Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) used to relieve symptoms of arthritis (osteoarthritis, rheumatoid arthritis, or juvenile arthritis) such as inflammation, swelling, stiffness, and joint pain.
Naproxen, like other NSAIDs, works to decrease swelling and to inhibit pain sensations. Naproxen reduces hormones that cause inflammation and chronic pain. The exact way it works is not completely understood. However, researchers believe it plays a role in inhibiting a substance called prostaglandin, which is associated with pain.
