Frequently asked questions
Can I stop clopidogrel for surgery?
Only on your doctor’s/surgeon’s advice — stopping at the wrong time after a stent can cause a dangerous clot.
Clopidogrel vs aspirin?
Both prevent clots differently and are often used together for a period after heart events, then sometimes one alone. Your cardiologist decides.
