GENERIC NAME: NAPROXEN ENTERIC-COATED TABLET - ORAL (nah-PROX-en)

BRAND NAME(S): EC-Naprosyn

WARNING: This drug may infrequently cause serious (rarely fatal) bleeding from the stomach or intestines. This side effect can occur without warning at any time during treatment with naproxen. The elderly are at increased risk for serious stomach/intestinal bleeding.

Drugs related to naproxen have rarely caused blood clots to form, resulting in serious (possibly fatal) heart attacks and strokes. This medication might also rarely cause similar problems. The risk of these serious side effects may increase if you have heart disease and with longer use of this medication. Talk to your doctor or pharmacist about the benefits and risks of treatment, as well as other possible medication choices.

Stop taking naproxen and seek immediate medical attention if you notice any of the following rare but very serious side effects: black stools, persistent stomach/abdominal pain, vomit that looks like coffee grounds, chest pain, shortness of breath, weakness on one side of the body, sudden vision changes, slurred speech.

This medication should not be used right before or after heart bypass surgery.

USES: Naproxen is used to relieve mild to moderate pain from various conditions. It reduces pain, swelling, and joint stiffness caused by arthritis. Reducing these symptoms helps you do more of your normal daily activities. This medication is known as a nonsteroidal anti-inflammatory drug (NSAID).Enteric-coated tablets of naproxen are absorbed more slowly into your bloodstream than other forms of naproxen. Therefore, they should not be taken to relieve sudden pain (e.g., from gout attacks, menstrual pain, tendonitis, bursitis). Ask your doctor or pharmacist about other medications that can quickly relieve sudden pain from these conditions.

HOW TO USE: Read the Medication Guide provided by your pharmacist before you start using naproxen and each time you get a refill. If you have any questions regarding the information, consult your doctor or pharmacist.Take this medication by mouth, usually twice daily with or without food. Swallow this medication whole. Do not break, crush, or chew the tablets. Doing so can destroy the enteric coating of the drug and cause the medication to be released too quickly, possibly increasing side effects. Take this medication with a full glass of water (8 ounces or 240 milliliters) unless your doctor directs you otherwise. Do not lie down for at least 30 minutes after taking this drug.Do not take this medication with antacids or other drugs that decrease stomach acid. (For more information, see Drug Interactions.)Dosage is based on your medical condition and response to therapy. Do not take more than 1,500 milligrams per day. To minimize side effect risks (e.g., stomach bleeding), use this medication at the lowest effective dose for the shortest possible length of time. Do not increase your dose or take it more often than prescribed. For ongoing conditions such as arthritis, continue taking it as directed by your doctor. Discuss the risks and benefits with your doctor or pharmacist.In certain conditions (e.g., arthritis), it may take up to 2 weeks of regular use before the full benefits of this drug take effect.Inform your doctor if your condition worsens.

If any of these effects persist or worsen, notify your doctor or pharmacist promptly.Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.Tell your doctor immediately if any of these unlikely but serious side effects occur: stomach pain, swelling of the hands/feet, sudden/unexplained weight gain, vision changes, hearing changes (e.g., ringing in the ears), mental/mood changes (e.g., depression), fast/pounding heartbeat, persistent/severe headache, fainting, difficult/painful swallowing.Tell your doctor immediately if any of these rare but very serious side effects occur: change in the amount of urine, easy bruising/bleeding, signs of infection (e.g., fever, persistent sore throat), unexplained stiff neck.This drug may rarely cause serious (possibly fatal) liver disease.

Consult your doctor or pharmacist for more information.This medication may make you more sensitive to the sun. Avoid prolonged sun exposure, tanning booths, and sunlamps. Use a sunscreen and wear protective clothing when outdoors.The elderly may be more sensitive to the side effects of this drug, especially stomach/intestinal bleeding and kidney effects.This medication should be used only when clearly needed during the first 6 months of pregnancy.

DRUG INTERACTIONS: Your healthcare professionals (e.g., doctor or pharmacist) may already be aware of any possible drug interactions and may be monitoring you for it. 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: high doses of aspirin and related drugs (salicylates), cidofovir, other NSAIDs (e.g., ketorolac).If you are currently using any of these medications listed above, tell your doctor or pharmacist before starting naproxen.Stomach/ulcer medications that work by lowering the amount of stomach acid should not be taken with enteric-coated naproxen. They may break down the enteric coating and cause the medication to be released too quickly. Tell your doctor or pharmacist if you use any of the following medications: antacids, H2-blockers (e.g., famotidine, ranitidine), proton pump inhibitors (e.g., lansoprazole, omeprazole), sucralfate.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), oral bisphosphonates (e.g., alendronate), "blood thinners" (e.g., enoxaparin, heparin, warfarin), corticosteroids (e.g., prednisone), cyclosporine, desmopressin, digoxin, high blood pressure drugs (including ACE inhibitors such as captopril, angiotensin receptor blockers such as losartan, and beta-blockers such as metoprolol), lithium, methotrexate, pemetrexed, probenecid, SSRI antidepressants (e.g., fluoxetine, sertraline), "water pills" (diuretics such as furosemide, hydrochlorothiazide, triamterene).Check all prescription and nonprescription medicine labels carefully for other pain/fever drugs (NSAIDs such as aspirin, celecoxib, ibuprofen). These drugs are similar to this medication, 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.This medication can affect the results of certain lab tests. Make sure laboratory personnel and your doctors know you use this drug.This document does not contain all possible interactions.
