What Atenolol GH is used for

Atenolol GH belongs to a group of medicines called beta-blockers. It works by affecting the body's response to certain nerve impulses, especially in the heart. As a result, it decreases the heart's need for blood and oxygen and therefore reduces the amount of work the heart has to do. It widens the blood vessels in the body, causing blood pressure to fall. It also helps the heart to beat more regularly.

Atenolol GH is used to:

  • lower high blood pressure, which is called hypertension;
  • prevent angina
  • treat irregular heart rhythm or beat called arrhythmias;
  • treat heart attacks, or reduce your risk of heart complications following a heart attack.

Atenolol GH may be either used alone or in combination with other medicines to treat your condition.

Atenolol GH may also be used in emergency situations or during surgery to treat a fast heart beat before, during or after surgery.


Everyone has blood pressure. This pressure helps to push blood all around your body. Your blood pressure changes during the day, depending on how busy you are or how you are feeling.

You have hypertension (high blood pressure) when your blood pressure stays higher than is needed, even when you are calm and relaxed.

Regular blood pressure checks are the only way of knowing that you have hypertension. There are usually no symptoms of hypertension and you may feel fine. If hypertension is not treated, serious health problems such as stroke, heart disease and kidney failure may occur.

Atenolol GH helps to lower your blood pressure.


Angina is a discomfort or pain felt in your chest. The pain may also be felt down your arms or neck and sometimes your shoulders and back. This may be caused by not enough oxygen or blood reaching areas of your heart. Angina pain is often brought on by exercise or stress.

Atenolol GH is used to prevent angina. It is not used to relieve a sudden attack of angina.

Irregular Heartbeat (arrhythmia)

A number of factors such as some heart diseases, an over active thyroid gland or chemical imbalances may cause your heart to have an irregular heart beat or rhythm.

Atenolol GH helps restore your heart's normal rhythm.

Reducing Heart Complications After Heart Attack

After a heart attack, you may have complications such as an irregular heart beat or an increased chance of having another heart attack.

Atenolol GH helps to prevent these complications from occurring.

Ask your doctor if you have any questions about why it has been prescribed for you. Your doctor may have prescribed Atenolol GH for another reason.

Atenolol GH is not recommended for use in children, as there have been no studies of its effects in children.

There is no evidence that Atenolol GH is addictive.
