Clopidogrel is a medication that helps prevent blood clots. It is commonly prescribed for patients who have had a heart attack, stroke, or certain heart conditions. By inhibiting platelets in the blood from sticking together, it reduces the risk of serious cardiovascular events. This drug is often used in combination with other medications, such as aspirin, to enhance its effectiveness. Patients taking clopidogrel should follow their doctor's instructions carefully and be aware of potential side effects, including increased bleeding risk. Regular check-ups are important to monitor its effects on health.
