Knowns and Unknowns About SSRI Use During Pregnancy in 2022

The last 15-20 years have brought enormous attention to the relevant clinical issues regarding prescribing antidepressants during pregnancy. Concern about the effects of fetal exposure to selective serotonin reuptake inhibitors (SSRIs) is appropriate given the consistent data that approximately 7% of women use antidepressants during pregnancy, and that risk for relapse of depression during pregnancy in women who have stopped antidepressants during pregnancy is very high.

We have learned so much from studies of relevant questions regarding SSRI exposure. Concerns about increased risk for organ malformation have been set aside. An extraordinary number of studies across a broad range of patients around the globe looked at the issue of risk for organ malformation following in utero SSRI exposure — even looking specifically at risk for cardiac malformations, which had been an earlier concern in the literature — with the evidence supporting absence of increased risk.

Also clarified has been, first, the absence of risk of complications such as persistent pulmonary hypertension of the newborn (PPHN) and, second, a delineation of the prevalence and clinical implications of transient neonatal symptoms such as jitteriness and tachypnea in offspring of women who used antidepressants during pregnancy — so-called "poor neonatal adaptation syndrome."

However, for so many clinicians and for patients, the missing piece in the risk-benefit equation has been the issue of long-term neurodevelopmental sequelae in children whose mothers used antidepressants during pregnancy.
