1. Why am I using Atenolol-AFT?
Atenolol-AFT contains the active ingredient atenolol. Atenolol-AFT belongs to a group of medicines called beta-blockers. It makes the heart beat slower and less forcefully reducing the amount of oxygen required by the heart and the volume of blood it has to pump. This results in lower blood pressure. It widens the blood vessels in the body, causing blood pressure to fall. It helps the heart to beat more regularly.
Atenolol-AFT is used to:
- lower high blood pressure (hypertension)
- prevent angina
- treat irregular heart rhythm or beat (arrhythmias)
- treat heart attacks, or reduce the risk of heart complications following a heart attack
Atenolol-AFT may be used alone or in combination with other medicines to treat your condition.
Atenolol-AFT may also be used in emergency situations or during surgery to treat a fast heart beat before, during or after surgery.
Hypertension:
Everybody has blood pressure. Blood pressure helps to move the blood around your body. Your blood pressure will change 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 to know if you have hypertension. There are usually no symptoms with hypertension and you may feel fine. If hypertension is not treated, serious health problems e.g. stroke, heart disease and kidney failure may occur. Atenolol-AFT helps to lower your blood pressure.
Angina
Angina is a discomfort or pain felt in your chest. The pain may also be felt in your arms or neck and sometimes your shoulders and back. It may be caused by not enough oxygen or blood reaching areas of your heart. Angina pain is often caused by exercise or stress.
Atenolol-AFT is used to prevent angina. It is not used to relieve a sudden attack of angina.
Irregular heart beat (arrhythmia):
Some heart diseases, an over active thyroid gland or chemical imbalances may cause your heart to have an irregular heart beat or rhythm.
Atenolol-AFT helps restore your heart's normal rhythm.
Reducing heart complications after heart attack:
After a heart attack, you may have complications e.g. an irregular heart beat or an increased chance of having another heart attack.
Atenolol-AFT helps to prevent these complications from occurring.
Ask your doctor if you have any questions about why Atenolol-AFT has been prescribed for you.
Your doctor may have prescribed Atenolol-AFT for another reason.
Atenolol-AFT is not recommended for use in children as there have been no studies on its effects in children.
There is no evidence that Atenolol-AFT is addictive.
2. What should I know before I use Atenolol-AFT?

- other beta-blocker medicines
- medicines used to treat high blood pressure or angina
- medicine used to treat heart problems
- insulin and tablets used to treat diabetes
- medicines used to treat arthritis, pain, or inflammation
If any of these medicines and Atenolol-AFT are taken together, you may need to take different amounts of your medicine, or you may need to take different medicines.
Your doctor will advise you on which medicines to be careful with or to avoid while taking Atenolol-AFT.
During treatment, you may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?
Pregnancy and breastfeeding
Check with your doctor if you are pregnant or intend to become pregnant.
Talk to your doctor if you are breastfeeding or intend to breastfeed.
Atenolol passes into breast milk and may therefore affect the breast-fed baby.
3. What if I am taking other medicines?

4. How do I use Atenolol-AFT?
How much to take
- Follow the instructions given to you by your doctor and pharmacist carefully. They may differ from the information contained in this leaflet. If you do not understand the instructions on the label, ask your doctor or pharmacist for help.
- Hypertension:
The usual dose is from 10 mL (50 mg) up to 40 mL (200 mg) of Atenolol-AFT daily. If your dose is 20 mL or less, take it once a day. If you need to take more than 20 mL, take half of your Atenolol-AFT in the morning and the other half in the evening.
- Angina or Irregular Heart Beat:
The usual dose is from 10 mL up to 20 mL taken as either a single dose or half the dose in the morning and half at night.
- Heart attack:
The usual dose is 10 mL of Atenolol-AFT daily. Some people e.g. the elderly or those with kidney problems, may require a lower dose.
If you have been taking tablets that contain atenolol, your doctor may wish to see you more often until they are certain that Atenolol-AFT is working in the same way as the tablets you have been taking. While there should be no problem switching from atenolol tablets to atenolol liquid (or from the liquid to the tablets) it is possible that some people may need to have their dose adjusted to achieve the same effect. If you have any concerns about how Atenolol-AFT is working for you, talk to your doctor. - Follow the instructions provided and use Atenolol-AFT until your doctor tells you to stop.
