@dpete19743 I developed Cdiff after taking Clindamycin for a sinus infection. I went through 4 Cdiff episodes in 2018 before taking Dificid (fidaxamicin) which finally worked for me. Prior to that I took Vancomycin for the 2nd and 3rd bout. For the 3rd bout, I did the Vanco pulse and taper for 6 weeks. The only real side effects from the meds are now I have a ringing in my ears. (Tinnitus) And I also have terrible gas late and night and early in the morning when I first get up which I think is related to Cdiff. I also now take Florastor or a probiotic with S Boulardii which was recommended by my gastroenterologist.
