Clopidogrel

What it is for

Clopidogrel stops blood cells (platelets) clotting together in the arteries.

It is used for different reasons.

• If you have had a stent in a coronary artery, clopidogrel is used with aspirin, usually for up to 12 months, depending on the type of stent used.
• If you cannot take aspirin, clopidogrel can be used as an alternative.
• If you have had a heart attack, clopidogrel can be used with aspirin, usually for between four and 12 months, depending on the type of heart attack.

You should be given a card which tells you how long to take the clopidorgrel for.
