Precautions

The US FDA requires a Risk Evaluation and Mitigation Strategy (REMS) for dronedarone. It includes a medication guide and communication plan. Additional information is available at www.fda.gov/Drugs/DrugSafety/PostmarketDrugSafetyInformationforPatientsandProviders/ucm111350.htm.

BOXED WARNINGS:
-HEART FAILURE: Dronedarone is contraindicated in patients with symptomatic heart failure with recent decompensation requiring hospitalization or NYHA Class IV heart failure. Dronedarone doubles the risk of death in these patients.
ATRIAL FIBRILLATION (AF): Dronedarone is contraindicated in patients in atrial fibrillation (AF) who cannot be cardioverted into normal sinus rhythm. Dronedarone doubles the risk of death, stroke, and hospitalization for heart failure in patients with permanent AF.

Safety and efficacy have not been established in patients younger than 18 years.

Consult WARNINGS section for additional precautions.
