Clinical significance and safety
Imodium (Loperamide) and Seroquel (quetiapine): Quetiapine-related QT warnings apply with loperamide; their bowel-slowing effects also raise concern about constipation or ileus. 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.
