Labetalol tablets are used to treat high blood pressure (hypertension) by relaxing blood vessels and slowing the heart rate. This medication works by blocking both alpha and beta receptors in the body, which helps reduce the force and rate of the heartbeat and allows blood to flow more easily. It’s often prescribed with other medications to help prevent complications like stroke, heart attack, or kidney problems caused by uncontrolled blood pressure.
- Labetalol tablets are combined alpha- and beta-adrenergic receptor blockers
- Should not be abruptly stopped as this may worsen heart conditions
- Common side effects include dizziness, fatigue, and nausea
- May be taken with or without food, but consistency is essential

Labetalol Tablets Side Effects
Labetalol tablets may cause side effects such as dizziness, fatigue, nausea, and headache, especially when starting treatment or increasing the dose. More serious side effects include slow heart rate (bradycardia), low blood pressure (hypotension), and liver function changes. Rarely, allergic reactions or heart failure symptoms may occur. Patients with asthma or other breathing problems should use labetalol cautiously, as it may worsen bronchospasm. Diabetic patients should be aware that labetalol can mask symptoms of low blood sugar. It’s important not to stop the medication suddenly, as this may lead to a rebound increase in blood pressure or heart complications.

Labetalol Tablets Medication Description
Labetalol is a unique antihypertensive agent that combines selective alpha-1 adrenergic blocking and non-selective beta-adrenergic blocking properties. This dual mechanism allows it to lower blood pressure effectively by decreasing peripheral vascular resistance (via alpha blockade) and reducing heart rate and cardiac output (via beta blockade). Unlike pure beta-blockers, labetalol does not significantly reduce renal blood flow, making it a potential option in patients with kidney concerns.
Clinically, labetalol is used to manage both chronic hypertension and hypertensive emergencies. The medication is typically started at a low dose and titrated based on blood pressure response. Because of its ability to block both alpha and beta receptors, labetalol provides a balanced approach to blood pressure control without generally causing reflex tachycardia, a common issue with pure vasodilators. It is well tolerated, but patients should be monitored for signs of bradycardia, hypotension, and liver function abnormalities during long-term use. -
