Iâ€™ve gone back to work and havenâ€™t had a chance to look at this board for a while, but I thought Iâ€™d check in and see whatâ€™s up with the SIBO/Rifaximin efforts. I finished my 14 day rifaximin course two weeks ago now, and I still have IBS. It did not cure me. I pretty much lost faith in Pimentel and SIBO about half way through my treatment, when my symptoms did not seem to be abating. My symptoms mostly revolve around bloating, gas and pain, with occasional D. Antibiotics now seem to be too easy an answer. I figure that before pharmaceutical companies spend hundreds of millions of dollars trying to get something like cilansetron through the FDA, they do some in-house testing on the word-of-mouth cures to make sure their super-expensive drug sales donâ€™t get undercut by the sudden realization that $10 worth of antibiotics cures IBS. So, hereâ€™s my question: has anyone on this board been cured of IBS with rifaximin or any other A/B?
