Azor (Amlodipine with Olmesartan) Singulair (Montelukast) Yes. Azor is normally prescribed in the morning and the Singulair in the evening.
Benicar (Olmesartan) Dextromethorphan Yes. Take the Benicar daily as directed and the DM when needed for coughs.
Benicar (Olmesartan) Hydroxyzine (Atarax) Yes. 
Benicar (Olmesartan) Phenytoin (Dilantin) Yes. Take both of these as directed and do not skip doses.
Benicar (Olmesartan) Lasix (Furosemide) Yes. But if you have Benicar HCT, inform your doctor that you already take a diuretic (Lasix), as the HCT part adds hydrochlorothiazide, which is a diuretic.
Benicar (Olmesartan) Robitussin DM (Guaifenesin with Dextromethorphan) Yes. Take Benicar at the same time each day and Robitussin as needed. Increase water intake, and be careful if you become drowsy.
Benicar (Olmesartan) Triamterene (Dyrenium) A possible interaction -- concurrent use of angiotensin II receptor blockers (ARBs) like Benicar and potassium-sparing diuretics (like triamterene) may result in hyperkalemia, too much potassium in the body. A common symptom is leg cramps. The only way to know your potassium level is a blood test. If you notice cramping, contact your doctor.
Benylin (Dextromethorphan) Paxil (Paroxetine) Yes, but additive drowsiness may occur. Take Benylin only as needed, and see how this affects you before you drive or have to be alert. Do not stop the Paxil except with the supervision of your doctor.
Benzonatate (Tessalon) A Cough Suppressant? This would depend on what cough suppressant. Benzonatate with guaifenesin and dextromethorphan (Robitussin DM) is fine. There are no drug interactions, and the cough suppressants work differently. Taking benzonatate with any of the codeine-related products could be a problem. Although an interaction is possible, these drugs are sometimes used together. Side effects from the codeine may get worse if you take benzonatate. If you notice slurred speech, confusion, severe weakness or difficulty breathing while taking these medicines, contact your health care provider immediately.  Benzonatate can cause drowsiness.
Benzonatate (Tessalon) Cheratussin (Codeine with Guaifenesin) Although an interaction is possible, benzonatate and Cheratussin are sometimes used together. Side effects from the cough syrup may get worse if you take benzonatate. If you notice slurred speech, confusion, severe weakness or difficulty breathing while taking these medicines, contact your health care provider immediately. Take both of these only as needed.
Benzonatate (Tessalon) Something for a Headache Tylenol (acetaminophen) is a good choice for headaches, unless there is a reason not to be taking it (liver damage or allergy). Follow label directions, and take less than 3000mg per day.
Benzonatate (Tessalon) Sudafed (Pseudoephedrine) Yes. If you have heart problems or high blood pressure, talk to your physician before taking Sudafed. Benzonatate can cause drowsiness.
Benzonatate (Tessalon) Thera Flu (acetaminophen, diphenhydramine and phenylephrine) Thera Flu is not intended to help a cough. The ingredients stop flu and allergy symptoms (runny nose), fever, pain, headache and congestion. There would be no interactions between these, aside from a chance to increase drowsiness. If your only symptom is a cough, try a plain cough suppressant like dextromethorphan (DM). This can be found in many cough syrups and in a long-acting product like Delsym. This may be used along with benzonatate. Drink plenty of water. If the cough persists, contact your physician.
Benzonatate (Tessalon) Allegra (Fexofenadine), Methylprednisolone (Medrol), Factive (Gemifloxacin), Xopenex and Unithroid (Levothyroxine) Yes. Take Unithroid at least 30 minutes before breakfast with Factive. Take Allegra in the morning with methylprednisolone or just after meals. Take the antibiotic and steroid until finished. If you are to take the benzonatate once daily, take it at bedtime. This would stop the cough and help you sleep. For fever, take Tylenol. Follow up with your physician.
Biaxin (Clarithromycin) Atenolol (Tenormin) and Hydrochlorothiazide Yes. Take Biaxin with food if it upsets your stomach and until the prescription is finished. Take atenolol and HCTZ at the same times every day. Do not stop taking these without instruction from your physician.
Biaxin (Clarithromycin) Lexapro (Escitalopram) Although an interaction is theoretically possible, Biaxin and Lexapro  may be used together. Taking these drugs together might worsen escitalopram-related side effects such as confusion, dizziness, drowsiness, excessive dry mouth, nausea/vomiting, muscle weakness, sweating, tremor and/or palpitations. Notify your physician if you have any of these symptoms.
Biaxin XL (Clarithromycin) Tessalon (Benzonatate) Yes. Take Biaxin with food if it upsets your stomach and until the prescription is finished. Take Tessalon as needed for cough, with plenty of water. This can cause drowsiness.
Black Cohosh (Cimicifuga Racemosa) Lyrica (Pregabalin) Yes. They may be taken together if needed. But herbal products are not regulated by or inspected by the FDA. Black Cohosh may have other ingredients that could affect the Lyrica. Read the label carefully. Purchase your herbals at reputable places. Always let your health care providers know when you add to or change your medication regimen.
Buscopan (Butylscopolamine with Paracetamol) Citalopram (Celexa) Buscopan, a hyoscine medication unavailable in the United States, is similar to Levsin (hyoscyamine). There are no direct drug interactions between citalopram and Levsin, so I would say that the Buscopan would be the same, and they would be safe to take together.
Buscopan (Butylscopolamine with Paracetamol) Fluoxetine (Prozac) Buscopan is unavailable in the United States. The closest would be two separate drugs, hyoscyamine (Levsin) and acetaminophen (Tylenol).  Paracetamol is a European brand of acetaminophen. There are no direct drug interactions between Buscopan and fluoxetine. They may be taken together. The same is true for both Levsin and Tylenol with fluoxetine.
Buscopan (Butylscopolamine with Paracetamol) Orlistat (Xenical) Buscopan is unavailable in the United States. The closest product, scopolamine, has no direct drug interactions with orlistat. They may be taken together. Buscopan is the butyl salt of scopolamine, and I would assume the drug interaction profile with orlistat to be similar. Talk to your physician or pharmacist.
Carvedilol (Coreg) Amlodipine (Norvasc) Yes. These are antihypertensive medications to treat high blood pressure. Physicians often use several drugs to treat the same condition. This allows for lower doses and less chance of side effects.
However, if blood pressure drops too low while taking these, you may become dizzy or feel faint. To limit this, do not stand or sit up too quickly. Contact your doctor if you have dizziness that does not go away. Always ask your doctor about any problems that occur after starting new medications.
Carvedilol (Coreg) Citalopram (Celexa) There is a chance for a very minor interaction. Contact your prescriber if you experience dizziness which does not go away, shortness of breath, persistent slow heart rate while resting or new or increased swelling of your legs or ankles while taking carvedilol.
Ceftin (cefuroxime) Aleve (Naproxen) Yes. Take Ceftin until the prescription is finished. Take Aleve as needed with food or milk to avoid stomach upset.
Cefuroxime (Ceftin) Mucinex (Guaifenesin) or Comtrex (Acetaminophen, Brompheniramine, Pseudoephedrine) Yes. All three may be taken together. Plain Mucinex is an expectorant, so drink plenty of water. If you have high blood pressure or heart disease, talk to your doctor before taking any oral decongestant (the pseudoephedrine part of Comtrex). Take the antibiotic (cefuroxime) until finished.
Celebrex (Celecoxib) A Nasal Decongestant Yes. Take Celebrex with food at the same time every day. Use nasal decongestant no more than three days in a row to avoid rebound congestion. Normal saline nasal spray can be used long term, as needed.
Celebrex (Celecoxib) Colchicine Yes. They are commonly prescribed together. Take Celebrex with food. If you develop diarrhea, contact your physician. Colchicine can cause loose stools if taken in high doses or over a long time.
Celebrex (Celecoxib) Fluoxetine (Prozac) While the risk is low, there may be a potential to develop stomach irritation and bleeding if nonsteroidal anti-inflammatory drugs (NSAIDs) -- like Celebrex -- and selective serotonin reuptake inhibitors (SSRIs) -- like fluoxetine -- are regularly taken together. If these are prescribed by different physicians, make sure they know about all the medications you take. The doctor(s) may believe these are the best two drugs for your conditions. Take these as prescribed.  Report stomach irritation that continues to be bothersome, or any signs of bleeding (like unusual dark, tarry stools) to your health care provider. Always take Celebrex with a meal or large glass of milk.
Celebrex (Celecoxib) Lipitor (Atorvastatin) Yes. They may be taken together. Take Celebrex with food or milk to avoid stomach upset.
Celebrex (Celecoxib) Phentermine (Adipex) Yes. Always take Celebrex with food or milk to prevent stomach upset. If you have high blood pressure or heart problems, talk to your doctor before taking phentermine.
Cephalexin (Keflex) Alcohol Yes.
Cephalexin (Keflex) Ambien (Zolpidem) Yes. Take cephalexin until finished. Take Ambien when needed for sleep and you have at least 7-8 hours to devote for sleep. Be careful when you first get up.
Cephalexin (Keflex) Benzonatate (Tessalon) Yes. Take cephalexin until finished and benzonatate with water as needed.
Cephalexin (Keflex) Erythromycin (Erygel, Eryderm) Yes. Take cephalexin until finished, and use a good sun screen if you have to be outdoors.
Cephalexin (Keflex) Fexofenadine (Allegra) Yes. Take the cephalexin until the prescription is finished.
Cephalexin (Keflex) Valium (Diazepam) Yes. Take the antibiotic until finished. Take diazepam as needed. It can cause drowsiness.
Chantix (Varenicline) Flecainide (Tambocor) Yes. Follow the directions on the Chantix. Take advantage of any help or advice to stop smoking. If you have specific questions about this drug, call the toll-free number you were given. Lifestyle changes and a smoking cessation coach could be helpful.
Chantix (Varenicline) Meloxicam (Mobic) and Vicodin (Acetaminophen with Hydrocodone) Yes. They may be taken together. If your stomach gets upset, take with food or milk. Vicodin can make you drowsy. Follow Chantix instructions. Of you notice side effects, contact your physician.
Chantix (Varenicline) Pristiq (Desvenlafaxine) and Phentermine (Adipex) Congratulations on your decision to quit smoking. Avoid alcohol. Do not stop Pristiq unless directed by the physician. Follow instructions on Chantix, and take advantage of any available help or advice to stop smoking. Adipex is recommended to be taken only for a short time. If you have heart or blood pressure problems, talk to your doctor.
Chantix (Varenicline) Topamax (Topiramate) Yes. Congratulations on your decision to quit smoking. These drugs should not be taken if you are pregnant or breastfeeding without an OK from your ob/gyn or pediatrician. Notify your doctor of any behavior or mood changes. Nausea may be a concern and if it is too bad, contact your doctor.
Chantix (Varenicline) Toprol XL (Metoprolol Succinate) Yes.
Cheratussin AC (Guaifenesin with Codeine) Allegra D (Fexofenadine with Pseudoephedrine) Yes. They may be taken together with plenty of water. Codeine and Allegra can cause drowsiness. If you have high blood pressure or heart problems, talk to your physician before taking these.
Cheratussin AC (Guaifenesin with Codeine) NyQuil There is a duplication of product types when you compare these medications. Cheratussin AC and Vicks NyQuil (acetaminophen, dextromethorphan, doxylamine and pseudoephedrine) both contain cough suppressants. You may feel drowsy when taking these. Many nonprescription cough and cold, allergy and sleep products contain doxylamine; read labels carefully. Do not drive or operate machinery until you know how these drugs affect you. If you notice slurred speech, confusion, severe weakness or difficulty breathing while taking these drugs, contact your health care provider immediately. Take NyQuil only at bedtime.
Chlor-Trimeton NyQuil No. It's too much antihistamine. Take one or the other.
Chlordiazepoxide (Librium)  Woman's Multivitamin That depends upon the ingredients in the multivitamin. If there are minerals as well as vitamins, there could be an interaction. Magnesium, a mineral found in many multivitamins with minerals, can cause minor problems with medications that can cause drowsiness. Although an interaction is possible, these drugs may be used together and rarely cause problems. Rarely, you may feel drowsy when taking these drugs. Do not drive or operate machinery until you know how these drugs affect you. Discuss troublesome side effects with your doctor.
Ciprofloxacin (Cipro) Coreg (Carvedilol) Yes. Do not stop taking the carvedilol unless
the doctor instructs.
Ciprofloxacin (Cipro) Flexeril (Cyclobenzaprine) A rare and infrequent interaction may occur between Cipro (ciprofloxacin) and Flexeril (cyclobenzaprine). These drugs may be taken together only under close supervision from your doctor. Taking these drugs together can increase the risk of a dangerous change in heartbeat or heart rhythm. Contact you prescriber immediately if you experience chest pain, dizziness, fainting or falling spells, palpitations, shortness of breath, or a change in your heart beat.
Ciprofloxacin (Cipro) Lisinopril (Zestril/Prinivil) Yes. They may be taken together. Take the Cipro until finished.
Ciprofloxacin (Cipro) Oxycontin (Oxycodone) Yes. Take the Cipro as directed until finished. Take the Oxycontin only as prescribed. Taking more is never a good idea, unless the dosage is increased by the physician.
Ciprofloxacin (Cipro) Robitussin PM Cough and Cold Yes. Cipro does not have any direct drug interactions with any  Robitussin products, including:
  • Robitussin PM (chlorpheniramine, dextromethorphan and pseudoephedrine)
  • Robitussin Cough and Cold (guaifenesin, dextromethorphan and pseudoephedrine)
Take Cipro until finished and the Robitussin products only as needed with plenty of water.
Ciprofloxacin (Cipro) Tramadol (Ultram) Yes. They may be taken together. Take ciprofloxacin until finished and tramadol as needed.
Citalopram (Celexa) Lorazepam (Ativan) and Zyrtec D (Cetirizine with Pseudoephedrine) Yes, but you may feel drowsy when taking these drugs. Do not drive or operate machinery until you know how these drugs affect you. If you have high blood pressure or heart disease, talk to your physician before taking any oral decongestant like pseudoephedrine.
Clarithromycin (Biaxin) Codeine Syrup (Iophen-C NR) Yes. They may be taken together. Take the cough syrup only as needed. It can cause drowsiness and constipation. Drink plenty of water. Take the antibiotic until finished.
Clonazepam (Klonopin) Hydrocodone (Hycotuss or Tussionex) The only issue or interaction that can occur between Klonopin (clonazepam) and hydrocodone (Hycotuss or Tussionex) is excess drowsiness.
Clonazepam (Klonopin) Other Medications Medications of the benzodiazepine class (like clonazepam) have a high likelihood to cause drowsiness. So, any other product (including alcohol, central nervous system depressants or valproic acid drugs) that also causes drowsiness may intensify this effect. Some herbals, such as St. Johns Wort, should also be avoided.
Colchicine Hydrocodone Yes. Hydrocodone can cause drowsiness.
Colon Cleanse Tablets Flecainide (Tambocor) What type of "colon cleanse" tablets? Considering the common colon preparation products we use at the hospital, there are no direct drug interactions between flecainide and bisacodyl (Dulcolax), magnesium citrate (Citrate of Mag) or polyethylene glycol (Golytely, MiraLAX).
Comtrex Deep Chest Cold Hydrocodone BT and Ibuprofen T Band Yes. This formulation of Comtrex contains acetaminophen, as does the hydrocodone, so be careful with the daily total amount of acetaminophen -- no more than 3000mg in 24 hours. Ibuprofen and hydrocodone should be taken with food to avoid stomach upset. Comtrex works best when you drink plenty of fluids.
Coricidin HBP Metformin, Singular, Simvastatin, Carvedilol, Citalopram, Hydrochlorothiazide and Venlafaxine Are all these prescribed by the same physician? Are your blood pressure and diabetes under control? There may be an interaction between metformin (Glucophage) and carvedilol (Coreg). Concurrent use of anti-diabetic agents and beta blockers may result in hypoglycemia, hyperglycemia or hypertension. If your see multiple physicians or pharmacies, discuss with them your drug regimen. You should have no trouble adding Coricidin HBP to this mix, though.
Cold or Allergy Medicine Venlafaxine (Effexor) and Hydrochlorothiazide Venlafaxine does not interact with: long-acting antihistamines (Zyrtec, Allegra, Claritin), short-acting antihistamines (Benadryl, Chlortrimeton), decongestants (Sudafed, Mucinex) or cough medications(DM -- dextromethorphan). Hydrochlorothiazide could be a problem with Sudafed or any oral nasal decongestant. Do not take cough, cold, flu or allergy products containing pseudoephedrine (Sudafed, for instance) without talking to your doctor. Pseudoephedrine can decrease the effectiveness of your heart or blood pressure medications by increasing blood pressure or increasing the risk of palpitations or other side effects. Many prescription and nonprescription products contain pseudoephedrine. Read labels carefully.
Crestor (Rosuvastatin) Black Cohosh (Cimicifuga Racemosa) Yes. They may be taken together if needed.
Cyclobenzaprine (Flexeril)  Hydrocodone-apap (Lorcet or Vicodin) Yes. Both can cause extreme drowsiness. Be careful if you must be alert. Take hydrocodone-apap only as needed.
Cymbalta (Duloxetine) Cough Drops A drug interaction could occur with cough drops containing dextromethorphan (DM). Concurrent use of DM and Cymbalta can result in increased dextromethorphan plasma concentrations and increased risk of serotonin syndrome. Most cough drops contain menthol and/or Vitamin C (ascorbic acid).  There are no interactions with these and Cymbalta.
Cymbalta (Duloxetine) Tylenol PM, Tylenol Extra Strength or Excedrin Migraine Cymbalta may be taken with Tylenol (acetaminophen). The PM part is an antihistamine, diphenhydramine, which with the Cymbalta, can make you extra drowsy. Do not take the Excedrin product with Cymbalta. Some Excedrin formulas have aspirin, and Cymbalta has been shown to increase the chance of bleeding with aspirin. Talk to your doctor about your migraines.
Cymbalta (Duloxetine) Vicoprofen (Hydrocodone with Ibuprofen) Although an interaction is possible, Vicoprofen (hydrocodone with ibuprofen) and Cymbalta (duloxetine) are often used together. Using them together may make you bruise or bleed more easily. Discuss any new or worsening side effects with your health care provider.
Cymbalta (Duloxetine) Wellbutrin (Bupropion) Yes. They may be taken together. Take these medications only as prescribed, and do not stop except by physician direction.
DayQuil Bactrim (Sulfamethoxazole/Trimethoprim) Yes. They may be taken together if needed. Take the Bactrim until finished, with plenty of water. Take the Dayquil only when needed.
DayQuil Midol Vicks DayQuil and Midol are both available in several formulas. With all the possible combinations, interactions are possible but these drugs are often used together. Taking NSAIDs (like the ibuprofen in some DayQuils) may decrease the effect of diuretics in some Midols. Taking these together may also decrease kidney function.
DayQuil Tessalon There are many formulas of Vicks DayQuil. With the "Multi-Symptom" formula, there are no direct drug interactions. There is another antitussive (dextromethorphan) in the DayQuil, but they may be taken together. Tessalon (benzonatate) can cause drowsiness.
DayQuil Valtrex (valacyclovir) Yes.
DayQuil (Pseudoephedrine and Ibuprofen) Zoloft (Sertraline) There is a very minor chance of an interaction. And although the interaction is possible, these drugs are often used together. Using these drugs together may make you bruise or bleed more easily. Discuss any new or worsening side effects with your physician. Discuss your drug regimen with your health care provider prior to any surgeries or procedures. DayQuil contains an oral decongestant. If you have high blood pressure or heart disease, talk to your doctor before taking.
Delsym Cough Syrup (Dextromethorphan -- DM) Advair Inhaler (Fluticasone with Salmeterol) Yes. They may be used together. Be sure to rinse your mouth after each use of the Advair. Take Delsym only as needed for cough.
Delsym Cough Syrup (Dextromethorphan -- DM) Fluticasone (Flonase) Yes. They may be taken together. Take both no more than twice daily. Drink plenty of water.
Delsym Cough Syrup (Dextromethorphan -- DM) Mucus Relief DM (Guaifenesin with Dextromethorphan) No. Mucus Relief DM (guaifenesin with dextromethorphan) and Delsym (dextromethorphan) should not be taken together.
Both products contain dextromethorphan (DM). You may take plain guaifenesin and Delsym but you should not take multiple products containing DM.
Delsym Cough Syrup (Dextromethorphan -- DM) Lexapro, Wellbutrin and Klonopin There are no direct drug interactions but if Klonopin (clonazepam) is treating epilepsy, avoid Wellbutrin (bupropion). You also have increased chance of drowsiness or loss of alertness. If you see more than one physician or have seizure problems, speak to your doctor before taking Delsym.
Delsym Cough Syrup (Dextromethorphan -- DM) Phenergan Yes. There are no direct drug interactions between plain promethazine syrup (Phenergan) and Delsym (dextromethorphan). They may be taken together if needed. Take these only when needed.
Delsym Cough Syrup (Dextromethorphan -- DM) Prednisone Yes. Delsym is a long-acting cough medication usually given twice a day, as needed. Prednisone is normally given once daily in the morning, with food or milk. The prednisone should be taken as instructed by the physician.
Delsym Cough Syrup (Dextromethorphan -- DM) Pristiq (Desvenlafaxine) An interaction is possible. Even so these drugs are often used together for brief periods. Pristiq side effects can get worse if you take DM: restlessness, sweating, tremor, vomiting or other side effects. Do not exceed recommended doses of cough products containing dextromethorphan, and report any troublesome effects that occur.
Delsym Cough Syrup (Dextromethorphan -- DM) Septra Yes. Take Delsym no more than twice daily and only as needed. Take the Septra until finished, with plenty of water. They may be taken together if needed.
Delsym Cough Syrup (Dextromethorphan -- DM) Vicks DayQuil There are really no interactions between these two, but there is duplication of the cough suppressant in any of the formulations with dextromethorphan (DM).
Dhatracin Milk No. Dhatracin is a tetracycline antibiotic made in Malaysia. Tetracyclines should be taken on an empty stomach. Avoid milk, dairy products and vitamins with minerals (especially calcium). Concurrent use of tetracycline and dairy products may result in decreased tetracycline concentrations. Avoid tetracyclines in children whose adult teeth have not come in, as this class of antibiotics could discolor the tooth while still in the gum.
Diflucan (Fluconazole) Levaquin (Levofloxacin) No. These are both antibiotics. Concurrent use may result in an increased risk of QTc prolongation and torsades de pointes. This means the electrical conduction of the heart can be affected. Talk to the prescribing physician(s).
Diflucan (Fluconazole) Librax (Chlordiazepoxide with Clidinium) Yes. Take fluconazole until gone, with food, and watch for a skin rash (sign of drug allergy). Librax can cause drowsiness.
Diflucan (Fluconazole) Medrol (Methylprednisolone) and Cleocin (Clindamycin) Yes. Take Medrol and Diflucan with food until finished.
Diflucan (Fluconazole) Sudafed (pseudoephedrine) Yes. If you have high blood pressure or heart disease, please speak to your physician before taking any oral decongestant like Sudafed.
Diflucan (Fluconazole) Trimethoprim (Trimpex) Yes.
Diltiazem XR (Tiazac, Cardizem) HCTZ (Hydrochlorothiazide) An interaction is possible, but these drugs are commonly used together. They both treat high blood pressure and are referred to as antihypertensive agents. If the blood pressure drops too low while taking these, you may become dizzy or feel faint. To avoid this, do not stand or sit up too quickly. Contact your doctor if you have dizziness that does not go away.
Doxycycline (Vibramycin) Phenylephrine  (in Robitussin PE) Yes. They may be taken together. Take the doxycycline antibiotic until finished. Take phenylephrine when needed. If you have high blood pressure or heart problems, talk to your doctor before taking phenylephrine.
Echinacea Tussin (Guaifenesin) and Citalopram (Celexa) Yes. Drink plenty of water with the echinacea and Tussin. These should only be taken as needed. Take citalopram every day. Do not stop or change dosage without instruction from your physician.
Empirin with Codeine # 4 Sinequan (Doxepin) No. There is a drug interaction. When taking Empirin with Codeine (aspirin, butalbital, caffeine and codeine) with Sinequan, the additive depressant effects can cause respiratory depression (trouble breathing) or hypotension (too low a blood pressure). Talk to your doctor. Make sure all your health care providers know what you take.
Echinacea Lisinopril (Zestril, Prinivil) and Hydrochlorothiazide (HCTZ) Yes. They may be taken together.
Estroven Toprol XL (Metoprolol) Yes. There are no direct drug interactions between Toprol XL and Estroven products -- herbal supplements made with natural ingredients (black cohosh plus soy isoflavones are combined with essential nutrients like calcium, folic acid and B vitamins). Take Toprol daily as directed. Have your blood pressure checked regularly. Save the ingredient panel of the Estroven so you know what it contains.
Estroven Maximum Strength Lamictal  (Lamotrigine) Yes. They may be taken together.
Estroven PMS (Multivitamin, Calcium, Selenium, Black Cohosh, Boron and Magnolia) Focalin (Dexmethylphenidate) and Wellbutrin (Bupropion) I could not find any reference to drug interactions. Take the Estroven by itself, a couple of hours separate from the other two. Do not stop Focalin or Wellbutrin without the direction of your physician.
Evening Primrose Oil (Gamma-Linolenic Acid)  Flecainide (Tambocor)   Yes. They may be taken together if needed. Be sure all your health care providers have a current medication list, including over-the-counter and herbal products.
Excedrin PM (Acetaminophen with Diphenhydramine) Cephalexin  (Keflex) Yes. They may be taken together, but only take Excedrin PM at bedtime if needed. This can cause drowsiness. Take cephalexin until finished.
Excedrin Tension (Acetaminophen with Caffeine) Fluticasone (Flonase) Yes. Taking the Excedrin product late at night may make it harder to sleep. Take this only as needed.
Fexofenadine (Allegra) Oxymetazoline I will assume the oxymetazoline you want to use is the nasal product Afrin. There are no direct drug interactions, but if you have high blood pressure you may want to avoid oxymetazoline, as it constricts blood vessels. This may increase your blood pressure and put an added strain on your heart. Use these only as needed and directed. Oxymetazoline nasal spray should not be used more than 2 or 3 days.
Fexofenadine (Allegra) Ranitidine (Zantac) and Hydroxyzine (Atarax) Yes. The only problem is that hydroxyzine, a short-acting and sedating antihistamine, can cause extreme drowsiness. Taking a long-acting antihistamine like fexofenadine can increase the drowsiness.
Flexeril (Cyclobenzaprine) Ambien CR (Zolpidem) Yes. Both can cause drowsiness. Only take Ambien as needed when you can devote at least eight hours for sleep.
Flexeril (Cyclobenzaprine) Anaprox (Naproxen Sodium) Yes. Take the naproxen with food or milk to prevent stomach upset. Flexeril can cause drowsiness, so be careful if you must be alert.
Flexeril (Cyclobenzaprine) Aspirin Yes. Flexeril, a muscle relaxant, can be taken with most pain relievers, including aspirin. Take enteric-coated aspirin with food. Flexeril can cause drowsiness.
Flexeril (Cyclobenzaprine) Ativan (Lorazepam) Yes, but I would advise against it. Both medications can cause drowsiness and taking them together can cause an additive effect. If you must take them in the same day, be careful particularly if you need to be alert.
Flexeril (Cyclobenzaprine) Benzonatate (Tessalon) Yes. Both can cause drowsiness. Take these only as long as needed.
Flexeril (Cyclobenzaprine) Celebrex (Celecoxib) and Wellbutrin (Bupropion) Yes. Take Celebrex with food to avoid stomach upset. Avoid alcohol. Flexeril can cause extreme drowsiness.
Flexeril (Cyclobenzaprine) Celexa and Morphine Sulphate Yes. All may cause drowsiness. Take Celexa (citalopram) as instructed every day. Take Flexeril and morphine as needed.
Flexeril (Cyclobenzaprine) Cetirizine (Zyrtec) Yes. While these may be taken together, both can cause drowsiness, so you could feel an additive effect. If you must be alert, be careful until you see how you react to these medications.
Flexeril (Cyclobenzaprine) Excedrin Back and Body, and Darvon (Propoxyphene) Yes. Both can cause drowsiness. Propoxyphene is normally prescribed in combination with acetaminophen (Darvocet N). If this is what you have, limit your daily acetaminophen intake to 3000mg. Take these as needed.
Flexeril (Cyclobenzaprine) Excedrin Extra Strength Yes. Take only as needed. As a muscle relaxant, Flexeril can cause drowsiness.
Flexeril (Cyclobenzaprine) Felodipine (Plendil) Yes. Take felodipine at the same time each day. If you eat grapefruit, have it eight or more hours away from the felodipine. Avoid alcohol. Both can cause drowsiness and dizziness. Take cyclobenzaprine as needed. Do not stop felodipine without direction from your physician.
Flexeril (Cyclobenzaprine) Lisinopril (Zestril) Yes. They may be taken together. Flexeril can cause drowsiness, so be careful if you must be alert.
Flexeril (Cyclobenzaprine) Maxzide (triamterene with hydrochlorothiazide) Yes. Take the Flexeril only as needed and be careful if you must be alert. This may cause extreme drowsiness.
Flexeril (Cyclobenzaprine) Metoprolol (Lopressor or Toprol) Yes.
Flexeril (Cyclobenzaprine) Mirapex (Pramipexole) and Clonazepam  (Klonopin) Clonazepam can increase the likelihood of extreme drowsiness that both Flexeril and Mirapex can cause. You may feel drowsy when taking these drugs. This effect may last for a few days even after you stop taking these drugs. Do not drive or operate machinery until you know how these drugs affect you. If you notice slurred speech, confusion, severe weakness or difficulty breathing, contact your physician immediately. Also talk to your doctor if you notice any new or worsening side effects, like  extreme confusion or difficulty staying alert.
Flexeril (Cyclobenzaprine) Ms Contin (Morphine) Yes. Both can cause drowsiness, so taking them together can have an additive effect.
Flexeril (Cyclobenzaprine) Naproxen (Aleve, Naprosyn) Yes. Flexeril can cause extreme drowsiness. Take Naprosyn with food or milk to avoid stomach upset. Take both only as needed.
Flexeril (Cyclobenzaprine) Naproxen (Aleve, Naprosyn) and Dyazide (Triamterene with HCTZ) There is one possible (although infrequent) interaction. Flexeril is fine to take with the other two medications. It can cause drowsiness. Naproxen can interact with Dyazide -- concurrent use of NSAIDs (nonsteroidal anti-inflammatory drugs) like naproxen and thiazide diuretics like HCTZ may make the diuretic (water pill) not work as well, which could increase your blood pressure, because you're retaining fluids. If you must take both and all your physicians are aware of your medications, watch your blood pressure. If there is a change in your pressure, contact your doctor.
Flexeril (Cyclobenzaprine) Percocet (oxycodone with Acetaminophen) Yes. They are commonly used together. Both cause drowsiness. Taking together increases that effect. Take these as needed and never more than instructed.
Flexeril (Cyclobenzaprine) Phenobarbital and Carbamazepine (Tegretol) There is an interaction between carbamazepine and phenobarbital that when taken together may result in decreased carbamazepine effectiveness with loss of seizure control. Most physicians have titrated the doses to offset this problem, so if you have been taking these for a while, do not stop taking either without talking to the physician. All these can cause drowsiness. Avoid alcohol. Take Flexeril as needed.
Flexeril (Cyclobenzaprine) Prozac (Fluoxetine) A possible serious interaction has to do with electrical conduction in the heart muscle -- concurrent use may result in an increased risk of QT prolongation. The two together may also increase the chance of drowsiness. Contact the prescribing physician(s).
Flexeril (Cyclobenzaprine) Robitussin (Guaifenesin) Yes.
Flexeril (Cyclobenzaprine) Sibutramine (Meridia)   Yes. Do not take more of either these medications than prescribed.  Flexeril is a muscle relaxant that can cause drowsiness.
Flexeril (Cyclobenzaprine) Sudafed Sinus and Excedrin PM I would not. There are several formulas of Sudafed sinus. Some have acetaminophen and diphenhydramine. Excedrin PM has acetaminophen and diphenhydramine, so you would be duplicating drugs and side effects. Diphenhydramine helps you sleep and treats sinus allergies. It will make you drowsy. Flexeril is a muscle relaxant that can cause drowsiness. If you are congested, take plain Sudafed and use saline nasal spray. If you have trouble sleeping, take plain diphenhydramine, or arrange the doses of Flexeril to take the last one each day before bedtime. Read your medication labels. Do not exceed the 3000mg per day acetaminophen limit.
Flexeril (Cyclobenzaprine) Sular (Nisoldipine) Yes. As a muscle relaxant, Flexeril can cause drowsiness.
Flexeril (Cyclobenzaprine) Tramadol (Ultram) Yes. Both can cause drowsiness.
Flexeril (Cyclobenzaprine) Tylenol w/Codeine#3 There are no direct drug interactions between Tylenol w/Codeine#3 (acetaminophen with codeine) and Flexeril. Both will cause drowsiness.
Flexeril (Cyclobenzaprine) Voltaren (Diclofenac) and Topamax (Topiramate) Yes. Take Topamax as directed every day, and Flexeril and Voltaren as needed. Take Voltaren with food or milk. Topamax and Flexeril can cause drowsiness.
Flexeril (Cyclobenzaprine) Wellbutrin SR Yes. Take Flexeril at bedtime, as it can cause drowsiness.
Flexeril (Cyclobenzaprine) Wine Yes. Have a designated driver. Flexeril, a muscle relaxant, can causes drowsiness.  Alcohol (wine, beer, liquors) causes drowsiness.
Focalin XR (Dexmethylphenidate) Any Cold Medication Yes. Focalin can be taken with any cold, allergy or sinus medication. Any decongestant, like pseudoephedrine or phenylephrine, can increase heart rate and blood pressure. A common adverse reaction to Focalin is tachyarrhythmia. Any decongestant could make this worse. This is not an interaction, but an increase in the risk of heart problems. Talk with your physician.
Gabapentin (Neurontin) Lodrane D (Brompheniramine with Pseudoephedrine) Yes. If you have high blood pressure or heart disease, please speak to your physician before taking any oral decongestant. The antihistamine part of the Lodrane D may cause drowsiness.
Gabapentin (Neurontin) Methocarbamol (Robaxin), Sertraline (Zoloft) and Bupropion SR (Wellbutrin or Zyban) Taking some of these together could increase the chance and severity of side effects. Do not take bupropion and anticonvulsants together (like gabapentin) without talking to your health care provider if you take this medication for seizures. Bupropion should not be used in people with a known seizure disorder, due to an increased risk of seizures. Notify your prescriber if you notice that bupropion is not working as well for you; some anticonvulsants might reduce bupropion's effectiveness. Because you may feel dizzy, drowsy or more tired when taking these drugs, do not drive or operate machinery until you know how these drugs affect you. Notify your health care provider if you experience confusion, dizziness, falls, changes in mood, unsteadiness or other troublesome side effects. Taking bupropion and sertraline together can be problematic. Although an interaction is possible, these drugs may be used together. Bupropion may also be used with sertraline (and other SSRIs) to decrease side effects, such as loss of sexual desire. Do not drive or operate machinery until you know how these drugs affect you. You may feel drowsy or more tired when taking sertraline and bupropion together. Some side effects from sertraline may get worse if you take bupropion: risk of confusion, loss of coordination, restlessness, sweating, tremor, vomiting or other side effects. Sertraline and bupropion may represent duplicate therapies for mood problems like depression in some patients, but they may also be used together to treat depression that has not responded to either agent alone. Methocarbamol is a muscle relaxant and can cause drowsiness. Added to the others, this may be extreme. If these medications have been prescribed by more than one doctor, be sure to notify each of you doctors (and other health care providers) of all your medications. Your doctors should tell you desired and possible undesired effects of any new medication. Your pharmacists should be monitoring your prescriptions for interactions and inform you of common side effects.
Guaifenesin Codeine and Neurontin (Gabapentin) Yes. They may be taken together. Take guaifenesin with plenty of water. Codeine can cause extreme drowsiness and constipation.
Halcion (Triazolam) Doxepin (Sinequan) Yes. Both can cause drowsiness, so take Halcion only at bedtime for sleep and only as needed. Avoid alcohol.
Halcion (Triazolam) Levofloxacin (Levaquin) Yes. Take the levofloxacin until completion. Halcion should be taken as needed for sleep.  If there is fever, take Tylenol (acetaminophen) up to 3000mg in 24 hours.  Follow the dosage on the bottle.
Hydrochlorothiazide (HCTZ) Benzonatate (Tessalon) Yes. They may be taken together if needed.
Hydrochlorothiazide (HCTZ) Dextromethorphan (DM, Delsym) Yes. Take hydrochlorothiazide in the morning and dextromethorphan only as needed.
Hydrochlorothiazide (HCTZ) Dulcolax (Bisacodyl) Yes.
Hydrochlorothiazide (HCTZ) Gamma-Linolenic Acid (GLA) Yes. These may be taken together if needed.
Hydrocodone Ibuprofen (Vicoprofen) Flexeril (Cyclobenzaprine), Lithium, Lamictal (Lamotrigine) and Xanax (Alprazolam) Hydrocodone/ibuprofen taken with Xanax can result in additive drowsiness and respiratory depression. This can occur with any combination of opioid analgesics and benzodiazepine drugs. Flexeril and Lamictal can cause drowsiness. The ibuprofen part of hydrocodone/ibuprofen, added to lithium, can increase the risk of lithium toxicity causing weakness, tremor, thirst and confusion.
Indocin (Indomethacin) Lyrica (Pregabalin) Yes. Take Indocin with food or milk to avoid stomach upset. Take Lyrica at the same time each day.
Inhalers such as Symbicort and Pro-Air Phentermine Yes. They may be taken together. Follow instructions on the inhalers, and rinse your mouth after each Symbicort use.
Keflex (Cephalexin) Atarax (Hydroxyzine)  Yes. Take cephalexin until finished and hydroxyzine only as needed. Hydroxyzine can cause drowsiness.
Keflex (Cephalexin) Ciprofloxacin (Cipro) With ciprofloxacin and Keflex, you can go from one to the other without trouble. Taking them together would be duplication, but not harmful. Frequently doctors change antibiotic regimens when the response is unsatisfactory or the lab results indicate a better choice of drug. Take Cipro with food and until finished unless otherwise prescribed.
Keflex (Cephalexin) Colchicine Yes. They may be taken together if needed. Take Keflex until finished.
Keflex (Cephalexin) Echinacea Yes. There are no direct drug interactions between Echinacea and cephalexin (Keflex). 
Keflex (Cephalexin) Excedrin Yes. Take cephalexin until complete and Excedrin as needed.
Keflex (Cephalexin) Magnesium Citrate Oral Solution Yes. Take cephalexin until finished.
Keflex (Cephalexin) Percocet (Acetaminophen with Oxycodone) Yes. Take the antibiotic until completed and Percocet as needed. Percocet can cause drowsiness or an upset stomach.
Keflex (Cephalexin) Rynatan (Chlorpheniramine, Phenylephrine) Yes.
Keflex (Cephalexin) Vistaril (Hydroxyzine) Yes. Take the antibiotic until finished. Vistaril can cause drowsiness.
Levaquin (Levofloxacin) Amitriptyline (Elavil) and Metoprolol (Toprol, Lopressor) There is a possible interaction that can cause problems. The antibiotic Levaquin, when taken with amitriptyline, a tricyclic antidepressant, can increase the risk of a dangerous change in heartbeat or heart rhythm. You could have chest pain, dizziness, fainting or falling spells, palpitations, shortness of breath, or a change in your usual heart beat (fast, slow or irregular heart beat). Notify your health care provider immediately if any of these symptoms occur. Discuss alternative antibiotic therapy with your prescriber. Metoprolol has no interactions with the other two drugs.
Levaquin (Levofloxacin) Indomethacin (Indocin), Colchicine and Azithromycin (Zithromax) There are possible drug interactions. Levaquin taken with NSAIDs like indomethacin can increase the risk of seizures. Colchicine with azithromycin can cause an increase in the concentrations of colchicine. If you have problems with seizures, talk to your physician before taking Levaquin. The dose of colchicine may need to be adjusted while on azithromycin. Levaquin and azithromycin may be taken together, as their mechanisms of action are different.
Levaquin (Levofloxacin) Lunesta (Eszopiclone) Yes. Take the levofloxacin until finished. Lunesta, or any sleep aid, should only be taken if needed and in the smallest dose possible.
Levaquin (Levofloxacin) Percocet (Acetaminophen with Oxycodone) Yes. There are no direct drug interactions between these two. Limit the amount of acetaminophen from all sources to not more than 3000mg per day.
Levaquin (Levofloxacin) Phentermine (Adipex)  Yes. They may be taken together in the morning before breakfast.
Levaquin (Levofloxacin) Methocarbamol (Robaxin) Yes. The methocarbamol may cause drowsiness so be careful
if you must be alert. Take this only as prescribed, when needed.
Lexapro (Escitalopram) Alavert (Loratadine), Prilosec (Omeprazole) and Midol Yes. Take Lexapro and Prilosec at the same time every day and the others as needed. Avoid alcohol. Drink extra water, especially when taking Alavert and Midol.
Lexapro (Escitalopram) Amrix (Cyclobenzaprine) Amrix can increase the effects of serotonin, so it's advisable to be cautious about taking cyclobenzaprine and drugs that increase serotonin concentrations -- such as selective serotonin reuptake inhibitors (SSRIs-like Lexapro). This serotonin syndrome can cause confusion, tremors, tachycardia, delusions and hallucinations. Make sure all your physicians are aware of your medications, and notify them if you encounter any of these symptoms.
Lexapro (Escitalopram) Arginine and HMB for my workouts Yes. There are no direct drug interactions between Lexapro (escitalopram), arginine and HMB (beta-methylbutyrate). Talk with a dietitian or health trainer about taking more supplements for your workouts.
Lexapro (Escitalopram) Citalopram (Celexa) and Atenolol (Tenormin) There are no drug interactions between these three, but taking Lexapro and Celexa is duplication. They were developed and sold by the same company, and Lexapro is supposed to be an improvement over Celexa. Talk to your prescribing physician. Atenolol is not indicated for depression, but for high blood pressure or high heart rate. There are studies showing beta blockers (like atenolol) are effective for people with fears of crowds or public speaking.
Lexapro (Escitalopram) Cymbalta (Duloxetine), Lamictal (Lamotrigine) and Dilantin (Phenytoin) Concurrent use of Cymbalta and Lexapro could result in serotonin syndrome -- symptoms range from shivering and diarrhea to severe symptoms such as muscle rigidity, fever and seizures. Severe serotonin syndrome can be fatal if untreated. Concurrent use of Lexapro and Lamictal can result in increased risk of myoclonus -- sudden, involuntary jerking of a muscle or group of muscles. Restless leg syndrome is an example of myoclonus. Concurrent use of Dilantin and Lamictal can keep the Lamictal from working as well as intended. Talk with your physician.
Lexapro (Escitalopram) Methocarbamol (Robaxin) Yes. Take Lexapro at the same time each day and methocarbamol as needed. Methocarbamol can cause drowsiness.
Lexapro (Escitalopram) Midol (Acetaminophen with Pyrilamine) and Metformin (Glucophage)  Yes. Take Midol as needed. Take metformin at the same times daily before you eat. Do not stop Lexapro or alter your dosage without orders from your physician. Avoid alcohol. Have your blood sugar checked regularly.
Lexapro (Escitalopram) Tessalon (Benzonatate) Yes. Take the Lexapro as instructed by your physician and the Tessalon only as needed.
Lexapro (Escitalopram) Ultram (Tramadol) Concurrent use these drugs may result in an increased risk of seizures and serotonin syndrome (hypertension, hyperthermia, myoclonus, mental status changes). Talk with your doctors.
