What does it do?

Low-dose aspirin is used to prevent clots forming in your blood. This reduces your chance of having a stroke or a heart attack.

How should you take it?

Take aspirin regularly as directed.
Swallow the coated tablets whole with a glass of water.
Dissolve the soluble tablets in a glass of water before taking.
Cardiprin® tablets may be dissolved in your mouth.

What if you forget a dose?

Should an occasional dose be missed it need not be taken later.

Can you take other medicines?

Some medicines available without a prescription may react with aspirin including:

  • anti-inflammatories, such as diclofenac (e.g. Voltaren®), ibuprofen (e.g. Nurofen®), or aspirin (e.g. Disprin®, in doses used for pain relief). These can also be found in some cold and flu medicines (e.g. Nurofen Cold and Flu®).
