Ketoprofen is a nonsteroidal anti-inflammatory drug (NSAID) that is used to treat pain or inflammation caused by arthritis.

The ketoprofen regular capsule is also used to treat mild to moderate pain, or menstrual pain.

Only ketoprofen extended-release capsules are used for treating arthritis. This form of ketoprofen will not work fast enough to treat acute (immediate) pain.

Ketoprofen may also be used for purposes not listed in this medication guide.


Ketoprofen can increase your risk of fatal  heart attack  or stroke. Do not use ketoprofen just before or after heart bypass surgery (coronary artery bypass graft, or CABG). Ketoprofen may also cause stomach or intestinal bleeding, which can be fatal.