Lexapro (Escitalopram) Zantac (Ranitidine) Yes. Normally Lexapro is taken once daily in the morning. Zantac is normally prescribed once or twice daily, but can be given up to 4 times each day. Do not abruptly stop taking Lexapro. Take this every day, and follow the doctor's instructions.
Librax (Clidinium with Chlordiazepoxide) Anorex Yes. Librax can cause drowsiness.
Librax (Clidinium with Chlordiazepoxide) Antacids Yes. There are no drug interactions between Librax and the most common antacids (Maalox, Mylanta, Tums). Librax can cause drowsiness.
Librax (Clidinium with Chlordiazepoxide) Colace (Docusate) Yes. Colace will work more effectively if you drink plenty of water. Librax can cause drowsiness.
Librax (Clidinium with Chlordiazepoxide) Pantoprazole Yes. Both can cause drowsiness.
Librax (Clidinium with Chlordiazepoxide) Percocet (oxycodone w/acetaminophen) Although an interaction is possible, these drugs are sometimes used together. Do not drive or operate machinery until you know how these drugs affect you.
Lisinopril (Prinivil) Allegra D (Fexofenadine with Pseudoephedrine) Are you taking the lisinopril for your blood pressure? Did the same doctor prescribe both drugs? The pseudoephedrine in the Allegra D can increase blood pressure. If you are seeing multiple doctors, make sure everyone has a complete list of your medications and health issues. There are no direct drug interactions between lisinopril and Allegra D. Take lisinopril at the same time each day. Use Allegra as needed.
Lisinopril (Prinivil) Atenolol, Prilosec and Vicodin 5/500 Yes. Vicodin (hydrocodone with acetaminophen) can cause drowsiness and stomach upset. Limit the number per day to 8 or less. Even fewer if you take plain Tylenol in the same day. Take atenolol (Tenormin) and lisinopril at the same time each day.
Lisinopril (Prinivil) Celebrex (Celecoxib) Did the same doctor prescribe both? Concurrent use of NSAIDs and angiotensin converting enzyme (ACE) inhibitors can result in decreased antihypertensive and natriuretic effects. Talk to your doctor(s).
Lisinopril (Prinivil) Crestor (Rosuvastatin) Yes. Have your blood pressure checked regularly, and have an annual lipid panel drawn.
Lisinopril (Prinivil) Grapefruit Juice and Grapefruit Seed Extract Yes. Lisinopril does not interact with grapefruit juice or seed extract. You do not have to give up your grapefruit with lisinopril.
Lisinopril (Prinivil) Hydrochlorothiazide and Hydroxychloroquine Yes. There is a common, but mild side effect between lisinopril and hydrochlorothiazide. Taking ACE inhibitors (lisinopril) and thiazide diuretics (hydrochlorothiazide) can cause postural hypotension. These drugs are commonly used together to have an added effect on lowering blood pressure. Be careful when getting out of bed or out of a chair. Take hydroxychloroquine with food or milk.
Lisinopril (Prinivil) NyQuil If you have elevated blood pressure, avoid nasal decongestant, such as the pseudoephedrine in NyQuil formulas. Talk to your doctor. Fever-reducers, expectorants and antihistamines are fine, if you are only taking lisinopril. Do not stop taking lisinopril.
Lisinopril (Prinivil) Sudafed If you are taking medication for high blood pressure or heart problems, avoid decongestants unless otherwise instructed by your doctor. Oral decongestants constrict capillaries and blood vessels to reduce swelling. This increases blood pressure and the effort of the heart muscle. Talk to your physician if you have congestion. Use a saline nasal spray for minor nasal congestion.
Lisinopril (Prinivil) and Clonidine (Catapres) Tessalon (Benzonatate). I have seasonal allergies that come with a cough. My wife takes Tessalon and it seems to work. I would like to try it. I'm not sure if my high blood pressure medicine can be taken with it. Lisinopril does not interact with Tessalon. But there is a theoretically possible interaction between clonidine and Tessalon that can cause Central Nervous System depression (drowsiness, dizziness etc). Talk to your physician about adding Tessalon. Since it is a prescription medication, you would need your own prescription from your own physician in the proper dose for you.
Lisinopril/HCTZ 20-12.5 (Zestoretic, Prinzide) Meloxicam 15mg (Mobic), Pramipexole 0.5 mg (Mirapex), Clonazepam 1mg (Klonopin) and Venlafaxine 150mg (Effexor) There are a few possible interactions, but these drugs are often used together. Taking clonazepam and pramipexole together, you may feel drowsy or more tired. Do not drive or operate machinery until you know how these drugs affect you. Discuss any new or worsening side effects, like confusion or difficulty staying alert, with your health care provider. With lisinopril/HCTZ and meloxicam, nonsteroidal anti-inflammatory drugs (NSAIDs, such as Mobic) and drugs that reduce high blood pressure are often used together. Long-term use of NSAIDs may decrease the ability of antihypertensives to control your blood pressure, especially in older patients. If you take NSAIDs and antihypertensives together for long periods, your health care provider may monitor your blood pressure to make sure it is well-controlled. If you check your own blood pressure at home and notice an increase in your blood pressure, contact your health care provider. With meloxicam and venlafaxine, you might bruise or bleed more easily. Discuss any new or worsening side effects with your health care provider. Discuss your drug regimen with your health care provider prior to any surgeries or procedures. Make sure all of your health care providers have a current copy of your drug list.
Lithium Codeine Yes. Never stop taking lithium except with the advice and direction of the prescribing physician. Codeine may irritate your stomach and can cause drowsiness.
Lithium Fiber Tablets Yes, but there may be delayed absorption of the lithium, if it is taken with a large amount of fiber. Lithium should not be stopped unless instructed by the prescribing physician.
Lithium Herbal Remedies to Lose Weight No. It may be bad for your health. Have your physician recommend a dietitian and physical therapist to help you.
Lithium Cephalexin (Keflex) There are no direct drug interactions between cephalexin (Keflex) and lithium (Eskalith).
Lorazepam (Ativan) Fexofenadine (Allegra) Yes. They may be taken together if needed. You may have an increased chance of drowsiness.
Lorazepam (Ativan) Lunesta (Eszopiclone) Both are central nervous system depressant drugs. Taking them together has an additive effect. If both are prescribed by the same physician, be careful if you must be alert and never take more than prescribed. If they are not from the same doctor, inform all your health care providers about all the medications you take. Taking anything else that can cause central nervous system depression will increase these risks more. This includes some pain medications, alcohol, some blood pressure drugs, some antiparkinson's drugs and some antidepressants.
Lorazepam (Ativan) Midol Yes. Both can cause drowsiness.
Lorazepam (Ativan) Topamax (Topiramate) Although an interaction is possible, Topamax and lorazepam are often used together with close monitoring by physicians. You may feel drowsy or more tired when taking these drugs together. Do not drive or operate machinery until you know how these drugs affect you. If you experience a seizure or notice any new or worsening side effects such as confusion, difficulty staying alert, dizziness, abnormal eye movements, irritability, difficulty in walking, tremors or changes in mood, notify your health care provider.
Lyrica (Pregabalin) Atacand Plus (Candesartan with HCTZ) Yes.
Lyrica (Pregabalin) DayQuil and NyQuil Vicks DayQuil and NyQuil have many formulas. The typical one has acetaminophen, dextromethorphan, doxylamine and pseudoephedrine. Doxylamine is an antihistamine. Lyrica (pregabalin) has a slight risk of interaction with antihistamines. The result is higher incidence of drowsiness. Many nonprescription cough and cold products contain antihistamines; read labels carefully. Do not drive or operate machinery until you know how these drugs affect you. If you have heart disease or high blood pressure, talk to your doctor before taking any oral decongestant, like phenylephrine or pseudoephedrine.
Lyrica (Pregabalin) Zyloprim (Allopurinol) Yes. Drink plenty of fluids with the Zyloprim.
Maalox (Simethicone) Bactrim (Sulfamethoxazole with Trimethoprim) Drink plenty of water with the Bactrim, and finish the prescription. Take Maalox as needed, following the instructions on the bottle.
Maalox (Simethicone) Phenergan Although an interaction is possible, these drugs are often used together. Take Phenergan at least 1 hour before or 2 hours after you take the antacids.
Masteron (Drostanolone Propionate) A Beta Blocker Masteron is a non-approved anabolic steroid used by body builders, weight-lifters and sports teams. It is a breakdown product of testosterone. It is not approved for use in the United States. Any steroid product related to testosterone can decrease the effectiveness of beta blockers (metoprolol, propranolol, sotalol, nadolol). Check your blood pressure regularly and if you notice an increase, talk to your doctor.
Medrol (Methylprednisolone) Benzonatate (Tessalon) and Levaquin (Levofloxacin) You can take benzonatate with Medrol and Levaquin. There may be a problem with Levaquin and Medrol. In some -- I assume it may be athletes -- concurrent use of the class of antibiotics like Levaquin and the steroids like Medrol, can increase the risk for tendon rupture. If the same doctor prescribed both, he or she may not feel there is much risk and the benefit of taking both outweighs the chance of having a problem. If you are an athlete, work out a lot or do strenuous work, talk to your doctor.
Medrol (Methylprednisolone) Hydroxyzine Yes. Take Medrol with food or milk and until finished. Hydroxyzine can cause drowsiness, sometimes extreme. Take only as needed.
Medrol (Methylprednisolone) Klonopin (Clonazepam) Yes. Take Medrol with food or milk to avoid stomach upset and take as long as prescribed. Clonazepam can cause drowsiness.
Medrol (Methylprednisolone) Neurontin (Gabapentin) Yes. They may be taken together if needed. To prevent stomach upset, take Medrol with food or milk until the package is done. Take Neurontin as prescribed.
Melatonin Xanax (Alprazolam) No. Talk to your doctor. Generally it is recommended that you do not take two drugs for sleep, nervousness or anxiety together. You may feel drowsy when taking these drugs. Do not drive or operate machinery until you know how these drugs affect you.
Meridia (Sibutramine) Lexapro (Escitalopram) There is a possible problem. In general, you should not take Merida and selective serotonin reuptake inhibitors (SSRIs). Examples of SSRIs include Celexa, Lexapro, Luvox, Paxil, Prozac, Sarafem and Zoloft. The combination could increase the risk of confusion, increased blood pressure or heart rate, loss of coordination, restlessness, sweating, tremor, vomiting or other serious side effects.
Metformin (Glucophage) Celebrex Yes. Both should be taken with food.
Metformin (Glucophage) Donnatal Yes. Follow you physician's dosing instructions. Donnatal can cause drowsiness and dry you out. Drink plenty of fluids. Take metformin with food.
Metformin (Glucophage) Excedrin Migraine Yes. Take Excedrin as needed. Limit acetaminophen (Tylenol) intake to 3000mg daily. Metformin is normally taken twice daily with food. Monitor your blood sugars.
Metformin (Glucophage) l-Thyroxine (Synthroid), Lovastatin (Mevacor), Diltiazem (Cardizem), Lexapro and Hydroxychloroquine There are two potential drug interactions. One involves your current therapy. Taking diltiazem and lovastatin together may increase the risk of myopathy or rhabdomyolysis -- muscle conditions that statin drugs are linked with that can cause weakness and pain. If you notice these symptoms, contact the prescribing physician as soon as possible. The other interaction involves metformin and l-thyroxine. Taking these together may decrease the effectiveness of the metformin. Take the l-thyroxine 30 minutes before breakfast. Normally metformin is taken twice daily with meals -- usually with breakfast and dinner. Is the same physician prescribing all your drugs? Did your doctor discuss how and when to take your medications? Any new prescription should be explained completely by the doctor. The route, time, length of time to take and side effects should be totally understood by the patient before leaving the doctor and pharmacy.
Methimazole (Tapazole) Protonix (Pantoprazole) Yes.
Methocarbamol (Robaxin) Advil (Ibuprofen) Yes. Take Advil with food or milk. Methocarbamol can cause drowsiness. Take these as needed.
Methocarbamol (Robaxin) Diclofenac/Voltaren Yes. Methocarbamol can cause drowsiness. Take Voltaren with food or drink. Avoid alcohol with methocarbamol.
Methocarbamol (Robaxin) Indocin (Indomethacin) Yes. Take Indocin with food. Avoid aspirin while taking Indocin. Methocarbamol can cause drowsiness. Take only as long as needed.
Methocarbamol (Robaxin) Meloxicam (Mobic) Yes. Take meloxicam with food or milk. Methocarbamol can cause drowsiness.
Methocarbamol (Robaxin) Prilosec (omeprazole) There are no direct drug interactions between methocarbamol (Robaxin) and Prilosec (omeprazole). These may be taken together.
Methocarbamol (Robaxin) Ultram (Tramadol) Yes. These drugs are frequently used together, one a muscle relaxant and the other a pain reliever. Both can cause drowsiness. Avoid alcohol. Take as needed.
Methocarbamol (Robaxin) Valium (Diazepam) There is a potentially serious drug interaction -- taking Valium (or any benzodiazepine) with a centrally acting muscle relaxant (like methocarbamol) can produce additive respiratory depression. You could stop breathing. I have seen these prescribed together in patients with severe muscle problems, so it is not completely unusual. I hope both were prescribed by one physician who is monitoring you closely. If you have ever had breathing problems or asthma, tell your doctor. Adding any other product that can slow you down or make you drowsy (especially alcohol or narcotic pain relievers) could make this worse. Notify your doctor if you have difficulty breathing.
Methocarbamol (Robaxin) Wellbutrin (Bupropion) Yes. Be careful if you are beginning either of these drugs, and inform your physician of any changes in how you feel. Methocarbamol can cause drowsiness. Wellbutrin can cause agitation. Take methocarbamol as needed for muscle relaxation and Wellbutrin regularly every day. Avoid alcohol.
Methylprednisolone (Medrol) Norvasc (Amlodipine), Crestor (Rosuvastatin) and Low-Dose Aspirin Norvasc and Crestor are fine with methylprednisolone, but there could be an interaction with the low-dose aspirin. And although an interaction is possible, these drugs may be used together for short periods of time. Side effects from aspirin (stomach upset, nausea or heartburn) could get worse or more serious. Side effects such as ulcers may occur if you also take a steroid like methylprednisolone.  Take methylprednisolone with food or milk.
Metoprolol (Toprol, Lopressor) Citalopram (Celexa) Did the same doctor prescribe both? Were you taking citalopram before starting Toprol? Celexa, an SSRI, can increase the expected action of metoprolol. This may result in increased metoprolol plasma concentrations and possible loss of metoprolol cardioselectivity. If you were taking Toprol first, adding Celexa could increase the metoprolol adding to side effects of the beta blocker. Talk to the doctor(s) who prescribed these.
Metoprolol (Toprol, Lopressor) Imodium (Loperamide) Yes. Take metoprolol at the same time daily. Take Imodium as needed.
Metoprolol (Toprol, Lopressor) Losartan (Cozaar) Both losartan (Cozaar) and Toprol (metoprolol) are normally used for high blood pressure. Although an interaction is possible, these drugs may be used together. While taking these medications, you may become dizzy or feel faint.
Metoprolol (Toprol, Lopressor) Theophylline (Slo-Bid, Theo-Dur)
You should inform all your health care providers of your list of medications. Toprol (metoprolol succinate) is a beta blocker. There are some beta blockers that do cause a chance of interaction with theophylline. Toprol has not been shown to do this. I still would make sure both physicians are aware of the drugs you have been prescribed. These drugs are important for your conditions. If you take these both, notify your doctors if you notice breathing changes.
Metronidazole (Flagyl) Phentermine (Adipex) Yes. Take metronidazole until finished with food or milk. If you have high blood pressure or heart problems, talk to your doctor before using phentermine, as this can increase heart rate or raise blood pressure.
Metronidazole (Flagyl) Metoprolol (Lopressor or Toprol) and Lisinopril-HCTZ (Zestoretic or Prinzide) Yes. Take metronidazole with food. Avoid alcohol.  Take the antibiotic until it is gone.
Micardis (Telmisartan) Advil, Tylenol and Pepcid AC When Needed
One interaction between Micardis and Advil (ibuprofen) -- actually any angiotensin II receptor blocker and NSAID -- is decreased effectiveness of Micardis and possible renal impairment. These problems are quite rare, but I'd suggest you use Tylenol (acetaminophen) instead of Advil. Pepcid (famotidine) is fine with any of these. Take Micardis at the same time each day.
Micardis (Telmisartan) Plus Valium (Diazepam), Plaquenil (Hydroxychloroquine)and Pristiq (Desvenlafaxine) By Micardis Plus, I assume you mean Micardis HCT (telmisartan with hydrochlorothiazide). Yes. You can take these together. Always take Plaquenil with food. Valium can cause drowsiness.
Micardis HCT (Telmisartan with hctz) Aleve (Naproxen) or Tylenol (Acetaminophen) There is an interaction between Micardis HCT and Aleve. Taking NSAIDs (Aleve) with thiazide diuretics (hctz) and angiotensin II receptor blockers (telmisartan) can result in decreased diuretic and antihypertensive efficacy and an increased risk of renal impairment -- meaning your blood pressure may not be controlled and you may still retain fluids -- possibly to the point of kidney problems. Tylenol is fine to use with Micardis HCT. Talk to your doctor about Aleve. Limit Tylenol to no more than 3000mg per day. Take Micardis HCT at the same time each day.
Midol Cortisone or Methylprednisolone Yes. If you are taking cortisone or methylprednisolone orally, do not take other steroid or NSAIDs (nonsteroidal anti-inflammatory drugs) at the same time. Take these with food to prevent stomach upset.
Midol Keflex (Cephalexin) Yes. Take cephalexin until gone and Midol as needed. Avoid alcohol while taking Midol.
Miralax Amitiza (Lubiprostone) Yes. Miralax works by helping retain fluid in the GI tract. Amitiza helps pull fluid through the wall of the GI tract to soften the stool. The two would help together through different means.
Mirapex (Pramipexole) A Pain Killer There are no direct drug interactions between Mirapex and the common pain relievers.  If you take a narcotic or any pain medication that can cause drowsiness, Mirapex can intensify the sedative effect.
Mobic (Meloxicam) Adderall Yes. Mobic is an NSAID, so take it with food or milk to protect the stomach. Take Adderall regularly at the same times each day. Plan ahead for refilling this drug as it may take extra time to get the prescription due to DEA restrictions.
Mobic (Meloxicam) Advil PM (Ibuprofen with Diphenhydramine) No drug interactions, but they are NSAIDs and a duplication of therapy. If you are taking Advil PM  to help you sleep, consider plain diphenhydramine (Benadryl) instead. Always take NSAIDs with food or milk to avoid stomach upset.
Mobic (Meloxicam) Ambien (Zolpidem) Yes. Take Ambien just prior to bedtime, if needed for sleep. Mobic is an NSAID, so take it with food or milk to avoid stomach upset. Take both only as needed.
Mobic (Meloxicam) Ambien CR Yes. Take Ambien at bedtime, if needed for sleep. Mobic is an NSAID, so take it with food or milk to avoid stomach upset. Take both as needed.
Mobic (Meloxicam) Armour Thyroid (desiccated thyroid) There are no direct drug interactions between Mobic (meloxicam) and Armour Thyroid (desiccated thyroid). Thyroid products should be taken on an empty stomach, early in the day. I would recommend not taking these at the same time. Leave a couple of hours between doses of these.
Mobic (Meloxicam) Azithromycin (Zithromax) Yes.
Mobic (Meloxicam) Flecainide (Tambocor) Yes.
Mobic (Meloxicam) Flexeril Yes. They are frequently prescribed together. Flexeril is a muscle relaxer, and Mobic is an NSAID, nonsteroidal anti-inflammatory pain reliever. Take Mobic with food or milk. Flexeril can cause drowsiness. Take these only as needed.
Mobic (Meloxicam) Hydrocodone with acetaminophen (Norco, Vicodin, Lorcet or Lortab) Yes. Take this if needed and be careful if you must be alert.
Mobic (Meloxicam) Penicillin Yes. Take the penicillin until finished and the Mobic with food when needed.
Mobic (Meloxicam) Toprol or Lopressor(Metoprolol) There can be a minor interaction. If you were taking the metoprolol before starting the meloxicam, the control of your blood pressure could be reduced. NSAIDs and beta blockers taken together can have a reduction of antihypertensive effect. Get your blood pressure checked regularly. Take meloxicam only as needed.
Mobic (Meloxicam) Ultram (Tramadol) Yes. Mobic is an NSAID, so take it with food or milk. Take Ultram as needed for pain. Ultram can cause drowsiness. Avoid alcohol.
Mylanta (Simethicone) Ampicillin Yes, but do not take them at the same time. Take them an hour apart.
Mylanta (Simethicone) Protonix (Pantoprazole) Yes. Protonix and Mylanta work differently. Protonix keeps acid from forming, and Mylanta breaks up the gas bubbles once they are made.
Naproxen (Naprosyn, Aleve) Ambien (Zolpidem) Yes. Take naproxen with food or milk to avoid stomach upset. Take Ambien only if you can devote eight hours for sleep. Take both as needed.
Naproxen (Naprosyn, Aleve) Amrix (Cyclobenzaprine) Yes. Take naproxen with food or milk. As a muscle relaxant, Amrix can cause drowsiness. Take these as needed.
Naproxen (Naprosyn, Aleve) Benicar (Olmesartan) No. Concurrent use of Angiotensin II receptor blockers (Benicar) and nonsteroidal anti-inflammatory agents (NSAIDs/Aleve) may result in decreased antihypertensive effects and an increased risk of renal impairment. Aleve may decrease the effectiveness of the Benicar and could cause a kidney problem. Take Tylenol (acetaminophen) instead of Aleve. Do not stop the Benicar unless your physician tells you.
Naproxen (Naprosyn, Aleve) Cipro (Ciprofloxacin) There is a possible side effect that can occur at high doses. Taking a Quinolone antibiotic -- like Cipro -- with nonsteroidal anti-inflammatory drugs (NSAIDs) -- like naproxen -- can make it easier for you to have a seizure. If you have had seizures, or take these and do have a seizure, call your doctor immediately. This is rare and happens at high doses. Take Cipro until finished and naproxen as needed, with food. An alternative to the NSAID is aspirin. There are no problems with aspirin and Cipro. Use aspirin only if you do not have bleeding problems in the digestive tract.
Naproxen (Naprosyn, Aleve) Diflucan (Fluconazole) Yes. Both can cause nausea and stomach upset, so take them with food.
Naproxen (Naprosyn, Aleve) Doxepin Hydrochloride (Sinequan) Yes. Take naproxen with food or milk and only as needed. Doxepin can cause drowsiness.
Naproxen (Naprosyn, Aleve) Erythromycin and Fexofenadine Hydrochloride (Allegra) There is a possible interaction between erythromycin and fexofenadine, but therapeutically it appears not to be problematic. When taking erythromycin, the blood levels of the fexofenadine are increased. In theory, then, the side effects of the antihistamine may increase. Be careful if you must be alert, as drowsiness is the most common side effect. There are no interactions with naproxen and the other two, but both naproxen and erythromycin irritate the stomach, so take both with food or milk. Take erythromycin until finished.
Naproxen (Naprosyn, Aleve) Lisinopril, Lexapro (Escitalopram) and Metformin There are two problems with these medications and they both involve Aleve. Aleve is an NSAID (nonsteroidal anti-inflammatory drug). Concurrent use of SSRIs (Lexapro) and NSAIDs may result in an increased risk of bleeding. Further, concurrent use of angiotensin converting enzyme inhibitors (like lisinopril) and NSAIDS may result in decreased antihypertensive and natriuretic effects. Inform all your doctors of your full medication list.
Naproxen (Naprosyn, Aleve) Metformin (Glucophage) Yes. Take metformin as prescribed by the physician. Alway take Aleve with food or milk to protect the stomach. Take only as needed.
Naproxen (Naprosyn, Aleve) Oxycodone with APAP (Percocet) Yes. Take both as needed, with food or milk to prevent stomach upset. Limit Percocet to a maximum of 3000mg acetaminophen in 24 hours. Check the label to see how much is in your tablets. Percocet can cause drowsiness.
Naproxen (Naprosyn, Aleve) Pepcid (Famotidine) and Clindamycin (Cleocin) Yes. Take naproxen with food or milk to protect your stomach. Take the clindamycin as directed by your physician and until finished.
Naproxen (Naprosyn, Aleve) Pseudoephedrine, or Generic Cold and Sinus Medications Yes. There are no direct drug interactions between naproxen, pseudoephedrine (Sudafed) and acetaminophen (Tylenol), which is in most cold/sinus medications. Take naproxen with food or milk. If you have high blood pressure or heart problems, talk to your doctor before taking pseudoephedrine.
Naproxen (Naprosyn, Aleve) Soma and a Multivitamin Yes. Take naproxen (Naprosyn, Aleve) with food or milk. As a muscle relaxant, Soma can cause drowsiness.
Naproxen (Naprosyn, Aleve) Zyrtec Yes. Always take naproxen or any NSAID (nonsteroidal anti-inflammatory drug) with food or milk to protect the stomach.
Naproxen (Naprosyn, Aleve) Zyrtec D Yes. They may be taken together. Take naproxen as needed and with food or milk. If you have high blood pressure or heart problems, talk to your doctor before to taking Zyrtec D. Drink plenty of water when taking Zyrtec.
Naproxen (Anaprox, Naprosyn) Hyoscyamine (Levsin) Yes. The naproxen can upset the stomach so take it with food or milk.
Naproxen (Anaprox, Naprosyn) Valtrex (Valacyclovir) Yes. Take the naproxen with food or milk to prevent stomach upset.
Nexium (Esomeprazole) Benicar (Olmesartan), Lexapro (Escitalopram), Atenolol (Tenormin) and VESIcare (Solifenacin) Taking Nexium with VESIcare may cause the Nexium not to be as effective. If you have stomach or GI problems, this may be the reason. Talk to your physician. Taking Nexium with Lexapro can cause an increase in Lexapro side effects: confusion, dizziness, drowsiness and dry mouth. Contact your doctor if you notice these symptoms. Another issue is the blood pressure medications. These are commonly used together, but some notice dizziness and faint feelings, due to lowering of the blood pressure. If this occurs and doesn't go away in a few days, contact your physician. If you have just started these two, be careful getting up from a chair or out of bed. 
Norco 10/325 (Hydrocodone with Acetaminophen) ProAir (Albuterol) Yes. Use these as needed and if you must be alert, the Norco may make you drowsy.
Norco 10/325 (Hydrocodone with Acetaminophen) Excedrin Migraine (Aspirin, Acetaminophen, and Caffeine)
No. Both contain acetaminophen. Taking both can increase the risk of kidney side effects. Immediately tell your doctor if you get pain while going to the bathroom, stomach pain, blood in your urine (pink color) or problems starting your urine stream. Limit the daily amount of acetaminophen (Tylenol) to 3000mg.
Norvasc (Amlodipine) Benicar HCT and Cheratussin AC Yes. Only take the Cheratussin AC (guaifenesin with codeine) if it is prescribed for you and then only as needed. Avoid grapefruit when taking amlodipine.
Novocaine Coreg Yes. Normally the Coreg is given twice daily to lower blood pressure or control a heart condition. Coreg can cause drowsiness, dizziness, hypotension and erectile dysfunction in men. Do not stop taking the Coreg abruptly, and take the doses at the same time each day.
NyQuil (Acetaminophen, Dextromethorphan, Doxylamine and Pseudoephedrine) Actifed (chlorpheniramine with phenylephrine) These both contain antihistamines and decongestants. Do not take these together without talking to your prescriber. If you have high blood pressure or heart disease, you should avoid oral decongestants. Taking pseudoephedrine or phenylephrine can increase the risk of high blood pressure, nervousness, palpitations, problems with sleep, or other serious side effects.
NyQuil (Acetaminophen, Dextromethorphan, Doxylamine and Pseudoephedrine) Adderall Avoid alcohol with Adderall. NyQuil contains a fairly high concentration of alcohol, as well as antihistamines and decongestants. Talk with your doctor before taking these together.
NyQuil (Acetaminophen, Dextromethorphan, Doxylamine and Pseudoephedrine) Allegra D (Fexofenadine with Pseudoephedrine) Take one or the other, not both. You would be duplicating some ingredients with both of these. Allegra D is a long-acting, lower sedating antihistamine/decongestant. Vicks NyQuil has acetaminophen/dextromethorphan/doxylamine/pseudoephedrine. The liquid form also contains a high percentage of alcohol. Drink plenty of water when taking either one of these medications.
NyQuil (Acetaminophen, Dextromethorphan, Doxylamine and Pseudoephedrine) Benzonatate (Tessalon) Yes, however, I would suggest you avoid Nyquil, or any cold product with a decongestant if you have heart disease or high blood pressure.  The decongestants can constrict your blood vessels putting strain on your heart and raising blood pressure.
NyQuil (Acetaminophen, Dextromethorphan, Doxylamine and Pseudoephedrine) Claritin (Loratadine) I would not recommend this, as Nyquil contains an antihistamine and the Claritin (loratadine) is an antihistamine. This is a duplication of therapy. Although an interaction is possible, these drugs are often used together. You may feel drowsy or more tired when taking these drugs together.
NyQuil (Acetaminophen, Dextromethorphan, Doxylamine and Pseudoephedrine) Indomethacin (Indocin) Yes. Take indomethacin with food or milk. Take Nyquil at bedtime only. Talk to your doctor before taking Nyquil if you have high blood pressure or heart problems.
NyQuil (Acetaminophen, Dextromethorphan, Doxylamine and Pseudoephedrine) Lamictal  (Lamotrigine) and Wellbutrin (Bupropion) No. Major interactions with both of these can occur if you take NyQuil, including nervousness, irritability, difficulty sleeping, increased blood pressure, seizures or other effects. Talk to your doctors.
NyQuil (Acetaminophen, Dextromethorphan, Doxylamine and Pseudoephedrine) Levaquin (Levofloxacin) Yes. Take the antibiotic early each day until gone. NyQuil can cause drowsiness. Take only as needed.
NyQuil (Acetaminophen, Dextromethorphan, Doxylamine and Pseudoephedrine) Lisinopril (Prinivil), Hydrochlorothiazide (HCTZ), Verapamil (Calan) and Citalopram (Celexa) You should avoid the decongestant (pseudoephedrine) in NyQuil, which can constrict blood vessels causing increased blood pressure and strain on your heart. Further, there is a potential problem with postural hypotension. Lisinopril, verapamil and hydrochlorothiazide are for your heart and blood pressure. Vicks NyQuil and citalopram can cause drowsiness. When you first get up from bed or sitting a while, there is a chance to lose your balance and fall. If you must be alert, be careful. Talk to your doctor before taking any more decongestants.
NyQuil (Acetaminophen, Dextromethorphan, Doxylamine and Pseudoephedrine) Lorazepam (Ativan) There is an interaction. Lorazepam taken with the Vicks Nyquil will cause a greater chance for drowsiness. If you must take these two together, be careful if you must be alert.
NyQuil (Acetaminophen, Dextromethorphan, Doxylamine and Pseudoephedrine) Lortab (Hydrocodone with Acetaminophen) There is a possible interaction between Lortab (hydrocodone with acetaminophen) and Vicks Nyquil (acetaminophen, dextromethorphan, doxylamine, pseudoephedrine). The antihistamine in the Nyquil and the pain reliever both can cause drowsiness. Both products also contain acetaminophen (Tylenol). You have to be careful not to exceed 3000mg in 24 hours of all forms of acetaminophen.
NyQuil (Acetaminophen, Dextromethorphan, Doxylamine and Pseudoephedrine) Mobic (Meloxicam) and Ultram (Tramadol) Yes. All can cause drowsiness. Take only as needed.
NyQuil (Acetaminophen, Dextromethorphan, Doxylamine and Pseudoephedrine) Multivitamin, Probiotic and Chantix I used Centrum multiple vitamins and the probiotic lactobacillus with Chantix (varenicline) and Vicks Nyquil for the interaction research and found no direct drug interactions with these. If you have heart disease or high blood pressure, reconsider using any product with a decongestant, as it can increase blood pressure. Good luck with the smoking cessation.
NyQuil (Acetaminophen, Dextromethorphan, Doxylamine and Pseudoephedrine) Nasal Decongestant (Phenylephrine HCL) If you do not have high blood pressure or heart problems, and you have symptoms that require all these medications, then it should be OK. Some formulations of Vicks NyQuil contain a nasal decongestant, so be certain that your bottle does not. NyQuil can cause drowsiness. Take these only as needed.
NyQuil (Acetaminophen, Dextromethorphan, Doxylamine and Pseudoephedrine) Suphedrine PE (Phenylephrine) Yes, but there is a duplication of similar decongestants -- Nyquil uses pseudoephedrine. If you have heart or blood pressure problems, talk to your physician before taking more of either of these medications.
NyQuil (Acetaminophen, Dextromethorphan, Doxylamine and Pseudoephedrine) Tussionex  The only real drug interactions involve duplication of therapy and additive side effects. Vicks NyQuil has a cough suppressant, dextromethorphan and the antihistamine doxylamine. Tussionex is a time-release narcotic antitussive, hydrocodone with the antihistamine chlorpheniramine. You should not need both products in the same 12-hour period. The drowsiness you could experience would impair judgments and abilities. Take one or the other, not both.
NyQuil (Acetaminophen, Dextromethorphan, Doxylamine and Pseudoephedrine) Ultram (Tramadol) Both cause drowsiness, so you may feel drowsy or more tired when taking these together. Many nonprescription cough and cold products contain anti-histamines. Carefully read labels before taking any medicine with Ultram or any other sedating pain medication. Take both only as needed. Be careful if you must be alert.
NyQuil (Acetaminophen, Dextromethorphan, Doxylamine and Pseudoephedrine) Unisom There is no reason to take both -- they both contain the antihistamine doxylamine. If you are trying to sleep, Unisom is all you need.  Diphenhydramine is most likely less expensive and just as effective.
If you have cold symptoms, then Vicks NyQuil would take care of any common cold problem. If you have high blood pressure or heart problems, avoid NyQuil as the pseudoephedrine can cause problems.
NyQuil (Acetaminophen, Dextromethorphan, Doxylamine and Pseudoephedrine) Venlafaxine HCL (Effexor) No. Venlafaxine is an SSRI (selective serotonin reuptake inhibitors). Do not take dextromethorphan with ANY SSRI without talking to your health care provider. Side effects may get worse if you take these drugs together. This combination may increase the risk of confusion, increased blood pressure or heart rate, loss of coordination, restlessness, sweating, tremor, vomiting or other serious side effects.  Do not exceed recommended doses of cough products containing dextromethorphan. Report any troublesome effects that occur. Many nonprescription cough products contain dextromethorphan. Read labels carefully. Make sure all your health care providers have a current list of the drugs you take.
NyQuil (Acetaminophen, Dextromethorphan, Doxylamine and Pseudoephedrine) Zyrtec (Cetirizine) Do not take Zyrtec and other antihistamines together without talking to your doctor. This may is a duplicate therapy, as both agents are antihistamines. You may feel drowsy or more tired when taking these drugs together. You may experience side effects: constipation, dizziness, difficulty with urination, dry mouth and eyes, changes in vision, fast heartbeat or confusion. Because Zyrtec is a long-acting antihistamine, the effects can last up to 24 hours.  If your only issue is the nasal drip, NyQuil contains medications you do not need. The pseudoephedrine in Nyquil can actually cause your sinuses to drain more. You may want to try using a moderate action antihistamine like Allegra (fexofenadine). Take the 30mg or 6omg tablets up to twice daily for allergies. This way you don't take more drugs than you need.
NyQuil Gel Tabs for Cough and Cold ProAir HFA Inhaler Yes. Take NyQuil as needed, and always keep the ProAir with you to stop an asthma attack. If you have -- or take care of someone with -- asthma, learn all you can about this condition. Find out what the triggers are, and remove them from your environment. There are many places to find support, and get answers and helpful tips about asthma.
Nytol St. Johns Wort Yes. Take Nytol only as needed at bedtime. 
Oxycodone (OxyContin) Hydroxyzine HCL (Atarax) The interaction is due to their common side effect, drowsiness, which could be extreme. This effect may last for a few days after you stop taking these drugs together. Do not drive or operate machinery until you know how these drugs affect you. If you notice slurred speech, confusion, severe weakness or difficulty breathing, contact your doctor immediately. Take these medications only as directed and only as needed. Never take more than prescribed.
Oxycodone (OxyContin) Methylprednisolone (Medrol) Yes. Take with food or milk to prevent stomach upset. Take the methylprednisolone as prescribed and the oxycodone only when needed.
Pamprin (Acetaminophen, Pamabrom and Pyrilamine) HCTZ (Hydrochlorothiazide) Yes. They may be taken together. Take Pamprin only as needed.
Pantoprazole Sod (Protonix) Mylanta Ultimate (Aluminum and Magnesium Hydroxides) Yes, but not at the same time. Mylanta works by coating the esophagus and stomach. Take pantoprazole at least 30 minutes before any meal or dose of Mylanta. Tell your pharmacist that you use Mylanta frequently, as this can affect many medications.
Paracetamol (Acetaminophen/Tylenol) Mesalazine (Mesalamine/Asacol) Yes. These brands are not available in the United States, but there are no direct drug interactions between Paracetamol and mesalazine. They may be taken together.
Paxil (Paroxetine) Adipex (Phentermine) Do not take Paxil and Adipex together without talking to all of your physicians. Adipex and selective serotonin reuptake inhibitors (also known as SSRIs), like Paxil, should not be taken together. Side effects from the SSRIs may get worse if you also take phentermine.  This combination may increase the risk of confusion, increased blood pressure or heart rate, loss of coordination, restlessness, sweating, tremor, vomiting, or other serious side effects.
Paxil (Paroxetine) CVS Allergy Relief (Cetirizine Hydrochloride) Yes. There are no direct drug interactions between Paxil and cetirizine (Zyrtec). They may be taken together. Both can cause drowsiness.
Paxil (Paroxetine) Over the Counter Cough Medicine The most common OTC cough syrup is dextromethorphan. If you take it with Paxil, there could be issues, mostly due to Paxil's side effects. Although an interaction is possible, these drugs may be used together with caution, and are often used together for brief periods. Side effects from Paxil may get worse: increased risk of restlessness, sweating, tremor, vomiting or other side effects. Do not exceed recommended doses of cough products containing dextromethorphan, and report any troublesome effects that occur. Many nonprescription cough products contain dextromethorphan. Read labels carefully before taking any product with Paxil.
Paxil CR (Paroxetine) Lisinopril (Zestril, Prinivil), Hydrochlorothiazide (HCTZ)and Iron Sulfate Tablets Yes. They may be taken together if needed. I suggest taking the iron sulfate tablets with food to avoid stomach irritation.
Pepcid (Famotidine) Fexofenadine (Allegra) Yes. Normally the Prevacid is taken with the largest meal of the day.
Pepcid (Famotidine) Maalox (Aluminum, Magnesium Hydroxides and Simethicone) Yes. These work differently, and the benefits can be additive. You may want to try Pepcid Complete, which is a similar product (without the anti-gas simethicone) all in one.
Pepcid (Famotidine) Motrin (Ibuprofen) and Lipitor (Atorvastatin) Yes. Take Motrin with food or milk to protect the stomach. If you are taking Pepcid for ulcers, consider taking Tylenol (acetaminophen), which is easier on the GI system.
Peptac (Calcium Carbonate, Sodium Bicarbonate and Sodium Alginate) Methotrexate Peptac is a British drug not available in the United States. There are no direct interactions with methotrexate and Peptac. I also researched the drug Pepcid (famotidine) in case there was a misspelling. There are no direct drug interactions with this and methotrexate either. Be sure to follow the physician instructions with the powerful medication methotrexate.
Phentermine (Adipex) Adderall These medications have similar side effects. Adipex can cause hypertension, weight loss, abdominal pain, dry mouth, appetite loss, sleeplessness, headache and feeling nervous. Adderall can cause increased blood pressure, palpitations, tachyarrhythmia, hives, bad mouth taste, constipation, diarrhea, dry mouth, gastrointestinal disturbance, decreased mental alertness, dizziness, euphoria, excitement, decrease of functional performance/activity, depressed mood, impotence, tremor, headache, sleeplessness, restlessness, libido changes. Your doctor and pharmacy should have explained the side effects. If you have high blood pressure or heart problems, talk to your doctor before taking these medications.
Phentermine (Adipex) Acai Berry I could not find any study with the combination phentermine and acai berry. Acai berry is considered a food supplement not subject to FDA drug scrutiny. There may be some problems with acai berry by itself if you have other underlying conditions. It’s possible that acai may trigger or worsen swelling, high blood pressure, ulcers or intestinal bleeding. If you take any medicines regularly, talk to your doctor before you start using acai supplements. They could interact with over-the-counter medicines like ibuprofen and other NSAID painkillers, as well as prescription medicines for pain. Don’t take acai if you’re taking cancer drugs, as it could block their effectiveness. Don’t use acai with other antioxidant supplements without your doctor’s approval.
Phentermine (Adipex) Amitiza (Lubiprostone) Yes, but I would be hesitant to take phentermine if I had any type of irritable bowel syndrome. Phentermine is a stimulant similar to amphetamine that could have an effect on your condition. Talk to your physician.
Phentermine (Adipex) Amphetamine No. You should not take phentermine with any amphetamine or amphetamine-like product (Adderal, Ritalin, Concerta). Taking these together provides no added benefit and can increase the risk of high blood pressure, nervousness, palpitations, sleep problems or other serious side effects.
Phentermine (Adipex) Benicar (Olmesartan) Drug interactions -- no, but phentermine can cause your blood pressure to increase, and that is inappropriate for a person who already has high blood pressure.
Phentermine (Adipex) Benzonatate (Tessalon) Yes. Take phentermine in the morning and benzonatate only as needed for cough. Benzonatate can cause drowsiness.
Phentermine (Adipex) Celexa (citalopram) Phentermine (Adipex) and selective serotonin reuptake inhibitors (also known as SSRIs) like citalopram (Celexa) should not be taken together. Side effects such as confusion, drowsiness, increased heart rate, loss of coordination, restlessness, sweating, tremors, or vomiting may occur if you take these medicines together.
Phentermine (Adipex) DayQuil or NyQuil I would not take phentermine with either of these cold medications, or any that have a decongestant. Both Vicks DayQuil and Vicks NyQuil have pseudoephedrine. Taking pseudoephedrine with the phentermine, or any stimulant drug, can increase the risk of high blood pressure, nervousness, palpitations, sleep problems or other serious side effects. Talk to your physician before taking phentermine if you have any heart or blood pressure issues.
Phentermine (Adipex) Diclofenac (Voltaren) Yes. If you have high blood pressure or heart problems, talk with your doctor before taking Adipex. Take diclofenac with food or milk.
Phentermine (Adipex) Effexor XR (Venlafaxine) No. It is NOT recommended to take Effexor with any weight loss medications like Adipex. Effexor has a "Black Box" warning:"Antidepressants increased the risk of suicidal thinking and behavior in children, adolescents and young adults in short-term studies with major depressive disorder (MDD) and other psychiatric disorders. Short-term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults beyond 24, and there was a reduction in risk with antidepressants compared to placebo in adults 65 and older. This risk must be balanced with the clinical need. Monitor patients closely for clinical worsening, suicidality or unusual changes in behavior. Families and caregivers should be advised of the need for close observation and communication with the prescriber. Not approved for use in pediatric patients. Concomitant use with weight loss agents (phentermine); concurrent use not recommended."

