This source-based reference is not a personal treatment recommendation. The relevance and management of an interaction depend on the exact products, route, dose and clinical situation.
Interaction mechanism
QT effects of loperamide and a fluoroquinolone may add, particularly when electrolyte loss is present.
Clinical significance and safety
Cipro (Ciprofloxacin) 500 mg and Imodium (Loperamide): QT effects of loperamide and a fluoroquinolone may add, particularly when electrolyte loss is present. The loperamide prescribing information advises avoiding combinations with other established QT-prolonging medicines. Excessive doses and electrolyte losses during diarrhoea make the risk especially important. Heart disease, a slow pulse and low potassium or magnesium can increase concern. A clinician determines whether ECG or electrolyte checks are needed. Fainting or new irregular palpitations require urgent assessment.
