title: Effects of selective serotonin reuptake inhibitors and venlafaxine during pregnancy in term and preterm neonates.
abstract: OBJECTIVE
  Our goals were to (a) describe neonatal behavioral signs in a group of newborns exposed in utero to selective serotonin reuptake inhibitors or venlafaxine at the time of delivery, (b) compare the rate of neonatal behavioral signs, prematurity, and admission to specialized neonatal care between a group of exposed and unexposed newborns, and (c) compare the effects in exposed preterm and term newborns.
  
  
  METHODS
  This was a retrospective cohort study including mothers taking selective serotonin reuptake inhibitors or venlafaxine during the third trimester and mothers who were not taking any antidepressants, psychotropic agents, or benzodiazepines at the time of delivery of their newborns. Neonatal behavioral signs included central nervous, respiratory, and digestive systems, as well as hypoglycemia and the need for phototherapy.
  
  
  RESULTS
  Seventy-six mothers taking antidepressants and 90 untreated mothers and their newborns were analyzed. Smoking, alcohol intake, and substance abuse were more frequent among treated mothers. In infants in the exposed group, signs involving the central nervous and the respiratory systems were often observed (63.2% and 40.8%, respectively). These signs appeared during the first day of life, with a median duration of 3 days for exposed newborns. The signs resolved in 75% of cases within 3 to 5 days for term and premature newborns, respectively. All exposed premature newborns presented behavioral manifestations compared with 69.1% of term exposed newborns. Median length of stay was almost 4 times longer for exposed premature newborns than for those who were unexposed (14.5 vs 3.7 days).
  
  
  CONCLUSIONS
  Neonatal behavioral signs were frequently found in exposed newborns, but symptoms were transient and self-limited. Premature infants could be more susceptible to the effects of selective serotonin reuptake inhibitors and venlafaxine.
