Orlistat is indicated for obesity management including weight loss and weight maintenance when used in conjunction with a reduced-calorie diet. Orlistat is also indicated for the reduction of the risk of weight regain after prior weight loss. Orlistat 120 mg is indicated for obese patients with an initial body mass index (BMI) ≥30 kg/m2 or ≥27 kg/m2 in the presence of other risk factors (eg, hypertension, diabetes, dyslipidemia) and Orlistat 60 mg is indicated for overweight & obese patients with an initial body mass index (BMI) ≥25 kg/m2.
Dosage:The recommended dose of Orlistat is one 60 mg or 120 mg capsule three times a day with each main meal containing fat (during or up to 1 hour after the meal). The patient should be on a nutritionally balanced, reduced-calorie diet that contains approximately 30% of calories from fat. The daily intake of fat, carbohydrate, and protein should be distributed over three main meals. If a meal is occasionally missed or contains no fat, the dose of Orlistat can be omitted.
Because Orlistat has been shown to reduce the absorption of some fat-soluble vitamins and beta-carotene, patients should be counseled to take a multivitamin containing fat-soluble vitamin to ensure adequate nutrition. The vitamin supplement should be taken at least 2 hours before or after the administration of Orlistat, such as at bedtime.
Side effects: Commonly-observed adverse events associated with the use of Orlistat include oily spotting, flatus with discharge, fecal urgency, fatty/oily stool, oily evacuation, increased defecation, fecal incontinence.
