What this medicine is used for
The name of your medicine is Blooms The Chemist Clopidogrel. It contains the active ingredient clopidogrel.
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).
Clopidogrel 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, 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.
There is no evidence that this medicine is addictive.
This medicine is available only with a doctor's prescription.
This medicine should not be used in children.

- liver or severe kidney problems
- a genetic condition which means that a certain enzyme (CYP2C19) in your liver works differently and can negatively affect 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)
- rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucosegalactose malabsorption
Tell your doctor if you are pregnant or plan to become pregnant or are breastfeeding. Your doctor can discuss with you the risks and benefits involved.
