An uncommon side effect: amiodarone-related hypothyroidism in a patient with negative thyroid autoantibodies.

Abstract

Amiodarone is an antiarrhythmic drug frequently used in cardiac dysrhythmias. One of the most important side effects of amiodarone is thyroid dysfunction. Amiodarone-induced thyrotoxicosis (AIT) and amiodarone-induced hypothyroidism (AIH) can occur depending on individuals' iodine status and previous thyroid disease. In this case, we aimed to present the hypothyroidism that developed in a patient with negative thyroid autoantibodies after amiodarone use.
