Understanding Anti-Seizure Medications (ASMs) & Child Outcomes
Studies on children born to a parent taking ASMs during pregnancy have shown that for many ASMs, there was little or no difference in the development of babies compared to those born to people who did not take ASMs. The risks of taking certain ASMs during pregnancy are relatively low when compared with other types of medicines or exposure to other substances like thalidomide or alcohol.
ASMs & Pregnancy
To improve your chances for a healthy pregnancy and a healthy baby, ideally you should start planning any adjustments to your ASMs as much as 12 months before trying to become pregnant.
