A couple of years ago I ended up in ER and was admitted to hospital for a few days. While I was there they gave me iv pred, antibiotics and sent me home with my usual script for Asacol. A few weeks went by and I wasn't feeling much better. My GI called me in for an office visit and informed me that they weren't doing enough for me and he wanted me to start taking Imuran. He wrote out the script. I went to fill it, balked at the price and went home without it. When I got home I looked it up on the computer. The side effects not only scared me skinny....but within two days I was feeling just fine. Stayed on the Asacol, watched what I ate and didn't need the Imuran.
I think I was scared into spontaneous remission. Seriously. I was feeling so lousy until the Imuran event. So, I guess it can happen.
