In 2013, Asacol 400 mg tablets were removed from the market and replaced with Delzicol 400 mg capsules. Please see Delzicol for up-to-date information.
There is only one approved use (also called "indication") for Asacol® (mesalamine): the treatment of ulcerative colitis in adults.
Asacol belongs to a group of medications called aminosalicylates. It is thought that the medication works by inhibiting the production of inflammatory chemicals in the lining of the colon. Asacol decreases the production of prostaglandins and leukotrienes, chemicals that lead to the inflammation of ulcerative colitis.
For many medications, there are possible off-label (or unapproved) uses for the drug. However, there are no off-label indications for Asacol at this time.
