Additional Information
Xenical may decrease your body's absorption of some fat-soluble vitamins. To ensure adequate nutrition, your doctor may recommend taking a multivitamin that contain vitamins D, E, K, and beta-carotene. Take your vitamin supplement once a day, at least 2 hours before or after a dose of Xenical. Each time you take Xenical, your meal should contain no more than about 30% of calories from fat. Evenly divide your daily intake of fat, carbohydrates, and protein over three main meals a day. Talk to your doctor about following a healthy eating plan
Possible Side Effects
Stop taking Xenical and seek emergency medical attention if you experience a rare allergic reaction including shortness of breath; closing of your throat; swelling of your lips, tongue, or face; or hives. Other, less serious side effects are more likely to occur. Continue to take Xenical and talk to your doctor if you experience oily spotting, gas with discharge, an urgent need to go to the bathroom, oily or fatty stools, an oily discharge, an increased number of bowel movements, an inability to control bowel movements, or orange or brown colored oil in your stool. The bowel changes listed above are a natural effect of blocking fat and indicate that Xenical is working. They generally occur early in treatment, particularly after meals containing higher amounts of fat than are recommended. These symptoms are usually temporary and lessen or disappear as you continue treatment and keep to your recommended diet of meals containing 30% fat. Side effects other than those listed here may also occur. Talk to your doctor about any side effect that seems unusual or that is especially bothersome
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
You should take
a multivitamin supplement containing vitamins A, D, E, and K to ensure good nutrition. The supplement should be taken at least 2 hours before or after you take Xenical , such as at bedtime
If you miss a dose of Xenical , take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once
Ask your health care provider any questions you may have about how to use Xenical
OVERDOSE
Single doses of 800 mg XENICAL and multiple doses of up to 400 mg three times a day for 15 days have been studied in normal weight and obese subjects without significant adverse findings
Should a significant overdose of XENICAL occur, it is recommended that the patient be observed for 24 hours. Based on human and animal studies, systemic effects attributable to the lipase-inhibiting properties of orlistat should be rapidly reversible
