For Irritable Bowel Syndrome The only thing that gave me relief was this medicine. After having endoamoeba hystolitica (sp?), 3 years ago, and long after killing the amoeba, I had different symptoms related to intestines. Chronic loose bowels and bloating. I read about this medicine and convinced Doctor to get me a prescription for this (it wasn't as yet FDA approved for irritable bowel syndrome). Within 3 days I began to normalize, after 1 week was symptom free for 6 months. Slowly I am beginning to have problems again. I started my first dose again today and hope to normalize again. Wish it didn't seem to return.

For Irritable Bowel Syndrome This my third time taking xifaxan. First two times was 2 200mg 3xday. 6 tablets per day for 10 days for SIBO. Just started 550 MGS 3XDAY for 14 days. The cost is prohibitive $331 Co pay. So far not feeling much relief from abdominal pain. I was not retested for SIBO but prescribed this for IBS. I am also on gluten free and FODMAP diet. I have low IgA and IgG immunoglobulins. Everything seems to be just trial and error. I will continue to take it. Not very hopeful. Everything gets blamed on low immunoglobulins.
