In brief: Yes

Alli is the over the counter & lower dose version of orlistat, a drug that blocks fat absorption from food.
Common minor side effects include:fatty/oily stools, increase defecation, fecal urgency/incontinence...The drug can also cause malabsorption of fat-soluble vitamins, thus a multivitamin is usually recommended to take with orlistat. Major side effects of orlistat include: liver/kidney toxicity.
