Clopidogrel is which type of medication, and how many days before surgery should it be stopped?

• A. Antiplatelet; 5-7 days before surgery
• B. Antibiotic; 1 day before surgery
• C. Analgesic; 2 days before surgery
• D. Anticoagulant; 1 day before surgery

Answer: (A)

Clopidogrel is an antiplatelet medication that works by irreversibly blocking the P2Y12 receptor on platelets, which prevents platelet activation and aggregation. Because its effect lasts for the life of the platelet, normal platelet function only returns as new platelets are made. Since platelets live about 7 to 10 days, stopping clopidogrel about 5–7 days before a planned surgery allows enough new platelets to circulate, reducing the risk of surgical bleeding while balancing the risk of thrombosis. It’s not an antibiotic or an analgesic, and it isn’t an anticoagulant; those other categories have different mechanisms and timing considerations for perioperative management. In complex cases, the exact timing may vary based on the patient’s thrombotic risk and the type of surgery, but 5–7 days is the typical guideline for elective procedures.
