Mesalamine / Mesalazine (Mesalamine (also known as Mesalazine)) — Uses, Dosage, Side Effects & Safety
Drug class: Aminosalicylate anti-inflammatory
Overview
Mesalamine (also called mesalazine) is a medication used to treat inflammatory bowel diseases, such as ulcerative colitis and, in some cases, Crohn's disease. It helps reduce inflammation in the lining of the colon and rectum, which can relieve symptoms like diarrhea, rectal bleeding, and abdominal pain. Mesalamine works by blocking the production of certain natural substances (prostaglandins and leukotrienes) in the colon that cause inflammation and tissue damage. It is available in several forms, including oral tablets, capsules, and rectal preparations (suppositories and enemas), allowing treatment to be tailored to the affected area. Key points for patients: Take mesalamine exactly as prescribed, do not stop suddenly without consulting your doctor, and report any unusual symptoms such as severe abdominal pain, chest pain, or signs of an allergic reaction. Regular monitoring may be needed to check for side effects.
