While Repatha is generally well tolerated, there are some potential side effects that people should be aware of. The most common side effects of Repatha include upper respiratory tract infections. Less common but more serious side effects can include serious allergic reactions.

What is Repatha (evolocumab)?
Repatha is approved to:
- Treat adults with primary hyperlipidemia (high cholesterol), including those with heterozygous familial hypercholesterolemia (HeFH), alongside a healthy diet and may be used with other LDL-lowering treatments
- Reduce the risk of cardiovascular problems (such as heart attack and stroke) in adults with heart disease
- Treat adults and children aged 13 to 17 years with homozygous familial hypercholesterolemia (HoFH) with a healthy diet and other LDL-lowering treatments to lower cholesterol levels
Repatha works by blocking PCSK9, which means more receptors are available to remove LDL-C (low-density lipoprotein cholesterol) from the blood. This results in lower LDL cholesterol levels. LDL-C is sometimes described as bad cholesterol because it collects in the walls of the arteries leading to your heart. HDL (high-density lipoprotein cholesterol) is known as good cholesterol because it takes cholesterol away from the heart. Lowering LDL-C cholesterol reduces your risk of cardiovascular disease and reduction in blood cholesterol.
Repatha comes in liquid form in prefilled syringes that are given as a subcutaneous injection under the skin in your upper arm, thigh, or abdomen area.
Repatha can also be used as a SureClick autoinjector and as the Pushtronex system, which is a single-use, on-body infusor with prefilled cartridges.
You are advised to read the prescribing information provided with this medicine for the drug information and patient information, and always speak with your healthcare provider for medical advice about any changes to your dose so they can monitor and evaluate your condition.
