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.
