I was on it as a post infection treatment and I unfortunately learned the hard way about one of the common side effect. Over long term use, it can do irreversible damage to your GI system. As I often put it, it broke my pooper. Even now, many years after not having taken it anymore, and I still have issues with frequent diarrhea. Granted, my issues now are no longer to the extent that they were, and are also no longer at a point of sudden incontinence, but I pay the price to this very day for that decision. That said though, GI system aside, it kept me alive and otherwise healthy for many years, and considering some of the side effects of some of the alternative treatment options at the time, a broken pooper is but a small price to pay.
