@femalegolfer I would ask to see a GI right now. The vancomycin didn't work for me either. I did the 10 days first and then I also did the vanco pulse & tapper for 6 weeks. I was good for 3 weeks after that. But then I had my 4th relapse and that's when I asked for Dificid (fidaxamicin). I had a friend who had taken the Dificid after her second Cdiff and it worked for her also. It's pricey and I'm sure that's why they wait and try other meds first. You also should be taking S. Boulardii. It's a probiotic that goes straight to the colon and it's not dissolved by the acid in your stomach. If you just tested positive again, what's the plan your doctor wants you on?
