What Effient is used for

Effient is used to prevent blood cells from clotting.
It contains the active ingredient, prasugrel.
It is used by people who have had a PCI (percutaneous coronary intervention) because of unstable angina or a heart attack.
PCI is a procedure where a balloon-tipped tube is used to open a blocked artery, with or without a stent being placed in the artery.
Effient belongs to the group of medicines called antiplatelet agents.
It works by reducing the ability of blood cells to clot. By preventing blood cells from clumping, it reduces the chances of blood clots forming (a process called thrombosis), thereby decreasing or even stopping blood supply to the heart muscle.
Effient is always taken with aspirin.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed this medicine for another use. If you want more information, ask your doctor.
