What is orlistat?

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.

It is dangerous to purchase orlistat on the Internet or from vendors outside of the United States. Medications distributed from Internet sales may contain dangerous ingredients, or may not be distributed by a licensed pharmacy. Samples of "alli" purchased on the Internet have been found to contain sibutramine (Meridia), a prescription weight loss medication that can have dangerous side effects in certain people. For more information, contact the U.S. Food and Drug Administration (FDA) or visit www.fda.gov/buyonlineguide.
