What Is Labetalol 300mg?
Labetalol is a prescription medication that blocks both alpha and beta receptors, which relaxes blood vessels and reduces the heart's workload. It is FDA-approved to treat high blood pressure (hypertension), either alone or with other blood pressure medications such as thiazide diuretics. Lowering blood pressure helps reduce the risk of strokes, heart attacks, and kidney problems over time. Labetalol 300mg tablets are the highest standard tablet strength and are typically used after dose titration under a provider's supervision.
What Does Labetalol 300mg Treat?
High blood pressure (hypertension)
Hypertension in combination with thiazide diuretics
