Consumer Medicine Information (CMI)
This leaflet provides important information about using BETALOC tablets. 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 BETALOC tablets.
Where to find information in this leaflet:
1. Why am I using BETALOC tablets?
BETALOC tablets contains the active ingredient metoprolol tartrate. BETALOC belongs to a group of medicines called beta-blockers.
BETALOC tablets are used to:
lower high blood pressure, also called hypertension
prevent angina
treat or prevent heart attacks, or reduce your risk of heart complications following
a heart attack
prevent migraine headaches
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 widens the blood vessels in the body,
as well as helping the heart to beat more regularly.
2. What should I know before I use BETALOC tablets?

or difficulty breathing; swelling of the face, lips, tongue or other parts of the

Like most beta-blocker medicines, BETALOC is not recommended for use during pregnancy.

The active ingredient in BETALOC passes into breast milk and therefore there is a
possibility that the breastfed baby may be affected.

pressure and angina, for example verapamil and diltiazem

Check with your doctor or pharmacist if you are not sure about what medicines, vitamins

4. How do I use BETALOC tablets?
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 BETALOC.
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 starting dose is one 50 mg or 100 mg taken two or three times a day.
After myocardial infarction (heart attack):
The usual starting dose is 100 mg taken twice a day, often starting with a lower dose
for 2 days.
For migraine prevention:
The usual dose is 100-150 mg taken twice 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 BETALOC
Swallow the tablet with a glass of fluid.
When to take BETALOC
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 BETALOC
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 BETALOC 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 use BETALOC tablets
If it is almost time for your next dose, skip the dose you missed and take your next
dose when you are meant to.
Otherwise, take it 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 use too much BETALOC tablets
If you think that you have used too much BETALOC tablets, 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. You may
need urgent medical attention.
If you take too many BETALOC tablets your blood pressure may drop too far. You will
feel 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 using BETALOC tablets?
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 BETALOC.
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
BETALOC, especially if you sweat a lot.
If you do not drink enough water while taking BETALOC, 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.
BETALOC may change how well your diabetes is controlled. It may also cover up some
of the symptoms of low blood sugar (hypoglycaemia). BETALOC may increase the time
your body takes to recover from low blood sugar. Your doses of diabetic medicines,
including insulin, may need to change.
Call your doctor straight away if you:
become pregnant while taking BETALOC
have a severe allergic reaction to foods, medicines or insect stings
If you have a history of allergies, there is a chance that BETALOC may cause allergic
reactions to be worse and harder to treat.
If you are about to be started on any new medicine, remind your doctor and pharmacist
that you are taking BETALOC.
Tell any doctors, dentists, and pharmacists who are treating you that you are taking
BETALOC.
If you plan to have surgery (even at the dentist) that needs an anaesthetic, tell
your doctor or dentist that you are taking BETALOC.
If you have to have any medical tests while you are taking BETALOC, tell your doctor.
BETALOC may affect the results of some tests.
Things you should not do
Do not stop using this medicine suddenly without checking with your doctor.
Your doctor may want you to gradually reduce the amount of BETALOC you are taking
before stopping completely. This may help reduce the possibility of your condition
getting worse.
Do not give BETALOC to anyone else even if they have the same condition as you.
Do not use BETALOC 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 BETALOC
affects you.
As with other beta-blocker medicines, BETALOC may cause dizziness, light-headedness,
tiredness, or drowsiness in some people. Make sure you know how you react to BETALOC
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.
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).
BETALOC, 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 blister pack until it is time to take them.
If you take BETALOC out of the blister pack it will not keep well.
Follow the instructions in the carton on how to take care of your medicine properly.
Store it in a cool dry place where the temperature stays below 30°C, away from moisture,
heat or sunlight; for example, do 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.
When to discard your medicine
Do not use BETALOC 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.
Getting rid of any unwanted medicine
If you no longer need to use this medicine or it is out of date, take it to any pharmacy
for safe disposal.
Do not use this medicine after the expiry date.
