According to AP, some 27 percent of Xenical users had at least one episode, although the side effects tend to wane the longer people take the drug. Experts warn Xenical is supposed to be only for clinically obese people on strict diets. We don't want it used just casually by itself without any diet, or just for cosmetic weight loss. Xenical is the first-ever diet drug that works in the gut instead of targeting the brain to suppress appetite, said the news wire. In studies, adding Xenical to a diet let people lose about 7 pounds more in a year than diet alone, the Food and Drug Administration found.
Dieters take one Xenical capsule with each main meal, up to three daily.
