Repatha Prefilled Syringe works by helping the liver reduce levels of "bad" cholesterol (low-density lipoprotein, or LDL) circulating in your blood.

Repatha Prefilled Syringe is used together with a low-fat diet and other cholesterol-lowering medications in people with homozygous or heterozygous familial hypercholesterolemia (inherited types of high cholesterol). These conditions can cause high blood levels of LDL cholesterol, and can also cause plaque to build up inside your arteries.

Repatha Prefilled Syringe is also used to help lower the risk of stroke, heart attack, or other heart complications in people with heart or blood vessel problems caused by plaque build-up or hardening in the arteries (also called atherosclerosis, or arteriosclerosis).

Repatha Prefilled Syringe may also be used for purposes not listed in this medication guide.
