I was on Rifaximin for only a week b/c it made my symptoms so much worse; studies have shown that it only helps 50% of UC patients.
However, there are a couple people on this board who had success w/ Rifaximin.
Female, Age 19
9 Asacol, Rowasa, 1000 mg Canasa, Proctofoam, Rifaximin 2/day
Digestive Advantage (Crohn's & Colitis), 1 Florastor, 50 mg 6MP, 1 Primadophilus reuteri, Remicade (4 infusions), 2.4 g Lialda, 1 Forvia, 6 Colazal/day, 2 Anucort
