lansoprazole and naproxen - oral, Prevacid Naprapac (cont.)
DRUG INTERACTIONS: Your doctor or pharmacist may already be aware of any possible drug interactions and may be monitoring you for them. Do not start, stop, or change the dosage of any medicine before checking with them first.This drug should not be used with the following medications because very serious interactions may occur: atazanavir, cidofovir, nelfinavir, pemetrexed.If you are currently using any of these medications, tell your doctor or pharmacist before starting lansoprazole and naproxen.Before using this medication, tell your doctor or pharmacist of all prescription and nonprescription/herbal products you may use, especially of: anti-platelet drugs (e.g., cilostazol, clopidogrel), alendronate, other medications for arthritis (e.g., aspirin, methotrexate), "blood thinners" (e.g., warfarin, enoxaparin, heparin), cilostazol, corticosteroids (e.g., prednisone), cyclosporine, desmopressin, high blood pressure drugs (including ACE inhibitors such as captopril, angiotensin II receptor antagonists such as losartan, and beta-blockers such as metoprolol), lithium, other NSAIDs (e.g., ibuprofen, celecoxib), probenecid, SSRI antidepressants (e.g., fluoxetine, sertraline), theophylline, voriconazole, "water pills" (diuretics such as furosemide, hydrochlorothiazide, triamterene).Some products need stomach acid so that the body can absorb them properly (such as ampicillin, iron supplements, calcium supplements, dasatinib, azole antifungals including ketoconazole). Lansoprazole decreases stomach acid, so it may change how well these other products work. Before using lansoprazole, consult your doctor or pharmacist about the other medications you take and for advice on how to reduce or avoid these types of interactions.Based on information for similar drugs, lansoprazole may increase the amount of digoxin that is absorbed into your blood. Consult your doctor or pharmacist for details if you also take digoxin.This product can affect the results of certain lab tests. Make sure laboratory personnel and your doctors know you use this drug.Check all prescription and nonprescription medicine labels carefully for other pain/fever drugs (NSAIDs such as aspirin, celecoxib, ibuprofen). These drugs are similar to naproxen, so taking one of these drugs while also taking this medication may increase your risk of side effects. However, if your doctor has prescribed low doses of aspirin to prevent heart attack or stroke (usually at dosages of 81-325 milligrams a day), you should continue to take the aspirin. Daily use of NSAIDs (e.g., ibuprofen) may decrease aspirin's ability to prevent heart attack/stroke. Consult your doctor or pharmacist for more details and to discuss other possible treatments (e.g., acetaminophen) for your pain/fever.Do not take this medication with any other medications that contain naproxen.This document does not contain all possible interactions. Therefore, before using this product, tell your doctor or pharmacist of all the products you use. Keep a list of all your medications with you, and share the list with your doctor and pharmacist.
