What is Juxtapid?

Juxtapid (lomitapide) is a cholesterol-lowering medication. It reduces blood levels of "bad" cholesterol, such as low-density lipoprotein (LDL) or non-high-density liproprotein (non-HDL), as well as a protein that carries bad cholesterol in the blood.

Juxtapid is used together with a low-fat diet and other treatments to lower total cholesterol in people with homozygous familial hypercholesterolemia (an inherited type of high cholesterol).

It is not known whether Juxtapid will lower your risk of heart disease.

Juxtapid is available only under a special program. You must be registered in the program and understand the risks and benefits of this medicine.
