Pimozide and Sotalol: interaction and safety
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
Pimozide combined with an established systemic QT-prolonging medicine presents a serious arrhythmia risk.
Clinical significance and safety
Pimozide and Sotalol: Pimozide combined with an established systemic QT-prolonging medicine presents a serious arrhythmia risk. This combination is contraindicated under the cited pimozide product information for established QT-prolonging partners. It needs prompt prescriber or pharmacist review, not self-directed dose changes. 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.
