There is little data to suggest that promethazine, prochlorperazine, and metoclopramide increase QTc as low dose monotherapy, however when given with other QTc prolonging meds, can contribute to QTc prolongation. For agents that have QTc prolonging effects, most of the risk is associated with higher doses
