Lamotrigine
Lamotrigine (Lamictal) transfers into breast milk in relatively high amounts — infant blood levels can reach 30–50% of maternal levels. Despite this, most breastfed infants tolerate it well with no significant adverse effects in published studies. Breastfeeding is generally considered acceptable, but monitor your baby for sedation, poor feeding, or rash, and have your pediatrician check infant blood levels if concerned.
Lamotrigine has one of the highest milk-to-plasma ratios among anticonvulsants, and infant serum levels can be substantial. However, multiple studies of breastfed infants exposed to lamotrigine have not found significant adverse effects. The benefits of breastfeeding generally outweigh the risks. Importantly, lamotrigine is metabolized faster during pregnancy, so postpartum dose adjustments may be needed (doses often need to be reduced after delivery). Work closely with your neurologist or psychiatrist.
Always confirm with your doctor or lactation consultant before making dietary changes while breastfeeding.
