Excerpt

Loperamide is an FDA-approved synthetic phenylpiperidine opioid with high lipophilicity and is a medication used to treat various forms of diarrhea. Recognized and approved by the FDA, loperamide is an effective intervention for conditions such as traveler's diarrhea, irritable bowel syndrome associated with chronic diarrhea, and acute nonspecific diarrhea in patients older than 2. Loperamide is also indicated for conditions requiring reducing ileostomy output to manage diverse gastrointestinal challenges. However, this medication requires careful consideration due to its potential for misuse, with reports indicating a concerning increase in morbidity and mortality associated with high doses. This activity explores loperamide's indications, contraindications, activities, and adverse events, focusing on the essential elements crucial for members of an interprofessional healthcare team involved in managing patients facing toxicity and its related conditions.
