What is Atenolol?

Atenolol is a treatment for high blood pressure when other treatments, such as diuretics, have been ineffective. It is also used to treat some heart conditions including arrhythmia, angina and myocardial infarction.

You can only obtain Atenolol for high blood pressure on prescription. With Prescription Doctor's private online prescription service, our online prescriber can issue a prescription for Atenolol following a short online medical consultation.

Looking to buy Atenolol? With Prescription Doctor, our UK registered pharmacy can send your prescription drugs straight to your door via a discreet next-day delivery service. All you need to do is complete a short online questionnaire for our online prescriber to review. If our prescriber approves your order before 3pm, our UK pharmacy can dispatch the item to you the same day.

How Does Atenolol work?

Atenolol slows down your heart rate and reduces the strength of your heart beat, making it easier for your heart to pump blood around your body while lowering your blood pressure in the process.

Atenolol counteracts a hormone made by the adrenal glands called adrenaline. This hormone is usually released into the blood stream during fight-or-flight situations or exercise, when your body requires your heart to beat faster to keep up with the demand of your body. When adrenaline binds to certain receptors, it triggers the heart to beat faster and more forcefully.

As a result, the pressure inside the blood vessels increases, as more blood is pumped through the body.

By blocking the receptors and preventing the effects of adrenaline on the heart, the heart rate decreases and the strength of the contractions decreases. In turn, the pressure inside the blood vessels decreases.

How Do I Take Atenolol?

Atenolol is usually taken once or twice a day; your doctor will determine the correct dose for you. Those who must take Atenolol twice a day must try to leave 10 to 12 hours between doses if possible.

Because the first dose of Atenolol may cause you to feel dizzy, your doctor may advise you to take your first dosage before bed.

You should aim to take Atenolol at the same time each day.

You can take Atenolol with or without food as it is unlikely to upset the tummy. Atenolol tablets should be swallowed whole with a glass of water.

It is important to not abruptly stop taking Atenolol as this could make your condition worse. Speak to a doctor if you wish to stop taking it; they will recommend the safest way to come off it.

Always take Atenolol as prescribed by your doctor. If you are unsure how to take Atenolol, ask your doctor.

Side effects and cautions

All medicines carry the potential of causing side effects, though not everybody will experience them. It's important to remain vigilant of side effects or any changes to your condition during your course of treatment. We encourage you to read the patient information leaflet (PIL) enclosed with your medicine before taking your medicine.

Alternatively, you can view the leaflet online here.

Common side effects (may affect up to 1 in 10 people):

  • Aching muscles
  • Cold hands or feet
  • Diarrhoea
  • Fatigue
  • Nausea
  • Slow heart rate

Uncommon side effects (may afect up to 1 in 100 people):

  • Disturbed sleep

This is not an exhaustive list of side effects. Further information about the safety of Atenolol, including a complete list of side effects, can be found within the patient information leaflet enclosed with your medicine.

If you experience any side effects, whether they are listed above or in the patient information leaflet, inform your doctor or speak to a pharmacist for advice.


Do not take Atenolol if you are allergic to atenolol or any of the other ingredients listed in the patient information leaflet.

If you experience the signs of an allergic reaction after taking Atenolol, stop taking the medicine and inform your doctor straight away. For severe allergic reactions, such as suspected anaphylaxis, go straight to the nearest casualty department. Remember to take the packaging and any remaining medicine with you so that doctors know exactly what you have taken.

Signs of an allergic reaction include:

  • Chest tightening
  • Dry, red and cracked skin
  • Itchy, red watery eyes
  • Raised, itchy, red rash (hives)
  • Swelling of the lips, tongue, eyes or face
  • Tummy pain, nausea, vomiting or diarrhoea
  • Wheezing

Pregnancy and breastfeeding

Atenolol is not usually recommended for pregnant women. If you are pregnant, think you might be pregnant or planning on having a baby, speak to your doctor about Atenolol. They may prescribe an alternative treatment for you.

It is known that Atenolol does pass through breast milk in small amounts, though it is unlikely to affect your baby.

In either case, you should discuss with your doctor the safety of any medicine you are taking.

Other safety information

Always seek your doctor's advice before you buy Atenolol online.

Please inform our doctor of all medication you are currently taking, including those prescribed by your doctor or bought over-the-counter, such as dietary and health supplements.

Do not take Atenolol past the expiry date printed on the packaging. The date refers to the last day of that month.

Never throw away medicine via household or water waste. Take any unwanted or expired medication to your local pharmacy and ask them to dispose of them safely on your behalf.

Always store medicine out of sight and reach from children and pets.

Never share your medicine with anyone else, even if they are experiencing the same symptoms or have been diagnosed with the same condition as you.

Getting the most out of treatment

Taking a prescription medication isn't the only thing you can do to help manage or lower your high blood pressure.

You should look towards changes to your diet and lifestyle in addition to your blood pressure lowering medication.

Eat a healthy balanced diet which is low in fat and sugar. Make sure you eat at least 5 portions of fresh fruit and vegetables by incorporating them into your meals. Avoid foods rich in saturated fats and limit your salt intake to no more than 6 grams per day.

Try to fit physical activity into your daily life by making small changes to your day to day activities. For example, if you get the bus, get off a stop earlier and walk the rest of the way. Take the stairs instead of using the lift or escalator. Go for a jog around your local park on the weekends. These small changes can make a difference to your overall health.

Being overweight can raise your blood pressure, so losing weight can make a difference to your condition.

Avoid beverages rich in caffeine and alcohol. Drinking excessive amount of alcohol on a regular basis can increase your blood pressure over time. Caffeine, found in tea, coffee, cola and energy drinks, can also raise your blood pressure.

Quitting smoking should be considered if you have high blood pressure. While smoking doesn't directly cause high blood pressure, it does put you at a higher risk of a heart attack or stroke.

Frequently Asked Questions

What should I do if I forget to take Atenolol when I should?

If you forget to take your daily dose of Atenolol, take it as soon as you remember unless it is near the time for your next dose. If this is the case, skip the missed dose and continue to take your next dose as usual. Do not double-dose to make up for the dose you missed.

If you regularly forget to take your medicine when you are supposed to, you may want to set an alarm on your phone or a smart home device to remind you. Speak to your pharmacist for more advice on how to help you remember.

What should I do if I take too much Atenolol?

If you accidentally take more Atenolol than prescribed by your doctor, go straight to A&E as soon as possible.

Do not drive yourself; get someone to take you there. Take your medication box, leaflet and any leftover tablets with you so that doctors know exactly what and how much you have taken.

Can I drink alcohol while taking Atenolol?

Alcohol can affect the blood pressure lowering effects of Atenolol. During your first few days of taking Atenolol it is best to avoid alcohol altogether until you see how the medication affects you. If Atenolol makes you feel dizzy, it is best to avoid drinking alcohol.

Will Atenolol impact my ability to drive or operate machinery?

Atenolol can make some people feel dizzy particularly when they first start taking it or after taking a bigger dose. In these situations it is best to avoid driving, riding a bike, using tools or operating heavy machinery until you feel that it is safe for you to do so.

How long does Atenolol take to work?

It may take up to 2 weeks before the effects become noticeable. Your doctor will likely review your progress with Atenolol to determine how effective the treatment is for you.

Will Atenolol affect my contraceptive?

Your contraceptive should not be affected by taking Atenolol. However, some hormonal contraceptives are not recommended for women with high blood pressure. For further information, speak to your doctor.
