I had the SIBO breath test done in my GI doc's office, and I, too, have a confirmed diagnosis for SIBO. I am currently taking a 14 day course of the antibiotic Xifaxan, 550 mg, 3 times a day (it is very expensive--no generic). It specifically targets the small intestine where SIBO lies. I sure hope it works as I have been dealing with SIBO since January. My first GI doc did not do the test. He simply diagnosed it empirically based on my GI history and symptoms, and put me on antibiotics (mainly Cipro) which I had to stay on until June because every time I finished a 10 day course, my symptoms returned. Finally, I got better in June and he decided to put me on broad spectrum antibiotics for 5 days, then 25 days off; repeat with 5 days of a different antibiotic, then 25 days off, then a 3rd antibiotic, repeat the cycle for at least a year. My general practitioner and I decided this was only treating the symptoms & keeping them at bay, not addressing the problem, and my GP was also concerned, as was I, about the chance of Cdiff from long term use of so many antibiotics, so he referred me to a gastroenterologist he recommended. This is where I had the breath test done and was prescribed the Xifaxan.
