I have reacted horribly sdo far to every 5ASA but have yet to try Lialda. In each case (coated sulfasalazine, asacol, dipentum and colazol) I got severe to extreme abdominal pains, D and bleeding, so I am afraid to try Lialda, especially since you take fewer per day i..e each one has more active drug in it, and being coated you can't chop it into a smaller size to try it. However, it sounds like your adverse reaction to 5ASA's has not been quite as obvious (?) as my case and in any case you have started the Lialda so you will know within a few days. (My adverse reactions were severe enough that I had to end within 24 h).
