Orlistat is used with an individualized low-calorie, low-fat diet and exercise program to help people lose weight.
Orlistat is also prescribed by doctors for overweight people who may also have high blood pressure, diabetes, high cholesterol, or heart disease.
Orlistat is also used after weight-loss to help people keep from gaining back that weight.
Orlistat is in a class of medications called lipase inhibitors. It works by preventing some of the fat in foods eaten from being absorbed in the intestines. This unabsorbed fat is then removed from the body in the stool.
