Oxaprozin is used to treat the signs and symptoms of osteoarthritis and rheumatoid arthritis in adults and juveniles. It helps relieve joint pain, swelling, stiffness, and improves physical function.
As an NSAID, oxaprozin works by inhibiting cyclooxygenase (COX) enzymes, which reduces the production of prostaglandins. This results in decreased inflammation, pain, and fever.
Like all NSAIDs, oxaprozin carries risks of gastrointestinal bleeding, ulcers, and cardiovascular events. It should be used at the lowest effective dose for the shortest duration possible. Patients with kidney problems, liver disease, heart conditions, or a history of stomach bleeding should use with caution. It may interact with blood thinners, other NSAIDs, and certain blood pressure medications.
