Xenical is used as a weight loss treatment in people with a BMI of 30 or more, together with a healthy, balanced diet and regular exercise, as part of an overall weight-loss plan. BMI is calculated using your height and weight. Learn more about BMI.
Xenical prevents the absorption of some of the fat you eat. When taking it, you need to eat a well-balanced diet that is high in fruit and vegetables and with less than 30% of calories from fat. More fat in your diet will increase the side effects of this medicine. Your daily intake of fat, carbohydrates and protein should be spread out over 3 main meals.
In New Zealand, Xenical is available as capsules (120mg). Xenical can be purchased from pharmacies without a prescription. A pharmacist needs to ask you questions to make sure it is the best option for you and needs to record your name and address.
