  • Symptoms
  1. Depression lasts >2 weeks (contrast with Postpartum Blues)
  2. Comorbid anxiety and Agitation
  3. Most common symptoms
    1. Sadness is less commonly reported than in non-Postpartum Major Depression
    2. Guilt
    3. Worthlessness
    4. Anhedonia
    5. Decreased energy
    6. Difficulty sleeping when the baby is sleeping
  4. High risk symptoms (emergent mental health evaluation indications)
    1. Homicidal Thoughts
      1. Intrusive thoughts of hurting the newborn (may present as avoidance of the infant)
    2. Psychosis
      1. Hallucinations
      2. Delusions
      3. Rambling or pressured speech
    3. Suicidal thoughts
      1. Active Suicidal Ideation with a plan requires emergent psychiatric evaluation
      2. Passive Suicidal Ideation (e.g. no plan, but a wish go to sleep and not wake up) is more common
        1. Risk for progression to active Suicidal Ideation
  • Diagnosis
  1. See Major Depression Diagnosis
  2. Major Depression diagnosed during pregnancy or within 4 weeks postpartum
    1. Some experts recommend extending cut-off to one year after delivery
  • Differential Diagnosis
  1. Baby Blues
    1. Lasts <10 days (contrast with more than 2 weeks for depression)
    2. Onset within a few days of delivery
    3. Mild to no dysfunction (compared with moderate to severe dysfunction in depression)
  2. Bipolar Disorder
  3. Postpartum autoimmune Thyroiditis
  1. See Depression Screening Tools
  2. AAP recommends screening at perinatal visits and Well Child Visits (2, 4 and 6 months)

  • Management
  • Non-medication
  1. Psychotherapy (esp. Cognitive Behavioral Therapy)
  2. Adjust social situation
    1. Longer maternity leave
    2. Return part-time
  • Management
  • 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 (undetectable in Breast Milk)
      1. Sertraline (Zoloft) - preferred agent
      2. Paroxetine (Paxil)
        1. However, Teratogenic if patient becomes pregnant again (therefore generally avoided)
    2. Agents with acceptably low levels in Breast Milk
      1. Escitalopram (Lexapro) - preferred agent
      2. Citalopram (Celexa)
      3. Venlafaxine (Effexor)
    3. Agents that are safe, but excessive sedation or other side effects
      1. Nortriptyline
      2. Mirtazapine (Remeron)
      3. Fluvoxamine (Luvox)
    4. Agents to avoid 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. Refractory Postpartum Depression
    1. Intravenous Brexanolone
      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 agebts
      4. Risk of sedation and loss of consciousness (REMS program)
        1. Monitor for eccessive sedation and apnea (e.g. Pulse Oximetry)
      5. Astronomically expensive ($34,000)
      6. Unknown safety in Lactation
      7. (2019) Presc Lett 26(5)
  5. Avoid ineffective agents or those with insufficient evidence to support
    1. Avoid low dose Estrogen Replacement (also increases VTE Risk)
  • Complications
  1. Infant
    1. Failure to Thrive
    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
  • Prevention
  1. See Evaluation above for screening tools
    1. Perform at perinatal visits and Well Child Visits
  2. Consider home health visits, peer support for high risk mothers
    1. First-time mothers
    2. Teen mothers
    3. Traumatic delivery
