Naprosyn (naproxen) is a nonsteroidal anti-inflammatory drug (NSAID). Naproxen works by reducing hormones that cause inflammation and pain in the body.
Naprosyn is used to treat pain or inflammation caused by conditions such as rheumatoid arthritis, osteoarthritis, ankylosing spondylitis, tendinitis, bursitis, gout, or menstrual cramps.
Naprosyn may also be used for purposes not listed in this medication guide.
You should not use Naprosyn if you have a history of allergic reaction to aspirin or other NSAID (nonsteroidal anti-inflammatory drug).
Naprosyn can increase your risk of fatal heart attack or stroke, especially if you use it long term or take high doses, or if you have heart disease. Do not use this medicine just before or after heart bypass surgery (coronary artery bypass graft, or CABG).
