Bezlotoxumab Injection

pronounced as (bez" loe tox' ue mab)

Why is this medication prescribed?

Bezlotoxumab injection is used to decrease the risk of Clostridium difficile infection (C. difficile or CDI; a type of bacteria that can cause severe or life-threatening diarrhea) from coming back in people at high risk for C. difficile infection. It is used along with an antibiotic to treat C. difficile. Bezlotoxumab is in a class of medications called monoclonal antibodies. It works by binding to a C. difficile toxin to stop its effects on the body.

How should this medicine be used?

Bezlotoxumab comes as a solution (liquid) to be injected intravenously (into a vein) over 60 minutes. Bezlotoxumab is administered as a single dose by a doctor or nurse.

Bezlotoxumab injection does not take the place of antibiotic treatment for C. difficile infection; continue your antibiotic treatment as directed by your doctor.
