How Taken
The recommended dose is 20 mg once daily or 10 mg twice daily. Feldene should be taken with food.
Drug Class and Mechanism
Feldene is a nonsteroidal anti-inflammatory drug (NSAID) that is effective in treating fever, pain, and inflammation in the body. As a group, NSAIDs are non-narcotic relievers of mild to moderate pain of many causes, including injury, menstrual cramps, arthritis, and other musculoskeletal conditions. NSAIDs, including feldene, block the enzyme in the body that makes prostaglandins (cyclooxygenase), resulting in lower levels of prostaglandins. Prostaglandins are responsible for causing many types of pain, fever and inflammation. As a consequence of taking NSAIDs, inflammation, pain and fever are reduced. The FDA approved Feldene in 1982.

Possible Side Effects
Most patients benefit from Feldene and other NSAIDs with few side effects. However, serious side effects can occur and generally tend to occur more frequently at higher doses. Therefore, it is advisable to use the lowest effective dose to minimize side effects. The most common side effects of Feldene involve the gastrointestinal system. It can cause ulcerations, abdominal pain, cramping, nausea, gastritis, and even serious gastrointestinal bleeding and liver toxicity. Sometimes, stomach ulceration and bleeding can occur without any abdominal pain. Black tarry stools, weakness, and dizziness upon standing may be the only signs of internal bleeding. Rash, kidney impairment, ringing in the ears, and lightheadedness also can occur.
