Xenical

Xenical (orlistat) blocks some of the fat that you eat, keeping it from being absorbed by your body.

Xenical is used together with a reduced-calorie diet and weight maintenance to treat obesity in people with certain risk factors (such as diabetes, high blood pressure, and high cholesterol or triglycerides).

Xenical may also be used for purposes not listed in this medication guide.

It is dangerous to purchase Xenical on the Internet or from vendors outside of the United States. Medications distributed from Internet sales may contain dangerous ingredients, or may not be distributed by a licensed pharmacy. Samples of “Xenical” purchased on the Internet have been found to contain sibutramine (Meridia), a prescription weight loss medication that can have dangerous side effects in certain people.

Important information about Xenical

Do not take Xenical if you are pregnant. Weight loss is not recommended during pregnancy, even if you are overweight or obese. You should not take Xenical if you are allergic to orlistat, if you are pregnant, or if you have gallbladder problems or chronic malabsorption syndrome (an inability to absorb food and nutrients properly).

Before taking Xenical, tell your doctor if you have an underactive thyroid, a history of gallstones or pancreatitis, type 1 or type 2 diabetes, an eating disorder, liver or kidney disease, or if you take other weight-loss medications (prescription or over-the-counter).

Xenical should not be used by anyone age 12 to 18 without the advice of a doctor. Xenical should be used only by the person for whom it was prescribed. Never share Xenical with another person, especially someone who has a history of eating disorder. Keep the medication in a place where others cannot get to it.

Xenical is only part of a complete program of treatment that also includes diet, exercise, and weight control. Your daily intake of fat, protein, and carbohydrates should be evenly divided over all of your daily meals. Follow your diet, medication, and exercise routines very closely.

Avoid a diet that is high in fat. High-fat meals taken in combination with Xenical can increase your risk of unpleasant side effects on your stomach or intestines.
