Safety of Sertraline During Pregnancy

Benefits vs. Risks Assessment

  • Depression during pregnancy is associated with premature birth and decreased initiation of breastfeeding, making treatment important for maternal and fetal wellbeing 1, 2
  • Sertraline is one of the most commonly prescribed antidepressants during pregnancy and breastfeeding due to its favorable safety profile 2

Potential Risks

  • Some studies suggest a possible association between SSRI use during pregnancy and persistent pulmonary hypertension of the newborn (PPHN), though evidence is conflicting 1, 2
  • A meta-analysis indicated a number needed to harm of 286-351 for PPHN with late pregnancy SSRI exposure 1, 2
  • A large population-based cohort study found no link between first-trimester antidepressant use and cardiac malformations 1, 2

Management Recommendations

  • Use the lowest effective dose of sertraline during pregnancy 3
  • Monitor for symptoms of depression throughout pregnancy, as untreated depression poses significant risks 1, 2
  • For women already taking sertraline who become pregnant, continuation of treatment is generally recommended if clinically indicated 3
  • Arrange for early follow-up after hospital discharge for infants exposed to sertraline in the third trimester to monitor for neonatal adaptation syndrome 3

Breastfeeding Considerations

  • Sertraline transfers in low concentrations into breast milk and is considered one of the preferred antidepressants during breastfeeding 1, 2
  • Paroxetine and sertraline are the most commonly prescribed antidepressants during breastfeeding due to their favorable safety profiles 1, 2

Clinical Decision Algorithm

  • Assess severity of depression and necessity of medication treatment 3
  • If treatment is indicated, sertraline is a preferred option during pregnancy 1, 2
  • Use the lowest effective dose and monitor maternal mental health closely 3
  • Continue sertraline during breastfeeding if clinically indicated 1, 2
