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."
