I have pancolitis, but was prescribed Asacol only. Started out with 800 mg. three times a day, but only twice a day since no longer in a flare.
I honestly have more problems with internal hemis than the pancolitis as far as pain goes. I had a very "noisy" stomach (you could hear it across a room) and terrible diarhea, but never any pain when I was in a flare. I definitely consider myself lucky after reading this forum. I'm a big wuss when it comes to pain.
