Orlistat is used as an aid to help you lose weight. Xenical prevents the digestion of some of the fat you eat. Fats that are not digested cannot be absorbed and therefore do not contribute calories. To give the greatest weight loss, Orlistat must be used with a weight-reduction diet.
Xenical prevents the absorption of some of the fat you eat. Therefore, you should take it during the meal or within 1 hour of eating. If you occasionally miss a meal or eat a meal that contains no fat, you should skip the dose of Xenical.
Because Xenical 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.
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.
The dose of Xenical will be different for different patients. Follow your doctor’s orders or the directions on the label. The following information includes only the average doses of Xenical. If your dose is different, do not change it unless your doctor tells you to do so.
Adults – 120 milligrams (mg) three times a day with meals containing fat.
Children – Use and dose must be determined by your doctor.
Missed dose of Xenical:
If you are using Xenical regularly and you miss a dose, use it as soon as possible. Then use any remaining doses for that day at regularly spaced intervals. Do not double doses.
Storage – To store Xenical:
Keep out of the reach of children.
Store away from heat and direct light.
Do not store in the bathroom, near the kitchen sink, or in other damp places. Heat or moisture may cause the medicine to break down.
Keep the medicine from freezing. Do not refrigerate.
Do not keep outdated medicine or medicine no longer needed. Be sure that any discarded medicine is out of the reach of children.
