Labetalol is a medicine used to manage high blood pressure. Relaxing blood vessels allows blood to flow more easily, putting less strain on the heart and circulatory system.
Labetalol belongs to a class of drugs called beta-blockers that also block certain "alpha" signals, which together help relax your blood vessels and ease the heart's workload. Its main purpose is to lower high blood pressure and reduce the strain on your heart. You'll find labetalol as the active ingredient in products such as Trandate.
Labetalol is often used for general hypertension, especially when quick control is needed. The medicine can also be part of treatment plans for high blood pressure that develops during pregnancy, a condition known as pre-eclampsia. Doctors sometimes prescribe it after heart surgery or for certain heart rhythm problems where the heart beats too fast. In some cases, it may be added when other blood-pressure medicines aren't enough on their own.
Labetalol blocks two types of signals that normally tighten blood vessels and speed up the heart. The vessels relax and the heart doesn't have to pump as forcefully, lowering blood pressure.
If you are pregnant, nursing, have a history of asthma, a slow heart rate, severe liver disease, or certain types of heart block, you should discuss these conditions with your prescribing health professional. Alcohol can increase low-blood-pressure effects, and other medicines that also lower blood pressure or affect heart rhythm may interact with labetalol. Certain herbal supplements, such as those containing high amounts of potassium, might also change how the drug works. Always read the medication's label for a complete list of possible interactions.
Older adults and people with existing heart or liver problems tend to report side effects more often. Those taking multiple blood-pressure medicines or using alcohol heavily may also experience stronger reactions.
Store labetalol tablets at room temperature, away from direct sunlight, moisture, and heat sources, and keep the bottle tightly closed when not in use. Most labetalol products are meant for long-term treatment, but the exact length of therapy depends on your individual health plan. For Labetalol-specific instructions, refer to the medication information supplied with the product.
