Bezlotoxumab Injection

Brand Name(s): Zinplava®

WHY is this medicine 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 who are at high risk for C. difficile infection and who are already taking an antibiotic drug to treat Clostridium 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.
