Hi, all. So I've been on Imuran for years for Crohn's, colon only. I was in remission, but now a series of fecal calprotectins says I have ongoing mild inflammation. Once in a while I see a bit of blood and have lots of gas, once in a while some urgency. Otherwise no diarrhea, cramping, bleeding, none of that. (I wonder if my symptoms are diet related. ) Because of the calprotectin results while on Imuran, now my doc says maybe I should consider a biologic. I asked for the one with the least awful dangers, and he says Entyvio. What if I don't do this? I am 65 and on Medicare.... and dreading another drug. Thank you!
