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.
I believe it's possible. I have been on Lialda for almost a year and recently noticed hair loss. Since I am also bruising very easily, it could be more related to an underlying anemia, not necessarily the Lialda itself.
