Alirocumab is used by people who have blockage in the heart blood vessels to reduce the risk of heart attack, stroke, and certain types of chest pain that require treatment in a hospital. It is also used by people who have an inherited condition that causes high levels of LDL. Treatment with alirocumab, a proper diet, and cholesterol-lowering drugs can help lower "bad" cholesterol (LDL) in the blood. Alirocumab belongs to a class of drugs known as monoclonal antibodies. It works by improving how well your body gets rid of LDL cholesterol. In addition to eating a proper diet (such as a low-cholesterol/low-fat diet), other lifestyle changes that may help this medication work better include exercising, losing weight if overweight, and stopping smoking. Consult your doctor for more details.
