Nabumetone belongs to a class of medications known as non-steroidal anti-inflammatory drugs (NSAIDs). Physicians commonly prescribe the medication to treat pain due to osteoarthritis or rheumatoid arthritis. The medication is used to reduce pain, stiffness, and swelling.

Nabumetone has anti-inflammatory, pain-reducing and/or fever-reducing properties. While its exact action is unknown, the anti-inflammatory effects may come from reducing the synthesis of compounds known as prostaglandins, which can cause pain and cramping in the body.

Taking nabumetone before coronary artery bypass graft (CABG) surgery can increase death risk from bleeding. The medication can cause ulcers, bleeding, and/or holes in the stomach or intestine. Elderly patients are especially at risk for gastrointestinal bleeding (FDA, 2005).
