Gilead Sciences Inc. said nine patients taking its hepatitis C drugs Harvoni or Sovaldi along with the heart treatment amiodarone developed abnormally slow heartbeats and one died of cardiac arrest. Three required a pacemaker to be inserted.

Gilead said in an e-mailed drug warning to health-care providers on Friday that six cases of symptomatic bradycardia occurred within the first 24 hours of treatment and the remaining three within the first two to 12 days. The patients were all taking amiodarone, with three also using Harvoni, five receiving Sovaldi with Bristol-Myers Squibb Co.’s daclatasvir and one on Sovaldi with Johnson & Johnson’s Olysio. Gilead said the combinations aren’t recommended and it will update its product labeling.
