Amiodarone‐induced Thyrotoxicosis: Not a Benign Condition

Abstract

SUMMARYAmiodarone is a heavily iodinated drug effective in the control of various tachyarrhythmias. Despite its undoubted benefit, treatment with amiodarone is not without risk, because a number of potentially serious side‐effects may develop during therapy. Thyrotoxicosis is most commonly recognised but its potential consequences tend to be underestimated, and its treatment can be challenging and difficult. We report several cases of amiodarone‐induced thyrotoxicosis which serve to highlight the potential severity of the condition.
