Alli is a weight loss drug launched by GlaxoSmithKline.  This latest weapon in the battle of the bulge should find willing takers in the market. Alli has shown positive results during clinical trials in which subjects showed up to seven percent loss in body weight when they underwent a program that involved diet, exercise and Alli.

Yet, as with every drug there are side effects to Alli, these include gas, frequent bowel movements and loss of control of bowel function. The side effects are a result of the drug’s action which blocks the absorption of fat in the intestine; the fat is then eliminated in the stool. The FDA however does not seem to have a problem with the drug.
