Use in pregnancy: In animal reproductive studies, no embryotoxic or teratogenic effects were observed with orlistat. In absence of teratogenic effect in animals, no malformative effect is expected in human beings. However, Xenical is not recommended for use during pregnancy in the absence of clinical data.
Use in lactation: The secretion of orlistat in human breast milk has not been investigated. Xenical should not be taken during breastfeeding.
