Does Xenical Work?
Xenical® (orlistat) is a prescription medicine commonly used as a weight loss aid for people with a body mass index (BMI) of 30 or greater. Many people may wonder, "Does it work?" The answer is yes -- Xenical has been shown in clinical studies to help people lose weight.
After six months of taking the drug while dieting, people lost an average of 12.4 pounds (compared to just 6.2 pounds for people who were just dieting). After a year, those taking it while dieting had lost a total of 13.4 pounds, on average (compared to 5.8 pounds for those just dieting).
In studies of Xenical in people with type 2 diabetes, the drug improved several measures of diabetes control, such as fasting glucose and hemoglobin A1c, and many people were able to reduce or discontinue their diabetes medications. Studies have also shown that the drug can help prevent type 2 diabetes in people with obesity.
Xenical has also been studied as an aid to help people who have already lost weight keep the weight off. In one study, 52 percent of people not taking it regained the weight they had lost, compared to just 26 percent of people who took the drug.
