Alli (orlistat) is an over-the-counter drug meant for overweight adults who are struggling to shed excess pounds. 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. Orlistat is for use only in adults.

Generic Xenical is used for managing obesity in adults and adolescents 12 years and older. It is also used to reduce the risk of weight regain after previous weight loss.

Generic Neoral is used for preventing the rejection of organ transplants (kidney, liver, and heart). This medicine is also used to treat psoriasis and rheumatoid arthritis in certain patients.
