Atenolol is used alone or in combination with other medications to treat high blood pressure. It also is used to prevent angina (chest pain) and treat heart attacks. Atenolol is in a class of medications called beta blockers. It works by slowing the heart rate and relaxing the blood vessels so the heart does not have to pump as hard.

Atenolol comes as a tablet to take by mouth. It is usually taken once or twice a day. To help you remember to take atenolol, take it around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take atenolol exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Atenolol controls high blood pressure and angina but does not cure them. It may take 1-2 weeks before you feel the full benefit of atenolol. Continue to take atenolol even if you feel well. Do not stop taking atenolol without talking to your doctor.

Atenolol is also used sometimes to prevent migraine headaches and to treat alcohol withdrawal, heart failure, and irregular heartbeat. Talk to your doctor about the possible risks of using this medication for your condition.

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
