Antipsychotic Use During Pregnancy Most Likely Safe
A new study suggests that women can continue using antipsychotic medications during the first trimester of pregnancy without meaningfully increasing the risk of birth defects in their offspring.
The study, by Krista F. Huybrechts and colleagues in the journal JAMA Psychiatry, looked at Medicaid users who filled at least one prescription for an antipsychotic medication during their first trimester of pregnancy, when an embryo’s vital organs are formed, and went on to have a live birth. Birth defects, including cardiac malformations, in these children were identified in the first 90 days after delivery and compared to the number of such abnormalities in the children of women on Medicaid who did not receive a prescription for an antipsychotic drug during the first trimester of pregnancy. The number of abnormalities was slightly higher in the children of women who had received atypical antipsychotics than in those who had not, and slightly lower in the children of women who had received a typical antipsychotic than in those who had not.
Huybrechts and colleagues concluded that taking an antipsychotic medication during the first trimester of pregnancy does not meaningfully increase the risk of birth defects in the offspring.
The children of women who took the antipsychotic risperidone did have a small increased risk of birth defects, including cardiac malformations. The researchers called for additional study of risperidone use during pregnancy.
