Before using this medication, tell your doctor or pharmacist of all prescription and nonprescription/herbal products you may use, especially of: anticholinergic drugs (e.g., atropine, belladonna alkaloids, scopolamine), certain anti-Parkinson's drugs (e.g., benztropine, trihexyphenidyl), anti-platelet drugs (e.g., clopidogrel), "blood thinners" (e.g., heparin, warfarin), bisphosphonates taken by mouth (e.g., alendronate), carbonic anhydrase inhibitors (e.g., acetazolamide), cimetidine, corticosteroids (e.g., prednisone), cyclosporine, drugs for diabetes (e.g., insulin, sulfonylureas such as glipizide), drugs for gout (e.g., probenecid, sulfinpyrazone), drugs for high blood pressure (e.g., ACE inhibitors such as captopril/lisinopril, angiotensin II receptor blockers such as as losartan, and beta blockers such as metoprolol), drugs that change the acidity of urine (e.g., antacids, citrates, sodium bicarbonate, high doses of vitamin C/ascorbic acid), ginkgo biloba, lithium, methotrexate, narcotic agonist/antagonists (e.g., butorphanol, nalbuphine), NSAIDs and other salicylates (e.g., ibuprofen, naproxen, salsalate), pemetrexed, potassium tablets/capsules, quinidine, SSRI antidepressants (e.g., fluoxetine, paroxetine), "water pills" (diuretics such as furosemide, hydrochlorothiazide).

Tell your doctor or pharmacist if you also take drugs that cause drowsiness such as: certain antihistamines (e.g., diphenhydramine), anti-seizure drugs (e.g., carbamazepine), medicine for sleep or anxiety (e.g., alprazolam, diazepam, zolpidem), muscle relaxants, narcotic pain relievers (e.g., hydrocodone, propoxyphene), psychiatric medicines (e.g., chlorpromazine, risperidone, amitriptyline, trazodone). Check the labels on all your medicines (e.g., cough-and-cold products) because they may contain ingredients that cause drowsiness. Alcoholic beverages will also increase the drowsiness effect. Ask your pharmacist about using those products safely.

Check all prescription and nonprescription medicine labels carefully since many contain pain relievers/fever reducers (NSAIDs such as ibuprofen, naproxen, or aspirin) that are similar to this drug. Low-dose aspirin should be continued if prescribed by your doctor for heart attack or stroke prevention (usually at dosages of 81-325 milligrams a day). Consult your doctor or pharmacist for more details.
