Amiodarone, prescribed for cardiac conditions, including dysrhythmia, is associated with bradycardia. However, few reports have demonstrated that bradycardia is observed when amiodarone is used in combination with sofosbuvir, a direct-acting antiviral drug for chronic hepatitis C. We herein report the case of a male patient in his 70s with chronic atrial fibrillation and prostatic hyperplasia and was also taking amiodarone, who experienced severe bradycardia and syncope a day after taking sofosbuvir and ribavirin for chronic hepatitis C. After discontinuing amiodarone, ribavirin, and sofosbuvir, bradycardia did not recur. Therefore, we must consider drug interactions between amiodarone and sofosbuvir in patients with severe bradycardia.
