Two patients with amiodarone-induced thyrotoxicosis were treated successfully 
with potassium perchlorate and carbimazole while treatment with amiodarone was 
continued. These antithyroid drugs were stopped after the patients had became 
clinically and biochemically euthyroid. During follow up, when treatment with 
amiodarone continued, thyrotoxicosis did not recur. Amiodarone-induced 
thyrotoxicosis seems to be a transient condition that can be treated 
successfully with a short course of antithyroid drugs without stopping 
amiodarone treatment.
