Question 1

A perinatal patient with ADHD asks about stimulant medication safety during breastfeeding. What is the most accurate statement?

Accepted Answer

Data are limited; amphetamines concentrate in breast milk and infant exposure warrants careful consideration

Answer

Amphetamine-based stimulants concentrate in breast milk with milk-to-plasma ratios >1, so use during breastfeeding requires individualized risk-benefit discussion.

Question 2

Which physiological change in pregnancy most significantly affects the volume of distribution of psychotropic medications?

Accepted Answer

Expanded plasma volume and increased body fat

Answer

Pregnancy-related plasma volume expansion (~50%) and increased body fat increase the volume of distribution of lipophilic psychotropics, often lowering effective serum levels.

Question 3

A patient is prescribed an SNRI for perinatal depression. Which additional counseling point differentiates SNRIs from SSRIs in the perinatal context?

Accepted Answer

SNRIs have norepinephrine effects that may contribute to hypertension and should be monitored in preeclamptic patients

Answer

SNRIs' noradrenergic activity can elevate blood pressure, which is especially relevant in patients at risk for or diagnosed with preeclampsia.

Question 4

A patient stabilized on aripiprazole for bipolar disorder plans to breastfeed. What is the most clinically relevant concern with this medication during lactation?

Accepted Answer

Aripiprazole has been shown to suppress prolactin and may inhibit milk production

Answer

Aripiprazole's partial dopamine agonism can suppress prolactin, potentially reducing milk supply in breastfeeding mothers.

Question 5

What is the primary rationale for preferring lamotrigine over valproate in a woman of reproductive age with bipolar II disorder?

Accepted Answer

Valproate carries a significantly higher teratogenic risk and is associated with fetal cognitive impairment

Answer

Valproate's well-documented teratogenicity (neural tube defects, cognitive impairment) makes lamotrigine the preferred mood stabilizer for women who may become pregnant.
