Labetalol is primarily used as an antihypertensive medication, functioning through both alpha and beta-adrenergic blocking properties. It is effective in treating conditions such as hypertensive crises due to its ability to rapidly reduce blood pressure. Additionally, it can be used in the management of certain cases of supraventricular tachycardia (SVT) as a second-line agent because of its beta-blocking capabilities.

When examining the conditions listed, hypotension is not something Labetalol is designed to treat. In fact, it is contraindicated in patients with hypotension since the medication’s primary action is to lower blood pressure. Therefore, using Labetalol in a situation where blood pressure is already low would not be appropriate, marking hypotension clearly as a condition that Labetalol does not treat.
