The use by mothers of any of four major classes of psychiatric medications during pregnancy significantly raises the risk that their babies will be born with low birth weights and will need to be hospitalized, according to a study in the Journal of Clinical Psychiatry.
The team of French researchers examined records and conducted interviews with 1,071 mothers in France, and found that nearly half (40.2%) had used at least 1 psychotropic drug during pregnancy. Adjusting for other confounding factors, they found that taking mood stabilizers doubled the risk of having a child with low birth weight, and taking an antipsychotic, an antidepressant or an anxiolytic/hypnotic raised the risk of neonatal hospitalization by a factor of 1.74, 1.59 and 1.89 respectively.
“Infants exposed to psychotropic drugs during pregnancy have less optimal neonatal outcome than unexposed infants and should be considered as a high-risk population,” the researchers concluded.
