What is Atenolol used for? Did you know that according to the British Health Foundation, around a quarter of adults in the UK, or 14.4 million people, have high blood pressure?[1].

If left undiagnosed and untreated, high blood pressure can lead to life-threatening health conditions such as heart attacks, severe strokes, and kidney failure. Thus, it is critical to have regular health examinations. If you’ve been diagnosed with high blood pressure, you’ll be given drugs like Atenolol to help lower your blood pressure.

What is Atenolol used for?

Atenolol is a blood pressure medication that can be taken with or without other drugs. Lowering high blood pressure is critical for survival as hypertension can lead to deadly strokes, heart attacks, and kidney damage. This medicine is also used to treat angina (chest pain) and improve the chances of surviving a heart attack. Atenolol is a type of beta-blocker. It works by preventing some natural substances in your body from acting on your heart and blood arteries—this aids in lowering heart rate, blood pressure, and cardiac strain.[2]

Is Atenolol a beta blocker?

Yes, Atenolol belongs to the beta-blocker class of drugs. The medication is typically prescribed to treat elevated blood pressure and irregular heartbeats (arrhythmia). However, it can also prevent chest pain caused by angina. Atenolol is also sometimes taken to help with anxiety and migraine prevention. However, it is not officially approved for the treatment of these conditions. Other beta-blockers include propranolol tablets, which can help with anxiety.

If you have high blood pressure, Atenolol can help you avoid heart disease, heart attacks, and strokes in the future. You cannot obtain this medication without a prescription, and it is available in tablets or a liquid that you can swallow. It can also be administered through injection. However, this is generally done in a hospital. [3]

Is Atenolol safe?

After reviewing your medical history and ensuring no drug interactions, your doctor will assess whether or not Atenolol is safe for you. Here are some conditions in which Atenolol can be unsafe:

Diabetes: People with diabetes should avoid taking Atenolol since it may conceal key indicators of low blood sugar, such as shaking and an increased pulse rate. It’s impossible to detect dangerously low blood sugar levels without these signals.

Poor Circulation: When using Atenolol, symptoms of poor circulation in the feet and hands may become worse. Since Atenolol lowers blood pressure, an insufficient amount of blood may reach your hands and feet.

Hyperthyroidism: Atenolol may be responsible for concealing symptoms of hyperthyroidism, such as a rapid heartbeat. It can be life-threatening to stop using this medication without visiting a doctor.

Asthma or chronic obstructive pulmonary disease: Individuals with these health conditions should avoid taking Atenolol. A doctor can still prescribe it in minimal doses and under strict supervision. High doses of this drug may block certain types of beta receptors located in the respiratory tract that can cause breathing airways to narrow, worsening asthma or COPD.[4])
