Clopidogrel is used alone or with aspirin to prevent serious or life-threatening problems with the heart and blood vessels in people who have had a stroke, heart attack, or severe chest pain. This includes people who have a percutaneous coronary intervention that may involve inserting coronary stents or who have coronary artery bypass grafting. Clopidogrel is also used to prevent serious or life-threatening problems with the heart and blood vessels in people who have a peripheral arterial disease.
