Welcome to XENICAL.com!

XENICAL is a prescription medication that can help considerably overweight people lose weight and keep it off. We know that managing your weight can be frustrating, and sometimes you need a little extra support. Support you can't find in a pill alone. To help you succeed you may have to change the way you feel about food and about your body.

To determine if you may be a candidate for XENICAL, your doctor will check your Body Mass Index (BMI) -- a measure of weight which takes height into account. To find out your BMI now, use the convenient calculator below.

XENICAL may be right for you if you are considerably overweight (at least 30% above ideal weight or a body mass index of 30 or greater). XENICAL may also be right for you if you are overweight (at least 20% above ideal weight or a BMI of 27 or greater) and also have other risk factors such as high blood pressure, high cholesterol, or diabetes.

The BMI calculator is for informational purposes only, and calculations performed with this software should be verified and should not be solely relied upon when making treatment decisions. Please also see the BMI table in the XENICAL Important Patient Information.
