Which statement about the management of antibiotic-associated diarrhea due to C. difficile is true?

• A. Stop the offending antibiotic if possible and give metronidazole
• B. Continue the antibiotic and give metronidazole
• C. Stop all antibiotics and observe
• D. Switch to a different antibiotic for C. difficile

Answer: (A)

When C. difficile has taken over after antibiotic use, the priority is to remove the trigger and treat the infection. Stopping the offending antibiotic reduces ongoing disruption of the gut microbiome, which helps normal flora recover and slows the toxin-producing organism. At the same time, starting a drug active against C. difficile, such as metronidazole in milder cases, directly targets the infection and can resolve symptoms. Continuing the antibiotic would keep feeding the problem, stopping all antibiotics isn’t appropriate when there’s an active infection to treat, and switching to another antibiotic aimed at C. difficile isn’t the correct strategy because we need a specific anti-C. difficile therapy rather than another antibiotic that could perpetuate dysbiosis. In short, remove the trigger and initiate targeted therapy against C. difficile.
