Epilepsy is a condition in which patients have seizures. Medications, known as antiepileptic drugs (AEDs), are often used to prevent seizures. These medications include carbamazepine, lamotrigine, phenytoin, or valproate. Mothers who take AEDs are often warned against taking these medications during pregnancy because of known risks to the baby during pregnancy. Mothers who are taking AEDs may have concerns about breastfeeding while taking these medications. In the past, concerns have included risks to the child’s brain development and intelligence potential. A research study in this month’s JAMA Pediatrics included mothers who were taking AEDs while breastfeeding. The research team studied their children’s health up to age 6 years. This research study found no negative effects on the children’s health or brain development from breastfeeding by mothers who were taking these drugs. If you are a new mother taking AEDs, this study provides support that it is safe to breastfeed your baby.
