Topic overview

Start with the big picture

Management with adjunctive drugs targets rapid symptom relief, hormone release, or peripheral conversion of T4 to T3. Beta-blockers are used for symptom control; non-dihydropyridine calcium channel blockers can provide rate control when beta-blockers are unsuitable. Iodide, iodinated contrast agents, glucocorticoids, cholestyramine, and lithium have distinct roles in suppressing hormone release or effects. These therapies are generally temporary and do not replace definitive treatment. Their selection and use depend on clinical context, contraindications, and monitoring needs. The deeper lesson organizes these agents by mechanism and indication and highlights key cautions, including timing of iodide relative to thionamides and the risk of rebound after abrupt withdrawal of iodide or lithium.
