Propranolol

Common use

Propranolol is a beta-blocker used to treat high blood pressure, angina, heart rhythm disorders, and to prevent migraine headaches. It works by blocking the action of certain natural chemicals like adrenaline on the heart and blood vessels, reducing heart rate and blood pressure. Propranolol is also prescribed for anxiety, essential tremor, and certain types of thyrotoxicosis. It helps prevent complications like heart attacks, strokes, and kidney problems caused by hypertension.

Dosage and direction

Propranolol is usually taken orally 1 to 4 times daily, depending on the condition being treated. It should be taken at the same time each day, with or without food. Dosage is based on medical condition and response to treatment, and should be adjusted only under medical supervision. Do not stop taking propranolol suddenly, as it may worsen some conditions like angina.
