Banatrol Plus Does NOT Help with Diarrhea

The FDA-labeled Banatrol Plus product in the evidence is a topical pain relief lotion for muscle and joint aches—it is NOT indicated for diarrhea treatment and should not be used for this purpose 1.

Critical Clarification

There appears to be confusion between two completely different products:

  • Banatrol Plus (topical): An FDA-labeled external pain relief lotion containing ingredients for arthritis/muscle pain. The FDA label explicitly states "For external use only" and warns against ingestion 1.

  • Banana flakes (oral supplement): A different product containing dried banana powder that has been studied for diarrhea management.

If You're Actually Asking About Banana Flakes for Diarrhea

Banana flakes may be offered as a safe, cost-effective adjunctive treatment for diarrhea in enterally-fed patients, though they are not mentioned in current infectious diarrhea guidelines 2.

Evidence for Banana Flakes:

  • A 1997 randomized trial in critically ill tube-fed patients showed banana flakes reduced diarrhea severity comparably to medical treatment, with 57% of patients diarrhea-free versus 24% in the medical treatment group 2.

  • Banana flakes can be used concurrently during C. difficile workup without interfering with diagnosis 2.

Important Caveat:

  • Monitor INR closely in patients on warfarin: Banana flakes may resolve diarrhea, leading to increased vitamin K absorption and subtherapeutic INR, potentially reducing warfarin efficacy 3.

Guideline-Recommended Treatments for Infectious Diarrhea

The 2017 IDSA guidelines recommend 4:

  1. Probiotics: May reduce symptom severity and duration (weak recommendation, moderate evidence)
  2. Bismuth subsalicylate: Mildly effective for symptom relief
  3. Loperamide: Reduces stool volume and duration in healthy adults with non-bloody diarrhea (avoid in children <3 years, bloody diarrhea, or suspected STEC/Shigella)
  4. Oral rehydration: Cornerstone of management across all ages

Do not use the topical Banatrol Plus product for diarrhea—this is a dangerous misapplication of an external-use-only medication.
