Clopidogrel is an antiplatelet medication that stops cells in the blood (platelets) from sticking together and forming a clot. In other words, clopidogrel acts as a blood thinner to make your blood flow through your veins more easily and prevent blood clots. Blood clots may cause heart attack, unstable angina, stroke, among other complications. That’s why clopidogrel is usually prescribed for people who have a higher risk of having those conditions, or for people who have had them before. This drug may be used as part of combination therapy. One of the most common clopidogrel drug combinations is with aspirin. This pairing is usually prescribed for patients that have undergone a coronary stent procedure. Your physician will decide if you are a candidate for both aspirin and clopidogrel. Ensure you mention aspirin consumption with your doctor.
