·         You are allergic to orlistat.

·         You suffer from eating disorders, cholestasis (condition in which the flow of bile from the liver is blocked) or malabsorption syndrome (problems absorbing food or nutrients).

5.  Before You Start To Use This Medicine:

·         Inform your pharmacist or doctor if you have diabetes, kidney stones, pancreatitis (inflammation or swelling of the pancreas), gallbladder or thyroid disease, an organ transplantation, or any other health problems.

·         Inform your pharmacist or doctor if you are or plan to get pregnant, or are breastfeeding.
