Oxaprozin is a non-steroid anti-inflammatory drug, or NSAID. This medication is often prescribed to help reduce swelling, pain, tenderness and stiffness in patients who have osteoarthritis or rheumatoid arthritis. This medication works by stopping the body from producing an enzyme that contributes to fever and inflammation.
This medication can cause heart attacks or strokes. Patients who have a history of heart disease or whose families suffer from heart disease are at greater risk than those who do not have a history of heart problems. Patients should not take this medication shortly before or shortly after coronary bypass surgery because of this risk.
Oxaprozin can also cause serious stomach problems such as ulcers and gastrointestinal perforation. Call your doctor immediately if you have severe stomach pain, especially if it is combined with blood in your stool.
