Alli (Orlistat) Drug Information
In order to help ensure safe use, drug information on Alli™ (orlistat) should be thoroughly reviewed before you begin using the diet pill.
Alli is approved for adults with a body mass index (BMI) of 27 or greater (see BMI Calculator to find your BMI). It is important that you combine Alli with a reduced-calorie, low-fat diet. Eating too much fat increases the risk of side effects, such as abdominal pain, oily spotting (uncontrolled anal seepage of oil), gas, and the urgent need to have a bowel movement. In general, you should try to limit your fat intake to less than 30 percent of your total daily calories.
On average, Alli tends to prevent the absorption of approximately 25 percent of the fat in the diet. Studies have shown that when used in combination with dieting, this medication helps people lose 50 percent more weight than with just dieting alone. The exact amount of weight loss people experience while taking the drug depends on several factors, including their diet and exercise habits. It is reasonable to expect a modest and gradual weight loss with Alli combined with dieting -- about one to two pounds per week.
