Page 4 of 9 Pregnancy, contraception in women, and breast-feeding Pregnancy Epanutin can cause major birth defects. Taking phenytoin during pregnancy increases the chance that the baby may have physical birth abnormality. Studies with women treated with phenytoin for epilepsy during pregnancy have shown that around 6 babies in every 100 will have serious physical birth abnormalities. This compares to 2-3 babies in every 100 born to women who don’t have epilepsy. The most common types of serious physical birth abnormalities (major congenital malformations) report for phenytoin include abnormalities of the lip and palate, heart, skull, nail and finger disorders and growth abnormalities. Some of these may occur together as part of a fetal hydantoin syndrome. Your unborn baby should be closely monitored if you have taken Epanutin while pregnant. Epanutin should not be used during pregnancy unless nothing else works for you. Taking more than one epilepsy medicine at the same time may also increase the risk of physical birth abnormalities. Where possible, your doctor will consider using one epilepsy medicine only to control your epilepsy. Your doctor may advise you to take folic acid if you’re planning to become pregnant and while you’re pregnant. Your doctor may adjust your epilepsy medicine when you take folic acid. Some studies observed that taking phenytoin during pregnancy increases the chance that the baby may have problems affecting learning and thinking abilities. Problems with neurodevelopment (development of the brain) have been reported in babies born to mothers who used phenytoin during pregnancy. Some studies have shown that phenytoin negatively affects neurodevelopment of children exposed to phenytoin in the womb, while other studies have not found such an effect. The possibility of an effect on neurodevelopment cannot be ruled out. There have been isolated reports of tumours, including tumours affecting nerve tissue, in children whose mothers received phenytoin during pregnancy. If you take Epanutin during pregnancy, your baby is at risk for bleeding problems right after birth. Your doctor may give you and your baby a medicine to prevent this. Moreover, your child should be closely monitored. Contraception in women If you are a woman of childbearing age and are not planning a pregnancy, you should use effective contraception during treatment with Epanutin. Epanutin may affect how hormonal contraceptives, such as the contraceptive (birth control) pill, work and make them less effective at Page 5 of 9 preventing pregnancy. Talk to your doctor, who will discuss with you the most suitable type of contraception to use while you are taking Epanutin. If you are a woman of childbearing age and are planning a pregnancy, talk to your doctor before you stop contraception and before you become pregnant about switching to other suitable treatments in order to avoid exposing the unborn baby to phenytoin. If you are or think you might be pregnant, tell your doctor straight away. You should not stop taking your medicine until you have discussed this with your doctor. Stopping your medication without consulting your doctor could cause seizures which could be dangerous to you and your unborn child. Your doctor may decide to change your treatment. Closer monitoring of your unborn child is also recommended. Breast-feeding Epanutin passes into breast milk. You should not breast-feed if you are taking Epanutin.
