Why is this medication prescribed?

Prasugrel is used to prevent serious problems with heart and blood vessels in certain people who have had a heart attack or severe chest pain. Prasugrel is in a class of medications called anti-platelet medications. It works by preventing platelets (a type of blood cell) from collecting and forming clots that may cause a heart attack or stroke.

How should this medicine be used?

Prasugrel comes as a tablet to take by mouth. Take once a day with or without food. Take prasugrel at around the same time every day.

Take prasugrel exactly as directed. Ask your doctor or pharmacist to explain any part you do not understand. Do not take more or less of it or take it more often than prescribed by your doctor.

Swallow the tablet whole; do not split, break, chew, or crush it.

You will probably need to take aspirin during your treatment with prasugrel.

Prasugrel will help prevent serious problems with your heart and blood vessels only as long as you take the medication. Do not stop taking prasugrel without talking to your doctor. If you stop taking prasugrel, there is a higher risk that you may have a heart attack, develop a blood clot, or die.
