"I was diagnosed with ulcerative colitis in 2008 treating it with Canasa and Protofoam. It reoccurred in 2010 which had to be treated aggressively with prednisone, Asacol HD, proctofoam and Canasa. I did not continue taking the Asacol HD because of the price. My ulcerative colitis reoccurred again in 2011. Currently, I am taking prednisone plus 3 Asacol HD a day and am very satisfied with the medicine. No side effects for me. Once the prednisone is finished it's Asacol HD forever to prevent flare-ups/maintenance. Great medicine."
