I have been on Asacol for 11 years. Right now I am in a flare - some days better than others. Earlier this summer, I was put on Lialda in place of Asacol for 6 weeks. I found my symptoms got worse. The active ingredients are the same in both medicines. I was bummed that the medicine didn't work for me but someone else on this forum said that their GI said Lialda isn't as effective for those with proctitis - not enough of the meds reach the end of the colon. My UC involves 35 cm. HOpe this helps.
