Labetalol
Summary
Labetalol is used to treat high blood pressure, which is also known as hypertension. It also helps with angina, which is chest pain due to reduced blood flow to the heart, and certain irregular heartbeats. It can be used alone or with other medications to manage these conditions effectively.
Labetalol works by blocking certain receptors in the body called beta receptors, which are involved in regulating heart rate and blood pressure. By blocking these receptors, it helps lower blood pressure and reduces the workload on the heart, making it effective for managing high blood pressure and certain heart conditions.
The usual starting dose of Labetalol for adults is 100 mg taken twice daily. Your doctor may adjust your dose based on your response and needs. The maximum recommended dose is 2,400 mg per day. It is taken orally, with or without food, and should be swallowed whole without crushing or chewing.
Common side effects of Labetalol include dizziness, fatigue, and nausea. These occur in a small percentage of people taking the medication. If you experience these side effects, they may be temporary or unrelated to Labetalol. It's important to talk with your doctor before stopping any medication.
Labetalol can cause a drop in blood pressure, leading to dizziness or fainting, especially when standing up quickly. It's contraindicated in people with severe bradycardia, which is a very slow heart rate, or heart block, which is a problem with the heart's electrical system. Always consult your doctor before starting Labetalol.
