Treatment

After three relapses, patients may be treated with oral fidaxomicin, a narrow-spectrum antibiotic. The usual dosage is 200 mg twice a day orally for 10 days. Fidaxomicin is considered to be superior to vancomycin for severe CDI. The major downside of treatment with fidaxomicin is the cost of medication. A 10-day course may cost up to US$3500. When a patient is deteriorating or progressing to severe-complicated disease the addition of intravenous tigecycline merits considerations. Patients with high risk of relapse may also benefit from the addition of the monoclonal antibody bezlotoxumab to the standard of care.
