I was put on Apriso by the first doc who diagnosed the UC. It made the problem 1000 times worse than before he did the colonoscopy and the diagnosis. My only sympton prior to the colonoscopy was the bleeding. After apriso, I had constant, uncontrollable watery diar., cramps, etc. Even after I called repeatedly, he insisted I stay on Apriso. I did not. Got a new doc. She also wanted me to try Apriso, but after one week, she acknowledged it was not for me. I probably should have informed the FDA or Apriso makers, as a warning to others, but I didn't.
