Information on neurodevelopmental effects of antenatal exposure to antipsychotics is limited to 10 studies, all examining children up to 5 years of age or less. The paper aimed to investigate the association between in utero exposure to antipsychotics and psychiatric outcomes in children using Danish nationwide registers. In total, 9011 liveborn singletons born 1998–2015 in Denmark whose mothers took antipsychotic medication before pregnancy were identified. Children whose mothers continued to take antipsychotics during pregnancy were compared with children of mothers who discontinued antipsychotics before pregnancy. As a negative control, paternal antipsychotic use in the same window was investigated. Hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated using Cox proportional hazards regression for the primary outcome of psychiatric disorders, as well for subcategories of psychiatric disorders. In total, 9.9% of children in the discontinuation group and 11.0% of children in the continuation group received a psychiatric disorder diagnosis during follow-up. The adjusted HR for psychiatric disorders among offspring in the continuation group compared to the discontinuation group was 1.10 (95% CI 0.93–1.30). For antipsychotic use in the fathers, the HR was 1.05 (95% CI 0.89–1.24). The study does not provide evidence of increased risk of psychiatric disorders among children of women who continue antipsychotic treatment during pregnancy. This was observed after accounting for the underlying risk conferred by maternal psychiatric disorders. This suggests women who need to continue antipsychotic medications during pregnancy can do so without adverse psychiatric outcomes for offspring.
