Calming the Colon Where It Counts: Asacol HD (mesalamine delayed-release tablets) is a prescription medication indicated for the treatment of mildly to moderately active ulcerative colitis and for maintaining remission once symptoms improve. Each 800 mg tablet is designed with a special coating that carries the medication through the stomach and small intestine intact, releasing its active ingredient once it reaches the colon — right where ulcerative colitis inflammation occurs.

A Topical Approach to Inflammation: While the exact mechanism of mesalamine is not fully understood, it is believed to act topically on the lining of the colon rather than working systemically throughout the body. This localized approach is part of why mesalamine-based therapies are often a first-line option for mild to moderate ulcerative colitis, aiming to reduce inflammation directly at the source rather than broadly suppressing the immune system.

Straightforward Oral Dosing: For active disease, the typical adult dose is two 800 mg tablets three times a day for six weeks. Once remission is achieved, maintenance dosing typically drops to four 400 mg tablets daily, split into two to four doses. Tablets should always be swallowed whole — never cut, broken, or chewed — to preserve the delayed-release coating that targets the colon.

A Well-Studied Standard of Care: Mesalamine therapies like Asacol HD have been a mainstay of ulcerative colitis treatment for years, with a substantial body of clinical experience supporting their use in inducing and maintaining remission. Many patients and gastroenterologists rely on this class of medication as a foundation before considering more intensive therapies.

Working Toward Fewer Flares, More Good Days: Living with ulcerative colitis means managing an unpredictable disease, but consistent use of Asacol HD alongside your doctor's guidance can help extend the time between flares and support a better day-to-day quality of life.
