Xenical blocks some of the fat that you eat, keeping it from being absorbed by your body.
Xenical is used to aid in weight loss, or to help reduce the risk of regaining weight already lost. This medicine must be used together with a reduced-calorie diet and is to used only by adults.
Before taking this medicine
You should not use Xenical if you are allergic to orlistat, or if you have malabsorption syndrome (an inability to absorb food and nutrients properly).
You also should not use this medicine if you have:
- gallbladder problems; or
- if you are pregnant.
Do not use alli if:
- you are not overweight;
- you have had an organ transplant; or
- you use cyclosporine (to prevent organ transplant rejection).
To make sure Xenical is safe for you, tell your doctor if you have ever had:
- kidney stones;
- gallbladder disease;
- underactive thyroid;
- liver disease;
- kidney disease; or
- an eating disorder (anorexia or bulimia).
Do not use Xenical if you are pregnant. Weight loss is not recommended during pregnancy, even if you are overweight. Stop taking orlistat and tell your doctor right away if you become pregnant.
Taking orlistat can make it harder for your body to absorb certain vitamins. These vitamins are important if you are nursing a baby. Do not use this medicine without a doctor’s advice if you are breast-feeding a baby.
Xenical is not approved for use by anyone younger than 12 years old. Do not give alli to anyone under 18 years old.
