 My doctor told me I could take it indefinitely. He said it would not hurt. 

 Hello. You can safely use alli until you reach your goal weight. Orlistat, the active ingredient in alli has been widely studied for safety - for up to 4 years in some studies. Congratulations on your success so far- I am happy to hear you are doing well on the alli plan.

Hope this helps! Keep up the good work!
