What this medicine is used for
The name of your medicine is Chemmart Clopidogrel. It contains the active ingredient clopidogrel.
It is used to prevent blood clots forming in hardened blood vessels (a process known as atherothrombosis) which can lead to events such as stroke, heart attack or death.
You may have been prescribed clopidogrel because you have
- previously suffered a heart attack or stroke, or have a condition known as peripheral arterial disease (leg pain on walking or at rest).
- suffered acute coronary syndrome (either a severe type of chest pain called unstable angina, or a heart attack). In this case you may also be prescribed aspirin.
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.
This medicine is available only with a doctor's prescription.
How it works
Clopidogrel belongs to a group of medicines called anti-platelet medicines.
Platelets are very small blood cells which clump together during blood clotting. By preventing this clumping, anti-platelet medicines reduce the chances of blood clots forming (a process called thrombosis).
There is no evidence that this medicine is addictive.
Use in children
This medicine should not be used in children.

- You are hypersensitive to, or have had an allergic reaction to, clopidogrel or any of the ingredients listed at the end of this leaflet.
Symptoms of an allergic reaction may include: cough, shortness of breath, wheezing or difficulty breathing; swelling of the face, lips, tongue, throat or other parts of the body; rash, itching or hives on the skin; fainting; or hay fever-like symptoms.

- any illness or disability that was caused by bleeding, for example impaired sight or vision because of bleeding within the eye
- recent serious injury
- recent surgery (including dental surgery)
- any form of liver disease
- a genetic condition which means that a certain enzyme (CYP2C19) in your liver works differently and can negatively effect the amount of clopidogrel converting into its active form, resulting in reduced effects. Your doctor may perform a test for this condition and depending on results may change your dose or consider an alternative treatment option.
- allergy to other antiplatelet medicines (such as ticlopidine, prasugrel).
- You are currently pregnant or you plan to become pregnant. It is recommended that clopidogrel is not taken during pregnancy. Do not take this medicine whilst pregnant until you and your doctor have discussed the risks and benefits involved.
