On March 24, the U.S. Food and Drug Administration (FDA) issued a warning against taking the antiarrhythmic drug amiodarone in combination with hepatitis C drug treatments and another direct acting antiviral. In their announcement, the FDA stated that amiodarone “taken together with either the hepatitis C drug Harvoni (ledipasvir/sofosbuvir) or with Sovaldi (sofosbuvir), taken in combination with another direct acting antiviral for the treatment of hepatitis C infection” can cause symptomatic bradycardia. The warning will be added to the labels of Harvoni and Sovaldi, and the FDA will continue to investigate the cause of the heart-related events.
