Bezlotoxumab Injection


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.
