Summary
Fidaxomicin is used to treat Clostridioides difficile-associated diarrhea, which is a type of diarrhea caused by a specific bacteria in the gut. It is not used for infections in other parts of the body because it mainly targets bacteria in the intestines.

Fidaxomicin should not be used if you are allergic to it or its ingredients. It is not suitable for systemic infections, which are infections affecting the whole body. Always consult your doctor about any concerns before starting Fidaxomicin.
