I was on
it for a while, but
it causes HORRIBLE gas, so was taken off. My doctor said
it could cause some hair loss, but not like Pentasa, that I have been on for years. I feel like a shedding dog. I guess you just learn to live with it. As long as I feel better, I will live with the hair loss, and after 5+ years, I haven't notices thinning...YET! Good luck.
