In several clinical trials, 200 mg of oral fidaxomicin administered every 12 hours for 10 days has been noninferior to 125 mg of oral vancomycin administered every 6 hours for 10 days for the treatment of C difficile. [57] No difference in cure rates based on C difficile disease severity was reported. Symptomatic improvement is generally expected within 2-3 days.
