Narrative synthesis of observational literature
Trazodone Use in Pregnancy: A Review of Observational Data
A closer look at what the observational research base — cohort studies, case series, and case reports — says (and doesn't say) about trazodone safety in pregnancy.

Who was studied: Pregnant women who used trazodone, across published cohort studies, case series, and case reports spanning several decades
Because randomized trials in pregnancy are not conducted for ethical reasons, what we know about most medications' safety in pregnancy — trazodone included — comes from observational sources: cohort studies that track outcomes in women who happened to take the medication, case series, and individual case reports compiled over time.
For trazodone, current FDA labeling describes this observational base, spanning several decades, as not having identified a clear pattern of major birth defects or adverse maternal/fetal outcomes associated with the drug specifically. This is reassuring, though it's paired with an honest acknowledgment that the overall dataset is smaller than exists for some other, more extensively studied antidepressants — which is exactly why individualized decision-making with a prescriber and OB team remains the standard recommendation rather than a blanket answer.
Main result: Per current FDA labeling, published prospective cohort studies, case series, and case reports spanning several decades of trazodone use in pregnant women have not identified a clear pattern of drug-associated major birth defects, miscarriage, or adverse maternal/fetal outcomes — while acknowledging the overall human data set remains smaller than for some more extensively studied antidepressants.
Limitations: Observational studies, even when reassuring, generally cannot rule out risk as definitively as they could confirm one — absence of a clear signal in available data is meaningfully reassuring but not equivalent to a large, dedicated safety trial, which would not be ethical to conduct in pregnancy in the first place.
