Question

A woman with bipolar I disorder develops mania 3 weeks after giving birth. She is breastfeeding a healthy term infant and is not currently taking psychotropic medication. Following urgent specialist assessment, the team plans to start an antipsychotic. She wishes to continue breastfeeding. Which approach to medication and breastfeeding is most consistent with NICE CG192?

Accepted Answer

Discuss the limited safety data and drug-dependent milk levels, use the lowest-risk effective regimen, and monitor the infant for adverse effects.

Answer

Use a benzodiazepine alone because regular short-term sedation is the preferred definitive treatment for postnatal mania.

Answer

Replace the antipsychotic with lithium because therapeutic maternal serum concentrations predict negligible infant exposure.

Answer

Continue breastfeeding without infant monitoring because antipsychotic transfer into breast milk is clinically negligible.

Answer

Replace the antipsychotic with carbamazepine because NICE specifically recommends it when a mother wishes to breastfeed.
