Asacol® (mesalamine) is a prescription drug used to treat ulcerative colitis. It comes in the form of delayed-release tablets and is approved for use in adults. Although Asacol is generally well tolerated, it is not without risks.
For example, this drug may cause kidney damage in some people. Your healthcare provider should check your kidney function (using a simple blood test) before you start Asacol and periodically thereafter. In some cases, the drug can actually worsen symptoms of ulcerative colitis. In addition, Asacol has been shown to pass through breast milk.
You should not take this drug if you have kidney disease, including kidney failure (renal failure). Asacol is also a poor choice for people who are allergic to mesalamine, any of the inactive ingredients in Asacol, or salicylate medications.
