What is the drug of choice for treating C. difficile infections?

The preferred treatment for Clostridium difficile infections is vancomycin, making it the drug of choice in most situations. This is especially true for severe cases or when the infection is recurrent. While metronidazole has been used as an alternative and can be effective for mild cases, current clinical guidelines recommend vancomycin due to its superior efficacy in more severe and recurrent infections. Clindamycin and doxycycline are not typically used for treating C. difficile infections, as they are not effective against this specific pathogen.
