Patient Education

Mesalamine Rectal


Rectal mesalamine is used to treat ulcerative colitis (a condition which causes swelling and sores in the lining of the colon [large intestine] and rectum), proctitis (swelling in the rectum), and proctosigmoiditis (swelling in the rectum and sigmoid colon [last section of the colon]). Rectal mesalamine is in a class of medications called anti-inflammatory agents. It works by stopping the body from producing a certain substance that may cause inflammation.
