Naproxen is a nonsteroidal anti-inflammatory drug (NSAID). It may cause an increased risk of serious and sometimes fatal heart and blood vessel problems (eg, heart attack, stroke).

    How to use Naproxen

    Use Naproxen as directed by your doctor. Check the label on the medicine for exact dosing instructions.

    Naproxen comes with an extra patient information sheet called a Medication Guide. Read it carefully. Read it again each time you get Naproxen refilled.

    Take Naproxen by mouth. It may be taken with food if it upsets your stomach. Taking it with food may not lower the risk of stomach or bowel problems (eg, bleeding, ulcers). Talk with your doctor or pharmacist if you have persistent stomach upset.

    Take this medicine with a full glass of water (8 oz/240 mL) as directed by your doctor. If you take antacids, cholestyramine, or sucralfate, ask your doctor or pharmacist how to take them with Naproxen.

    Safety Information About Naproxen

    Naproxen may cause dizziness or drowsiness. These effects may be worse if you take it with alcohol or certain medicines. Use Naproxen with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.

    Serious stomach ulcers or bleeding can occur with the use of Naproxen. Taking it in high doses or for a long time, smoking, or drinking alcohol increases the risk of these side effects. Taking Naproxen with food will NOT reduce the risk of these effects. Contact your doctor or emergency room at once if you develop:

    • severe stomach or back pain
    • black, tarry stools
    • vomit that looks like blood or coffee grounds
    • unusual weight gain or swelling.

    Talk to your doctor before you take Naproxen if you drink more than 3 drinks with alcohol per day. If you have pain that does not get better within 10 days or fever that does not get better within 3 days, check with your doctor. If your symptoms get worse or if you have new symptoms, check with your doctor.

    Do NOT take more than the recommended dose or use for longer than 10 days without checking with your doctor. Contact your doctor if you have trouble swallowing, severe or persistent heartburn, or if it feels like the tablet is stuck in your throat.

    Naproxen has naproxen in it. Before you start any new medicine, check the label to see if it has naproxen or any other NSAID (eg, ibuprofen) in it too. If it does or if you are not sure, check with your doctor or pharmacist. Do not take aspirin while you are using Naproxen unless your doctor tells you to. Naproxen may interfere with certain lab tests. Be sure your doctor and lab personnel know that you take Naproxen.

    Use Naproxen with caution in the ELDERLY; they may be more sensitive to its effects, especially stomach bleeding and kidney problems.

    Naproxen should not be used in CHILDREN younger than 12 years old without first checking with the child's doctor.

    Naproxen may cause harm to the fetus. Do not use it during the last 3 months of pregnancy. If you think you may be pregnant, contact your doctor. You will need to discuss the benefits and risks of using Naproxen while you are pregnant. Naproxen should not be used during labor. Naproxen is found in breast milk. Do not breast-feed while taking Naproxen.
