DRUG CLASS AND MECHANISM: Diclofenac belongs to a class of drugs called nonsteroidal anti-inflammatory drugs (NSAIDs) that are used for the treatment of mild to moderate pain, fever, and inflammation. Other members of this class include ibuprofen (Motrin), indomethacin (Indocin), nabumetone (Relafen), naproxen (Aleve) and several others. NSAIDs work by reducing the production of prostaglandins, chemicals that cause pain, fever and inflammation. NSAIDs block the enzyme that makes prostaglandins (cyclooxygenase), resulting in lower production of prostaglandins. As a consequence, inflammation, pain and fever are reduced. Since the response to different NSAIDs varies from patient to patient, it is not unusual for a doctor to try different NSAIDs for any given condition. The FDA approved diclofenac in July 1998.
PRESCRIBED FOR: Diclofenac is used primarily for the treatment of inflammation and pain caused by conditions such as rheumatoid arthritis, osteoarthritis, and ankylosing spondylitis. It also is effective in treating soft tissue inflammation that causes tendinitis and bursitis, and for treating dysmenorrhea (menstrual cramps).
