Xenical (Orlistat) is a weight loss aid used in combination with a low-calorie diet and doctor-approved exercise. It also helps to continue maintaining weight following weight loss. It is for use in adults only. Orlistat is used in patients with a certain weight who may also have high blood pressure, diabetes, high cholesterol, or heart disease.
Orlistat is in a class of drugs called lipase inhibitors. It works in your intestines, where it blocks some of the fat you eat from being absorbed and disgested. This undigested fat is then removed in your bowel movements (BM).
