Mesalamine is used to treat ulcerative colitis (a condition which causes swelling and sores in the lining of the colon [large intestine] and rectum) and also to maintain improvement of ulcerative colitis symptoms. 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.
Mesalamine comes as a delayed-release (releases the medication in the intestine where its effects are needed) tablet, a delayed-release (releases the medication in the intestine where its effects are needed) capsule, a controlled-release (releases the medication throughout the digestive system) capsule, and as an extended-release (long-acting) capsule to take by mouth. Your doctor will tell you how often to take your medication, depending on your condition and how well your symptoms are controlled. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take mesalamine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Swallow the delayed-release tablets and delayed-release capsules whole; do not split, chew, or crush them. Be careful not to break the protective coating on the delayed-release tablets.
Continue to take mesalamine until you finish your prescription, even if you feel better at the beginning of your treatment. Do not stop taking mesalamine without talking to your doctor.
This medication may be prescribed for other uses. Ask your doctor or pharmacist for more information.
