www.ncbi.nlm.nih.gov/pmc/articles/PMC3237300/Sounds fairly well worth trying for anyone, like myself, that is having trouble getting and maintaining solid remissions. I am puzzled that it isnt tried more by GI's, since it doesnt sound very risky, as it's not a systemic antibiotic and nor is it very broad spectrum. Of note, a cohort of UC patients that did not suffer any relapses in several months, in one study, used a combination of the drug plus s. boulardi, the probiotic yeast, but I suspect that all sorts if good probiotics could be pulsed with it, including for e.g. mutaflor, VSL3 etc.
