What Is Plavix Used For?
Plavix is a medication that helps prevent blood clots from forming in hardened blood vessels, a condition known as atherothrombosis. This can lead to serious health events such as stroke, heart attack, or even death.
Primary Uses
Plavix is primarily used to prevent blood clots in patients who have experienced a heart attack, stroke, or have peripheral arterial disease.
How It Works
Plavix works by preventing platelets in the blood from clumping together, which reduces the chances of clot formation.
