Thyroid Crisis Management

Labetalol is a medication that can be used during episodes of hyperthyroid crises to help reduce the activity of the sympathetic nervous system1. It works by blocking β1-β2 adrenergic receptors, which leads to a decrease in blood pressure and heart rate through negative inotropic and chronotropic effects. It also inhibits renin release2.
