Repatha injection is a cholesterol-lowering treatment designed for individuals with cardiovascular disease or inherited high cholesterol. Administered subcutaneously using a SureClick autoinjector or pre-filled syringe, it offers a convenient way to manage LDL (bad) cholesterol levels. Repatha works by inhibiting a protein called PCSK9, which allows the liver to remove more LDL from the bloodstream. Taken every two weeks or once monthly, this injection supports long-term heart health and reduces the risk of heart attacks and strokes.
