Question: what antibiotic is used to treat c diff?
Answer: These antibiotics keep C. difficile from growing, which in turn treats diarrhea and other complications. Your doctor may prescribe vancomycin (Vancocin HCL, Firvanq) or fidaxomicin (Dificid). Metronidazole (Flagyl) may be rarely used if vancomycin or fidaxomicin aren't available.
