Treatment of Hyperthyroidism in Amiodarone-Induced Thyrotoxicosis Type 2 (Thyroid Tissue Destruction)
This protocol covers hyperthyroidism arising specifically from amiodarone-induced thyrotoxicosis type 2, where thyroid tissue destruction — rather than excess hormone synthesis — is the underlying mechanism.
Amiodarone-induced thyrotoxicosis can be type 1 (hormone overproduction) or type 2 (destructive thyroiditis). Distinguishing between the two is essential because the treatment approach differs entirely. This protocol is specific to type 2.
The cornerstone of management in type 2 involves a specific class of anti-inflammatory agent. A separate and important consideration governs whether amiodarone itself should be continued or stopped — discontinuation requires careful evaluation of cardiac safety and is not routine. The complete sequencing, monitoring, and decision framework are in the full protocol.

- Amiodarone should not be discontinued unless it can be stopped safely, without triggering cardiac complications.
