Pregnancy: Although there are no adequate and controlled studies to date in humans, Hydroxyzine has been shown to be teratogenic in mice, rats, and rabbits when given at dosages substantially greater than the therapeutic human dosage. Pending accumulation of further data regarding safety in pregnant women, Hydroxyzine is contraindicated during early pregnancy.
Breast-feeding: It is unknown whether Hydroxyzine is excreted in human milk. Hydroxyzine should not be used in women who are breastfeeding.
