High Blood Pressure

Atenolol

Atenolol is a prescription medication used in the treatment of high blood pressure (hypertension). High blood pressure is when there is too much force of the blood pushing against the blood vessels as it pumps around the body, this can lead to serious health problems such as heart attacks and strokes. High blood pressure needs to be controlled and managed to prevent these complications. This condition is usually managed with medication or lifestyle changes such as exercising and having a more balanced diet, or a combination of the two. Atenolol belongs to a group of medicines called beta blockers which are commonly used in the treatment of hypertension. This medicine may also treat uneven heart beats, chest pain such as tightness in the chest, as well as protecting the heart in the early treatment of heart attacks.

How does atenolol work?

The active ingredient, atenolol, works by slowing down the heart beat to reduce the force of the heart pumping blood around the body and therefore lowers high blood pressure and eases the strain on the heart. It does this by blocking chemicals in the body which stimulate the heart which makes it beat faster, one of these chemicals is known as epinephrine. Blocking these chemicals slows fast and irregular heart beats and lowers blood pressure.

Who is suitable to take atenolol?

Atenolol may be suitable for adults who have been diagnosed with high blood pressure, or other conditions related to the heart, such as arrhythmias, angina pectoris, or myocardial infarction. In some cases this medicine may also be prescribed to babies and children.

Who is not suitable for atenolol?

Not everyone with high blood pressure will be suitable for this type of treatment and there are a number of reasons for this. Medicine is usually not suitable if a person has other health problems or is taking other medications which may interact with atenolol, or if a person is pregnant or breastfeeding. You should always consult your doctor if you’re taking other medication, have a health condition or have a history of certain conditions, or are pregnant, to ensure that this medicine is safe for you to take.

Atenolol and pregnancy

You should always ask your doctor for advice on the safest way to treat high blood pressure during pregnancy, high blood pressure still needs to be controlled during this time but it’s important that this is done in a way that doesn’t harm your baby. Atenolol is not usually recommended for women who are pregnant or planning to become pregnant but this can be discussed with your doctor. Atenolol is not likely to cause harm to your baby if you’re breastfeeding but your doctor will advise you on whether or not it’s safe for you to take while breastfeeding.

Atenolol and health conditions

Always ask a doctor if atenolol is suitable for you to take if you have other health conditions. This medicine may not be suitable if you have or have had other heart problems such as uncontrolled heart failure, second or third-degree heart block (you must also talk to your doctor about taking this medicine if you have first-degree heart block), very slow or very uneven heart beat, very low blood pressure, and very poor circulation. In these instances you mustn’t take atenolol.

You should also discuss your suitability for this medicine if you have any of the following health conditions:

  • A tumour called pheochromocytomav
  • Higher than normal levels of acid in your blood
  • Asthma, wheezing, or other breathing problems
  • A type of angina called Prinzmetal’s angina
  • Poor blood circulation
  • Diabetes
  • Thyrotoxicosis
  • Problems with your kidneys

If you have an allergy to atenolol or any other ingredient in this medicine you will not be suitable and you’ll need an alternative medicine to treat your high blood pressure.

Atenolol and other medication

When starting a new medication you should always check that it is safe to take with other medicines that you may currently be taking to avoid side effects and interaction between the drugs. Atenolol may interact with other drugs and affect how they work, or other drugs may affect how atenolol works. There are some medicines which you should be particularly aware of and consult with your doctor if you’re taking them alongside atenolol. These medicines include:

  • Medicine to treat high blood pressure and migraine called clonidine
  • Some medicines which treat high blood pressure and chest pain such as verapamil, diltiazem and nifedipine
  • Medicine to treat heart problems called digoxin
  • Adrenaline (epinephrine) which stimulates the heart
  • Ibuprofen or indometacin
  • Insulin or oral diabetes medicines
  • Medicines to treat nose or sinus congestion, or cold remedies
  • How to take atenolol

    Atenolol is available in tablet form and when first starting atenolol you will begin on a dose of 25mg which may be increased. The amount you take will also depend on what you’re taking it for and your current health condition. If you’re taking this medicine for hypertension the usual dose for adults is 100mg once a day or 50mg if you have kidney problems. The dose is similar for chest pain and heart rhythm disorders.

    What are the side effects of atenolol?

    As with any medication there are side effects, some are common and some are rare with only 1 in 1,000 people experiencing the rare side effects.

    How long will I need to take atenolol and is it effective at treating high blood pressure?

    How long you take atenolol for depends on what it is being used to treat. If it’s being used to treat high blood pressure then you’ll need to take atenolol for life or at least for a long period of time. Atenolol effectively keeps blood pressure under control and can take effect just 3 hours after taking the medicine. If taken consistently and correctly atenolol can reduce your blood pressure to a normal level and prevent the serious complications of this condition.

    Can atenolol treat migraines?

    Although it has not been officially approved to treat this condition, it has been known to prevent migraines and it has been prescribed for this reason. However, it’s not fully understood how atenolol helps migraines. You should discuss the use of this medicine in the treatment of migraines with your doctor.
