Full Consumer Medicine Information (CMI)
This leaflet provides important information about using DURIDE. 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 DURIDE.
Where to find information in this leaflet:
1. Why am I using DURIDE?
DURIDE contains the active ingredient isosorbide mononitrate. DURIDE belongs to a group of medicines called nitrates. These medicines work by widening
blood vessels, letting more blood and oxygen reach the heart.
DURIDE is used to prevent angina.
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 caused by too little
blood and oxygen getting to your heart. The pain of angina is usually brought on by
exercise or stress.
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.
This medicine is available only with a doctor's prescription.
This medicine is not addictive.
There is not enough information to recommend the use of this medicine for children.

for help.
How much to take
The usual dose is one tablet once a day.
Some patients may need a different dose.
Your doctor will decide the right dose for you.
How to take it
Swallow the tablets whole with half a glass of water.
DURIDE tablets can be broken in half if care is taken not to crumble them. Break the
tablet in half with care if your doctor has prescribed half a tablet.
Do not crush or chew the tablets.
DURIDE tablets are modified release tablets. This means that the medicine is released
into the blood over an extended period of time. If you crush or chew the tablets,
they will not work as well.
When to take it
Take your medicine at about the same time each day.
Taking it at the same 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 this medicine before or after food.
If your doctor tells you to take two tablets each day, take both tablets at the same
time.
How long to take it for
Continue taking your medicine for as long as your doctor tells you.
This medicine helps to control your angina but does not cure it. It is important to
keep taking your medicine even if you feel well.
If you forget to take DURIDE
If it is more than 8 hours since you should have taken your 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 normally.
Do not take a double dose to make up for the dose you missed.
If you miss a dose of DURIDE, you may get attacks of angina.
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 use too much DURIDE

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.

vomit.
5. What should I know while using DURIDE?
Things you should do

that you are taking DURIDE.
Tell any other doctors, dentists and pharmacists who treat you that you are taking
this medicine.
If you become pregnant while taking this medicine, tell your doctor immediately.
Keep all of your doctor's appointments so that your progress can be checked.
If you continue to have angina attacks, or if they become frequent while you are taking
DURIDE tell your doctor.
Things you should not do
Do not use DURIDE to relieve acute attacks of angina.
This medicine is used to prevent angina. Your doctor will have given you other medicines

Do not take DURIDE 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.

If you stop taking it suddenly, your angina may worsen, or you may have unwanted side
effects.
Things to be careful of
You will probably feel better when you start to take DURIDE but be careful not to
overdo physical activities straight away.
You will need time to improve your physical fitness.
If you feel light-headed, dizzy or faint when getting out of bed or standing up, get
up slowly.
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 continues
or gets worse, talk to your doctor.
Driving or using machines
Be careful before you drive or use any machines or tools until you know how DURIDE
affects you.
This medicine may cause dizziness, light-headedness or fainting in some people. If
any have any of these symptoms, do not drive, operate machinery or do anything that
could be dangerous.
Drinking alcohol
Be careful when drinking alcohol while taking DURIDE.
Combining DURIDE and alcohol can make you more sleepy, dizzy or lightheaded, due to
a drop in your blood pressure.
After using DURIDE
Be aware that the outer shell of the DURIDE tablet passes through the body. This does
not affect the way it works.
DURIDE tablets are made of a wax-like shell which does not dissolve in the body. After
the active ingredient, isosorbide mononitrate, has been absorbed into the body, you
may see this empty tablet shell in your faeces (bowel motions).
Looking after your medicine
Keep your tablets in the pack until it is time to take them.
If you take the tablets out of the pack they may not keep well.
Keep your tablets in a cool dry place where the temperature stays below 30°C.
Do not store DURIDE or any other medicine in the bathroom or near a sink. Do not leave
it on a window sill or in the car.
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.
Getting rid of any unwanted medicine
If your doctor tells you to stop taking this medicine, or the expiry date has passed,
ask your pharmacist what to do with any medicine that is left over.
6. Are there any side effects?

are taking DURIDE.

in some people. All medicines can have side effects. If you do experience any side