Phentermine can cause elevated blood pressure, decreased mental alertness, dizziness, palpitations and tachyarrhythmia. When taking Effexor, do not abruptly stop taking it. Patients need to be taken off these types of medications in a controlled decreasing dose regimen.
Phentermine (Adipex) Excedrin (Acetaminophen, Aspirin, Caffeine) I would recommend plain Tylenol or aspirin for headaches. The problem with phentermine and Excedrin is that both are stimulants.  This can cause extreme jitteriness and nervousness, and strain on the heart.
Phentermine (Adipex) Librax Yes. Librax can cause drowsiness.
Phentermine (Adipex) Lorazepam (Ativan) Yes. Phentermine should be taken early in the morning. If you take lorazepam once daily, bedtime is a great time, as it may cause drowsiness.
Phentermine (Adipex) Lorcet Plus (Acetaminophen with Hydrocodone) Yes. The Adipex (phentermine) should be taken early in the day and the Lorcet (acetaminophen with hydrocodone) only as needed. The Lorcet may also cause drowsiness. Be careful if you must be alert.
Phentermine (Adipex) Methylprednisolone (Medrol)
Yes. Both can increase your blood pressure so if you have high blood pressure or heart problems, talk to your doctor. Take the steroid methylprednisolone with food or milk to prevent GI problems.
Phentermine (Adipex) Nasonex and Lexapro in the morning; and Lunesta, Lasix, NyQuil and Benadryl at night If you are using Lunesta (eszopiclone), Benadryl (diphenhydramine) and NyQuil to help you sleep, there should be no need or reason to take all three. Talk to your physician. If you take Lasix (furosemide) for blood pressure, avoid NyQuil, as it contains a decongestant that can increase blood pressure.
Phentermine (Adipex) Naproxen (Naprosyn, Aleve) Yes. Take naproxen with food or milk to prevent stomach upset. Do not take phentermine if you have heart problems or high blood pressure, as it can cause heart rate and blood pressure to increase.
Phentermine (Adipex) NyQuil Yes. Take phentermine early in the morning and NyQuil only at bedtime. Do not take either if you have heart problems or high blood pressure. Talk to your physician.
Phentermine (Adipex) Plaquenil (Hydroxychloroquine) Yes. Take Plaquenil with food or milk. Phentermine can cause nervousness, agitation and sleeplessness, and is effective only for a limited time. Follow a proper diet and exercise regimen when taking a diet pill.
Phentermine (Adipex) Prednisone Taper Yes. Both are normally taken in the morning. Take prednisone with food to prevent stomach upset. Follow directions on the prednisone and take to completion.
Phentermine (Adipex) Pristiq (Desvenlafaxine) Yes. Take Adipex in the morning; and Pristiq, which is an SNRI, any time during the day. Both can cause elevated blood pressure. If you have heart problems or high blood pressure, talk to your physician before starting. Avoid alcohol.
Phentermine (Adipex) Pristiq (Desvenlafaxine), Zestril (Prinivil, Lisinopril) and Maxide (Triamterene with HCTZ) Yes. If you just started taking Zestril or Maxzide, you may have postural hypotension -- light-headedness when first getting up from bed or sitting. It generally goes away after a few doses, and your body adjusts to the reduced tension on your blood vessels. Avoid alcohol with Pristiq. Take phentermine early in the day to avoid sleep issues. If there are multiple doctors involved in these prescriptions and the prescriber of the phentermine is unaware of high blood pressure or heart issues, be sure everyone is aware. Phentermine can increase blood pressure.
Phentermine (Adipex) Protonix (Pantoprazole) Protonix is for GERD or stomach acid. Adipex is a diet tablet. I would not mix them, as Adipex has had problems in the past. But there are no drug interactions between the two.
Phentermine (Adipex) Tapazole (Methimazole) Yes.
Phentermine (Adipex) Tenormin (Atenolol) No. Tenormin is normally used to slow the heart rate and lower blood pressure. Phentermine can cause elevated blood pressure, palpitations and tachycardia.
Phentermine (Adipex) Toprol (Metoprolol) Yes. Did the same doctor prescribe both? Diet aids like phentermine can increase heart rate and blood pressure. This is what Toprol normally treats. Talk to your doctors before taking these.
Phentermine (Adipex) Valacyclovir (Valtrex) Yes. Take phentermine early in the morning and never take more than prescribed. Take valacyclovir as prescribed.
Phentermine (Adipex) Zyrtec (Cetirizine) Yes. Phentermine is only effective if taken for a few weeks. There are many problems with this drug, and I hope your physician is offering options for weight reduction. Take Zyrtec early in the day, and drink plenty of water.
Phenylephrine hcl (Robitussin PE) Citalopram (Celexa) and Levothyroxine (Synthroid) Citalopram has no interactions with levothyroxine or phenylephrine. But the effects of levothyroxine (a thyroid hormone) can be increased by phenylephrine (a sympathomimetic drug), especially if you have heart disease. Report palpitations, rapid heart beat or other unusual effects if using these drugs together is unavoidable. If you have nasal congestion, use saline nasal spray to moisturize the nasal passages, which will reduce swelling.
Plaquenil (Hydroxychloroquine) Penicillin Antibiotics Yes. There are no direct drug interactions between any type of penicillin and hydroxychloroquine. They are just as effective taken together as alone. Take hydroxychloroquine with food or milk. The type of penicillin called penicillin G should be taken on an empty stomach. Always take penicillin until complete.
Plaquenil (Hydroxychloroquine) Metoprolol (Toprol, Lopressor)
There is a minor chance of an interaction. The side effect of the beta blocker (metoprolol) may get worse with Plaquenil. If your heart rate or blood pressure drops too low while taking metoprolol, you may become dizzy or feel faint; do not stand or sit up too quickly. Contact your doctor immediately if you experience chest pain, difficulty breathing or shortness of breath, fainting or falling spells, or a slow heart rate. This would be more likely to happen if you have been taking metoprolol then add the Plaquenil.
PMS Caplets Azithromycin (Zithromax), Benzonatate (Tessalon), and Guaifenesin with Codeine (Robitussin AC) PMS is a medical condition, not a medication. I assume you are taking Midol PMS (acetaminophen with pyrilamine) or something similar.  There are no drug interactions. Take azithromycin until finished, benzonatate, guaifenesin and Midol as needed. The cough products and Midol PMS may cause drowsiness. Drink plenty of water.
Prednisone (Deltasone) Hydroxyzine (Atarax)  Yes. They may be taken together. Take prednisone with food or milk to prevent stomach irritation. Hydroxyzine can cause extreme drowsiness, so be careful if you have to be alert. 
Pristiq (Desvenlafaxine) Adderall Yes. Avoid alcohol.
Pristiq (Desvenlafaxine) Alcohol No. There is a possible major interaction -- concurrent use may result in an increased risk of central nervous system effects. Avoid alcohol completely.
Pristiq (Desvenlafaxine) Ali Yes. Take Pristiq at bedtime and Ali in the morning. Do not skip any doses of the Pristiq, and follow the directions on the Ali package. Do not take for any longer than prescribed. Avoid alcohol.
Pristiq (Desvenlafaxine) Ambien (Zolpidem) Yes. Be sure you can give eight hours for sleep while taking zolpidem. If you notice unusual drowsiness or dizziness or other psychological behavior changes, call your physician. Avoid alcohol.
Pristiq (Desvenlafaxine) Lunesta (Eszopiclone) Yes. Avoid alcohol.
Pristiq (Desvenlafaxine) Nasonex (Mometasone) Yes. Avoid alcohol. Nasonex works better for nasal allergies if used every day. Do not stop Pristiq unless by direction of the physician.
Pristiq (Desvenlafaxine) Neurontin (Gabapentin), Percocet (Oxycodone with Acetaminophen) and Avinza (Morphine Sulfate) Concurrent use of Percocet and Avinza -- as they are both opioid analgesic narcotics -- can result in additive respiratory depression. Concurrent use of gabapentin and morphine can result in an increase in gabapentin plasma concentrations. Do not take morphine and Percocet at the same time. Talk to your doctor about the Neurontin, and make sure your blood levels are monitored.
Pristiq (Desvenlafaxine) Paxil (Paroxetine) Talk with your physician. There can be a major drug interaction between these two. Studies have shown that concurrent use of desvenlafaxine and SSRIs (selective serotonin reuptake inhibitors -- like Paxil) can result in increased risk of serotonin syndrome (hypertension, hyperthermia, myoclonus and mental status changes). If different doctors prescribed these drugs, inform all your health care providers of what you're taking.
Pristiq (Desvenlafaxine) Pepcid Yes. Avoid alcohol.
Pristiq (Desvenlafaxine) Soma (Carisoprodol) Yes. They may be taken together. Soma is a muscle relaxant that can cause extreme drowsiness. If you must be alert, be careful and see how you react to this medication. Take this only when needed.
Pristiq (Desvenlafaxine) Tagamet (Cimetidine) Yes. I would suggest taking Pristiq early in the day. Avoid alcohol while taking Pristiq. Do not stop or change your dose without instructions by your physician.
Pristiq (Desvenlafaxine) Trazodone (Desyrel) Yes. Avoid alcohol, and take these as prescribed.
Promethazine (Phenergan) Ambien CR Yes. Both cause drowsiness. Take these as needed and the Ambien only if you can devote eight hours for sleep.
Promethazine (Phenergan) Celexa (Citalopram) If you are taking one in the morning and the other when you go to bed, this should be OK. Phenergan (promethazine) and citalopram (Celexa) may be used together with caution. Side effects such as confusion, drowsiness, increased heart rate, loss of coordination, restlessness, sweating, tremors, or vomiting may occur if you take these medicines together.
Promethazine (Phenergan) Naproxen (Naprosyn, Aleve) Yes. Promethazine can cause drowsiness.  Naproxen can upset the stomach, so take it with food or milk. Take these as needed.
Promethazine (Phenergan) NyQuil (Acetaminophen, Dextromethorphan, Doxylamine, Pseudoephedrine) Phenergan with NyQuil can cause extreme drowsiness. Phenergan causes pronounced sedation and when it's combined with other central nervous system depressants (dextromethorphan and doxylamine), additive drowsiness can occur. Avoid both if you must be alert. If you have high blood pressure or heart problems, talk to your doctor before taking any decongestant like pseudoephedrine. Take these as needed.
Promethazine (Phenergan) Ondansetron These antinausea drugs work differently. Most patients would take one or the other. You could take them both in the same day, but alternate doses and not take them simultaneously. Talk to the physician who prescribed these two drugs.
Promethazine (Phenergan) Two Percocets (Acetaminophen with Oxycodone) Do not take these together, unless you are closely monitored. A possible major side effect is an increase in central nervous system and respiratory depression. It is hard to breathe if you have respiratory depression. Talk to your physician.
Promethazine DM (Phenergan with Dextromethorphan) Lisinopril-HCTZ (Prinzide or Zestoretic) Yes. Take the lisinopril-HCTZ at the same time each day and the promethazine product only when needed.
Promethazine with Codeine (Phenergan with Codeine) Benzonatate (Tessalon) Yes, but side effects from these drugs may get worse if you take both together. If you notice slurred speech, confusion, severe weakness, or difficulty breathing while taking these medicines, contact your health care provider immediately. Take these only as needed and be careful if you must be alert.
Promethazine with Codeine Syrup NyQuil No. This would be a duplication of therapies and would cause extreme drowsiness, dry mouth and other side effects. Take one or the other, not both. Take only as needed. Drink plenty of water.
Propranolol (Inderal) Nasonex (Mometasone) Yes. There are no direct drug interactions between these two.
Propranolol (Inderal) Sertraline (Zoloft), Yasmin (Drospirenone/Ethinyl Estradiol), Alprazolam (Xanax) and Adderall XR (Mixed Amphetamine Salts) There are a couple possible drug interactions. Alprazolam with sertraline increases the risk of central nervous system depression, psychomotor impairment and sedation. Adding propranolol to these two can increase the risk of hypotension (low blood pressure). Be sure all your physicians and health care providers are aware of your medication regimen. Be careful if you must be alert, and have your blood pressure checked regularly.
Protonix (Pantoprazole Sodium) Fosamax (Alendronate Sodium) Yes. Fosamax is used for osteoporosis and should be taken by itself in the morning with a full glass of water. Protonix  -- for gastroesophageal reflux disease (GERD) -- can be taken at bedtime.
Protonix (Pantoprazole Sodium) Amlodipine (Norvasc) and Augmentin (Amoxicillin/Clavulanic Acid) Yes. Normally amlodipine is given in the morning, pantoprazole before breakfast or dinner and Augmentin two to three times daily with food. Take Augmentin until finished and the others every day.
Protonix (Pantoprazole Sodium) Cymbalta (Duloxetine) and Gabapentin (Neurontin) Yes. Normally Protonix is taken before the largest meal of the day.  Take the others as prescribed by your doctor.
Protonix (Pantoprazole Sodium) Methimazole (Tapazole) Yes. You may take them together.
Prozac (Fluoxetine) Ambien There is a possible risk of increasing a common side effect of both Prozac (fluoxetine) and Ambien (zolpidem) -- concurrent use may result in an increased risk of hallucinations. Take Ambien as needed and if you can devote eight hours for sleep. Do not stop taking Prozac without instruction from the prescribing physician.
Prozac (Fluoxetine) DayQuil or Any Aspirin No. The SSRI fluoxetine has major interactions with aspirin that can result in increased bleeding risk. Vicks DayQuil has acetaminophen, dextromethorphan and pseudoephedrine. The dextromethorphan (DM) with fluoxetine can result in dextromethorphan toxicity (nausea, vomiting, blurred vision, hallucinations) or serotonin syndrome (hypertension, hyperthermia, myoclonus, mental status changes). If you have a cold, talk to your pharmacist or doctor, and bring a list of your medications. If you have a fever or headache, take acetaminophen (Tylenol), and limit daily intake to 3000mg.
Prozac (Fluoxetine) Estroven (Nighttime) Yes. They may be taken at the same time if needed.
Prozac (Fluoxetine) Levsin (Hyoscyamine) Yes. Take fluoxetine daily at the same time, and do not stop or alter the dose without instruction by your physician. Hyoscyamine can dry your mouth and mucous membranes, so increase your fluid intake while taking this drug, unless otherwise instructed by your doctor.
Prozac (Fluoxetine) Mirapex (Pramipexole) There are no direct drug interactions between Mirapex (pramipexole) and Prozac (fluoxetine). They may be taken together, simultaneously.
Prozac (Fluoxetine) Rozerem (Ramelteon) Yes. Normally fluoxetine is given in the morning, and Rozerem is given at bedtime. Avoid alcohol.
Prozac (Fluoxetine) Tapazole (Methimazole) Yes.
Relora (Magnolia and Phellodendron Extracts) Thyroid Medicine Avoid Relora, a non-sedative herbal stress relief formula that allegedly helps people deal with general stress. This is an herbal product and as such, is not tested by the FDA for safety and effectiveness. The thyroid gland controls, or has part in, many of the body's organ systems and bodily functions. Any interruption or alteration in thyroid levels, can have a severe impact on your quality of life and function. Talk to your doctor before adding any medication or herbal to your drug regimen. Even if your thyroid level has been stable for years, you should have regular (at least yearly) thyroid hormone levels drawn.
Remeron Hydrocodone Yes. Both can cause drowsiness.
Robaxin (Methocarbamol) Adipex (Phentermine) Yes. The muscle relaxant Robaxin can cause drowsiness. Take it only as directed, when needed. If you have high blood pressure or heart problems, talk to your doctor before taking Adipex.
Robitussin (Guaifenesin) Fast-Acting Zyrtec Yes. They may be taken together if needed. Drink plenty of water with Robitussin. If your symptoms continue or worsen, contact your doctor.
Robitussin (Guaifenesin) Lexapro (Escitalopram) Yes. Take Robitussin as needed with plenty of water.
Robitussin (Guaifenesin) Metoprolol (Toprol, Lopressor), Spironolactone (Aldactone) and Lisinopril (Zestril,Prinivil) Robitussin is fine with each of these blood pressure medications. Problems arise with diuretics and high blood pressure medications. Spironolactone is a potassium-sparing diuretic, not normally used at the same time with ACE inhibitors, especially in the presence of renal impairment (kidney disease, elderly patients). These drugs can raise the level of potassium in the blood, but they can be used together safely with close monitoring. When the potassium level is too high, this can cause muscle weakness or an abnormal heart rhythm. If you experience extreme muscle weakness, chest pain, pounding heartbeat, or an unusually fast or slow heart beat, contact your health care provider immediately.

