About atenolol – what is atenolol?

What is Atenolol? 50 mg Atenolol is used for the treatment of high blood pressure (hypertension). Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. This medication is also used to treat chest pain (angina) and to improve survival after a heart attack. Atenolol side effect and atenolol dosing depend on your medical health.

Atenolol belongs to a class of drugs known as beta-blockers. It works by blocking the action of certain natural chemicals in your body, such as epinephrine, on the heart and blood vessels. This effect lowers the heart rate, blood pressure, and strain on the heart.

How to use Atenolol

  • Take this medication by mouth with or without food as directed by your doctor.
  • Usually 1 to 2 times daily.
  • It is best to avoid drinking apple/orange juice within 4 hours of taking atenolol.
  • Atenolol side effect and atenolol dosing depend on your medical health and response to treatment.
  • Use this medication regularly to get the most benefit from it.

To help you remember, take it at the same time(s) each day. Keep taking this medication even if you feel well. Most people with high blood pressure do not feel sick.

If this product is used for chest pain, it must be taken regularly to be effective. Use other medications (such as nitroglycerin placed under the tongue) to relieve chest pain as directed by your doctor.

It may take 1 to 2 weeks before you get the full benefit of atenolol dosing. Tell your doctor if your condition does not improve or if any atenolol side effect is worsened (for example, if your blood pressure readings remain high or increase if your chest pain occurs more often).
