  3. Postpartum Major Depression: 5-7% of post-partum women (within first 3 months of delivery)
  4. Postpartum Psychosis: 1-2 per thousand postpartum women

IV. Risk Factors

X. Management: Non-Medication

  1. Psychotherapy (esp. Cognitive Behavioral Therapy)
  2. Adjust social situation
    1. Longer maternity leave
    2. Return part-time

XI. Management: Standard Medications

  1. Approach
    1. Typically taper off Antidepressants after 6-12 months of depression remission (esp. if first depression episode)
  2. Women not Breast Feeding
    1. Selective Serotonin Reuptake Inhibitors (SSRI)
  3. Women who are Breast Feeding
    1. Safest agents in Lactation (undetectable in Breast Milk, L2 Risk)
      1. Sertraline (Zoloft) - preferred agent
      2. Paroxetine (Paxil)
        1. Safe in Lactation, but NOT in pregnancy
        2. Teratogenic if patient becomes pregnant again (therefore generally avoided)
    2. Agents with acceptably low levels in Breast Milk (L3 Risk)
      1. Escitalopram (Lexapro) - preferred agent
      2. Citalopram (Celexa)
      3. Venlafaxine (Effexor)
    3. Agents that are safe in Lactation, but excessive sedation or other side effects
      1. Nortriptyline
      2. Mirtazapine (Remeron)
      3. Fluvoxamine (Luvox)
    4. Agents to avoid in Lactation due to infant risks
      1. Fluoxetine (Prozac)
        1. Low levels in milk, but still more adverse effects in infants
        2. Teratogenic if patient becomes pregnant again (therefore generally avoided)
      2. Bupropion
        1. Risk of Seizures in newborns
  4. Avoid ineffective agents or those with insufficient evidence to support
    1. Avoid low dose Estrogen Replacement (also increases VTE Risk)
    2. Insufficient evidence for any supplement (e.g. St John's Wort, Folate, Vitamin D)

XII. Management: Medications for Refractory Postpartum Depression

  1. Zuranolone (Zurzuvae)
    1. Indicated in Postpartum Depression starting in third trimester or first month postpartum
    2. Like IV Brexanolone, mimics Allopregnanolone (GABA Receptor agent), known to decrease peripartum
    3. Schedule IV Controlled Substance
    4. Taken orally with a fatty meal in the evening for 14 days
      1. Started within 12 months of delivery, at a cost of $14,000/course
    5. Adverse effects include drowsiness and confusion
      1. Avoid driving for 12 hours after each dose
      2. Avoid with other CNS Depressants (e.g. Opioids, Alcohol)
    6. Drug Interactions include CYP3A4 Inducers (e.g. Phenytoin)
    7. Unknown safety in Lactation (may cause sedation in the nursing infant)
    8. Avoid in pregnancy (use Contraception)
    9. (2024) Presc Lett 31(2): 10-11
  2. Intravenous Brexanolone (Zulresso)
    1. Mimics Allopregnanolone (GABA Receptor agent) which normally decreases in peripartum period
    2. Intravenous infusion over 60 hours with onset of action by 24-48 hours
    3. Used in addition to standard SSRI agents
    4. Risk of sedation and loss of consciousness (REMS program)
      1. Monitor for excessive sedation and apnea (e.g. Pulse Oximetry)
    5. Schedule IV Controlled Substance
    6. Astronomically expensive ($34,000)
    7. Unknown safety in Lactation
    8. (2019) Presc Lett 26(5)

XIII. Complications

  1. Infant
    1. Failure to Thrive or Growth Faltering
    2. Attachment disorder
    3. Developmental Delay (at one year old)
  2. Mother
    1. Typical Major Depression symptoms (low energy, Insomnia, decreased concentration)
    2. Maternal Suicide
      1. Postpartum Suicide accounts for 20% of postpartum deaths
      2. Second only to Pulmonary Embolism as most common cause of postpartum death

    3. Traumatic delivery
  3. Counseling is effective and recommended by USPTF in the prevention of perinatal depression for those at risk
    1. See Risk Factors above
    2. Consider starting to screen for risk factors and Peripartum Depression in the second trimester of pregnancy
    3. See Evaluation Tools above for the diagnosis of perinatal depression
    4. Refer for Cognitive Behavioral Therapy (or interpersonal therapy) for those at risk
      1. Also see Resources above (e.g. Mothers and babies, ROSE Program)
  4. Other measures
    1. Single postpartum dose of Esketamine in those at risk for Postpartum Depression reduced risk
