How can you get rid of c.diff. (clostridium difficile)?

Therapy: For c. Difficile is usually, in today's bugs, oral vancomycin.

Antibiotics: Standard first line therapy is Metronidazole for 10-14 days. 1st recurrence can be the same course again or use oral vancomycin. Severe cases or frequent reoccurrences should utilize oral vancomycin sometimes with a prolonged taper over several weeks. Fidaxomicin is a newer therapy that has good efficacy and reduction in recurrence rates compared to vanco.

Agree with above: The infection has a propensity to relapse hence, fecal matter transplantation should be considered in some cases to restore gut microbiome. Would try not taking antibiotics if can be avoided.
