With any pregnancy there is a small chance that your baby may not develop normally in the womb. The risk of this happening may be slightly higher with anti-epileptic drugs. The risk of harm to your baby is higher with sodium valproate than others. The most common problems for your baby linked to these medications include spina bifida, facial cleft or heart abnormalities. If you are planning a pregnancy it is important to discuss this with your GP or epilepsy specialist. This is because they may wish to change your medications or dose for use in pregnancy.
