Xenical (orlistat) is a medication indicated for the treatment and management of obesity. Xenical therapy provides weight loss and weight control and is used in combination with other methods of weight management such as low calorie diet, physical activity and in some cases psychological counseling.
The other medical purpose of the medication is to lower the chance for weight gain after prior weight loss. Xenical restricts fats in a body and prevents them from being absorbed in the stomach. Obese patients with an initial body mass index (BMI) ?30 kg/m2 or ?27 kg/m2 are prescribed this medication to reduce and control weight.
Xenical is also used in people with obesity risk including patients with diabetes, hypertension, high triglycerides, dyslipidemia, high cholesterol levels and other conditions leading to overweight and obesity.
The usual recommended dose of Xenical is one capsule (120-mg) three times a day taken with meal containing fat. The doses higher than recommended three times a day will not bring any additional result.
A patient should discuss with a doctor his diet before using this medication, the diet should be nutritionally balanced, low in fats. The daily intake of all nutrients should be divided over main meals. If a person takes foods containing no fat, he/she should not use Xenical with it.
Xenical may decrease the absorption of certain fat-soluble vitamins so in some cases patients have to take fat-soluble vitamins 2 hours before or after the Xenical intake.
Xenical is not recommended for some groups of patients including pregnant women, children, and patients with gallbladder impairment or chronic malabsorption syndrome. Patients with cholestasis and existing hypersensitivity to Xenical or to any component of the medication should not take the medication as well.
