alli™ works by preventing the absorption of some of the fat you eat. The fat passes out of your body, so you may have bowel changes, known as treatment effects. You may get:
more frequent stools that may be hard to control
You may feel an urgent need to go to the bathroom. Until you have a sense of any treatment effects, it's probably a smart idea to wear dark pants, and bring a change of clothes with you to work
You may not usually get gassy, but it's a possibility when you take alli. The bathroom is really the best place to go when that happens
While no one likes experiencing treatment effects, they might help you think twice about eating questionable fat content. If you think of it like that, alli can act like a security guard for your late-night cravings
