I took Azulfadine for 33 yrs. NO problems. 34th yr, my new GI Doc insisted I switch to Asacol.
So, for 2 yrs that's wht I took everyday for my mild UC instead of Azulfadine. Well, after 2 yrs, I went for my screening colonoscopy wen his office called me to schedule it. My colon was ttly clear of polyps and normalized mucosa 2 yrs before. After 2 yrs taking Asacol, I had suspicious lesions up and down my entire colon, high and low grade dysplasia visually, as well as my biospies taken during colonoscopy, + tons of polyps along my entire colon and rectum.
My Dr. told me when my results returned I had to have my colon and rectum removed within a month. So now I have no colon or rectum, but a jpouch.
I KNOW that switching to the Asacol, going off Azulfadine was the biggest mistake, sealed my fate developing colon cancer. Too coincidental not to be the reason. Well, I "fired" that GI Doc after that. Hired a much better GI Dr. while getting scheduled for my surgeries.
