How long were you on the 6MP? I was on it for 3 weeks, feeling OK, and then started having severe upper abdominal pain. After 3 days of only getting worse and reading on the net the side effects of 6MP, I went to the emergency room, and sure enough, I had pancrea*** brought on by the 6MP. I stayed in the hospital on IV for liquids and no food or water for 2 days. I pushed to come home on Christmas Day, but just started on popcicles and apple juice on the 26th. Today I had some yogurt. I was taking pentasa for an obstruction in September, but developed a bad rash and had to stop taking it. Now I'm only on Entocort 3 mg/3 x/day. You should probably wait until your current rash completely clears before starting the Pentasa so you will know for sure if the rash returns that it is the Pentasa. I'm beginning to think about
taking myself off all drugs and going the homeopathic route.
