What this medicine is

used for

The name of your medicine is

Chemmart Atenolol. It contains the

active ingredient, atenolol.

Atenolol is used to:

lower high blood pressure


prevent angina (chest pain or

complications following a heart



All people have blood pressure. This

pressure helps to push blood all

around your body. Your blood

pressure changes 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 of knowing that you

have hypertension. There are usually

no symptoms and you may feel fine.

If hypertension is not treated, serious

health problems such as stroke, heart

disease and kidney failure may occur.

Atenolol helps to lower your blood



Angina is a pain or uncomfortable

feeling in the chest, often spreading

to the arms or neck and sometimes to

the shoulders and back. This may be

because there is not enough blood

and oxygen getting to the heart. The

pain of angina is usually brought on

by exercise or stress, but can also

occur at rest.

Atenolol helps prevent angina. It is

not used to relieve a sudden attack of


Irregular heart beat (arrhythmia):

Irregular heartbeat, also known as

arrhythmia, means that there is a

disturbance of the heart's normal

rhythm or beat. Arrhythmias may be

caused by a number of factors,

including some heart diseases, an

overactive thyroid gland, or chemical


Atenolol helps restore your heart's

normal rhythm.

Reducing heart complications after

heart attack:

After a heart attack, you may have

complications such as an irregular

heart beat or an increased chance of

having another heart attack.

Atenolol helps to prevent these

complications from occurring.

Ask your doctor if you have any

questions about why this medicine

has been prescribed for you.

Your doctor may have prescribed this

medicine for another reason.

How it works

This medicine contains atenolol.

Atenolol belongs to a group of

medicines called beta-blockers. It

decreases the heart's need for blood

and oxygen and therefore reduces the

amount of work the heart has to do. It

widens the blood vessels in the body,

causing blood pressure to fall. It also

helps the heart to beat more


There is no evidence that this

medicine is addictive.

It is available only with a doctor's

affect your ability to drive a car or

operate machinery, but make sure

If you do not understand the

instructions on the label, ask your

doctor or pharmacist for help.

How much to take

not you are taking any other



The usual dose is from 50mg (1

tablet) up to 200mg (4 tablets) of

designed to remind you when to take

this medication. To do this, take your

first dose from the position marked

"First Day ". On the following day

take the first tablet which is labelled

with the appropriate day. When you

have taken all doses in this pack, take

your next atenolol prescription in the

same way.

time each day will have the best

effect. It will also help you remember

when to take it.

It does not matter if you take it

Keep taking it until your doctor

tells you to stop.

irregular heartbeat, and heart attacks

and prevent angina but does not cure

Make sure you have enough tablets

to last over weekends and holidays.

without checking with your doctor.

Your doctor may want you to

gradually reduce the amount of

atenolol 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.

If you forget to take it

If you forget to take one or more

doses of atenolol, and 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 medicine as you would


Do not take a double dose to make

up for the dose that you missed. Do

not take any more than your

doctor prescribed for you.

This may increase the chance of you

getting an unwanted side effect.

If you are not sure what to do, ask

your doctor or pharmacist.

If you have trouble remembering

to take your medicine, ask your

pharmacist for some hints.

If you take too much


Immediately telephone your doctor

or the Poisons Information Centre

may have taken too much atenolol.

Do this even if there are no signs of

discomfort or poisoning.

You may need urgent medical


If you take too much atenolol, you

may faint, feel dizzy or light-headed,

While you are taking

this medicine

Things you must do

Always follow your doctor's

instructions carefully.

Keep all of your doctor's

appointments so that your progress

can be checked.

Tell any other doctors, dentists and

pharmacists who are treating you

that you are taking atenolol.

Tell your doctor immediately if

you become pregnant while taking



If you are about to start taking a

new medicine, remind your doctor

and pharmacist that you are taking


If you are going to have surgery

(even at the dentist), tell your

surgeon, anaesthetist or dentist

that you are taking atenolol.

Atenolol may affect some of the

medicines used during surgery, or

may cause your blood pressure to

drop suddenly.

If you have to have any medical

tests while you are taking atenolol,

tell your doctor.

Atenolol may affect the results of

some tests.

Drink lots of water when

exercising and during hot weather

when taking atenolol, especially if

you sweat a lot.

If you do not drink enough water

while taking atenolol, you may feel

faint, light-headed or sick. The

recommended healthy minimum

water intake is 6-8 glasses a day.

Tell your doctor immediately if

you have an allergic reaction to

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 may affect your diabetes. It

may hide the symptoms of low blood

sugar levels, such as a fast heart beat.

It may also 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

If you keep having angina attacks,

or have more of them whilst taking

atenolol, tell your doctor.

Atenolol is used to help prevent

angina, so your angina attacks should

become less severe and occur less


Things you must not do

Do not stop taking your medicine,

or lower the dosage, without

checking with your doctor.

Do not take any new medicines

with atenolol, unless your doctor

has told you to.

Do not take your medicine to treat

any other complaints unless your

doctor or pharmacist tells you to.

Do not give this medication to

anyone else, even if their symptoms

seem similar to yours.

Things to be careful of

As with other beta-blockers, atenolol

may cause dizziness or light-

headedness in some people,

especially after the first dose, or after

your dose is increased. . This is

because your blood pressure is

dropping suddenly.

If this problem gets worse or

continues, talk to your doctor.

To help your body get used to the

change in blood pressure, the

following hints may be 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


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.

Be careful driving or operating

machinery until you know how

atenolol affects you.

As with other beta blocker

medicines, atenolol may cause

dizziness, faintness, fatigue or light-

headedness in some people. Make

sure you know how you react to

atenolol before you drive a car,

operate machinery, or do anything

else that could be dangerous if you

are dizzy or light-headed. If you have

any of these symptoms stop driving,

operating machinery or performing

dangerous tasks.

If you drink alcohol, dizziness or

light-headedness may be worse.

Be careful not to over-exercise

when you first start taking


Atenolol helps prevent angina

resulting from 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 (for example, when

playing or watching sport in


Atenolol, like other beta-blocker

medicines, 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.

Things that would be helpful

for your blood pressure

The suggestions below may help

your condition. Talk to your doctor

or pharmacist about these measures

and for more information.


Your doctor may advise you to limit

your alcohol intake.

some weight to help lower your

blood pressure and help lessen the

amount of work your heart has to do.

Some people may need a dietician's

help to lose weight.

includes plenty of fresh vegetables,

fruit, bread, cereals and fish. Also eat

less fat and sugar.


Your doctor may advise you to watch

the amount of salt in your diet. To
