Ulcerative Colitis Treatment

About Asacol (mesalamine)

Asacol is Proven to Help Treat Flare-Ups

Asacol has been proven to help treat mild to moderate flare-ups of ulcerative colitis.

In six-week clinical studies of flare-ups, Asacol helped many patients reduce their symptoms of ulcerative colitis, including number of bowel movements and rectal bleeding, for some in as early as three weeks.*

Asacol is the #1 most prescribed oral 5-ASA medication27 – over 20 million prescriptions have been written since 1992.28 In 2007 Asacol celebrated its 15th year as a therapy for UC.

Asacol is Proven to Help Maintain Remission

In a six-month study, patients taking Asacol continuously at a maintenance dose were more likely to remain in remission, as compared to those taking a placebo (sugar pill).*

Ulcerative colitis rarely goes into permanent remission. The risk of flare-ups can be substantially reduced by the continued use of Asacol at the maintenance dose as directed by your doctor.
