Labetalol is a medication used to manage high blood pressure (hypertension). It belongs to a class of drugs known as beta-blockers, which work by blocking the action of certain natural substances in your body, such as adrenaline, on the heart and blood vessels. By doing so, Labetalol reduces heart rate, blood pressure, and strain on the heart. While it can be a lifesaver for many individuals dealing with hypertension, like any medication, it comes with potential side effects. This article aims to provide a comprehensive overview of these side effects, from the most common to the rare but serious ones, so you can make an informed decision about your health.
