Popular FAQ

Research studies looking at patients who received daily oral doses of 4 to 6 grams of mesalamine showed that 80% of patients achieved complete or significant clinical improvement within 4 weeks.

Some forms of mesalamine are used long-term as a maintenance therapy in ulcerative colitis to help prevent symptoms from flaring up. Not all forms or brands of mesalamine are used long-term, so check with your doctor about your specific medicine. Call your doctor if your ulcerative colitis symptoms get worse after starting treatment.

The best time to take or use mesalamine will depend on the specific product you are using and why you are using it (ulcerative colitis induction or maintenance, ulcerative proctitis). Some products may need to be taken with food while others are taken on an empty stomach. Check with your doctor.

Mesalamine is an antiinflammatory, not an immunosuppressant. It may be one of the first treatments used for ulcerative colitis (UC) to lessen symptoms like diarrhea, rectal bleeding, or stomach pain. Immunosuppression is not a listed side effect for mesalamine. Other medicines used for UC, like prednisone, can suppress the immune system.

Brand name products of mesalamine may be more expensive than generic options. Some, but not all mesalamine products are available as generics. Your insurance should help pay for generics, or if you are paying out-of-pocket, ask your healthcare provider if there is a more affordable option.

Mesalamine is available as delayed-release tablets or capsules, extended-release capsules, and rectal preparations like suppositories or enemas. The maximum dose will depend upon the specific product you are using and your diagnosis. Only use the dose prescribed by your doctor.

Mesalamine is used in some patients with ulcerative colitis as a maintenance (long-term) treatment to help you stay in remission (without active symptoms). Other treatments for ulcerative colitis or proctitis are only taken short-term. Ask your doctor when you can stop taking treatment.

Common side effects of mesalamine include stomach problems (such as burping, abdominal pain, constipation, and diarrhea); a headache or dizziness; nasal problems, such as nasal congestion, runny nose, sneezing, or itching; or a rash. For most people, these side effects lessen or go away after a few weeks of treatment. More serious side effects with mesalamine are less common or rare, but include allergic reactions, bloody diarrhea or blood in the urine, and an intolerance syndrome. Continue reading
