Why is this medication prescribed?

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 improve survival after a heart attack. Atenolol is in a class of medications called beta blockers. It works by relaxing blood vessels and slowing heart rate to improve blood flow and decrease blood pressure.

High blood pressure is a common condition and when not treated, can cause damage to the brain, heart, blood vessels, kidneys and other parts of the body. Damage to these organs may cause heart disease, a heart attack, heart failure, stroke, kidney failure, loss of vision, and other problems. In addition to taking medication, making lifestyle changes will also help to control your blood pressure. These changes include eating a diet that is low in fat and salt, maintaining a healthy weight, exercising at least 30 minutes most days, not smoking, and using alcohol in moderation.

How should this medicine be used?

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(s) 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.

What are the precautions to be followed?

Before taking atenolol,
  • tell your doctor and pharmacist if you are allergic to atenolol, any other medications, or any of the ingredients in atenolol tablets. Ask your pharmacist for a list of the ingredients.
  • tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking. Be sure to mention any of the following: calcium channel blockers such as diltiazem (Cardizem, Cartia XT, Dilacor XR, Tiazac, others) and verapamil (Calan, Covera-HS, Verelan, in Tarka); clonidine (Catapres, Kapvay, in Clorpres); nonsteroidal anti-inflammatory drugs (NSAIDs) such as indomethacin (Indocin, Tivorbex); and reserpine. Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
  • tell your doctor if you have or have ever had asthma or other lung diseases; diabetes; severe allergies; hyperthyroidism (an overactive thyroid gland); pheochromocytoma (a tumor that develops on a gland near the kidneys and may cause high blood pressure and fast heartbeat); heart failure; a slow heart rate; circulation problems; or heart or kidney disease.
  • tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking atenolol, call your doctor immediately.
  • if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking atenolol.
  • you should know that if you have allergic reactions to different substances, your reactions may be worse while you are using atenolol, and your allergic reactions may not respond to the usual doses of injectable epinephrine.