ACE inhibitors (Lisinopril) are used to lower blood pressure, or treat heart failure or kidney disease. Metoprolol is a beta blocker that slows the heart rate and helps lower blood pressure. If the blood pressure drops too low while taking these medications, you may become dizzy or feel faint. To limit this interaction, do not stand or sit up too quickly. Contact your physician if you have dizziness that does not go away.

Always have a discussion with your doctor and pharmacist regarding new medication added to your regimen, including side effects, possible interactions and expected results.
Robitussin (Guaifenesin) Motrin (Ibuprofen) Yes. Take both as needed. Take Robitussin with plenty of water and Motrin with food or milk.
Robitussin (Guaifenesin) NyQuil There are many different formulas of both Robitussin and Vicks NyQuil. If you are using plain Robitussin (guaifenesin), this should be OK with any NyQuil product, as long as they do not include an expectorant. I do not think any of the NyQuil products currently available have an expectorant, but ask your pharmacist to be sure. Follow label directions, and take as needed.
Robitussin (Guaifenesin) Oxycodone (Oxycontin) Yes. Be careful taking the oxycodone if you must be alert.
Robitussin (Guaifenesin) Vicoprofen (Hydrocodone and Ibuprofen) Yes. Both can cause drowsiness. Drink plenty of water when taking Robitussin or any expectorant.
Robitussin CF Excedrin Migraine There is a problem with the phenylpropanolamine in the Robitussin CF and the caffeine in Excedrin -- concurrent use may result in increased caffeine serum concentrations and toxicity (anxiety, irritability, insomnia, diuresis). If you must take these two, drink plenty of water and avoid other forms of caffeine. If you have high blood pressure or heart disease, avoid these drugs.
Robitussin CF Other Medications Dextromethorphan is contraindicated in patients receiving some antidepressants, those who take MAOIs or tri-cyclic antidepressants. Talk to your pharmacist about the proper over-the-counter medication for you, if you have a chronic condition or drug allergies. Only take products to treat the symptoms you are experiencing. Avoid multisymptom medications if you have just a single problem.
Robitussin CF Singular Yes. Take Singulair at the same time each day and Robitussin as needed with plenty of water.
Robitussin CF Cough and Cold Celebrex (Celecoxib) Yes. Take Celebrex (an NSAID) with food, and drink plenty of water with Robitussin products.
Robitussin DM (Guaifenesin/ Dextromethorphan) Albuterol Inhaler and Zyrtec D Yes but if you have high blood pressure or heart problems, talk to your doctor before using Zyrtec D. Drink plenty of water with Robitussin, and use these only as needed.
Robitussin DM (Guaifenesin/ Dextromethorphan) Atenolol (Tenormin) Yes. Take Robitussin as needed with plenty of water. Take atenolol every day.
Robitussin DM (Guaifenesin/ Dextromethorphan) Benzonatate (Tessalon) Yes. You can take them together. Drink plenty of water with the Robitussin product and use these only as needed.
Robitussin DM (Guaifenesin/ Dextromethorphan) Dimetapp Yes. Take both with plenty of water. If you have high blood pressure or heart problems, talk to your doctor before taking Dimetapp.
Robitussin DM (Guaifenesin/ Dextromethorphan) Hypertension Medicine Yes but if you have diabetes, be careful. There is sugar in Robitussin. Follow directions on the box and take as needed. Drink plenty of fluids to thin out secretions.
Robitussin DM (Guaifenesin/ Dextromethorphan) Lisinopril (Zestril or Prinivil) Yes. Take lisinopril at the same time each day. Take Robitussin as needed with plenty of water.
Robitussin DM (Guaifenesin/ Dextromethorphan) Metformin (Glucophage) Yes. Take the Robitussin with plenty of water and only as needed.
Robitussin DM (Guaifenesin/ Dextromethorphan) Pramipexole (Mirapex) Yes. They may be taken together if needed. Drink plenty of water with Robitussin DM and only take as needed.
Robitussin DM (Guaifenesin/ Dextromethorphan) Prozac (Fluoxetine) No. There has been documentation of rare but major problems with the concurrent use of dextromethorphan and fluoxetine which may result in dextromethorphan toxicity (nausea, vomiting, blurred vision, hallucinations) or serotonin syndrome (hypertension, hyperthermia, myoclonus, mental status changes). Talk to the doctors who prescribed these medications.
Robitussin DM (Guaifenesin/ Dextromethorphan) Sudafed (Pseudoephedrine) Yes. Follow the dosing instructions on the bottles. If you have high blood pressure, talk with your physician first.
Robitussin DM (Guaifenesin/ Dextromethorphan) Valium Yes. Both can cause drowsiness. Avoid alcohol. Drink plenty of water with the Robitussin, and take both only as needed.
Robitussin DM (Guaifenesin/ Dextromethorphan) Zyrtec D (Cetirizine with Pseudoephedrine) Yes. Take both with plenty of water. If you have high blood pressure or heart problems, talk to your doctor before taking Zyrtec D.
Robitussin PE (Guaifenesin with Phenylephrine) Antabuse (Disulfiram) Yes. Drink plenty of water with Robitussin. Avoid alcohol and caffeine with Antabuse. Antabuse and alcohol can cause severe nausea and vomiting. Antabuse and high concentrations of caffeine can result in increased risk of cardiovascular and cerebral excitation, which could be a problem if you have high blood pressure or heart problems.
Rolaids (Calcium Carbonate, Magnesium Hydroxide/ Simethicone)  Tenormin (Atenolol) Atenolol's effectiveness can be reduced by the interaction of either calcium or magnesium with the beta blocker. If you take atenolol first, usually it's prescribed once daily in the morning, you could take the Rolaids two hours afterward and later on throughout the day as needed. If you check your blood pressure at home, check daily and keep a log. Keeping track of your daily blood pressure is a way to tell if the medication is working and if something else might be causing an issue. Check your pressure at the same time each day.
Septra Alcohol No. Concurrent use of alcohol and sulfamethoxazole can cause a disulferam-like reaction (flushing, sweating, palpitations, drowsiness). Take the full course of Septra, drinking plenty of water. After a day or so, you may go back to a normal beverage life.
Septra (Bactrim, SMZ-TMP or Sulfamethoxazole with trimethoprim) Nasonex (Mometasone) Yes. Take the Septra until finished with plenty of water.
Sertraline (Zoloft) Comtrex Comtrex has different formulas. The most common acetaminophen, brompheniramine and pseudoephedrine. There are no direct drug interactions with this Comtrex and sertraline. Take Comtrex only as needed. The antihistamine can cause drowsiness.  Pseudoephedrine should be avoided if you have high blood pressure.  Limit total daily intake of acetaminophen (Tylenol) to no more than 3000mg per day. If you have a different formula of Comtrex or if you have other questions, talk to your pharmacist or physician.
Sertraline (Zoloft) Echinacea and Burdock Root There does not appear to be literature indicating drug interactions between sertraline (Zoloft), echinacea and Burdock root. The issue with herbal products is the FDA does not regulate their testing, manufacture or distribution. The NIH (National Institutes of Health) has issued the following statement:
"The U.S. Food and Drug Administration does not strictly regulate herbs and supplements. There is no guarantee of strength, purity or safety of products, and effects may vary. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs or supplements, you should speak with a qualified health care provider before starting a new therapy."

