The first ever FDA approved, over the counter diet pill hits store shelves Friday. It's called Alli and it's basically a smaller dose of the diet aid Xenical.
Its main ingredient is Orlistat, which is a fat blocker that will block an estimated 25 percent of the fat you eat.
The drug is taken three times a day with meals and should be combined with an exercise and diet plan.
The number one side effect, as described by its makers, is bowel changes such as having an urgent need to use the bathroom.
Alli is for sale beginning Friday, June 15. A one month supply should cost about $60.
