Patients who have experienced an episode of postpartum psychosis are predisposed to another episode in future pregnancies.1 Current research recommends prophylaxis of recurrence with lithium monotherapy.1,2,5,6 Similar to other psychotropics in reproductive psychiatry, maintenance therapy on lithium requires a thorough “risk vs risk” discussion with the patient. The risk of lithium use while pregnant and/or breastfeeding must be weighed against the risks associated with postpartum psychosis (ie, infanticide, suicide, poor peripartum care, or poor infant bonding).
OUTCOME Improved mood
After 7 days of inpatient treatment with quetiapine, Ms. A demonstrates improvement in the targeted depressive symptoms (including improved motivation/energy and insomnia, decreased feelings of guilt, and denial of ongoing suicidal ideation). Additionally, the thoughts of harming her baby are less frequent, and command auditory hallucinations resolve. Upon discharge, Ms. A and her partner meet with inpatient clinicians for continued counseling, safety planning, and plans for outpatient follow-up with the institution’s reproductive psychiatrist.
The authors’ observations
Many aspects of Ms. A’s initial presentation in the psychiatric ED were challenging. Given the presence of symptoms of both psychosis and OCD, a diagnosis was difficult to ascertain in the emergency setting. Since command auditory hallucinations are atypical in patients with postpartum OCD, the treatment team maintained high suspicion for postpartum psychosis, which represented an emergency requiring inpatient care.
Hospitalization separated Ms. A from her baby, for whom she was the primary caregiver. Additional considerations for inpatient admission and psychotropic initiation were necessary, because Ms. A was breastfeeding. Although Ms. A’s partner was able to provide full-time childcare, the patient ultimately did not agree to hospitalization and required an emergency hold for involuntary admission, which was an additional barrier to care. Furthermore, her partner held unfavorable beliefs regarding psychotropic medications and Ms. A’s need for hospital admission, which required ongoing patient and partner education in the emergency, inpatient, and outpatient settings. Moreover, if Ms. A’s symptoms were ultimately attributable to postpartum OCD, the patient’s involuntary hospitalization might have increased the risk of stigmatization of mental illness and treatment with psychotropics.
Bottom Line
The peripartum period is a vulnerable time for patients, particularly those with previously diagnosed psychiatric illnesses. Postpartum psychosis is the most severe form of postpartum psychiatric illness and often represents an episode of bipolar disorder. Due to an elevated acute risk of suicide and infanticide, postpartum psychosis is a psychiatric emergency and warrants inpatient hospitalization for immediate intervention.
