Naprosyn 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). The risk may be greater if you already have heart problems or if you take Naprosyn for a long time. Do not use Naprosyn right before or after bypass heart surgery. Naprosyn may cause an increased risk of serious and sometimes fatal stomach ulcers and bleeding. Elderly patients may be at greater risk. This may occur without warning signs.
Naprosyn is used for:
Treating rheumatoid arthritis, osteoarthritis, ankylosing spondylitis, and juvenile arthritis. It is used to treat tendonitis, bursitis, gout, menstrual cramps, or mild to moderate pain. It may also be used for other conditions as determined by your doctor. Naprosyn is an NSAID. Exactly how it works is not known. It may block certain substances in the body that are linked to inflammation. NSAIDs treat the symptoms of pain and inflammation. They do not treat the disease that causes those symptoms.
Do NOT use Naprosyn if:
• you are allergic to any ingredient in Naprosyn
• you have had a severe allergic reaction (eg, severe rash, hives, trouble breathing, growths in the nose, dizziness) to aspirin or a nonsteroidal anti-inflammatory drug (NSAID) (eg, ibuprofen, celecoxib)
• you have recently had or will be having bypass heart surgery
• you are in the last 3 months of pregnancy
Contact your doctor or health care provider right away if any of these apply to you.
