Long-acting injectable (LAI) antipsychotics have been widely used to improve adherence and prevent relapse in patients with various severe psychotic disorders, but there is a lack of high-quality data from previous research on the safety of LAI antipsychotics during pregnancy.
Considering that previous reviews on this topic included only selected cases published before January and March 2021, respectively, and that several case reports/series reporting outcomes of pregnancy in women using LAI antipsychotics were published in the meantime or were published earlier but not included in previous reviews, there is a need for an updated review.
We aimed to provide an up-to-date summary of the relevant data on maternal, pregnancy, neonatal, and developmental outcomes from available published cases of LAI antipsychotic use in pregnancy.
A literature search was performed through November 11, 2023, using three online databases: PubMed/MEDLINE, Scopus, and Web of Science. Case reports or case series that reported information about the outcomes of pregnancy in women who used LAI antipsychotics at any point in pregnancy, with available full texts, were included. Descriptive statistics, narrative summation, and tabulation of the extracted data were performed.
A total of 19 publications satisfied the inclusion criteria: 3 case series, 15 case reports, and 1 conference abstract. They reported the outcomes of LAI antipsychotic use in 74 women and 77 pregnancies. Most of the women (approximately 64%) had either satisfactory control of symptoms or no information about relapse. A minority of cases reported adverse outcomes such as stillbirth, spontaneous abortion, preterm birth, low birth weight, congenital anomalies, and neurological manifestations in newborns. However, there were no reports of negative long-term developmental outcomes.
Currently available data seem reassuring, given that most of the women seemed to have satisfactory control of the symptoms and that a minority of the cases reported adverse outcomes.
Considering that the currently available research consists only of case reports and series, additional well-designed studies are needed to properly evaluate the risks and benefits of LAI antipsychotic use during pregnancy.
