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 succeed you may have to change the way you feel about food and about your body.
XENICAL At Work
If you eat an excessive amount of fat or calories, the excess is stored as fat by the body, resulting in weight gain. When you eat fat, your body breaks it down into its simplest components so that it can be digested.
Unlike other weight-loss drugs you may have heard about that act in the brain or central nervous system to suppress appetite or to speed up metabolism, XENICAL works in your digestive system to block about one-third of the fat in the food you eat from being digested.
Enzymes in your digestive system, called lipases, help digest (or break down) fat. When taken with meals, XENICAL attaches to the lipases and blocks them from breaking down some of the fat you have eaten.
The undigested fat cannot be absorbed and is eliminated in your bowel movements. By working this way, XENICAL helps block about one-third of the fat in the foods you eat from being absorbed by your body.
Taking XENICAL
The recommended dose is one 120-mg capsule by mouth with liquid at each main meal that contains fat. You should take XENICAL up to three times a day in conjunction with a reduced-calorie diet. Each time you take XENICAL, your nutritionally balanced meal should contain no more than about 30% of calories from fat. You should evenly divide your daily intake of fat, carbohydrates and protein over three main meals. Take XENICAL during meals or up to 1 hour after a meal. If you occasionally miss a meal or have a meal without fat, you can omit your dose of XENICAL. Doses above 120 mg three times daily have not been shown to provide an additional weight-loss benefit.
You should try to follow a healthy eating plan, such as the one developed by the American Heart Association. Following this eating plan will help you lose weight while decreasing some of the possible gastrointestinal effects you may experience while taking XENICAL.
If your daily calorie intake is: | The recommended daily grams of fat (in a 30% fat diet) are: | |
1200 | 40 | |
1400 | 47 | |
1600 | 53 | |
1800 | 60 | |
2000 | 67 |
XENICAL interferes with your body's absorption of some fat-soluble vitamins. Therefore, when you use XENICAL, you should take a daily multivitamin supplement that contains vitamins D, E, and K and beta carotene. Take your multivitamin once a day at least 2 hours before or after taking XENICAL, such as at bedtime.
