Patient Education

Diclofenac and Misoprostol


The combination of diclofenac and misoprostol is used to relieve the pain, tenderness, swelling, and stiffness caused by osteoarthritis (arthritis caused by a breakdown of the lining of the joints) and rheumatoid arthritis (arthritis caused by swelling of the lining of the joints) in patients who have a high risk of developing stomach ulcers. Diclofenac is in a class of medications called NSAIDs. It works by stopping the body's production of a substance that causes pain and inflammation. Misoprostol is in a class of medications called prostaglandins. It prevents ulcers caused by diclofenac by protecting the stomach lining and decreasing stomach acid production.