When you update your medication lists, add all vitamins, herbals and supplements to this list. Make sure your doctors and pharmacist have a current list.
Sertraline (Zoloft) Mylanta There are no direct drug interactions between sertraline (Zoloft) and Mylanta (aluminum hydroxide, magnesium hydroxide, simethicone). They may be taken together if needed.
Sibutramine (Meridia) Gabapentin (Neurontin) Yes. They may be taken together if needed.
Sinequan (Doxepin) Acai Berry Juice I cannot find any reliable journal articles about acai berry. Most are testimonials without scientific basis. I don't know why you are taking the acai berry, but if you are seeing a physician and having doxepin prescribed, I would suggest: stop the acai berry, and talk to the prescribing physician for an opinion on this herbal product based on your condition. If you are using the acai berry for weight loss, there are many better and more proven ways to lose weight. Talk to your physician about developing a plan for exercise and diet control. Even if the acai berry has no effect on the doxepin, herbal products are not regulated by the FDA and sometimes what you do not know is in the product can hurt you more than what is supposed to be in the product to help you. Do not stop taking doxepin without talking to the prescribing physician.
Singulair (Montelukast) Losartan (Cozaar) Yes. They may be taken together, but normally Singulair is given after dinner and losartan in the morning.
Stanozolol (Winstrol) Effexor This is dangerous! I do not recommend taking stanozolol for any reason other than the only indicated condition -- hereditary angioedema. This drug has a black box warning about the increased risk of a life-threatening liver condition that may be caused by the drug.
Sudafed (Pseudoephedrine) Aleve (Naproxen) Yes. If you have high blood pressure or heart problems, talk to your doctor before taking Sudafed. Many over-the-counter sinus and cold products -- including Aleve and Advil (ibuprofen) -- contain Sudafed. It constricts blood vessels.
Sudafed (Pseudoephedrine) Allegra (Fexofenadine) Yes, as long as it's plain Allegra, then you can add a decongestant to relieve nasal congestion. If you have high blood pressure or heart problems, talk to your doctor before taking any decongestant, as they constrict blood vessels causing more pressure on the heart.
Sudafed (Pseudoephedrine) Ambien (Zolpidem) Yes, but not at the same time. Sudafed can cause increased heart rate and keep you awake. If you have high blood pressure or heart problems, talk to your doctor before taking Sudafed. Take these as needed. Take Ambien only if you can devote eight hours or more for sleep.
 Sudafed (Pseudoephedrine) Aromasin (Exemestane)and Amitiza (Lubiprostone) Yes, but if you have high blood pressure or heart problems, talk to your doctor before taking Sudafed, a vasoconstrictor, which means it squeezes the blood vessels -- which works to reduce sinus congestion. Always talk to your pharmacist before purchasing any over-the-counter medications.
Sudafed (Pseudoephedrine) Ativan (Lorazepam) Yes. Ativan can cause drowsiness. If you have high blood pressure or heart problems, talk to your doctor before taking Sudafed. Take these as needed.
Sudafed (Pseudoephedrine) Azithromycin (Zithromax) and Advil (Ibuprofen)  Yes. If you have high blood pressure or heart problems, talk to your doctor before taking Sudafed. Take azithromycin until finished. Take the others as needed.
Sudafed (Pseudoephedrine) Bactrim (TMP-SMZ, trimethoprim sulfamethoxazole, Septra)  Yes. If you have high blood pressure or heart disease, speak to your doctor before taking any oral decongestants.
Sudafed (Pseudoephedrine) Chlorpheniramine and Hydrocodone Yes. Chlorpheniramine and hydrocodone can cause drowsiness and loss of alertness. Hydrocodone can cause stomach upset, so take it with food or milk.
Sudafed (Pseudoephedrine) Clindamycin (Cleocin) Yes. They may be taken together. If you have high blood pressure or heart problems, talk to your doctor before taking Sudafed.
Sudafed (Pseudoephedrine) Coreg (Carvedilol) No. Coreg lowers blood pressure by reducing constriction of blood vessels. Pseudoephedrine is a decongestant that constricts blood vessels, particularly in sinuses and nasal passages.  Generally a person with high blood pressure or heart problems should not take any oral decongestant. Talk to your physician before taking Sudafed.
Sudafed (Pseudoephedrine) Delsym (Dextromethorphan) Yes. If you have high blood pressure or heart disease, speak to your doctor before taking any oral decongestants like Sudafed.
Sudafed (Pseudoephedrine) Hydrocodone Yes. If you have high blood pressure or heart problems, talk to your doctor before taking Sudafed.
Sudafed (Pseudoephedrine) Lexapro (Escitalopram) and Abilify (Aripiprazole) Yes. Take Sudafed only if needed. if you have high blood pressure or heart problems, talk to your doctor before taking any oral decongestant like Sudafed.
Sudafed (Pseudoephedrine) Librax (Clidinium with Chlordiazepoxide) Yes. If you have high blood pressure or heart problems, talk to your doctor before taking Sudafed. Librax can cause drowsiness.
Sudafed (Pseudoephedrine) Lisinopril (Prinivil, Zestril) If you are taking lisinopril for high blood pressure or heart problems, talk to your doctor before taking Sudafed. It constricts blood vessels, and may decrease Lisinopril's effectiveness by increasing blood pressure, or increasing the risk of palpitations or other side effects.
Sudafed (Pseudoephedrine) Muscle Relaxer Yes. If you have high blood pressure or heart problems, talk to your doctor before taking Sudafed.
Sudafed (Pseudoephedrine) Omeprazole (Prilosec) Yes. They may be taken together if needed. If you have high blood pressure or heart problems, talk to your doctor before taking any oral decongestant like Sudafed.
Sudafed (Pseudoephedrine) Percocet (Oxycodone with Acetaminophen) Yes. Percocet can cause drowsiness. Take with food or milk to avoid stomach upset. If you have high blood pressure or heart problems, talk to your doctor before taking Sudafed. Take only as needed.
Sudafed (Pseudoephedrine) Phenoxymethylpenicillin Yes. Take penicillin until finished and Sudafed as needed. If you have high blood pressure or heart problems, talk to your doctor before taking Sudafed.
Sudafed (Pseudoephedrine) Pristiq (Desvenlafaxine) Yes. They could be taken together if needed. If you have high blood pressure or heart problems, talk to your doctor before taking Sudafed.
Sudafed (Pseudoephedrine) Prozac (Fluoxetine) Yes. If you have high blood pressure or heart problems, talk to your doctor before taking Sudafed.
Sudafed (Pseudoephedrine) Robitussin (Guaifenesin) Yes, as long as you have plain Sudafed and plain Robitussin, they can be taken together. Drink plenty of water.
Sudafed (Pseudoephedrine) Valtrex (Valacyclovir) Yes. If you have high blood pressure or heart disease, please speak to your doctor before taking the pseudoephedrine.
Sudafed (Pseudoephedrine) Zoloft (Sertraline) Yes. If you have high blood pressure or heart disease, speak to your physician before taking any oral nasal decongestant.
Sudafed 12-Hour Lexapro (Escitalopram) Yes. If you have high blood pressure or heart problems, talk to your doctor before taking Sudafed. Take Lexapro as instructed and Sudafed as needed.
Sudafed 12-Hour Non-Drowsy Micardis HCT (Telmisartan with Hydrochlorothiazide) Do not take Sudafed if you have high blood pressure or heart problems without talking to your physician. Sudafed constricts blood vessels, which increases blood pressure and strains the heart. Micardis HCT is used to control high blood pressure and fluid retention.
Sudafed PE (Phenylephrine) Allegra (Fexofenadine) Yes. As long as it's plain Allegra, not the D version. Take Sudafed only as long as you have congestion. Drink plenty of water with both medications.
Sudafed PE (Phenylephrine) Benicar Talk to your physician. People with high blood pressure should avoid decongestants -- which include the phenylephrine in Sudafed PE and the pseudoephedrine in Zyrtec D. Nasacort (triamcinolone) spray is a topical steroid that reduces inflammation and shrinks nasal passages. Normal saline (Ocean) nasal spray moistens the nasal membranes, reducing congestion and allowing you to breath easier. If you have a humidifier on you furnace, turn it up to the highest setting in winter.
Sudafed PE (Phenylephrine) Citalopram (Celexa) Yes, but do not to take Sudafed late in the day. It could keep you awake. If you have high blood pressure or heart problems, talk to your doctor before taking any decongestant.
Sudafed PE (Phenylephrine) Effexor (Venlafaxine) Yes. If you have high blood pressure or heart problems, talk to your doctor before taking Sudafed.
Sudafed PE (Phenylephrine) Hydrochlorothiazide (HCTZ) No. If you have high blood pressure or heart problems, talk to your doctor before taking Sudafed PE.
Sudafed PE (Phenylephrine) Hydroxyzine Yes. Hydroxyzine is a Piperazine type antihistamine used most commonly for allergic reactions. It can cause extreme drowsiness. Sudafed PE is a decongestant. Avoid alcohol. Take both only as needed. If you have high blood pressure or heart problems, talk to your doctor before taking Sudafed PE.
Sudafed PE (Phenylephrine) Lexapro (Escitalopram) Yes. Take Sudafed only as long as you have congestion. To reduce congestion, take hot misty showers, use saline nasal sprays and drink lots of water.
Sudafed PE (Phenylephrine) Mirapex Yes. If you have high blood pressure or heart problems, talk to your doctor before taking Sudafed.
Sudafed PE (Phenylephrine) Paxil (Paroxetine) Yes. Be sure the doctor who prescribed the Paxil knows the patient is taking Sudafed as needed.
Sudafed PE (Phenylephrine) Singulair Yes. Take Singulair at the same time daily. Take Sudafed as needed with plenty of water.
Tagamet 200 (Cimetidine) Ritalin LA 30mg (Mixed Amphetamine Salts) The only problem is the time-release mechanism in Ritalin is pH dependent to properly work. Tagamet stops stomach acid, which would cause the pH in the stomach to change. The time-release mechanism used in Ritalin LA has been tested and shown not to be as affected by acid reducers. You should have no problem with these two together. If you do have problems, talk to your doctor.
Tegretol Alcohol and Adderall There are major to severe interactions between all three. Alcohol should never be mixed with Adderall or Tegretol. Adderall may decrease effectiveness of Tegretol by lowering the threshold for seizures. If you see more than one physician, inform all of them about your medications.
Tenormin (Atenolol) L-Arginine Yes. Take atenolol at the same time each day.
Tetracycline Atarax (Hydroxyzine), Cymbalta (Duloxetine) or Buspar (Buspirone) Patients under 14-16 should not take tetracycline, due to the risk of discoloration in the permanent teeth. Once all adult teeth are present, there should not be problems. This should be taken on an empty stomach at least 2 hours apart from vitamins, minerals, or antacids and dairy products. There are some reports of increased effects of Buspar  when taken with SSRIs like Cymbalta. Buspar and Atarax can cause drowsiness. Taken together may have an additive effect. Discuss your questions with your physician when any new prescription is written.
Tetracycline Mirapex (Pramipexole) Yes. They may be taken together. Tetracycline should only be taken on an empty stomach and should not be taken
within 2-3 hours of any antacid, milk or calcium product.
Topamax (Topiramate) Ativan and Ambien (Zolpidem) Yes. Although an interaction is possible, Topamax and Ativan are often used together with close monitoring. You may feel drowsy or more tired when taking these drugs together. Do not drive or operate machinery until you know how these drugs affect you. If you experience a seizure or notice any new or worsening side effects such as confusion, difficulty staying alert, dizziness, abnormal eye movements, irritability, difficulty walking, tremors or changes in mood, notify your health care provider.

