Is carbatrol safe for women who are pregnant or breastfeeding?

Category D / L2. In pregnancy this drug has some fetal risk & should only be used if an alternative is not available with less risk. After delivery, the med is considered relatively safe for breastfeeding.
Yes. This is usually used for seizures. There are associated birth defects with it. However, not taking the drug and risking a seizure while pregnant is also problematic for mother and baby. If you need to be on this medication then you should take extra Folic Acid and will need some extra vitamin k during the last month of the pregnancy. It is ok with breastfeeding.
