However, if women take prenatal vitamins with vitamin D and if vitamin K is given to the newborn, hemorrhagic disease rarely occurs.
Thus, women who have a seizure disorder should talk to an expert in the field about how to balance the risks of taking antiseizure medications with the risks of having seizures, preferably before they become pregnant. Some women may be able to safely stop taking antiseizure medications during pregnancy, but most women should continue to take the medications. The risk resulting from not taking the medications—more frequent seizures, which can harm the fetus and the woman—usually outweighs the risks resulting from taking antiseizure medications during pregnancy.
Doctors prescribe the lowest effective dose of the antiseizure medications and use as few different antiseizure medications as possible. Women who take antiseizure medications need to take a high dose of a folic acid supplement daily. Ideally, it is started before they become pregnant. Taking folic acid supplements helps reduce the risk of having a baby with a birth defect.
