Daypro is used to treat symptoms of osteoarthritis, rheumatoid arthritis, and juvenile rheumatoid arthritis, including pain, swelling, and stiffness.
As an NSAID, Daypro works by inhibiting cyclooxygenase (COX) enzymes, which reduces the production of prostaglandins—chemicals in the body that cause inflammation, pain, and fever.
Like all NSAIDs, Daypro may increase the risk of heart attack, stroke, and serious stomach problems including bleeding. It should be used at the lowest effective dose for the shortest duration possible. Patients with a history of asthma, stomach ulcers, or kidney problems should use caution and discuss their medical history with their healthcare provider.
