So I've been taking daily flagyl for about a month now for what I'm pretty sure is chronic pouchitis. I had Cdiff a few months ago and though I retested negative for it after a round of Vanco, things have just not been the same. My GI wants to test for it again, so he had me stop the flagyl for a few days so I could do that. He also prescribed some vanco hoping it would help either way. I've got a couple more days to go till I can take the test flagyl free but things are getting rough! I haven't started the vanco yet because I assume that it would also interfere with accurate test results, but thought I would double check. I know it would provide some relief, but don't want to risk an inaccurate stool test. Anyone know if that is the case?
