Over-the-counter approval was controversial in the United States, with consumer advocacy group Public Citizen repeatedly opposing it on safety and efficacy grounds. Generic formulations of orlistat are available in some countries. In Australia it has been listed as an S3 medication, available from a pharmacist without a prescription, since 2000. Medical uses
Orlistat is used for the treatment of obesity. The amount of weight loss achieved with orlistat varies. In one-year clinical trials, between 35.5% and 54.8% of subjects achieved a 5% or greater decrease in body mass, although not all of this mass was necessarily fat. Between 16.4% and 24.8% achieved at least a 10% decrease in body fat. After orlistat was stopped, a significant number of subjects regained weight—up to 35% of the weight they had lost. It reduces the incidence of diabetes type II in people who are obese around the same amount that lifestyle changes do. Long-term use of orlistat also leads to a very modest reduction in blood pressure (mean reductions of 2.5 and 1.9 mmHg in systolic and diastolic blood pressure respectively). Contraindications
Orlistat is contraindicated in:
Malabsorption
Hypersensitivity to orlistat
Reduced gallbladder function (e.g. after cholecystectomy)
Pregnancy and breastfeeding
Anorexia and Bulimia
Use caution with: obstructed bile duct, impaired liver function, and pancreatic disease

Side effects
The primary side effects of the drug are gastrointestinal-related, and include steatorrhea (oily, loose stools with excessive flatus due to unabsorbed fats reaching the large intestine), fecal incontinence and frequent or urgent bowel movements.
