I hope you can find some type of treatment that will work for you. It sounds like you may have had an allergic reaction to the mesalamine in Pentasa, and sulfasalazine breaks down into mesalamine and a sulfa component too. Biologics may be your next step.
This is an old post, so your comment may be overlooked by most. It would be better if you create a new post to tell us about your experience with your illness and treatment, if you like.
