Nadolol (nadolol) — Uses, Dosage, Side Effects & Safety

Drug class: Non-selective beta-adrenergic blocker (beta blocker)

Overview

Nadolol is a prescription medication used to treat high blood pressure (hypertension) and certain types of chest pain (angina). By lowering blood pressure, nadolol helps reduce the risk of strokes, heart attacks, and kidney problems. It is also sometimes used to manage irregular heart rhythms and to prevent migraine headaches. Nadolol works by blocking certain natural chemicals in your body, such as adrenaline, on the heart and blood vessels. This effect helps to lower heart rate, blood pressure, and strain on the heart. It is important to take nadolol exactly as prescribed and not to stop suddenly, as this can worsen heart conditions. Patients should be aware that nadolol may take several weeks to show its full effect. Regular monitoring of blood pressure and heart rate is recommended while on this medication.
