I take Apriso for Crohn's. It's very similar to Asacol, except you only take 4 pills once a day. With Asacol, it was 4 pills THREE times a day. Oh, and Apriso doesn't stain the toilet like Asacol does. I take it as a maintenance drug, although I really couldn't tell you how much it helps me anymore since I started the Cimzia.
