I'm on Lialda, and it doesn't do too much for me. I do notice an increase in symptoms if I don't take it. But when I do take it, it just sort of maintains whatever state I happen to be in at the time. Last summer, I had lost 30 lbs due to my flare-up, and after Lialda and Prednisone not having any major impact, my dr started me on Remicade. It worked well for a while - never got fully into remission, but I got to a point where things were tolerable and manageable with no blood. Now I'm in another flare up though and after regaining the 30 lbs last year, I have now lost 20 lbs. I'm not sure what the next step is for me medication-wise. I'll be going in for another colonoscopy this week.
Best of luck to your son.
