About Atenolol

Atenolol is a prescription beta-blocker, which blocks the actions of certain chemicals in your body on your heart and blood vessels. Beta-blockers help lower heart rate, blood pressure, and strain on the heart.

It's used to treat high blood pressure (hypertension) and chest pain (angina pectoris). It can also lower the risk of death after a heart attack.

Atenolol is the generic formula and it's also available by the brand name Tenormin.

Atenolol may be prescribed as a tablet. Be sure to follow the instructions on your prescription, as they can vary based on the formula and dose that you are prescribed by your doctor.

If you're prescribed Atenolol, talk to your doctor if you have any concerns or want to stop taking the medication. If you don’t complete your prescription, the beta-blocker may not fully treat your high blood pressure or chest pain.

Atenolol uses

There are several FDA-approved uses for Tenormin, but it may also be used off-label to treat other conditions. Your online physician may prescribe it for any of the following common reasons. It’s also possible that your doctor may prescribe it for other reasons not listed here. If you have questions about why a medication is prescribed, ask your online doctor or pharmacist.

    Tenormin is FDA-approved to treat high blood pressure and improve blood flow. Lowering blood pressure helps reduce your risk of strokes, heart attacks, and kidney disease.

  • Angina pectoris

  • Heart attack

    Tenormin is FDA-approved to reduce cardiovascular mortality in clinically stable patients who have experienced a suspected acute myocardial infarction (heart attack).

How to take atenolol
