Atenolol — Uses, Dosage, Side Effects & Safety

Drug class: Beta-1 selective beta-blocker

Overview

Atenolol is a prescription medication used to treat high blood pressure (hypertension), chest pain (angina), and to help prevent heart attacks. It belongs to a group of medicines called beta-blockers, which work by slowing down your heart rate and reducing the workload on your heart. By blocking certain natural chemicals in your body, such as adrenaline, atenolol helps your heart beat more regularly and with less force. This can lower blood pressure, reduce chest pain, and decrease the risk of future heart problems. Atenolol is often used as part of a long-term treatment plan for heart health. Key points: Always take atenolol exactly as prescribed, do not stop suddenly without consulting your doctor, and let your healthcare provider know about all other medications you are taking.
