What is this medication for?
Naproxen sodium belongs to the class of medications called nonsteroidal anti-inflammatory drugs (NSAIDs). It works by reducing a natural chemical produced in response to injury, thus relieving inflammation, swelling, and pain. Naproxen is used to relieve the symptoms of osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, and juvenile arthritis. This medication may also be used to treat symptoms of tendonitis, bursitis, acute gout, pain, and menstrual cramps.
