Naproxen

Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) used to reduce pain, swelling, and fever. It works by blocking substances in the body called prostaglandins that help cause inflammation and pain.

It is commonly used for arthritis, menstrual cramps, muscle aches, and other painful conditions. Naproxen can raise the risk of stomach bleeding, heart problems, and kidney issues, so it should be used only as directed, especially in older adults or people with a history of ulcers or cardiovascular disease.
