This is an iatroX educational summary of named Canada sources, not an official guideline. It does not replace the complete source documents, local policy, specialist advice or clinical judgement. The evidence source is pan-Canadian, but formularies, funded access, referral routes, public-health directions and service availability remain provincial or territorial.

Source and scope

This summary is bounded to the recommendations, population and decisions covered by Guideline No. 454: Identification and Treatment of Perinatal Mood and Anxiety Disorders. Apply it with the current provincial or territorial pathway where implementation differs.

Source-attributed clinical priorities

  • Screen and assess depression, anxiety, bipolar disorder, psychosis, substance use, trauma, suicide risk and infant safety during pregnancy and postpartum.
  • Balance untreated-illness risk with medication and therapy evidence through shared decisions rather than stopping effective treatment abruptly.
  • Treat postpartum psychosis, mania or imminent safety risk as an emergency and coordinate obstetric, psychiatric and infant care.
  • Screen for bipolar history before treating perinatal depression because postpartum mania risk changes the plan.

Practical assessment and management workflow

1
Assess mood, anxiety, sleep beyond infant care, intrusive thoughts, psychosis, trauma, substances and supports.
2
Clarify suicide, infant-harm thoughts, intent, insight and ability to provide safe care.
3
Balance illness relapse against fetal, neonatal and breastfeeding medicine considerations with shared decisions.
4
Arrange proactive pregnancy and postpartum follow-up involving obstetric, primary and mental-health teams.

Safety, red flags and urgent escalation

  • Postpartum psychosis, mania, severe depression or intent to harm self or infant is an emergency.
  • Do not stop a stable psychotropic abruptly solely because of pregnancy.
  • Distinguish unwanted ego-dystonic intrusive thoughts from psychotic beliefs while taking all safety concerns seriously.
