Caution: Grapefruit juice may impose risk on patients with long QT syndrome

Grapefruit juice is already listed as a substance to avoid when taking QT-prolonging medications because it increases the toxicity of many drugs. Investigators have now confirmed the QT-prolonging effects of grapefruit juice in a new study and call for a stronger warning to patients who are taking QT-prolonging drugs or who have long QT syndrome because of the potential risk. They report their findings in Heart Rhythm, the official journal of the Heart Rhythm Society and the Cardiac Electrophysiology Society.
