Hi dear, Lamictal contains lamotrigine. This drug is secreted in breastmilk, and can cause adverse effects like skin rash, drowsiness and poor feeding in baby. The effect depends, to some extent, on the dose you are taking. So kindly discuss with your psychiatrist and pediatrician beforehand, so that we can do dose adjustments as necessary(may be able to decrease dose after delivery) and close monitoring for any effect on baby Hope I have answered your query Let me know if I can assist you further Dr Muhammed Aslam, Paediatrician
