Generic Name: clopidogrel

What is clopidogrel?

Clopidogrel keeps the platelets in your blood from coagulating (clotting) to prevent unwanted blood clots that can occur with certain heart or blood vessel conditions.

Clopidogrel is used to prevent blood clots after a recent heart attack or stroke, and in people with certain disorders of the heart or blood vessels.

Clopidogrel may also be used for purposes other than those listed in this medication guide.
