What is naproxen (Naprosyn, Anaprox, Anaprox DS)?

Naproxen is in a group of drugs called nonsteroidal anti-inflammatory drugs (NSAIDs). Naproxen works by reducing hormones that cause inflammation and pain in the body.

Naproxen is used to treat pain or inflammation caused by conditions such as arthritis, ankylosing spondylitis, tendinitis, bursitis, gout, or menstrual cramps.

Naproxen may also be used for other purposes not listed in this medication guide.

What are the possible side effects of naproxen?

Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

Stop taking naproxen and seek medical attention or call your doctor at once if you have any of these serious side effects:

• chest pain, weakness, shortness of breath, slurred speech, problems with vision or balance;
• black, bloody, or tarry stools;
• coughing up blood or vomit that looks like coffee grounds;
• swelling or rapid weight gain;
• urinating less than usual or not at all;
• nausea, stomach pain, low fever, loss of appetite, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes);
• fever, sore throat, and headache with a severe blistering, peeling, and red skin rash;
• bruising, severe tingling, numbness, pain, muscle weakness; or
• fever, headache, neck stiffness, chills, increased sensitivity to light, purple spots on the skin, and/or seizure (convulsions).

Less serious side effects may include:

• upset stomach, mild heartburn or stomach pain, diarrhea, constipation;
• bloating, gas;
• dizziness, headache, nervousness;
• skin itching or rash;
• blurred vision; or
• ringing in your ears.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

What is the most important information I should know about naproxen?

This medicine can increase your risk of life-threatening heart or circulation problems, including heart attack or stroke. This risk will increase the longer you use naproxen. Do not use this medicine just before or after having heart bypass surgery (also called coronary artery bypass graft, or CABG).

Seek emergency medical help if you have symptoms of heart or circulation problems, such as chest pain, weakness, shortness of breath, slurred speech, or problems with vision or balance.

This medicine can also increase your risk of serious effects on the stomach or intestines, including bleeding or perforation (forming of a hole). These conditions can be fatal and gastrointestinal effects can occur without warning at any time while you are taking naproxen. Older adults may have an even greater risk of these serious gastrointestinal side effects.

Call your doctor at once if you have symptoms of bleeding in your stomach or intestines. This includes black, bloody, or tarry stools, or coughing up blood or vomit that looks like coffee grounds.

Do not use any other over-the-counter cold, allergy, or pain medication without first asking your doctor or pharmacist. Many medicines available over the counter contain aspirin or other medicines similar to naproxen (such as ibuprofen or ketoprofen). If you take certain products together you may accidentally take too much of this type of medication. Read the label of any other medicine you are using to see if it contains aspirin, ibuprofen, or ketoprofen.

Do not drink alcohol while taking naproxen. Alcohol can increase the risk of stomach bleeding caused by naproxen.

Avoid prolonged exposure to sunlight. Naproxen can make your skin more sensitive to sunlight, and a sunburn may result.
