Importance: The association between maternal medications and the macronutrient composition of human milk has not been studied.
Objective: To compare macronutrient levels in milk samples from mothers treated with long-term medications with samples from untreated healthy and disease-matched control mothers (DMCs).
Design, Setting, And Participants: A cross-sectional study using samples collected between October 2014 and January 2024 from breastfeeding mothers in the US and Canada invited to participate to the Mommy's Milk Human Milk Research Biorepository at the University of California, San Diego.
Aim: We aimed to investigate plasma lamotrigine concentrations and clinical effects in infants exposed to lamotrigine through breastfeeding.
Methods: This was a retrospective study of mother-infant dyads in a clinical follow-up programme in Stockholm, Sweden. Data were collected from medical records.
Background: Neonatal effects of late intrauterine and early postpartum exposure to lithium through mother's own milk are scarcely studied. It is unclear whether described symptoms in breastfed neonates are caused by placental lithium transfer or postnatal exposure to lithium through breastfeeding. We aimed to investigate lithium clearance and neonatal morbidity in breastfed infants with high versus low serum lithium concentrations at birth.
