The incidence of type 2 amiodarone-induced thyrotoxicosis (AIT) is increasing. A new study provides evidence that glucocorticoid therapy is safe, effective and associated with prompt restoration of euthyroidism in previously untreated type 2 AIT. The outcome of initial combined glucocorticoid and thionamide therapy can also help differentiate between type 1 and type 2 AIT.
