Treatment for non-severe Clostridium difficile infection?

Treatment for non-severe Clostridium difficile infection?

• A. Metronidazole only
• B. Vancomycin, fidaxomicin, or metronidazole
• C. Ciprofloxacin
• D. No treatment required

Answer: (B)

Treating non-severe Clostridioides difficile infection requires an antibiotic that acts in the colon to clear the organism. The best options are oral vancomycin or fidaxomicin, with metronidazole still acceptable if the first-line drugs aren’t available or affordable. Vancomycin stays in the gut and delivers high local concentrations, making it very effective for CDI. Fidaxomicin also works well and tends to have lower relapse rates. Metronidazole is included as an alternative mainly when the other two aren’t accessible, but it’s generally less preferred due to lower efficacy and more systemic side effects. Ciprofloxacin isn’t a treatment for CDI, and doing nothing would allow the infection to worsen.
