A breastfeeding mother with postpartum OCD is being considered for an SSRI. Which agent has the most safety data supporting use during lactation?
Answer: Sertraline
Sertraline has extensive lactation safety data, showing low breast milk transfer and minimal infant serum levels.
Which benzodiazepine characteristic is most relevant when prescribing to a breastfeeding mother who needs short-term anxiolytic coverage?
Answer: Half-life and active metabolites
Shorter half-life agents with fewer active metabolites (e.g., lorazepam) reduce infant accumulation during breastfeeding.
A patient at 10 weeks gestation has bipolar I disorder and is stable on lithium. What is the primary fetal risk that must be weighed in the decision to continue?
Answer: Ebstein's anomaly
Lithium is associated with Ebstein's anomaly (tricuspid valve malformation), though absolute risk is low (~1 in 1000 exposed).
Which antidepressant is generally avoided in breastfeeding due to the highest relative infant dose (RID) and long half-life?
Answer: Fluoxetine
Fluoxetine has the longest half-life and an active metabolite (norfluoxetine), resulting in the highest RID among SSRIs.
A patient taking valproate who becomes pregnant is at highest risk for which fetal outcome?
Answer: Neural tube defects and cognitive impairment
Valproate carries the highest teratogenic risk among mood stabilizers, causing neural tube defects and significant neurocognitive impairment in exposed children.
A postpartum patient with severe depression requires augmentation. Which atypical antipsychotic has the most favorable lactation profile due to low milk transfer?
Answer: Quetiapine
Quetiapine has low relative infant dose (<1%) and is generally preferred when an atypical antipsychotic is needed during breastfeeding.
When discontinuing an SSRI during pregnancy to minimize neonatal adaptation syndrome, what is the recommended timing?
Answer: Discontinue at 36 weeks gestation
Tapering SSRIs around 36 weeks may reduce neonatal adaptation syndrome while balancing the mother's relapse risk in late pregnancy and postpartum.
