Managing Medications in Pregnancy

Medication Adjustment and Monitoring

  • The American College of Obstetricians and Gynecologists recommends continuing SSRIs at the lowest effective dose rather than discontinuing, as risks of untreated maternal depression outweigh small fetal risks 1
  • Escitalopram or sertraline are preferred first-line options as they have the most extensive pregnancy safety data among SSRIs 1
  • Multiple reviews have not identified adverse neurodevelopmental outcomes among infants born to women treated with SSRIs during pregnancy 1
  • Monitor closely for 2-4 weeks after switching from desvenlafaxine to an SSRI for symptom recurrence or worsening 2
  • The American Journal of Obstetrics and Gynecology suggests that if ADHD symptoms become severely impairing, consider intermittent methylphenidate use or bupropion as an alternative 2

Lamotrigine Management

  • Lamotrigine can be safely continued during pregnancy with appropriate monitoring 3
  • Lamotrigine levels decrease significantly during pregnancy due to increased metabolism and clearance, and should be checked monthly during pregnancy 3
  • Many women require dose increases of 50-100% or more during pregnancy to maintain stability, and the dose should be rapidly reduced postpartum to avoid toxicity 3
  • Obtain baseline lamotrigine level in the first trimester, and recheck levels every 4 weeks to adjust the dose and maintain pre-pregnancy therapeutic level 3
