Labetalol is a medication used to treat high blood pressure and in long term management of angina. This includes essential hypertension, hypertensive emergencies, and hypertension of pregnancy. In essential hypertension it is generally less preferred than a number of other blood pressure medications. It can be given by mouth or by injection into a vein.

Common side effects include low blood pressure with standing, dizziness, feeling tired, and nausea. Serious side effects may include low blood pressure, liver problems, heart failure, and bronchospasm. Use appears safe in the latter part of pregnancy and it is not expected to cause problems during breastfeeding. It works by blocking the activation of β- and α-adrenergic receptors.
