Full Consumer Medicine Information (CMI)
This leaflet provides important information about taking MINAX. You should also speak to your doctor or pharmacist if you would like further information
or if you have any concerns or questions about taking MINAX.
Where to find information in this leaflet:
1. Why am I taking MINAX?
MINAX contains the active ingredient metoprolol tartrate. MINAX belongs to a group of medicines called beta-blockers.
MINAX is used to:
lower high blood pressure, also called hypertension
prevent angina (chest pain)
treat or prevent heart attacks, or reduce your risk of heart complications following
a heart attack
prevent migraine headaches
It works by changing 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 widens the blood vessels in the body,
as well as helping the heart to beat more regularly.
Your doctor will have explained why you are being treated with MINAX and told you
what dose to take. MINAX may be used either alone or in combination with other medicines
to treat your condition.
Ask your doctor if you have any questions about why MINAX has been prescribed for
you.
Your doctor may have prescribed MINAX for another reason.
Follow all directions given to you by your doctor carefully.
They may differ from the information contained in this leaflet.
2. What should I know before I take MINAX?

under Section
6. Are there any side effects?
Pregnancy and breastfeeding
Check with your doctor if you are pregnant or intend to become pregnant.
Like most beta-blocker medicines, MINAX is not recommended for use during pregnancy.
Talk to your doctor if you are breastfeeding or intend to breastfeed.
The active ingredient in MINAX passes into breast milk, hence there is a possibility
that the breastfed baby may be affected.
Children and adolescents

taking MINAX.
3. What if I am taking other medicines?
Tell your doctor or pharmacist if you are taking any other medicines, including any
medicines, vitamins or supplements that you buy without a prescription from your pharmacy,
supermarket or health food shop.
Some medicines may interfere with MINAX and affect how it works. These include:
other beta-blocker medicines, including beta-blocker eye drops
calcium channel blockers or calcium antagonists, medicines used to treat high blood
pressure and angina, for example verapamil or diltiazem
medicines used to treat high blood pressure, for example clonidine, hydralazine, and

Your doctor and pharmacist have more information on medicines to be careful with or
avoid while taking MINAX.
Check with your doctor or pharmacist if you are not sure about what medicines, vitamins

4. How do I take MINAX?
Follow all directions given to you by your doctor or pharmacist carefully.
They may differ from the information contained in this leaflet.
How much to take
For high blood pressure:
The usual starting dose is one 50 mg or 100 mg tablet once a day for one week.
The dose is then usually increased to 50 mg or 100 mg once or twice daily.
Your doctor may tell you to take a different amount of MINAX.
Follow your doctor's instructions carefully.
If you are taking other prescription medicines which lower blood pressure, your doctor
may need to change the dose of them to obtain the best results for you.
For angina pectoris:
The usual dose is one 50 mg or 100 mg taken two or three times a day.
After myocardial infraction (heart attack):
The usual dose is 100 mg taken twice a day, often starting with a lower dose for 2
days.
For migraine prevention:
The usual dose is 50 mg to 75 mg taken twice a day (100 mg to 150 mg a day), taken
in divided doses morning and evening.
Ask your doctor or pharmacist if you are unsure of the correct dose for you.
They will tell you exactly how much to take.
How to take MINAX
Swallow the tablets with a glass of water.
MINAX tablets can be divided in half along the break-line, if your doctor has prescribed
half a tablet.
When to take MINAX
Take your medicine at about the same time each day before or after food.
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
Continue taking your medicine for as long as your doctor tells you. 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 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
If it is almost time for your next dose (within 6 hours), skip the dose you missed
and take your next dose when you are meant to.
Otherwise, take the missed dose as soon as you remember, and then go back to taking
your tablets as you would normally.
Do not take a double dose to make up for the dose 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
If you think that you or anyone else has taken too much MINAX, urgent medical attention
may be needed.
You should immediately:
phone the Poisons Information Centre
(Australia telephone 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. You may
need urgent medical attention.
If you take too many MINAX tablets your blood pressure may drop too far. You will
feel faint or faint, and your heart rate will also slow down. You may also have nausea,
vomiting and convulsions. In extreme cases, serious heart and lung problems may occur.
5. What should I know while taking MINAX?
Things you should do
Be sure to keep all of your doctor's appointments so that your progress can be checked.
Elderly patients especially need to be monitored to stop their blood pressure falling
too far.
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. 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.
Make sure you drink enough water during exercise and hot weather when you are taking
MINAX especially if you sweat a lot.
If you do not drink enough water while taking MINAX, 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 may affect how well your diabetes is controlled. It may also cover up some of
the symptoms of low blood sugar (also called hypoglycaemia) such as a fast heartbeat.
MINAX 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 be started on any new medicine, remind your doctor and pharmacist
that you are taking MINAX.
Tell all the doctors, dentists and pharmacists who are treating you that you are taking
MINAX.
If you plan to have surgery (even at the dentist) that needs an anaesthetic, tell
your doctor surgeon, anaesthetist or dentist that you are taking MINAX.
MINAX interacts with certain general anaesthetics and may cause a sudden drop in blood
pressure.
If you have to have any medical tests while you are taking MINAX, tell your doctor. MINAX may affect the results of some tests.
Call your doctor straight away if you:
become pregnant while taking MINAX.
have a severe allergic reaction to foods, medicines, or insect stings.
If you have a history of allergies, there is a chance that MINAX may cause allergic
reactions to be worse and harder to treat.
Things you should not do
Do not stop taking MINAX suddenly, or lower the dose, without checking with your doctor.
Stopping MINAX suddenly may worsen your angina or cause other heart complications
to occur. Your doctor may want you to gradually reduce the amount of MINAX you are
taking before stopping completely.
Do not give MINAX to anyone else, even if they have the same condition as you.
Do not use MINAX 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
affects you.
As with other beta-blocker medicines, MINAX may cause dizziness, light-headedness,
tiredness, or drowsiness in some people. Make sure you know how you react to MINAX
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.
Combining MINAX and alcohol can make you more drowsy, dizzy or lightheaded.
Things to be careful of
Dress warmly during cold weather, especially if you will be outside for a long time
(for example when playing winter sports).
MINAX, like other beta-blocker medicines, may make you more sensitive to cold temperatures
especially if you have circulation problems.
Looking after your medicine
Keep your tablets in the original container until it is time to take them.
If you take MINAX out of the original container it will not keep well.
Store below 30°C.
Follow the instructions in the carton on how to take care of your medicine properly.

not store it:
in the bathroom or near a sink, or
in the car or on window sills.
Heat and dampness can destroy some medicines.
Keep it where young children cannot reach it.
A locked cupboard at least one-and-a-half metres above the ground is a good place
to store medicines.
When to discard your medicine
Do not use MINAX if the expiry date (EXP) printed on the pack has passed or if the
packaging is torn or shows signs of tampering.
If it has expired or is damaged, return it to your pharmacist for disposal.
