Repatha Auto Injector is a prescription medicine used to lower low-density lipoprotein (LDL) cholesterol. Its active ingredient is evolocumab. It belongs to the drug class known as PCSK9 inhibitors. It is administered as a subcutaneous injection and helps reduce the chances of a heart attack, stroke, and other cardiovascular issues. Repatha is mainly used in adults with high LDL cholesterol and in patients aged 10 years and older with homozygous familial hypercholesterolemia (HoFH). It works by helping the liver remove more harmful cholesterol from the blood, leading to better cholesterol control.

Repatha Auto Injector is FDA-approved for use in:
Repatha Auto Injector lowers cholesterol by blocking a protein in the body called PCSK9. PCSK9 normally reduces the number of LDL receptors in the liver. These receptors are important because they remove LDL cholesterol (the “bad” cholesterol) from the blood. When PCSK9 is blocked, more LDL receptors stay active. This allows the liver to clear more cholesterol from the bloodstream. The result is a strong reduction in LDL cholesterol levels.