Topamax and Ambien do not interact.

Ambien and Ativan must be used together with caution. Because these drugs are duplicate therapies (same drug class), there is an increased risk of side effects. Leave at least 6 to 8 hours between doses of these two drugs.

Discuss possible interactions and side effects with your physician.
Topamax (Topiramate) Lorazepam (Ativan) Yes. Although an interaction is possible, Topamax and lorazepam are often used together with close monitoring. You may feel drowsy or more tired when taking these drugs together. Do not drive or operate machinery until you know how these drugs affect you. If you experience a seizure or notice any new or worsening side effects such as confusion, difficulty staying alert, dizziness, abnormal eye movements, irritability, difficulty walking, tremors or changes in mood, notify your health care provider.
Topamax (Topiramate) Meloxicam (Mobic) and Cymbalta (Duloxetine)  Although an interaction is possible, Cymbalta and meloxicam are often used together. Taking them together may increase thinning of the blood. You may bruise or bleed more easily. Discuss any new or worsening side effects with your health care provider. Discuss your medications with your health care provider prior to any surgeries or procedures. Topiramate can be taken with either of the others without problem.
Tramadol (Ultram) Ceftin (Cefuroxime) Yes. They may be taken together. Take Ceftin until it is finished and tramadol as needed.
Tramadol (Ultram) Naproxen (Naprosyn) Yes. They may be taken together if needed. As tramadol can cause drowsiness, take this at night. Take naproxen with food or milk to protect your stomach.
Tramadol (Ultram) Unisom (Diphenhydramine) You may feel drowsy or more tired when taking these drugs together. This effect may last for a few days after you stop taking these drugs together. Do not drive or operate machinery until you know how these drugs affect you. If you notice slurred speech, confusion, severe weakness or difficulty breathing, contact your physician immediately. Take each of these only as needed.
Tums Estroven Yes. Estroven is a non-FDA tested, nonprescription dietary supplement containing vitamins, minerals, isoflavones and an herbal blend for nutritional supplementation. Tums is calcium carbonate.
Ultram (Tramadol) Allegra (Fexofenadine) Yes. Both can cause drowsiness. Take both only as needed.
Ultram (Tramadol) Ativan (Lorazepam) Yes. Both can cause drowsiness. Take both only as needed.
Ultram (Tramadol) Beta Blockers Yes. There are no direct drug interactions or contraindications between tramadol and any beta blocker product, including the timed-release, short- and long-acting beta blockers. Tramadol does interact with many medications, though, so be sure all your health care providers have a current list of all your medications. Tramadol can cause drowsiness, and beta blockers can slow down the heart. If you must be alert, be careful taking the tramadol.
Ultram (Tramadol) Celebrex (Celecoxib) Yes. Take Celebrex with food. Ultram can cause drowsiness.
Ultram (Tramadol) Erythromycin and Methylprednisolone (Medrol) There is one remotely possible drug interaction between tramadol, erythromycin and methylprednisolone. Because tramadol and erythromycin are broken down by similar mechanisms in the liver, the blood levels of tramadol may be increased if erythromycin is added.  This can lead to an increase in the side effects of tramadol (mostly central nervous system). I believe this would be only with high doses of tramadol, and it is only temporary while taking erythromycin. Be sure to take methylprednisolone with food to avoid stomach upset.  Erythromycin can also be a GI irritant, and it can be taken with food.
Ultram (Tramadol) Flagyl (Metronidazole) Yes. Take the metronidazole with food, until finished and the tramadol only when needed.
Ultram (Tramadol) Naproxen (Naprosyn, Aleve) Yes. Both may be used for pain. Aleve is also indicated for inflammation. Take these as needed and Aleve with food or milk to avoid stomach upset. Avoid alcohol with tramadol to preclude respiratory depression and severe central nervous system depression.
Ultram (Tramadol) Naproxen and Flexeril Ultram is a non-narcotic pain reliever. Flexeril (cyclobenzaprine) is a muscle relaxant. Naproxen is a nonsteroidal anti-inflammatory drug. Ultram and Flexeril can cause drowsiness, and there are reports that these two together may result in an increased risk of seizures. At the very least, be careful taking these together if you must be alert. Take naproxen with food or milk. Ultram and Flexeril may also be taken with food or milk.
Ultram (Tramadol) Nyquil (Acetaminophen, Dextromethorphan, Doxylamine and Pseudoephedrine) There can be a drug interaction between these two. Doxylamine is an antihistamine. You may feel drowsy or more tired when taking Ultram with any antihistamine. Many nonprescription allergy, cough and cold, and sleep products contain doxylamine, or more commonly other antihistamines (diphenhydramine/chlorpheniramine). Carefully read labels before taking any medicine with Ultram or other prescription pain-relievers. If you have heart disease or high blood pressure, pseudoephedrine in the Nyquil can cause problems. Talk to your doctor before taking oral decongestants if you have high blood pressure.
Ultram (Tramadol) Prednisone Yes. Take the prednisone with food or milk, until finished or as directed by your doctor.
Ultram (Tramadol) Zoloft (Sertraline) Major drug interaction -- concurrent use may result in increased risk of seizures and serotonin syndrome (hypertension, hyperthermia, myoclonus, mental status changes). Do not stop the Zoloft until you have spoken to the prescribing doctor. If you have pain and can take either acetaminophen or ibuprofen, do this in the meantime.
Unisom (Doxylamine) Cymbalta (Duloxetine) Yes. Unisom should only be taken before sleep. This drug will cause drowsiness, so be careful if you must be alert or get up in the night.
Valium (Diazepam) Diovan, Advair and Veramyst with a CPAP Machine Yes. Take Valium just before bedtime, as it can cause drowsiness. Diovan (valsartan) slows the heart, so it also may cause drowsiness. Use the inhalers as directed on a regular basis. These will help the inflammation in the airways and help you breathe. Use your CPAP as instructed, as this will help you breathe, as well as help you sleep.
Valium (Diazepam) Diclofenac (Voltaren) Yes. Only take the Valium if needed.
Valsartan (Diovan) Coricidin HBP (Acetaminophen with Chlorpheniramine) Yes. The other forms of Coricidin have an added decongestant that can affect blood pressure and should be avoided if you have high blood pressure or heart problems. Take valsartan every day at the same time and Coricidin HBP only when needed. Drink plenty of water with the cold tablet and make sure to keep your daily intake of acetaminophen (Tylenol) to less than 3000mg.
Valsartan (Diovan) Pristiq (Desvenlafaxine) Yes. They may be taken together if needed.
Vicks for Cold and Flu (Alcohol-Free) Sertraline (Zoloft) and Clonazepam (Klonopin) Check the label of the Vicks Cold and Flu product. If it contains dextromethorphan (DM), it could interact with the sertraline and cause a serotonin reaction-- increased risk of confusion, increased blood pressure or heart rate, loss of coordination, restlessness, sweating, tremor, vomiting or other side effects. Avoid anything with dextromethorphan. Clonazepam is OK to take with the Vicks.
Vitamin D Supplements Paxil CR (Paroxetine) Yes. They may be taken together if needed.
Wellbutrin (Bupropion) Adderall and Atenolol (Tenormin) Yes. Avoid alcohol.
Wellbutrin (Bupropion) Chantix (Varenicline) Yes. If you are considering using a nicotine patch also, and you have high blood pressure, please talk to the doctor before using a patch with the Wellbutrin (or Zyban). The two together can increase the blood pressure.
Wellbutrin (Bupropion) Codeine Yes. Take bupropion as directed each day and codeine as needed with food to avoid stomach upset.
Wellbutrin (Bupropion) Flexeril (Cyclobenzaprine) Yes. Both can cause drowsiness. Take Wellbutrin regularly. Take Flexeril only as needed.
Wellbutrin (Bupropion) HCTZ (Hydrochlorothiazide) Yes. They may be taken together if needed.
Wellbutrin (Bupropion) Hydroxychloroquine (Plaquenil) Yes. They may be taken together. Take hydroxycholoroquine with milk or food to avoid stomach upset. Tell all your health care providers about all your medications. Several drugs do interact with these two.
Wellbutrin (Bupropion) Neurontin, Percocet, Excedrin Migraine and Tylenol PM No drug interactions, but duplications of therapy that could cause added side effects. Tylenol PM (acetaminophen with diphenhydramine) should only be taken at bedtime. Percocet (oxycodone with acetaminophen), Tylenol PM and Excedrin products all contain acetaminophen. Limit your daily intake of acetaminophen to 3000mg, so keep track. Any of these drugs can cause drowsiness, so taking multiples can have an additive effect. Take Neurontin (gabapentin) and Wellbutrin as prescribed. The others take as needed.
Wellbutrin (Bupropion) Nizoral (Ketoconazole) Yes. Take Nizoral with food. Wellbutrin can cause drowsiness. Avoid alcohol.
Wellbutrin (Bupropion) NyQuil There is a possible drug interaction, depending upon which Vicks NyQuil formula you have. If you have the one with a decongestant (pseudoephedrine), taken with the Wellbutrin in high doses can increase the risk of seizures. Talk to the physician who prescribes the Wellbutrin.
Wellbutrin (Bupropion) Percocet (Oxycodone with Acetaminophen) Yes. Both can cause drowsiness. Take them with food if they upset your stomach.
Wellbutrin (Bupropion) Protonix (Pantoprazole) Yes.
Wellbutrin (Bupropion) Tylenol Extra Strength and Midol You can take Wellbutrin with either Tylenol (acetaminophen) or Midol (pyrilamine with acetaminophen). Do not take Tylenol and Midol together. They both contain acetaminophen. An alternative would be to use ibuprofen with Midol. This would be fine with Wellbutrin. Limit acetaminophen to 3000mg per day and if you take NSAIDs (nonsteroidal anti-inflammatory drugs), like ibuprofen, take them with food or milk.
Wellbutrin (Bupropion) Vistaril (Hydroxyzine) and Zoloft (Sertraline) Vistaril may be taken with either Wellbutrin or Zoloft but taking the Wellbutrin with Zoloft may have an additive effect: literature indicates concurrent use may result in increased plasma levels of sertraline. Are these prescribed by the same doctor? It is possible that this effect is what the doctor is attempting to achieve. Talk to your doctor. Any of these can impair your judgment or cause drowsiness.
Wellbutrin (Bupropion) Zoloft (Sertraline) and Klonopin Taking Wellbutrin and Zoloft together may result in increased plasma levels of sertraline, meaning Zoloft side effects could be more likely or intensive. These include: sweating, constipation, diarrhea, indigestion, loss of appetite, nausea, vomiting, dry mouth, myalgia, dizziness, headache, insomnia, somnolence, tremor, vision disturbance, agitation, abnormal ejaculation, reduced libido, yawning and fatigue. Do not take Zoloft if you are a teen or younger without close supervision. Avoid alcohol.
Xanax as Needed (Alprazolam) Methadone Yes. Both can cause drowsiness. Taken together can have an additive effect. If you must be alert, be careful.
Xanax  (Alprazolam) Cholesterol-Lowering Medication I could not find any results of drug interactions between Xanax and any product used for cholesterol lowering, including of the statins, fenofibrates, bile sequestering agents and niacin.  They may be taken together. Xanax can cause drowsiness.
Xanax  (Alprazolam) Flexeril (Cyclobenzaprine) Xanax and Flexeril both cause drowsiness, so you may feel drowsy or more tired when taking these drugs together. This effect may last for a few days after you stop taking these drugs together. Do not drive or operate machinery until you know how these drugs affect you. If you notice slurred speech, confusion, severe weakness or difficulty breathing, contact your health care provider immediately.
Zicam Extreme Congestion (Oxymetazoline) Advil PM (Ibuprofen with Diphenhydramine) Yes. If you have high blood pressure or heart problems, talk to your doctor before using Zicam. Use Advil with caution if you have GI or stomach problems, as it can irritate the stomach lining. Take Advil PM only if you can devote eight hours for sleep.
Zocor (Simvastatin) Echinacea Yes.
Zocor (Simvastatin) Yasmin (BCP) Yes. Take Yasmin in the morning and Zocor after the evening meal or at bedtime.
Zofran (Ondansetron) Fever-Reducer Yes. You can use any over-the-counter fever-reducer (Tylenol, Motrin). Zofran is a very effective antinausea drug that can cause drowsiness. Take as needed.
Zofran (Ondansetron) Tums There are no direct drug interactions between Zofran (ondansetron) and Tums (calcium carbonate). They may be taken together if needed.
Zoloft (Sertraline) Avelox (Moxifloxacin), Ativan (Lorazepam) and Klonopin (Clonazepam) Yes, but concurrent use may result in increased sedation. You can take Avelox, an antibiotic, with any or all of the others. Take it until finished. Take all as directed, and do not alter doses without being instructed by your physician.
Zoloft (Sertraline) Biaxin, Triamterene Hctz and Cheratussin AC syrup Yes. Finish the Biaxin, and take the cough syrup as needed. Drink plenty of water with the Cheratussin.
Zoloft (Sertraline) Buspirone (Buspar) Yes. If your physician has said to, they may be taken together. Both can cause drowsiness. Avoid alcohol with both anti-anxiety medications and SSRIs. Do not abruptly stop either of these drugs and always follow the prescribing physician's advice. Do not take over-the-counter medications without speaking to your pharmacist first.
Zoloft (Sertraline) Clonazepam (Klonopin) Yes. They may be taken together, but both can cause drowsiness.
Zoloft (Sertraline) Cold Medicines There are no direct drug interactions between Zoloft and the most common decongestants, antihistamines, expectorants or cough suppressants. Be careful adding new medications, and notify your doctor about side effects.
Zoloft (Sertraline) Echinacea and Burdock Root There does not appear to be any literature indicating drug interactions between echinacea and Burdock root. The issue with herbal products is that the FDA does not regulate their testing, manufacture or distribution. The NIH (National Institutes of Health) has issued this statement:

