What is in this leaflet

It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.
All medicines have benefits and risks. Your doctor has weighed the risks of you taking Cardasa against the benefits expected for you.
If you have any concerns about taking this medicine, talk to your doctor or pharmacist.

What Cardasa is used for
Cardasa is an enteric coated low dose aspirin (100 mg) tablet.
Low dose aspirin helps reduce blood stickiness, the tendency of blood to clot. Cardasa may be useful if you are at risk of angina, transient ischaemic attacks (TIAs or mini-strokes), stroke (due to a blood clot) or heart attacks if you already have heart or blood vessel disease.
The amount of aspirin in Cardasa is much less than you would need to take for a headache or other pain. If you require medication for temporary relief of these symptoms, we suggest you take (paracetamol).
Cardasa is for use under medical supervision only.
Use in children
Cardasa is not recommended for use in children under 18 years of age. Consult a doctor before giving this medication to children or teenagers with chickenpox, influenza or fever.

How to take Cardasa
If you do not understand the instructions on the box, ask your doctor or pharmacist for help.
How much to take
Do not take more than the recommended dose.
The recommended dosage is one Cardasa tablet at the same time every day. Take your first tablet from the appropriately marked day, then follow the days consecutively.
If you have any concerns about how to use Cardasa, talk to the doctor or pharmacist.
How to take Cardasa
Take Cardasa with a glass of water. Cardasa should be swallowed whole, without crushing, chewing or breaking the tablet.
Cardasa can be taken with or without food. Food does not alter the effects of Cardasa.
Take Cardasa at the same time each day. This will help you to remember when to take your medicine.
If you forget to take it
If you forget a dose of Cardasa, take it as soon as you remember.
However, if the next dose is due within 12 hours, skip the missed dose. Take the next dose at the normal time.
Do not take a double dose to make up for the dose that has been missed. Using more than the prescribed dose can increase the chance of unwanted side effects.
If you take too much (overdose)
Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have taken too much Cardasa. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
Be sure to show the doctor the Cardasa pack.
If you have any concerns about this, talk to your doctor or pharmacist.
While you are taking Cardasa
Things you must do
You must swallow Cardasa tablets whole.
Cardasa has an enteric coating that prevents the aspirin from being released in your stomach. This reduces the chance of the aspirin upsetting your stomach. The aspirin is released lower down, in the intestines, where it is absorbed gradually in to the blood stream.
Things to be careful of
It is advisable to withdraw aspirin at least one week before surgery. Blood donors should cease all forms of aspirin at least a week before giving blood. Aspirin prolongs the time for blood to clot.
Be careful driving or operating machinery until you know how Cardasa affects you. Cardasa may cause dizziness or light-headedness in some people. Make sure you know how you react to Cardasa before you drive a car or operate machinery.
Tell your doctor or pharmacist as soon as possible if you do not feel well during or after taking Cardasa. Besides their main effect, medicines may have some unwanted effects. Unwanted effects do not always occur in every person.
Most unwanted effects following Cardasa are mild, and may disappear without stopping Carda
. However, some side effects may need medical treatment.
Tell the doctor or pharmacist about any effect which is troublesome or ongoing.
Events reported during treatment or following Cardasa which may have been related to the medicine are listed below.
Tell your doctor or pharmacist if you notice any of the following that are troublesome or ongoing:
More serious events
Tell your doctor or pharmacist immediately if you notice any of the following:
- Increased bleeding (e.g. bruising easily, nose bleeds)
- Itching or rashes
As with other medicines there is a very small risk of serious allergic reaction.
Contact your doctor immediately or go to the casualty department of your nearest hospital if you notice any of the following:
- Swelling of limbs, face, eyes, inside of nose, mouth or throat
- Shortness of breath, breathing or swallowing difficulties
- Hives, itching (especially of the hands or feet), reddening of skin (especially around the ears), or severe skin reactions
- Unusual tiredness or weakness that is sudden and severe
Other signs of allergy to aspirin may include:
- Asthma, rhinitis
- Swelling with fluid in tissues
- Redness, itchy rashes or pustular eruptions
Other rare events that have been reported with aspirin include:

In the doses of aspirin administered in Cardasa the risk of these adverse events appears to be small.
You should tell the doctor or pharmacist as soon as possible if any of these, or any other unusual events or problems occur during or after treatment with Cardasa.
Do not be alarmed by this list of possible side effects. You may not experience any of them.
