I think Lialda is more commonly prescribed with UC.
My GI wanted me to go on Remicade for a fistula/abscess combo, but the HMO wouldn't let her give it to me and so I am on Lialda.
I've been taking it since yesterday only and so far haven't suffered any side effects.
I think GIs are more likely to prescribe this if you have Crohn's related problems in the rectum because it takes the longest to dissolve???
What about you? Where is your Crohn's active and do you get headaches from the Lialda? I read that that is the most likely side effect.
