Pregnancy/Breast-Feeding
Implications |

There are no adequate and well-controlled studies of orlistat in pregnant
women. Because animal reproductive studies are not always predictive of human
response, orlistat is not recommended for use during pregnancy. Teratogenicity
studies were conducted in rats and rabbits at doses up to 800 mg/kg/day. Neither
study showed embryotoxicity or teratogenicity. This dose is 23 and 47 times the
daily human dose calculated on a body surface area basis for rats and rabbits,
respectively. It is not know if orlistat is secreted in human milk. Therefore,
it should not be taken by nursing women. |
|
|
Contraindications |
|
Chronic malabsorption syndrome or cholestasis; hypersensitivity to orlistat
or any component |
|
|
Warnings/Precautions |
|
Patients should be advised to adhere to dietary guidelines; gastrointestinal
adverse events may increase if taken with a diet high in fat (>30% total
daily calories from fat). The daily intake of fat should be distributed over
three main meals. If taken with any one meal very high in fat, the possibility
of gastrointestinal effects increases. Patients should be counseled to take a
multivitamin supplement that contains fat-soluble vitamins to ensure adequate
nutrition because orlistat has been shown to reduce the absorption of some
fat-soluble vitamins and beta-carotene. The supplement should be taken once
daily at least 2 hours before or after the administration of orlistat (ie,
bedtime). Some patients may develop increased levels of urinary oxalate
following treatment; caution should be exercised when prescribing it to patients
with a history of hyperoxaluria or calcium oxalate nephrolithiasis. As with any
weight-loss agent, the potential exists for misuse in appropriate patient
populations (eg, patients with anorexia nervosa or bulimia). Write/fill Rx
carefully. Dispensing errors have been made between
Xenical®(orlistat) and Xeloda™
(capecitabine). |

|
Single doses of 800 mg and multiple doses of up to 400 mg 3 times daily for
15 days have been studied in normal weight and obese patients without
significant adverse findings; in case of significant overdose, it is recommended
that the patient be observed for 24 hours |
