Non-severe Clostridium difficile infection treatments include which options?

• A. Penicillin
• B. Ciprofloxacin
• C. Vancomycin, fidaxomicin, or metronidazole
• D. Amoxicillin

Answer: (C)

Non-severe C. difficile infection is treated with antibiotics that act in the colon where the bacterium sits, delivered orally to maximize local exposure and minimize systemic effects. The best-supported options are oral vancomycin or fidaxomicin, which provide strong cure rates and lower the chance of recurrence. Metronidazole remains a reasonable alternative when vancomycin or fidaxomicin aren’t available or if there are specific patient factors, though it is generally considered less ideal than the other two. Penicillin, amoxicillin, and ciprofloxacin are not appropriate treatments for C. difficile and can worsen the problem by further disrupting the gut flora without effectively targeting the toxin-producing organism.
