Plavix is a prescription drug used to prevent harmful blood clots from forming in people who have recently experienced a stroke, heart attack, or severe chest pain requiring hospitalization. The drug may also be used to prevent blood clots in people with very poor circulation. Plavix comes in the form of a tablet, which is normally taken once a day, with or without food. Common side effects of the drug include major bleeding, headaches, and dizziness.

What Is Plavix?

Plavix® (clopidogrel bisulfate) is a medication that is used to prevent harmful blood clots from forming in people who have had a recent heart attack, stroke, or severe chest pain requiring hospitalization.

Who Makes Plavix?

It is manufactured by Bristol-Myers Squibb in conjunction with sanofi-aventis Pharmaceuticals.

What Is It Used For?

Plavix is licensed to prevent blood clots from forming after having a heart attack, stroke, or chest pain that required hospitalization. It also works to prevent clots in people with very poor circulation, such as those who have peripheral artery disease (PAD). Preventing blood clots from forming and blocking blood vessels helps reduce the risk of having another related heart attack or stroke.

How Does It Work?

Plavix affects platelets, which are a type of blood cell that clump together to form clots and stop bleeding in the event of a cut or injury. It is part of a class of drugs called antiplatelet medications. Antiplatelet medications help prevent platelets (a type of blood cell) from sticking together and forming a potentially harmful clot. This helps your blood flow more easily.
