Perinatal Outcome Following Third Trimester Exposure to Paroxetine
Bibliographic record
Abstract
BACKGROUND: Paroxetine hydrochloride is commonly used for maternal depression, panic disorder, and obsessive-compulsive disorder. The drug readily crosses the human placenta. Although it does not appear to increase teratogenic risk, there have been case reports of neonatal withdrawal. Symptoms were described soon after birth and lasted up to 1 month. OBJECTIVE: To investigate whether there is a clinically important discontinuation syndrome in neonates exposed to paroxetine in utero. METHODS: Prospective, controlled cohort study. PATIENTS: Fifty-five pregnant women counseled prospectively by the Motherisk program in Toronto, Ontario, regarding third-trimester exposure to paroxetine and their infants were included in the study group. Pregnant women who discontinued paroxetine before the third trimester or those receiving other drugs known to cause withdrawal-type symptoms, such as opioids or benzodiazepines, were excluded. A comparison group of 27 women using paroxetine during the first or second trimester and 27 women using nonteratogenic drugs were matched for maternal age, gravity, parity, social drug use, and nonteratogenic drug use. RESULTS: Of the 55 neonates exposed to paroxetine in late gestation, 12 had complications necessitating intensive treatment and prolonged hospitalization. The most prevalent clinical picture was respiratory distress (n = 9), followed by hypoglycemia (n = 2), and jaundice (n = 1). The symptoms disappeared within 1 to 2 weeks. In the comparison group, only 3 infants experienced complications (P =.03). In logistic regression, only third-trimester exposure to paroxetine was associated with neonatal distress (odds ratio, 9.53; 95% confidence interval, 1.14-79.3). CONCLUSION: When used near term, paroxetine is associated with a high rate of neonatal complications, possibly caused by its common discontinuation syndrome.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
