i would avoid it as much as possible; the fetal experiments they have conducted (on animals) are reported to show no abnormalities - but how can they conduct psychological tests on the fetuses? we're flat out doing psych evaluation on humans, let alone rabbit fetuses. sorry, i don't trust antidepressants, especially in pregnancy. another antidepressant contraindication is report of agitation of baby breastfed by mother using antidepressant.
maybe search lexapro/ fetal
