Correct answer: AStart levothyroxine while continuing amiodarone if cardiology agrees

Amiodarone-induced hypothyroidism is usually treated with levothyroxine, and amiodarone can often continue when clinically essential. Carbimazole and radioiodine treat hyperthyroidism. Cardiology involvement matters because arrhythmia control may be life-saving.
