Indomethacin is a nonsteroidal anti-inflammatory drug (NSAID) commonly used to reduce inflammation, pain, and fever. It is often prescribed for conditions such as arthritis, gout, bursitis, and tendonitis. Indomethacin works by inhibiting the production of certain natural substances in the body that cause inflammation. It is available in various forms, including oral capsules, extended-release capsules, suppositories, and as an injectable solution. As with all medications, it should be used under the guidance of a healthcare professional due to potential side effects and interactions with other medications.
