Clopidogrel (Plavix) Before Surgery
Clopidogrel (Plavix) is a strong antiplatelet. It's often paused before surgery — but the timing must be coordinated with your cardiologist.

Quick answer
Clopidogrel is usually stopped about 5–7 days before surgery to lower bleeding risk. But if you have a recent coronary stent, stopping it can cause a life-threatening clot — that decision must be made with your cardiologist, not alone.
Why it matters
Clopidogrel blocks platelets strongly, so it raises surgical bleeding risk more than aspirin does.
The catch: in people with a coronary stent, stopping clopidogrel too soon can cause the stent to clot off (stent thrombosis) — a medical emergency. So the stop date is a careful balance set by your heart doctor and surgeon together.
Do not stop without instruction
Never stop clopidogrel on your own if you have a coronary stent or recent heart attack. The timing must be agreed with your cardiologist.
What to ask your doctor
- Do I have a stent, and how recent is it?
- Has my cardiologist agreed the plan to stop clopidogrel?
- Exactly which day do I stop, and when do I restart?
- Do I need any substitute medication in the gap?

Frequently asked questions
How many days before surgery do I stop Plavix?
Often about 5–7 days, but only if your cardiologist agrees — stopping is risky with a recent stent.
Can I stop clopidogrel myself before surgery?
No. Coordinate with your cardiologist and surgeon, especially if you have a stent.
