Pregnancy: The use of levocetirizine may be considered during pregnancy, if necessary.
Breast-feeding: Cetirizine, the race mate of levocetirizine, has been shown to be excreted in human. Therefore, the excretion of levocetirizine in human milk is likely. Adverse reactions associated with levocetirizine may be observed in breastfed infants. Therefore, caution should be exercised when prescribing levocetirizine to lactating women.
