Patient Education

Fidaxomicin


Fidaxomicin is used to treat diarrhea caused by Clostridium difficile (C. difficile; a type of bacteria that may cause severe or life-threatening diarrhea) in adults and children 6 months of age and older. Fidaxomicin is in a class of medications called macrolide antibiotics. It works by killing bacteria in the intestines. Fidaxomicin will not treat infections in any other part of the body. Antibiotics such as fidaxomicin will not work for colds, flu, or other viral infections. Taking antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.
