What Imdur is for

Imdur is used to prevent angina. Angina is a pain or uncomfortable feeling in the chest, often spreading to the arms or the neck and sometimes to the shoulders and back. This is caused by too little blood and oxygen getting to the heart.
The pain of angina is usually brought on by exercise or stress.
Imdur belongs to a group of medicines called nitrates.
Imdur works by relaxing the blood vessels, letting more blood and oxygen reach the heart.
Your doctor will have explained why you are being treated with Imdur and told you what dose to take.
Follow all directions given to you by your doctor carefully.
They may differ from the information contained in this leaflet.
However, your doctor may prescribe this medicine for another use. Ask your doctor if you want more information.
Imdur is not addictive.

medicines that you buy without a prescription from a pharmacy, supermarket or health food shop.

Using Imdur

How to take it

Take one Imdur tablet every day, at about the same time.
If your doctor tells you to take two 60mg Imdur tablets each day, take both tablets at the same time.
Taking Imdur tablets at 24 hour intervals makes sure they keep working properly.
Swallow Imdur tablets whole, with half a glass of water or other liquid e.g. fruit juice, milk. Do not chew or crush the tablets.
The 60mg tablet can be broken in half if care is taken not to crumble them.
Imdur tablets are designed to let the drug out over a number of hours. If they are crushed or chewed they won't work properly.
Imdur tablets are composed of a waxy substance that does not dissolve in the body. You may find the outer shell of the tablets in your bowel motions. The medication in them has already been absorbed by the body

If you forget to take it

If you forget to take a dose, take it as soon as you remember, as long as it is not more than 8 hours late.
If it is more than eight hours after you should have taken Imdur, wait until the right time the next day to take it.
Do not double the dose.
You may find that you will need to use the tablets or spray that your doctor has given you to use during angina attacks if you miss a dose of Imdur.
If you have trouble remembering when to take your medicine, ask your pharmacist for some hints.

Overdose

Telephone your doctor or the Poisons Information Centre (13 11 26), or go to casualty at your nearest hospital immediately if you think that you or anyone else may have taken too much Imdur even if there are no signs of discomfort or poisoning.
If you take too many Imdur tablets you will have a pulsing headache. You may also feel excited, flushed, have cold sweats, nausea (feeling sick) and vomit.

While you are using Imdur

Things you must do

Take Imdur regularly once every day.
If you don't you will be more likely to get attacks of angina.
Tell your doctor if you continue to get angina attacks, or they become more frequent, while you are taking Imdur.

Things you must not do

Do not use Imdur to relieve acute attacks of angina.
Your doctor will have given you other tablets or a spray to use when you get attacks of angina.
Do not take medicines known as phosphodiesterase type 5 inhibitor used to treat impotence (or erectile dysfunction) whilst on Imdur.
Do not stop taking Imdur unless you have discussed it with your doctor.
Do not use Imdur for any other complaints unless your doctor tells you to.
Do not give your medicine to anyone else, even if you have the same condition as you.

Things to be careful of

You will probably feel better when you start taking Imdur, but be careful not to overdo physical activities straight away.
You will need time to improve your physical fitness.
Be careful driving or operating machinery until you know how Imdur affects you.
Imdur may cause dizziness and fainting in some patients, especially when you first start to take it. Make sure you know how you feel when you are taking Imdur before you drive a car, operate machinery, or do anything else that could be dangerous if you are dizzy.
Be careful when drinking alcohol while you are using Imdur.
If you drink alcohol while you are taking Imdur, your blood pressure may drop, making you feel dizzy or faint.
Please talk to your doctor or pharmacist about these possibilities if you think they may bother you.

Side effects

Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking Imdur.
Imdur helps most people with angina, but it may have unwanted side-effects in a few people. All medicines can have side effects.
Sometimes they are serious, most of the time they are not. You may need medical treatment if you get some of the side effects.
Ask your doctor or pharmacist to answer any questions you may have.
Tell your doctor if you notice any of the following and they worry you:
headache
feeling faint
dizziness
fatigue
muscle tenderness or weakness, not caused by exercise.
Headache is the most common side effect while taking Imdur. It can occur at the beginning of treatment, but usually goes away after a few days.
These are all mild side effects of Imdur.
Tell your doctor if you notice anything else that is making you feel unwell.
Some people may get other side effects while taking Imdur.

After using it

Storage

Keep your Imdur tablets in the blister pack until it is time to take them.
If you take Imdur out of the blister pack it will not keep well.
Keep it in a cool dry place where the temperature stays below 30 degrees C.
Do not store it or any other medicine in the bathroom or near a sink.
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.
Do not leave it in the car on hot days.

Disposal

Ask your pharmacist what to do with any tablets you have left over if your doctor tells you to stop taking them, or you find that they have expired.
