Apriso Side Effects and Interactions

Apriso is a form of mesalamine that is used to treat inflammation in the colon caused by ulcerative colitis. Apriso contains a patented delivery system for the mesalamine called Intellicor. Intellicor is an extended-release system that allows the mesalamine to travel through the digestive tract and be deployed in the colon, where it is needed. Other brand names of oral mesalamine include Pentasa, Asacol, Colazal, and Lialda.

How Is Apriso Taken?

If you miss a dose, take it as soon as you remember. If your next dose should be taken soon, just take that dose — don't double up, or take more than one dose at a time.
