A JAMA Psychiatry narrative review by perinatal psychiatrists and pharmacoepidemiologists assessed what is known about depression and SSRI treatment in pregnancy. In the US, 5% to 6% of pregnant women take an SSRI, and major depression affects about 12% of pregnancies. Psychiatric illness is among the leading causes of maternal morbidity and mortality.
The review's central point is about confounding. Many early observational studies attributed to SSRIs outcomes that partly reflect the depression they were treating. When studies separate the drug from the illness, the authors judge that SSRIs carry little or no risk of serious adverse outcomes. Several studies, by contrast, describe harm when women with moderate to severe depression stop treatment.
The authors call for a structured shared decision: weighing the risks of untreated or undertreated illness against the benefits of treatment and the known risks of SSRI exposure, rather than defaulting to stopping the drug when pregnancy is found.
In practice, the common reflex of stopping an SSRI at a positive pregnancy test is the decision most worth revisiting. This is a review, not new trial data, and it does not alter any guideline on its own.
- Do not stop an SSRI automatically when pregnancy is confirmed; review severity and history first.
- In moderate to severe or recurrent depression, discuss the documented risks of stopping treatment.
- Use a structured conversation covering untreated illness, treatment benefit and drug exposure.
- Coordinate with the obstetric team so the woman hears a consistent message.
- Screen for depression at booking and again later in pregnancy and after birth.
Why it matters
The reflex to stop antidepressants at conception may be causing more harm to mothers and infants than the drugs themselves.
Don't overread it
This is an expert narrative review rather than new data, and it does not mean every pregnant woman with mild symptoms needs an SSRI.
