What is Orlistat and what it is used for?
Orlistat blocks some of the fat that you eat, keeping it from being absorbed by your body. Orlistat is used to aid in weight loss, or to help reduce the risk of regaining weight already lost. This medicine must be used together with a reduced-calorie diet and increased physical activity. Orlistat is for use only in adults that are overweight or obese.
