Full Consumer Medicine Information (CMI)

This leaflet provides important information about taking MINAX XL. You should also speak to your doctor or pharmacist if you would like further information or if you have any concerns or questions about using MINAX XL.
Where to find information in this leaflet:

1. Why am I taking MINAX XL?

MINAX XL contains the active ingredient metoprolol succinate. 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 MINAX XL has been prescribed for you.
Your doctor may have prescribed MINAX XL for another reason.

2. What should I know before I take MINAX XL?

When to take MINAX XL

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 MINAX XL

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 MINAX XL

If you forget to take a dose of MINAX XL, skip the dose you missed and take your next dose when you are meant to.
Do not take a double dose to make up for the dose you missed.
If you are not sure what to do or have trouble remembering when to take your medicine, ask your doctor or pharmacist for some hints.

If you take too much MINAX XL

If you think that you or anyone else has taken too much MINAX XL, urgent medical attention maybe needed.
You should immediately:
phone the Poisons Information Centre
(by calling 13 11 26) for advice, 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.

5. What should I know while taking MINAX XL?

Call your doctor straight away if you:

become pregnant while taking MINAX XL.
have a severe allergic reaction to foods, medicines or insect stings.
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.

Things you should do

Be sure to keep all of your doctor's appointments so that your progress can be checked.
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, tell your doctor immediately.
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.
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.
If you are about to be started on any new medicine, remind any doctor, dentist or pharmacist you visit that you are taking MINAX XL.
If you plan to have surgery (even at the dentist) that needs an anaesthetic, tell your doctor or dentist that you are taking MINAX XL.
If you have to have any medical tests while you are taking MINAX XL, tell your doctor. MINAX XL may affect the results of some tests.
MINAX XL may affect the results of some tests.
Tell any other doctors, dentists and pharmacists who treat you that you are taking this medicine.

Things you should not do

Do not stop taking MINAX XL 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.
Do not give MINAX XL to anyone else even if they have the same condition as you.
Do not use MINAX XL to treat any other complaints unless your doctor tells you to.

Driving or using machines

Be careful before you drive or use any machines or tools 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.

Drinking alcohol

Tell your doctor if you drink alcohol. Be careful drinking alcohol while you are taking MINAX XL.
If you drink alcohol, dizziness or light-headedness may be worse.

Heat and dampness can destroy some medicines.
