I am an American currently living in Mexico, started having bleeding when having a BM and stools looked like worms sometimes, so the doctor here, after first treating me with a probiotic and same problem is still with me, so he said maybe a parasite and gave me Bactim and 2 pills of Amoebriz. If still sick after treatment with this to see a specialists for further tests. Just need to know side effects of Amoebriz, never took it before. I am 65 yrs old and i do suffer from diverticulitis .
