Alli can safely be used for up to 2 years, as this was the duration of the clinical studies. Do note the majority of the weight in any program is lost in the first six months and then it slows down, but with motivation and hard work you can achieve your goal. One year is a reasonable time frame.
It is recommended to ask your physician prior to taking alli , when you have had a history of gallbladder disease. Some people have a problem with digesting food, especially fat without a gallbladder.
