Uses For Xenical

Orlistat is used together with a reduced-calorie diet to help you lose weight and to help keep the lost weight from returning. It is also used in overweight people who may also have diabetes, high blood pressure, high cholesterol, or heart disease.

Orlistat prevents the absorption of some of the fat you eat. Therefore, you should take it with liquids during the meal or up to one hour after eating. If you occasionally miss a meal or eat a meal that contains no fat, you should skip the dose of orlistat.

Because orlistat may decrease the amount of some vitamins that your body can absorb from food, you will need to take a multivitamin supplement once a day. Take the vitamin supplement at least 2 hours before or after taking orlistat. You may also take your multivitamin supplement at bedtime.

When using orlistat, your diet should contain no more than 30% of calories as fat. More fat in your diet will increase the side effects of this medicine. Your diet should be nutritionally balanced, and your daily intake of fat, carbohydrates, and protein should be distributed over three main meals.

Follow your doctor's instructions carefully on a reduced-calorie diet plan and regular exercise. Talk with your doctor before starting any exercise program.
