A review in JAMA Psychiatry, published on 1 October, draws together the evidence on depression and SSRI treatment in pregnancy. Major depression affects about 12% of pregnant patients, psychiatric illness is a leading cause of maternal morbidity and mortality, and maternal stress and depression themselves affect fetal and infant outcomes.
The authors argue that much of the observational literature on SSRI harms is confounded by the illness for which the drug is taken. Where studies have separated the two, the accumulated evidence suggests SSRIs carry little or no risk of serious adverse outcomes. Several studies describe harms when SSRIs are stopped in women with moderate to severe depression.
The practice change is in the default. Instead of stopping or withholding an SSRI when pregnancy is discovered, the review recommends a structured discussion of three things together: the risks of untreated or undertreated depression, the benefits of treatment, and the risks of SSRI exposure. For a woman who is well on an SSRI after moderate to severe depression, that discussion will usually favour continuing.
This is an expert narrative review rather than a new trial. It does not mean every pregnant woman with low mood needs medication; mild depression may be managed with psychological therapy. In India, where perinatal psychiatric services are limited outside large centres, the obstetrician or GP often makes this decision alone, which makes a clear default more useful.
- When a woman taking an SSRI becomes pregnant, do not stop it reflexively; review the severity of her past illness first.
- Discuss the risks of untreated depression alongside the risks of the medicine, and record the discussion.
- Ask about previous relapse when medicines were stopped — a strong reason to continue.
- Screen for depression at booking and again later in pregnancy and postpartum.
- Offer psychological therapy for mild depression; the case for medication is strongest in moderate to severe illness.
Why it matters
It reverses a common default, in which pregnancy is treated as a reason to stop rather than a reason to review.
Don't overread it
This is an expert review, not a new trial; small residual risks for some outcomes are not excluded.
