Plavix is used for:
Reducing the risk of stroke, heart attack, or death in patients who have already had a heart attack or stroke, have other circulatory problems caused by narrowing and hardening of the arteries, or have certain other heart problems (eg, unstable angina). It also may be used for other conditions as determined by your doctor.
Plavix is a platelet aggregation inhibitor. It works by slowing or stopping platelets from sticking to blood vessel walls or injured tissues.

- you are allergic to any ingredient in Plavix
- you have an active bleeding problem (eg, bleeding stomach ulcer, bleeding in the brain)

Contact your doctor or health care provider right away if any of these apply to you.