The U.S. Food and Drug Administration does not strictly regulate herbs and supplements. There is no guarantee of strength, purity or safety of products, and effects may vary. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs or supplements, talk with a qualified health care provider before starting a new therapy."
Zoloft (Sertraline) Pseudoephedrine HCl Yes. There are no direct drug interactions between Zoloft and pseudoephedrine (Sudafed).  They may be taken together. If you have high blood pressure or heart disease, talk with your physician before taking any oral decongestant (like pseudoephedrine).
Zoloft (Sertraline) Qvar (Beclomethasone) Yes. After using the Qvar, be sure to rinse your mouth thoroughly to remove any drug left in the mouth.
Zoloft (Sertraline) Synthroid (Levothyroxine) Yes. They may be taken together. Synthroid should be taken early in the morning prior to any food. One problem that can occur: if you have been taking Synthroid for a while and are stable at a dose, then adding (or removing) Zoloft could affect your blood levels of the thyroid replacement. Anyone taking a thyroid replacement drug (like Synthroid) should be getting at the very least, one blood level drawn each year. Even if you have been at a stable dose for years, this should be done. If your medication regimen changes, be sure to update your medication list with the physician who prescribed the thyroid replacement.
Zoloft (Sertraline) Tylenol Cough & Sore Throat Yes.
Zoloft (Sertraline) Tylenol Sinus Congestion & Pain Yes. Take Zoloft daily as prescribed. Take the cold medication as needed.  If you have high blood pressure, heart problems or prostate problems, talk to your doctor before taking the Tylenol product.
Zoloft (Sertraline) Vicks Formula 44 Custom Care Chesty Cough (Dextromethorphan, Guaifenesin and Pseudoephedrine) There is a possible interaction between Zoloft and Vicks Formula 44 Chest & Cough. These drugs are sometimes used together, but this combination may increase the risk of confusion, increased blood pressure or heart rate, loss of coordination, restlessness, sweating, tremor, vomiting or other side effects. Report increased side effects to your doctor. Do not exceed recommended doses of cough products containing dextromethorphan, and report troublesome effects.
Zoloft (Sertraline) Vicks NyQuil Yes. Take Zoloft in the morning and NyQuil at bedtime. If you take them together, there may be an increased chance for drowsiness. Take NyQuil as needed.
Zyrtec (Cetirizine) Allegra (Fexofenadine) Both Zyrtec (cetirizine) and Allegra (fexofenadine) are long acting, non drowsy antihistamines. They should not be taken together or the same day.
Zyrtec (Cetirizine) Atarax (Hydroxyzine) Although there are no direct drug interactions between Atarax and Zyrtec, due to the duplicative pharmacology and potential for additive side effects, combining hydroxyzine with other antihistamines is not recommended. Both can cause drowsiness -- with Atarax, pronounced sedation.  Talk to your doctor before taking these two.
Zyrtec (Cetirizine) Advil Cold & Sinus Yes but if you have GI problems (ulcers), or heart problems or high blood pressure, talk to your doctor before taking Advil Cold and Sinus. Take both only as needed.
Zyrtec (Cetirizine) Advil PM (Ibuprofen with Diphenhydramine) One big problem is that the PM part of the Advil is an antihistamine and so is the Zyrtec. Most patients take Zyrtec in the morning. You should take Advil PM only at bedtime. You may see an increase in sleepiness.
Zyrtec (Cetirizine) Aleve-D (naproxen with pseudoephedrine) Yes. They may be taken together if needed. If you have high blood pressure or heart disease, please speak to your doctor before taking any oral decongestant.
Zyrtec (Cetirizine) Bayer Extra-Strength Yes. You may take them together.
Zyrtec (Cetirizine) Benzonatate (Tessalon) Yes. They may be taken together. Take only as needed.
Zyrtec (Cetirizine) Coricidin HBP (Acetaminophen with Chlorpheniramine) There is duplication of antihistamines. Coricidin HBP is a short-acting, sedating antihistamine. Zyrtec is a long-acting, mostly nonsedating antihistamine. Theoretically you do not need both. If you take the Coricidin product, be careful if you must be alert.
Zyrtec (Cetirizine) Delsym and Albuterol Yes. You may take them together. Normally Zyrtec is given once daily, Delsym twice daily if needed and the albuterol 3 to 4 times daily in the tablet form or up to 6 times daily inhaled. Take these as needed (or as prescribed by your physician) and with plenty of water.
Zyrtec (Cetirizine) Flonase Yes. Both are normally used once daily in the morning. Even though Flonase is a steroid product, its long-term use does not cause problems.
Zyrtec (Cetirizine) Klonopin (Clonazepam) Yes. Both can cause drowsiness.
Zyrtec (Cetirizine) Levothyroxine (Synthroid) Yes. They can be taken together. Be sure your physician has your blood thyroid level check yearly to ensure the proper dosing.
Zyrtec (Cetirizine) Lisinopril (Prinivil or Zestril) Yes. They may be taken together if needed.
Zyrtec (Cetirizine) Lunesta (Eszopiclone) Yes. Be sure you have eight hours to devote for sleep. If you do not, you run the risk of not being fully alert the following day. Taking the Zyrtec can increase the drowsiness. Avoid alcohol.
Zyrtec (Cetirizine) Nasonex (Mometasone) and Celebrex (Celecoxib) Yes. Take Celebrex with food to protect the stomach.
Zyrtec (Cetirizine) Norvasc Yes. Both are usually taken in the morning. Whatever time you take each one, take it at the same time each day.
Zyrtec (Cetirizine) NyQuil (Acetaminophen, Dextromethorphan, Doxylamine, Pseudoephedrine) Yes, however, if you take Zyrtec in the morning and NyQuil only at bedtime, there would be duplication of the antihistamine, which may cause extra drowsiness. If you allow 6 to 8 hours for sleep and are careful when getting up, it should not be a problem. If you have prostate problems, talk to your doctor before taking any antihistamine. If you have heart problems or high blood pressure, do not take any oral decongestant before talking to your doctor.
Zyrtec (Cetirizine) Other Medications There are few articles regarding drug interactions with long-acting antihistamines like Zyrtec, mostly discussing additive side effect problems -- drowsiness and dry mouth/mucous membranes.  Avoid alcohol and central nervous system depressants. Do not duplicate medication types, so avoid cough and cold medications that include antihistamines. Take your medication list to your pharmacy and have them check for specific problems with the medications you take.
Zyrtec (Cetirizine) Phenylephrine HCI Yes. If you have high blood pressure or heart problems, talk to your physician first. The decongestant can increase your blood pressure and constrict your blood vessels. If you can take both, consider Zyrtec D, which has an antihistamine/decongestant already in it.
Zyrtec (Cetirizine) Pseudoephedrine (Sudafed) Yes. They may be taken together and are actually in one pill, Zyrtec D. If you have high blood pressure or heart problems, talk to your physician before taking the decongestant pseudoephedrine.
Zyrtec (Cetirizine) Promethazine (Phenergan) Do not take the Zyrtec (cetirizine) and promethazine (Phenergan) together without speaking to your physician first. These drugs may be used by someone at different times in the same day, but there is a risk of drowsiness and confusion.
Zyrtec (Cetirizine) Pseudoephedrine 12-Hour(Sudafed) If you are an adult and it is plain Zyrtec, you may take these together. If you have high blood pressure or heart problems, talk to your doctor before taking any decongestant like Sudafed. Drink plenty of water.
Zyrtec (Cetirizine) Robitussin Cough and Cold, and Tylenol Yes. Drink plenty of water with Robitussin. If you have high blood pressure or heart problems, talk to your doctor before taking this drug. Limit Tylenol to 3000mg in 24 hours. Take these as needed.
Zyrtec (Cetirizine) Tessalon (Benzonatate) Yes. Take both as needed for allergies and cough. Tessalon can cause drowsiness and even though the Zyrtec is nonsedating, its main side effect is drowsiness. Drink plenty of fluids.
Zyrtec (Cetirizine) Tramadol (Ultram) Yes, but you have a chance of increasing the side effect of drowsiness.
Do not drive or operate machinery until you know how these drugs affect you. Many nonprescription cough and cold products contain antihistamines. Read labels before taking any medicine with tramadol. Take these only as needed.
Zyrtec (Cetirizine) Triaminic Chest & Nasal Congestion The Triaminic product you refer to has pseudoephedrine hydrochloride and guaifenesin -- a decongestant and an expectorant. Zyrtec is an antihistamine. If you have plain Zyrtec, you may take this Triaminic product with the Zyrtec. If the ingredients are different from what I specified for the Triaminic or if the Zyrtec is the combination product Zyrtec D, do not take them together. Drink plenty of water with these. To be absolutely safe, take the Triaminic bottle to the pharmacy where you had the Zyrtec prescription filled, and have the pharmacist verify the ingredients against your medication profile. If you have high blood pressure, a decongestant can make your pressure go up. If you have glaucoma, an antihistamine can increase your ocular pressure.
Zyrtec (Cetirizine) Valium (Diazepam) There is a chance of a moderate drug interaction. You may feel drowsy or more tired when taking these together. Never take more of either these drugs than directed.
Zyrtec (Cetirizine) Wellbutrin (Bupropion) Yes. If either makes you drowsy, taking the two could increase the chance of drowsiness. Avoid alcohol.
Zyrtec (Cetirizine) Zolpidem The only likely interaction is the chance to increase drowsiness, especially in the morning. Even though an interaction is possible, these drugs are often used together. You may feel drowsy or more tired when taking these drugs together. Do not drive or operate machinery until you know how these drugs affect you.
Zyrtec (Cetirizine) 24-Hour Allegra D (Fexofenadine with Pseudoephedrine) 24-Hour There is absolutely no reason to take both . . . they both are long-acting antihistamines. Allegra D has the added decongestant. If you need a decongestant, and you do not have high blood pressure or heart problems, take Allegra D. If all you need is the antihistamine,  take Zyrtec. Do not take both the same day.
Zyrtec D (Cetirizine with Pseudoephedrine) Adderall (Mixed Amphetamine Salts) No. Do not take amphetamine products or diet pills, and cold products containing pseudoephedrine together. Taking Adderall with pseudoephedrine can increase the risk of high blood pressure, nervousness, palpitations, sleep problems or other serious side effects. Always discuss your medications with a pharmacist before choosing an over-the-counter cough or cold product.
Zyrtec D (Cetirizine with Pseudoephedrine) Celebrex (Celecoxib) Yes. Take Celebrex with food or milk to protect the stomach.  If you have high blood pressure or heart problems, talk to your doctor before taking any decongestant.
Zyrtec D (Cetirizine with Pseudoephedrine) Colchicine, Vitamin D,  Metagenics Cholarest SC and BioMatrix Support Adrenals with the 2009 seasonal flu shot and the H1N1 flu shot Colchicine can interact with the cyanocobalamin in support adrenals (multiple vitamins, minerals and flavonoids), which could inhibit absorption of the vitamin. Nothing major. Flu vaccines will not interact with any of these. When you get the vaccines, you should be given an information sheet summarizing side effects. I recommend getting both vaccines.
Zyrtec D (Cetirizine with Pseudoephedrine) Lexapro (Escitalopram) Yes. They may be taken together if needed.  f you have heart disease or high blood pressure, talk to your doctor before taking any oral decongestant.
Zyrtec D (Cetirizine with Pseudoephedrine) Naproxen (Naprosyn, Aleve) Yes. Take naproxen with milk or food to protect the stomach. Take Zyrtec D as needed for allergies. If you have high blood pressure, talk to your doctor before taking any decongestant (pseudoephedrine).
Zyrtec D (Cetirizine with Pseudoephedrine) Midol Extra Strength Yes. If you have high blood pressure or heart problems, be careful with either of these medications. Pseudoephedrine and caffeine can cause your blood pressure to increase. Take these as needed and with plenty of water.
Zyrtec D (Cetirizine with Pseudoephedrine) Mirapex (Pramipexole) Yes. Take Zyrtec D early in the day, preferably morning. The decongestant in this drug can cause an increased heart rate and can keep you from falling asleep. Drink plenty of water.
Zyrtec D (Cetirizine with Pseudoephedrine) Phentermine (Adipex) Yes. If you have high blood pressure or heart problems, talk with your doctor before taking either of these, as you should avoid decongestants (like pseudoephedrine, phenylephrine, ephedrine) and sympathomimetic stimulants (phentermine).  Both can increase heart rate and constrict blood vessels. Taking both would increase the likelihood of this occurring.
Zyrtec D (Cetirizine with Pseudoephedrine) Prilosec (Omeprazole) Yes.
Zyrtec D (Cetirizine with Pseudoephedrine) Promethazine with Codeine Syrup (Phenergan with Codeine) Zyrtec D and promethazine with codeine both contain anti-histamines. When they are taken together, it increases the risk of drowsiness. Codeine also causes drowsiness. These drugs are often used together. Both should be taken only when needed. Drink plenty of water. Do not drive or operate machinery until you know how these drugs affect you. If you notice slurred speech, confusion, severe weakness or difficulty breathing while taking these drugs, contact your health care provider immediately.
Zyrtec D (Cetirizine with Pseudoephedrine) Robitussin CF Yes. Drink plenty of water with both. If you have high blood pressure or heart problems, do not take either one. Take only as needed.

I have been taking Effexor 150mg, Ziac 2.5/6.25, and pramipexole .25mg. I have concerns that these drugs should not all be taken together. Can they cause symptoms or side effects?
The pramipexole (Mirapex) does not directly interact with either the Effexor or Ziac. Although an interaction is possible, Effexor (venlafaxine) and diuretics, like hydrochlorothiazide (HCTZ) are often used together. Ziac (bisoprolol w/HCTZ) has hydrochlorothiazide. Taking these medicines together may increase the chance of losing sodium from the bloodstream.

I have MS, spinal stenosis, Barrett's esophagus, and bowel disorder. I take Copaxone, Gabapentin/Neurontin, cyclobenzapr/Flexiril, Meclizine, Lasix, Dexilant, Claritin, Ampyra, Murilax, Benicar, Simvastatin, Topamax, Wellbutrin, Lactulose, Linzess, Exlaxative, magnesium citrate, tramadol, Walgreens sleep aid, Arbaclofen, B-12, Biotin, aspirin, vitamin D, vitamin B-12, Conzyme B Complex and Nexium. Thoughts? 
Are all of your physicians aware of what the others are prescribing for you? Has your pharmacist discussed your medication regimen with your physicians? There are many possible drug to drug interactions among all of these medications. I will discuss only a few of the most problematic.

The Wellbutrin (bupropion) has major interaction possibilities with several of the others I realize that you may not be taking the Neurontin gabapentin) or Topamax (topiramate) for seizures or as an anticonvulsant, but it needs to be taken with caution. Do not drive or operate machinery until you know how these drugs affect you. Notify your doctor if you experience confusion, dizziness, falls, mood changes, or other side effects. In addition, the anticonvulsant drugs can reduce the effectiveness of Wellbutrin.

Avoid taking Wellbutrin with Ultram (tramadol) unless no other alternative is better. Wellbutrin may increase the blood levels of tramadol, which may lead to serious side effects. There is an increased risk of seizure taking these two drugs together.

Neurontin should not be taken at the same time as the calcium product. The calcium can block the absorption of the Neurontin. Take the Neurontin at least 2 hours after taking any calcium product.

Normally one would not take diphenhydramine (Benadryl, Walgreen's Sleep Aid) with the meclizine (Antivert). These are both antihistamines and taking both can increase the side effects including dizziness, drowsiness, constipation, dry mouth and eyes, confusion and changes in heart rate.

Many of these medications can cause drowsiness.

Baclofen (Lioresal) can reduce blood pressure. Taking additional blood pressure medications may make you dizzy and prone to falls.

Do not take multiple laxatives in the same day without direction of the physician. The laxatives may interfere with the actions of the Lactulose.

It sounds like you are being pro-active on your medication therapy and have a good relationship with your local pharmacist. This is wonderful. Any time your doctors add or subtract from your medications, please discuss with your pharmacist.

Can I take Biaxin and Buscopan together?
Buscopan is a form of hyoscine (butylbromide) made in Germany and available in many countries throughout the world. It is a similar product scopolamine (l-hyoscine), an alkaloid found in belladonna. Buscopan is not approved by the FDA in the United States. It also appears to be similar to hyoscyamine (Levsin), which is an American product. They are both indicated the same conditions. There are no direct drug interactions between Biaxin (clarithromycin) and hyoscyamine or scopolamine. I would surmise that this would hold true for Buscopan also. Take the Biaxin as prescribed until finished. Use the Buscopan as needed.

Can I take bupropion xl with mometasone furoate inhaler? Also, can bupropion be used for 7 days along with nicotine until quit date? Finally, can a nicotine patch be used with bupropion?
Although an interaction is possible, mometasone (Asmanex) and bupropion (Wellbutrin XL) are often used together without problems. The inhaled steroid products usually do not cause many problems even though the oral steroids can. Many times, doctors will have people use both the bupropion and nicotine patches together for a short while. People do start the bupropion before completely weening off the tobacco, but in some people, the combination of bupropion (either Wellbutrin or Zyban) with nicotine may cause increased blood pressure. Have your blood pressure monitored regularly while taking these two drugs together.

Can Alka-Seltzer Plus and Afrin nasal spray be used together?
There can be a drug interaction between Alka-Seltzer Plus Cold and any medication like the decongestant found in Afrin (oxymetazoline). If you have high blood pressure or heart disease, please speak to your physician before using any decongestant. Both of these products are or have nasal decongestants. Using them together can increase the risk of high blood pressure, nervousness, palpitations, problems with sleep, or other serious side effects. An alternative to the Afrin would be a saline nasal spray. If you do use the Afrin, limit using this for not more than 3 to 5 days, up to twice daily.

Can I take Advil Cold and Sinus with Cheratussin AC?
There are no direct drug interactions between Advil Cold and Sinus (ibuprofen, pseudoephedrine) and Cheratussin AC (guaifenesin, codeine).

I take Claritin 24 Hour, metformin, medroxyprogesterone, One-A-Day women's multi-vitamin, ibuprofen when needed, Vitamin C, an albuterol inhaler and stool softer. Can I take with Nyquil and Dayquil?
The Vicks Nyquil and DayQuil both can interact with the albuterol although less with the inhaled than with the oral albuterol products. Both may also interact with metformin (Glucophage) by interfering with the action of the metformin. If you use a blood sugar monitoring device at home, check your blood sugar regularly while taking these medicines together. The metformin may also interact with some vitamins. I would suggest taking the One-A-Day vitamin an hour before at least two hours after metformin. The Nyquil and Claritin (loratadine) both have antihistamines. Generally, if you take the Claritin early in the morning and Nyquil at bedtime, the drowsiness side effects may not be a problem. The metformin may also interact with medroxyprogesterone (Provera). Although an interaction is possible, these drugs are often used together. Monitor your blood sugar. The Vitamin C is fine with any of the others. I would suggest avoiding the Vicks products if possible.

Can you take Tylenol or ibuprofen to help reduce fever while already using Alka-Seltzer Plus Max for cough, mucus and congestion?
If you have the Alka-Seltzer product that contains dextromethorphan (DM) and guaifenesin (Mucinex or Robitussin) you may take either Tylenol (acetaminophen) or ibuprofen (Advil or Motrin) for fever or pain. There are many different types of Alka-Seltzer and some do contain either aspirin or acetaminophen. Please be sure to read the ingredients on the box.

Can I take phentermine if I wear Butran patch?
There are no direct drug interactions between Butrans (buprenorphine) patch and phentermine (Adipex).

Can I take both Coricidin and Flonase together?
There are no direct drug interactions between Coricidin (chlorpheniramine, pseudoephedrine) and Flonase (fluticasone).

