Xenical (Orlistat) belongs to a class of medications known as anti-obesity agents, specifically gastrointestinal lipase inhibitors. When combined with a mildly reduced-calorie diet that contains no more than 30% of calories from fat, Xenical (Orlistat) is used to help obese people lose weight and maintain weight loss.

Lipase is an enzyme that is needed to breakdown dietary fats into fatty acids, which is the form of fat that gets absorbed. Xenical (Orlistat) blocks the action of lipase and therefore prevents dietary fat from being absorbed. At the recommended dose, Xenical (Orlistat) inhibits dietary fat absorption by approximately 30%.

Xenical (Orlistat) should only be used by people who have a body mass index (BMI) of 30 kg/m² or higher, or by people with a BMI of 27 kg/m² or higher with other health risk factors such as high blood pressure, Type 2 Diabetes, High Cholesterol, or large waist measurement. BMI is not a direct measure of fat and these guidelines do not apply to athletes and pregnant women.

BMI is calculated by dividing your body weight in kilograms by the square of your height in metres. For example, if you weigh 150 lbs (68 kg) and are 5 ft 8 in (1.73 m) tall, divide 68 by (1.73×1.73), or 2.99. The result is a BMI of 22.7 kg/m².

Xenical (Orlistat) can also be used in combination with diabetes medications to improve blood glucose control in overweight or obese people with type 2 diabetes whose blood glucose levels are inadequately controlled with diet, exercise, and diabetes medications (e.g., Glyburide, insulin, Metformin).

Xenical (Orlistat) may be available under multiple brand names and/or in several different forms. Any specific brand name of Xenical (Orlistat) may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of Xenical (Orlistat) may not be used for all of the conditions discussed here.

Your doctor may have suggested Xenical (Orlistat) for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking Xenical (Orlistat), speak to your doctor. Do not stop taking Xenical (Orlistat) without consulting your doctor.
