Which statement is true regarding antidiarrheal use in Clostridium difficile infection?

• A. Antidiarrheals are recommended
• B. No, antidiarrheals should not be used
• C. Antidiarrheals only if diarrhea resolves
• D. Antidiarrheals are the first-line therapy

Answer: (B)

In Clostridium difficile infection, antidiarrheals are avoided because slowing intestinal movement can trap toxin-contaminated stool in the colon and raise the risk of serious complications like toxic megacolon or ileus. The diarrhea in CDI is part of how the body tries to clear the toxin-producing bacteria; decreasing motility can prolong toxin contact with the colonic lining and hinder toxin elimination. For this reason, antidiarrheals are not used as part of standard CDI treatment, which focuses on specific antibiotic therapy (such as oral vancomycin or fidaxomicin) and supportive care. They should not be given even if diarrhea persists, and they are not first-line therapy. If there is concern for ileus or megacolon, antidiarrheals are avoided to prevent worsening those conditions.