Can I take amlodipine, losartan and Allegra together?
There is a slight drug interaction between the amlodipine (Norvasc) and losartan (Cozaar), but frequently multiple drugs are used to treat hypertension, so the individual doses can be smaller. Although an interaction is possible, these drugs may be used together. The Allegra (fexofenadine) does not interact directly with either of the other two.

My mother took Adipex, lisinopril and Coreg which has her feeling weird. Can she Geodon and half a Xanax like she does every night?
There are some interactions between several of these medications. Does the same doctor prescribe all of these? If not, do all the doctors have a current medication list for your mother? First: The Adipex (phentermine), a sympathomimetic drug, can interact with the Coreg (carvedilol) a beta blocker. The Coreg and lisinopril (Zestril) also can interact with the Geodon (ziprasidone). The Xanax (alprazolam) can also cause extra drowsiness with Geodon. Although an interaction is possible, these drugs are sometimes used together with caution. Do not change the dosing times unless instructed by her doctor. If you have any questions about timing, please contact her doctor.

I am taking Xyzal for allergies was also prescribed Valium. I am an adult and want to know If I can take these on the same day or together? Also, also can I drink with Xyzal?
There are not any true drug interactions between Xyzal (levocetirizine) and Valium (diazepam) but there may be an increased likelihood of side effects. You may feel drowsy or more tired when taking these drugs together. Do not drive or operate machinery until you know how these drugs affect you. Adding alcohol to the mix will definitely increase the sedation effects. Please do not plan to drive after drinking.

I am currently taking Benicar HCT 11.5mg, Lamictal 150 mg, Pristiq 50 mg and Vyvanse 60 mg. Is this cocktail safe? All are prescribed by psychiatrist other than the Benicar.
Technically, all the medications that your psychiatrist has ordered: Lamictal (lamotrigine), Pristiq (desvenlafaxine) and Vyvanse (lisdexamfetamine) can all have interactions with each other. In reality, many psychiatrist's prescribe multiple medications to keep the doses lower. Be sure that all of your health care providers have a current list of your medications, including OTC products, vitamins and herbals. If you have any concerns, please contact your physician.

Should I take hydrocodone or a tramadol with Flexeril?
The Flexeril (cyclobenzaprine), a muscle relaxant, can interact with either of the other two pain medications. Hydrocodone is available only in combination with acetaminophen (Tylenol) with brand names Norco, Vicodin or Lortab. The Flexeril can cause drowsiness as well as the tramadol (Ultram) and hydrocodone products. The interaction is due to increasing the chance and severity of side effects. You may feel drowsy or more tired when taking these drugs together.

I take 6 butalbital a day. Is it safe to take 50 milligram of Pristiq a day also?
Normally butalbital is combined with acetaminophen (Tylenol). There are no direct drug interactions between Pristiq (desvenlafaxine) and butalbital or acetaminophen.

Can I take atenolol, diazepam and Robitussin PM?
There are no direct drug interactions between atenolol (Tenormin), diazepam (Valium) and Robitussin DM (guaifenesin w/dextromethorphan).

The montelukast (Singulair) does not interact with either the Vicks Nyquil (acetaminophen, dextromethorphan, doxylamine & doxylamine) or Symbicort (budesonide, formoterol). The Vicks Nyquil product can interact with the inhaled Symbicort because of additive side effects that may occur.

Can I take pantoprazole and phentermine?
There are no direct drug interactions between pantoprazole (Protonix) and phentermine (Adipex). They may be taken together if needed.

I took Tussin DM. When can I take venlafaxine again?
There are no direct drug interactions between Tussin DM (guaifenesin w/dextromethorphan) and venlafaxine (Effexor). They may be taken together if needed.

I took a .05mg lorazepam this morning for anxiety. Can I take a 5mg Valium now?
Both lorazepam (Ativan) and Valium (diazepam) are classified as benzodiazepines. These are controlled drugs used for anxiety disorders as well as other indications. The Valium is a longer acting medication. Generally these medications are not used together. Do not take lorazepam and other drugs for anxiety, sleep or nerves together without talking to your health care provider. If you notice slurred speech, confusion, severe weakness, or difficulty breathing, contact your health care provider immediately.

I currently take Celexa, Inderal and Unisom. Can I take Adipex with these?
Are you seeing more than one physician? If so, be sure that all have a current medication list for you and keep it updated with any changes. Yes there can be a problem adding Adipex (phentermine) to the others. Do not take the Celexa (citalopram) with Adipex together without talking to your health care provider. The combination may increase the risk of confusion, increased blood pressure or heart rate, loss of coordination, restlessness, sweating, tremor, vomiting, or other serious side effects. Taking Inderal (propranolol), a beta blocker, with Adipex can cause chest pain, high blood pressure, increased heart rate or other heart-related side effects in persons predisposed to these conditions, which may make the beta-blocker-type drug less effective at treating heart or blood pressure related problems.

Can you take Bactrim with azithromycin?
Both Bactrim (sulfamethoxazole w/trimethoprim) and azithromycin (Zithromax) are antibiotics. They work differently and have different spectrum of activities against bacteria. Even so, these drugs may be taken together only under close supervision from your prescriber.

Can you take cephalexin for a staff infection and take loratadine for sinus and Tums together?
There are no direct drug interactions between cephalexin (Keflex), Tums (calcium carbonate) and loratadine (Claritin).

Can taking Paxil and oxycodone cause low blood pressure?
There is a potential chance of drug serious interactions between Paxil (paroxetine) and oxycodone (Oxycontin). The likelihood of an interaction is higher if oxycodone is used on a regular basis (daily). Contact your health care provider immediately if you develop nausea, vomiting, excessive sleepiness or sedation, dizziness, excessive sweating, facial flushing, confusion, jerking or twitching of muscles, increased blood pressure, restlessness, or shivering. If you notice a problem, please contact your physician right away.

If I am taking a small dose of metoprolol and using a daily inhaler, is it safe to take phentermine?
Please speak to your cardiologist or primary doctor before taking the phentermine (Adipex). Adipex can increase your heart rate which may cause problems with the metoprolol (Toprol or Lopressor). Some asthma inhalers may also increase your heart rate, so please speak to your doctor or doctors before taking any stimulant product like phentermine.

Can I take Robitussin Nasal Relief and albuterol together?
There is a possible drug interaction between the Robitussin product (guaifenesin, acetaminophen and phenylephrine) and albuterol (Ventolin, Proventil, Pro-Air). Taking an oral decongestant like phenylephrine or Sudafed (pseudoephedrine) with the albuterol can increase the risk of a fast heart rate, nervousness, palpitations, problems with sleep, or other side effects. I would suggest speaking to your physician before using any oral decongestant product, especially if you have high blood pressure.

Is it OK to take Dilantin while drinking promethazine DM?
I hope you meant that you are taking a teaspoonful or two of promethazine DM (Phenergan DM). There is a slight interaction between the Dilantin (phenytoin) and promethazine. This can occur with Dilantin and any sedating antihistamine product. You may feel drowsy or more tired when taking Phenytoin antihistamines together.

Can I take Zoloft, Klonopin and Cheratussin AC together?
Cheratussin AC (guaifenesin w/codeine) can interact with both the Zoloft (sertraline) and the Klonopin (clonazepam). You may feel drowsy or more tired when taking these drugs together. This effect may last for a few days after you stop taking these drugs together. Do not drive or operate machinery until you know how these drugs affect you. If you notice slurred speech, confusion, severe weakness, or difficulty breathing, contact your health care provider immediately.

There are several formulations for Coricidin HBP. The various ingredients include: acetaminophen, chlorpheniramine, dextromethorphan and or guaifenesin. The Celebrex (celecoxib) can interact with the dextromethorphan (DM) by increasing the risk of side effects of the DM.

I am taking Wellbutrin, Fluoxetine and simvastatin. Can I take Percocet too?
There is a possible drug interaction between Percocet (oxycodone w/acetaminophen) and both Wellbutrin (bupropion) and fluoxetine (Prozac). Side effects from Percocet may get worse if you take Wellbutrin and/or fluoxetine.

While there are no direct drug interactions between Adipex (phentermine), amlodipine (Norvasc) and triamterene w/HCTZ (Maxzide or Dyazide), I would not consider it a wise choice to make if you have high blood pressure or heart disease. Adverse reactions to Adipex include
hypertension, angina, syncope and edema.

What will happen if someone takes five Aleve and 300mg of Wellbutrin together?
There are no direct drug interactions between Aleve (naproxen) and Wellbutrin (bupropion). The side effects generally involve GI symptoms, the most severe would be risk of drug-induced stomach bleeding.

Is it safe to take methylprednisolone while taking Effexor, Trazodone and clonazepam?
The methylprednisolone (Medrol) does not have any direct drug interactions with the other medications. Normally the methylprednisolone is taken in the mornings with food. There are possible drug interactions among the other medications. Trazodone (Desyrel) can interact with both the Effexor (venlafaxine) and clonazepam (Klonopin). Trazodone and Effexor may represent duplicate therapies for mood problems like depression in some patients and are not commonly prescribed together. If these drugs are used together, do so with caution. Side effects from Effexor may potentially get worse if you take trazodone. Taking these drugs together could result in side effects such as chest pain, chest tightness or pressure, confusion, dizziness, drowsiness, excessive dry mouth, excessive nausea and vomiting, fever, loss of coordination, muscle twitching or weakness, sweating, tremor, and/or palpitations.

Can I take Zyrtec D while using albuterol?
Taking pseudoephedrine (Sudafed) with albuterol can increase the risk of a fast heart rate, nervousness, palpitations, problems with sleep, or other side effects. Speak to your physician before using any oral decongestant. Using plain Zyrtec will not have any interaction with albuterol.

There is a possible drug interaction between the lisinopril (Zestril or Prinivil) and the Janumet combination drug (metformin with sitagliptin). Although an interaction is possible, these types of medications are often used together. The Zyrtec (cetirizine) and Paxil (paroxetine) may be taken with any of the others. If your doctor told you to take the Janumet separate from the rest and you do check your blood sugars, have a talk with them about taking your medications together with breakfast.

I'm taking Percocet 10/325 and Neurontin 300mg. Can I take NyQuil?
There is a chance of interaction between the Percocet (oxycodone w/acetaminophen) and Nyquil. You may feel drowsy or more tired when taking these drugs together.

Is it safe to take Zoloft, Valium, Adipex, Amoxicillin, metformin and HCTZ without any interactions?
There can be several drug interactions within this group of medications. Do not take the Adipex (phentermine) and Zoloft (sertraline) together without talking to your health care provider. Taking the Zoloft with Valium (diazepam) could be a problem also because the Zoloft can theoretically decrease the elimination of Valium from the body. The metformin (Glucophage) may possibly interact with both the HCTZ (hydrochlorothiazide) and the Adipex. The Adipex and HCTZ may decrease the actions of metformin by increasing the blood sugar. These drugs are often used together. The amoxicillin is OK to take with any or all of the others. Please be sure that all of your health care providers have a current list of all your medications. Take the list with you every time you see the doctor.

Can Adderall be taken with atenolol?
Do not take atenolol (Tenormin),a Beta-blocker, and Adderall (mixed amphetamine salts) together without talking to your health care professional first.

Can I take echinacea, Klonopin, Zoloft and propranolol?
These may all be taken together if needed. There is a chance for increased drowsiness, so be careful when you must be alert. Is it OK to be on the following medications all at once: Cymbalta, Statex, clonazepam, topiramate and risperidone?
There are several interaction possibilities when taking Cymbalta (duloxetine), Statex (morphine), clonazepam (Klonopin), topiramate (Topamax) and risperidone (Risperdal). Have all of these medications been prescribed by the same physician? If not, be sure all your health care providers are aware of your medications. Cymbalta and risperidone should not be taken together without speaking to your physicians first. Clonazepam and topiramate are often used together with close monitoring by your health care provider. Topiramate may decrease the actions of risperidone. Your physician(s) and pharmacist should have discussed these issues with you when these were prescribed.

I'm taking tramadol/acetaminophen for pain. Can I take Tums for acid relief?
There are no direct drug interactions between tramadol/acetaminophen (Ultracet) and Tums (calcium carbonate).

I was prescribed Adderall, Prozac, trazodone, Klonopin, doxycycline, and hydrocodone. Are these safe to take together?
There may be several interactions. Adderall and Klonopin are not commonly prescribed together. If you are taking the Klonopin for seizures, these amphetamines may decrease the effectiveness of anticonvulsants (when used for treating seizures) by lowering the threshold for seizures. The Prozac may interact with both Adderall and trazodone. In general, do not take trazodone and Prozac. These two represent duplicate therapies for mood problems like depression in some patients and are not commonly prescribed together. If these drugs are used together, do so with caution. Taking the hydrocodone with any other drugs that may cause drowsiness, can intensify this side effect. The same holds true for the Klonopin. Doxycycline can be taken with any of the others without problem.

Can I take cephalexin 500mg while using the Butrans Patch?
There are no direct drug interactions between cephalexin (Keflex) and Butrans (buprenorphine) Patch.

The risperidone may also interact with divalproex and cause excess drowsiness. Doxycycline (Vibramycin) does not interact with any of the others.

Can I take pramipexole .125mg, Xanax.25 mg and Allegra D together?
There can be an interaction between the pramipexole (Mirapex) and Xanax (alprazolam). You may feel drowsy or more tired when taking these drugs together. The Allegra D (fexofenadine with pseudoephedrine) does not interact with either of the others, though if you have high blood pressure or heart disease, please speak to your doctor before taking any oral decongestant.

Can I take ProAir with Celexa?
There can be a serious drug interaction with ProAir (albuterol) and Celexa (citalopram). Do not take these medicines together without approval from your doctor.

Can you take hydrochlorothiazide and topiramate together?
There can be a drug interaction between hydrochlorothiazide (HCTZ) and topiramate (Topamax). Side effects from topiramate may get worse if you take HCTZ. Discuss any new or worsening side effects such as fatigue, nervousness, difficulty concentrating, confusion, depression, decreased appetite, language problems, anxiety, moodiness, weight loss, or tremor with your health care provider. Do not stop taking HCTZ without talking with your doctor.

I am currently taking Zoloft and Ativan. Can I take herbal formula colon cleanse with these?

Are there any serious interactions if I take Prozac, Wellbutrin, Venlafaxine, Trazodone, Mirapex, Pradaxa and flecainide together?
Yes. All these drugs interact with one another. Talk to your doctor.

Can I take hydrocodone while taking Effexor and clonazepam?
There is a possible interaction, an increased chance of side effects, with two of these medications. The hydrocodone (Norco, Vicodin, Lortab) can interact with clonazepam (Klonopin). You may feel drowsy or more tired when taking these drugs together.

My 78-year-old mother is taking amlodipine and Vesicare together. Is this OK?
Yes. Try not to miss any doses and take them the same times each day.

I take atenolol, clonazepam and use Flonase. I feel tired and dizzy almost every day. Is there an allergy medication that is safe to use with all these other medicines? I have an enlarged prostate so cannot take Benadryl.
There are no direct drug interactions between these and any of the common long acting antihistamine products. The long acting, non-sedating antihistamines like Allegra, Zyrtec or Claritin do not have the warning regarding the prostate issue. Speak to your physician before trying any new medications.

I currently take albuterol sulfate, prednisone, cefuroxime and Mucinex. Can I take Flexeril?
There is one very infrequent possible side effect, when you add Flexeril (cyclobenzaprine) to this list of medications. But it can be a bad one. Although rare, Flexeril can increase the risk of a dangerous change in heartbeat or heart rhythm. Seek medical attention immediately if you notice side effects like chest pain, dizziness, fainting or falling spells, palpitations, shortness of breath, or a change in your heart beat.

Can I take Mobic, Prilosec, Flexeril, tramadol and azithromycin?
Talk to your doctor. Although very rare, taking azithromycin and Flexeril together together can increase the risk of a dangerous change in heartbeat or heart rhythm. Flexeril can interact or have an increased chance of side effects with tramadol. You may feel drowsy or more tired when taking these drugs together. Also there is a slight chance the azithromycin and the Prilosec taken together may have an increase in side effects they may cause.

Is it safe to take minocycline 100mg and take Buckley's Complete liquid gels with daytime mucous relief?
Yes. Avoid milk and dairy products with the minocycline and always use sun screen when outdoors.

Can I use Adacin Gel and loratadine tablets at the same time?
Yes. It is rare when a topical product truly interacts with an oral drug. When using Adacin Gel, protect your skin from the sun as it can make it easier to burn.

I am starting amitriptyline. Will it be OK to take with levothyroxine?
The levothyroxine (Synthroid) is normally taken in the morning before breakfast. The amitriptyline (Elavil) is taken at bedtime. There is a slight risk of interaction, but if the doses are separated, the chances are greatly reduced.

What are the risks of taking Celebrex, Prozac and tramadol together?
The issues with these medications are due to Prozac. Taking Prozac and tramadol may increase the risk of serious side effects. Celebrex can irritate the stomach lining and Prozac can increase the risk of this happening.

Can I take levothyroxine, primidone (50mg), amlodipine (2.5 mg) and red rice yeast at the same time?
The primidone may interact with the other three medications. Primidone can affect the actions of amlodipine on blood pressure. The primidone also may decrease the actions of levothyroxine and red yeast rice. Discuss your drug regimen and dietary supplements with your health care provider. Your health care provider should monitor your thyroid function as needed. The other three drugs do not interact with one another.

Can I take Buspar 15mg, Wellbutrin 200mg and Cymbalta 60mg together?
The Buspar (buspirone) and Cymbalta (Duloxetine) can be a problem. This combination may increase the risk of confusion, increased blood pressure or heart rate, loss of coordination, restlessness, sweating, tremor, vomiting, or other side effects. The Wellbutrin (bupropion) does not interact with the other two but is an antidepressant along with the Cymbalta. These would be considered a duplication of therapy. Contact your doctor to discuss these possible problems.

My doctor has me on Adipex, Klonopin and Ambien. Is it OK to take all of them?
The Klonopin (clonazepam) and Ambien (zolpidem) do interact. Do not take drugs for anxiety, sleep or nerves together without talking to your health care provider. Some medications can be similar or duplicate treatments.

Can you take Pyridium and penicillin together?
Yes. Drink plenty of fluids with this. Take the penicillin until complete or as directed.

Can I take Coricidin and topiramate?
Yes. If you have heart disease or high blood pressure, use the Coricidin HBP formula. This does not have an oral decongestant. The main side effect of these is drowsiness or headaches.

Can you take IophenC, trazodone, Lamictal and Depakote?
There are a couple of possible drug interactions. You may feel drowsy or more tired when taking these drugs together. DO NOT change your medicines without talking to your prescriber. If you experience a seizure, or have new or unusual side effects such as chest pain, dizziness, unsteadiness when you walk, skin rash, tremors or nausea and vomiting, contact your health care provider immediately. Take the cough syrup only as needed, with plenty of water.

Can I take one bupropion HCL SR 150mg and 2mg estradiol at 5:30 a.m. then go back to bed and take Fosamax 70mg at 9:00 a.m. without lessening absorption rate of any of them?
There are no direct drug interactions between bupropion (Wellbutrin), estradiol (Estrace) and Fosamax (alendronate). According to the manufacturer and FDA recommendations, Fosamax should be taken before any other medication in the morning, at least by 30 minutes. I would suggest having a discussion with your physicians about the timing you take your medications. I would think that a greater than three hour period of time between the others before taking the Fosamax, would be enough to avoid any issues.

My daughter's doctor prescribed Topamax and Neurontin. He then added risperidone. Is this a safe combination? She is 24 and about 128 pounds.
There are two possible drug interactions. Neurontin (gabapentin) has no direct drug interactions with the other three. There is a minor interaction between risperidone (Risperdal) and Topamax (topiramate). There may be an increase in the risk of drowsiness, increased blood pressure or heart rate, loss of coordination, restlessness, sweating, vomiting, or other side effects.

Can you take Flexeril if you are allergic to codeine and penicillin?
Yes. There is no cross sensitivity if you are allergic to codeine and penicillin with Flexeril (cyclobenzaprine).

Can I take Atarax, Keflex and Medrol at the same time?
Yes. They may be taken together if needed. Normally Medrol is given after a meal in the morning, Keflex could be taken with or without food and Atarax should be taken as needed.

Can I take hydroxyzine 25mg with atenolol?
Yes. There are no direct drug interactions between hydroxyzine (Atarax) and atenolol (Tenormin).

I take hydrochlorothiazide 50mg, lisinopril 10mg, Norco 10/325mg in the morning, Norcos every 6 hours and cyclobenzaprine hcl 10mg three times a day. Now my doctor wants me to take citalopram hydrobromide 20mg. Is it safe?
There are drug interactions with citalopram (Celexa) and both the cyclobenzaprine (Flexeril) and the Norco (hydrocodone with acetaminophen). In particular, do not take citalopram and cyclobenzaprine together without approval from your prescriber. If you take these drugs together, you have an increased chance of developing a dangerous change in heartbeat or heart rhythm. Norco, when taken with citalopram and/or Norco, may make you feel drowsy or more tired. There is a minor chance of a drug interaction between the hydrochlorothiazide (HCTZ) and lisinopril (Zestril). If your blood pressure drops too low, you may become dizzy or feel faint. If the same doctor is prescribing all of these drugs, these problems should have been discussed with you.

Can I take Allegra with Prilosec? I am having lots of acid reflux. Should I take Sudafed since I am having a lot of nasal drip?
Yes. If you have high blood pressure or heart disease, talk to your doctor before taking any oral decongestants, like Sudafed.

Can I take doxycycline 100mg and Voltaren 100mg, twice a day?
Yes. They may be taken together if necessary, but it is preferred to take the doxycycline on an empty stomach at least an hour away from antacids, vitamins or proton pump inhibitor drugs like Protonix. Take Voltaren with food or milk to prevent stomach upset.

Can I take Flexeril with hydroxyzine and fluoxetine?
There are interactions between Flexeril (cyclobenzaprine) and both the hydroxyzine (Atarax) and fluoxetine (Prozac). Do not take both Flexeril and fluoxetine without talking with your doctor. If your doctor wants you to take both drugs, immediately report any unusual effects such as sweating, nausea, confusion, palpitations, or tremors. If you have to take both the Flexeril and hydroxyzine, you may feel drowsy or more tired when taking these drugs together. If you notice slurred speech, confusion, severe weakness, or difficulty breathing, contact your health care provider immediately.
