Functional Diarrhea: What to Do When Loperamide Has Not Improved Stool Frequency or Consistency
This protocol addresses patients with functional diarrhea (DD91.2) who continue to experience loose or watery stools despite initial treatment with loperamide — specifically when that therapy has failed to achieve meaningful improvement in stool frequency and consistency.
First-line management with loperamide did not reach its intended goals: improvement in stool frequency and stool consistency. This failure to respond adequately warrants escalation to the next treatment line.
The protocol for this situation involves a course of antibiotic therapy. The specific agent, dose, schedule, and duration are provided in the full structured regimen accessible below.
Treatment goal: Relief of loose or watery stools.
