What Is Indomethacin?
Simply put, Indomethacin belongs to a group of medicines called NSAIDs. NSAID stands for Nonsteroidal Anti-inflammatory Drug. This medicine works by blocking natural chemicals in your body that cause pain and swelling. Because of this, it helps ease the discomfort caused by joint pain, arthritis, and other swelling conditions.
Doctors often choose this medicine when milder pain relievers do not provide enough comfort. However, because it is strong, it requires careful use and close monitoring by your healthcare team. Always follow your prescription instructions carefully to get the best results.
