Aripiprazole, brexpiprazole, and cariprazine can affect milk supply: Advice to breastfeeding mothers.

OBJECTIVE: We sought to review the effects of Dopamine Receptor Partial Agonist (DRPA) antipsychotic medications on milk supply and breastfeeding. METHOD: Narrative review of selected literature including animal and human data. RESULTS: Scant case study evidence suggests that DRPAs may lead to reduced milk supply for some. CONCLUSIONS: Women taking DRPAs should be advised of the possibility that these may affect milk supply, and reporting should be encouraged to aid future research.
