Clopidogrel is taken by adults to prevent atherothrombosis, which can lead to atherothrombotic events (such as stroke, heart attack, or death).
Clopidogrel has been prescribed to help prevent blood clots and reduce the risk of these severe events in: Patients who have atherosclerosis, and have previously experienced a heart attack, stroke or have peripheral arterial disease, or have experienced unstable angina or myocardial infarction. For the treatment of this condition, a stent may have been placed in the blocked or narrowed artery to restore effective blood flow. Acetylsalicylic acid may also be given.
Patients who have experienced symptoms of transient ischemic attack or mild ischemic stroke. Acetylsalicylic acid may also be given within the first 24 hours.
Patients who have atrial fibrillation and cannot take oral anticoagulants (vitamin K antagonists). Clopidogrel plus acetylsalicylic acid should have been prescribed if oral anticoagulants cannot be taken and there is no risk of major bleeding.
