Overview
Orlistat, marketed as Xenical (prescription) and Alli (over-the-counter), is a gastrointestinal lipase inhibitor that blocks dietary fat absorption. It was approved in 1999 as the first long-term weight management drug available without central nervous system stimulation.
Uses
Indicated for obesity management in adults and adolescents, used with a reduced-calorie, low-fat diet. It also helps prevent weight regain after initial loss and improves obesity-related risk factors such as type 2 diabetes, hypertension, and dyslipidemia.Dosage & Administration
Prescription dose: 120 mg three times daily during or up to 1 hour after each main meal containing fat. Skip the dose if the meal is fat-free. Multivitamin supplements are advised at bedtime to replace fat-soluble vitamins (A, D, E, K) lost during therapy.Side Effects & Warnings
Most common: gastrointestinal—oily stools, flatulence, and urgency—due to unabsorbed fat. These effects lessen with reduced fat intake. Rare: liver injury and oxalate kidney stones. Contraindicated in chronic malabsorption or cholestasis.Patient Considerations
Adherence to a low-fat diet is essential for tolerability and success. Maintain hydration and regular vitamin supplementation.Ready for next steps?
