What is in this leaflet
This leaflet answers some common questions about MINAX XL.
It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.

What MINAX XL is used for
MINAX XL belongs to a group of medicines called beta-blockers.
It works by affecting the body's response to some 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 also helps the heart to beat more regularly.
MINAX XL is used to treat heart failure - increase survival, reduce hospitalisation and improve symptoms. It is used in combination with other medicines to treat your condition.
Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.

When to take it
Take your medicine at about the same time each day, preferably together with the morning meal. Taking it at the same time each day will have the best effect. It will also help you remember when to take it.
How long to take it
Continue taking your medicine for as long as your doctor tells you to. This medicine helps to control your condition, but does not cure it. It is important to keep taking your medicine even if you feel well.
DO NOT STOP TAKING MINAX XL TABLETS SUDDENLY. The dose needs to be reduced slowly over 7 to 14 days to make sure that your condition does not get worse. Your doctor will tell you how to gradually reduce the dose before stopping completely.
If you forget to take it
If you miss a dose of MINAX XL and your next dose is more than 12 hours away, take the missed dose right away.
If your next dose is less than 12 hours away take only half the dose, take your next dose when you are meant to.
Do not take a double dose to make up for the dose that you missed.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering when to take your medicine, ask your pharmacist for some hints.
If you take too much (overdose)
Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have taken too much MINAX XL. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
If you take too many MINAX XL tablets, your blood pressure may drop too far. You will feel faint or may faint and your heart rate will also slow down. You may also have nausea, vomiting and shortness of breath. In extreme cases, serious heart and lung problems may occur.
While you are taking MINAX XL
Things you must do
If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking MINAX XL.
Tell any other doctors, dentists and pharmacists who treat you that you are taking this medicine.
If you are going to have surgery, tell the surgeon or anaesthetist that you are taking this medicine. Your blood pressure may drop suddenly if MINAX XL interacts with the anaesthetic.
If you become pregnant while taking this medicine, tell your doctor immediately.
If you have a severe allergic reaction to foods, medicines or insect stings, tell your doctor immediately. If you have a history of allergies, there is a chance that MINAX XL may cause allergic reactions to be worse and harder to treat.
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 when you begin to take MINAX XL. This is because your blood pressure has fallen suddenly.
Standing up slowly, especially when you get up from bed or chairs, will help your body get used to the change in position and blood pressure. If this problem gets worse or continues, talk to your doctor.
If you feel a worsening of your condition in the early stages of taking MINAX XL. Some people may experience an apparent worsening of their condition in the early stages of treatment with MINAX XL. It is important to tell your doctor if this happens to you, although it is usually temporary. If your condition continues to worsen, you should see your doctor as soon as possible.
Make sure you drink enough water during exercise and hot weather when you are taking MINAX XL, especially if you sweat a lot. If you do not drink enough water while taking MINAX XL, you may feel faint or light-headed or sick. This is because your blood pressure is dropping too much. If you continue to feel unwell, tell your doctor.
If you are being treated for diabetes, make sure you check your blood sugar level regularly and report any changes to your doctor. MINAX XL may change how well your diabetes is controlled. It may also cover up some of the symptoms of low blood sugar (hypoglycaemia). MINAX XL may increase the time your body takes to recover from low blood sugar. Your doses of diabetic medicines, including insulin, may need to change.
If you are about to have any blood tests, tell your doctor that you are taking this medicine. It may interfere with the results of some tests.
Keep all of your doctor's appointments so that your progress can be checked.
Things you must not do
Do not take MINAX XL to treat any other complaints unless your doctor tells you to.
Do not give your medicine to anyone else, even if they have the same condition as you.
Do not stop taking your medicine or change the dosage without checking with your doctor. Your doctor may want you to gradually reduce the amount of MINAX XL you are taking before stopping completely. This may help reduce the possibility of your condition worsening or other heart complications occurring.
Things to be careful of
Be careful driving or operating machinery until you know how MINAX XL affects you. As with other beta-blocker medicines, MINAX XL may cause dizziness, light-headedness, tiredness, or drowsiness in some people. Make sure you know how you react to MINAX XL before you drive a car, operate machinery, or do anything else that could be dangerous if you are dizzy or light-headed.
Be careful when drinking alcohol while you are taking this medicine. If you drink alcohol, dizziness or light-headedness may be worse.
Dress warmly during cold weather, especially if you will be outside for a long time (for example when playing winter sports). MINAX XL, like other beta-blocker medicines, tends to decrease blood circulation in the skin, fingers and toes. It may make you more sensitive to cold weather, especially if you have circulation problems.
Lifestyle measures that help reduce heart disease risk
By following these simple measures, you can further reduce the risk from heart disease.
- Quit smoking and avoid second-hand smoke.
- Limit alcohol intake.
- Enjoy healthy eating by:
- eating plenty of vegetables and fruit;
- reducing your saturated fat intake (eat less fatty meats, full fat dairy products, butter, coconut and palm oils, most take-away foods, commercially-baked products).
- Be active. Progress, over time, to at least 30 minutes of moderate-intensity physical activity on 5 or more days each week. Can be accumulated in shorter bouts of 10 minutes duration. If you have been prescribed anti-angina medicine, carry it with you when being physically active.
- Maintain a healthy weight.
- Discuss your lifestyle and lifestyle plans with your doctor.
- For more information and tools to improve your heart health, call Heartline, the Heart Foundation's national telephone information service, on 1300 36 27 87 (local call cost).

- You may also have difficulty breathing, or have a cold sweat or feel dizzy or light headed or feel like vomiting (or actually vomit).
