Viguera AC, Vanderkruik R, Gaccione P, et al. - Researchers conducted the study for analyzing initiation rates of breastfeeding and other breastfeeding outcomes among women taking second-generation antipsychotics (SGAs). Participants were recruited in the National Pregnancy Registry for Atypical Antipsychotics, an ongoing prospective cohort study of women aged 18–45 years who have been exposed or have not been exposed to SGAs during pregnancy. A 3-month postpartum interview is used to gather information about breastfeeding behaviors. Participants who did not use SGAs had higher rates of breastfeeding initiation and continuation. Women who were not on SGAs reported “ever breastfeeding” at a rate of 88.2%, compared with 59.3% of women who were on an SGA. At 3 months postpartum, 47% of non-SGA women were exclusively breastfeeding, compared to 23% of SGA women. Despite the fact that the majority of women on an SGA started breastfeeding, breastfeeding rates were significantly lower than for women who were not on an SGA.
