In this edition of Pharmacy Pearls, you will find information on drug-induced QTC prolongation, including which medications are commonly associated with prolonging the QTc interval, what kind of increase might be clinically relevant, and how often you would consider monitoring for QTc prolongation based on a patient’s individualized risk. There is also some guidance on how to manage medication interactions that might increase the risk as well as what to do if your patient should develop drug-induced QTc prolongation.
