What is Praluent Pen?
Praluent Pen is a human monoclonal antibody. It works by helping the liver reduce levels of "bad" cholesterol (low-density lipoprotein, or LDL) circulating in your blood.
Praluent Pen is used together with a low-fat diet and a "statin" medication in people with heterozygous familial hypercholesterolemia (an inherited type of high cholesterol). This condition can cause high blood levels of LDL cholesterol, and can also cause plaque to build up inside your arteries.
Praluent Pen may also be used for purposes not listed in this medication guide.
Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.
