Getting plenty of sleep and taking your medication as directed will also reduce the risk. Some of the common factors which can increase seizures during pregnancy is lack of sleep, failure to take medication, poor control prior to pregnancy and changes in the metabolism of medication caused by pregnancy. Getting adequate sleep can not be any more important then now. Your system is already working overtime and lack of sleep is a well known trigger. Try to identify other triggers for your seizures and try to avoid them if possible.
Pregnancy changes the body's level of medication.
The level becomes lowest right before delivery. Have your blood levels checked on a regular basis to see if adjustments in medication is needed. It will also help to keep a record of your seizures. This will help your physician evaluate what should be changed or kept the same. Many women consider going off of thier medications while pregnant to reduce the risk of birth defects.
