Used primarily as a nonsteroidal anti-inflammatory drug (NSAID) to relieve mild to moderate pain, mefenamic acid is commonly prescribed for conditions such as menstrual pain (primary dysmenorrhea), headaches, dental pain, and postoperative pain. It works by reducing hormones that cause inflammation and pain in the body. Due to its anti-inflammatory and analgesic properties, it is also used in the management of rheumatoid arthritis and osteoarthritis. Mefenamic acid is typically taken orally in tablet form and is intended for short-term use due to the increased risk of gastrointestinal and cardiovascular side effects with prolonged use.
