Oxaprozin (
Daypro®) is a prescription medicine used to treat pain, inflammation, swelling, and stiffness. It is part of a class of drugs called nonsteroidal anti-inflammatory drugs, or
NSAIDs for short.
Oxaprozin is manufactured by Pfizer, Inc.
Oxaprozin and other NSAIDs work by inhibiting the action of certain hormones that cause inflammation and pain in the body. These hormones are called prostaglandins.
By blocking the effects of prostaglandins, oxaprozin is useful at reducing pain, inflammation, and joint swelling associated with different forms of
arthritis and other painful conditions.
