Some people may wonder if they can buy orlistat (
Alli™,
Xenical®) without a prescription. This medication is available with or without a prescription. Alli is the non-prescription form of orlistat, while Xenical is the prescription version.
Both versions work by decreasing the absorption of fat from your diet. The stomach and intestine have enzymes, called lipases, that break down fat into smaller molecules, which are then absorbed from your digestive tract. Orlistat binds to lipases and inhibits their activity, helping to decrease fat absorption.
Whether using orlistat without a prescription or with a prescription, the dosage is the same, regardless of age, weight, or other medical conditions. This medicine is taken by mouth with each fat-containing meal, up to three times per day.
