Labetalol is a medication primarily used to treat high blood pressure, also known as hypertension. It belongs to a class of drugs called beta-blockers, which work by blocking certain receptors in the heart and blood vessels, leading to a decrease in heart rate and blood pressure. Labetalol can be administered orally or intravenously, making it versatile for different patient needs. This medication is often prescribed for pregnant women with high blood pressure, as it is considered safer than some alternatives. Common side effects may include dizziness, fatigue, and nausea. Regular monitoring of blood pressure is essential while using labetalol to ensure its effectiveness and safety.
