In September I got both Ecoli & C-diff while traveling for the summer in our RV. Not fun! Dr. put me on Fidaxomicin, which is the drug name. Dificid is the brand name. My cost after insurance was $200, well worth it. It took awhile but eventually started feeling better after 2-3 months. Still had GI issues; diarrhea, abdominal discomfort but I kept taking a very good probiotic.
Unfortunately, I got really sick with my autoimmune issues in March which included a recurrence of C-diff. Again I was put on Fidaxomicin. The GI explained that cdiff is one of the bacteria that is always present in our GI but only causes problems when there is bad bacteria overgrowth. This is why the need for probiotics.
Fast forward to now; my GI issues are much better. I still take daily probiotics & have cleaned up my diet. I still have what GI doctor calls “ post infectious IBS” but so much better now. I can actually eat a salad now & then!
The probiotics suggested by the Dr. is Florastor.
Good luck on your GI journey!