- Atenolol-AFT helps to treat high blood pressure, irregular heart beat, heart attacks and prevent angina but does not cure them. Do not stop taking without checking with your doctor first. Your doctor may want you to gradually reduce the amount of Atenolol-AFT you are taking. This should take place over a period of about 2 weeks before stopping completely. Do not stop suddenly, as this may worsen your condition.
When to take Atenolol-AFT
- It does not matter if you take your medicine before or after food. It is best to take your medicine at the same time everyday. This will help you remember when to take it.
If you forget to use Atenolol-AFT
Atenolol-AFT should be used regularly at the same time each day. If you miss taking your dose at the usual time, if it is less than six hours since you missed your dose, take it as soon as you remember, and then go back to taking Atenolol-AFT at the same time you would normally. If it is more than six hours since your last dose, skip the dose you missed and take your next dose when you would normally.
Do not take a double dose to make up for the dose that you missed.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints.
If you use too much Atenolol-AFT
If you think that you have used too much Atenolol-AFT, you may need urgent medical attention.
You should immediately:
- phone the Poisons Information Centre
(by calling 13 11 26), or - contact your doctor, or
- go to the Emergency Department at your nearest hospital.
You should do this even if there are no signs of discomfort or poisoning.
If you take too much Atenolol-AFT, you may feel faint or dizzy or you may find it difficult to breathe.
5. What should I know while using Atenolol-AFT?
Things you should do
- Make sure you attend all of your doctor's appointments so that your progress can be checked
- Tell all the doctors, dentists and pharmacists that are treating you that you are taking atenolol
- Tell your doctor immediately if you become pregnant while taking Atenolol-AFT
- Immediately tell your doctor if you have an allergic reaction to any foods, medicines or insect stings. Atenolol can cause allergic reactions to be worse and harder to treat
- If you have diabetes, check your blood sugar level regularly and report any changes to your doctor. Atenolol-AFT may affect your diabetes. It may hide the symptoms of low blood sugar levels, e.g. a fast heart beat. It may take longer for your blood sugar level to get back to normal even if you follow the usual treatment for diabetes. Your diabetic medicines may have to be changed or the doses adjusted
- If you continue to have angina attacks, or have more of them whilst taking Atenolol-AFT, tell your doctor. Atenolol-AFT is used to help prevent angina, so your angina attacks should become less severe and occur less often
- If you feel light-headed, dizzy or faint when getting out of bed or standing up, get up slowly. You may feel light-headed or dizzy after taking Atenolol-AFT. This is because your blood pressure is falling suddenly. If this problem gets worse or continues, talk to your doctor. To help your body get used to the change in blood pressure, you may find the following useful:
- Stand up slowly when getting up from a chair or bed.
This will allow your body get used to the change in position and blood pressure
- If you feel dizzy, sit or lie down until you feel better
- If you feel faint, sit down and put your head between your knees - Drink lots of water when exercising and during hot weather when taking Atenolol-AFT. If you do not drink enough water while taking atenolol, you may feel faint, light-headed or sick.
- If you are having surgery (even at the dentist), tell your doctor or dentist that you are taking atenolol. Atenolol may affect some of the medicines used during surgery
- If you have to have any medical tests while you are taking Atenolol-AFT, tell your doctor. Atenolol may affect the results of some tests.
Remind any doctor, dentist or pharmacist you visit that you are using Atenolol-AFT.
Things you should not do
- Do not stop taking Atenolol-AFT without checking with your doctor
- Do not take any new medicines with Atenolol-AFT, unless your doctor has told you to
- Do not give Atenolol-AFT to anyone else, even if they have the same condition as you
- Do not use Atenolol-AFT to treat any other complaint unless your doctor tells you to
Things to be careful of
- Take care driving or operating machinery until you know how Atenolol-AFT affects you. Atenolol-AFT may cause dizziness, fatigue, light-headedness or faintness in some people.
- Be careful not to over exercise when you first start taking Atenolol-AFT. It helps prevent angina caused by physical activity and exercise. You may be tempted to exercise too much. Talk to your doctor about how much exercise you can do.
- Dress warmly during cold weather, especially if you will be outside for a long time e.g. when playing or watching sport in winter. Atenolol-AFT may make you more sensitive to cold temperatures, especially if you have circulation problems.
Beta-blockers tend to decrease blood circulation in the skin, fingers and toes.
