Pregnancy and breast-feeding Women who could become pregnant

Before you start taking Epilim Crushable, your doctor should discuss with you the possible problems when it is taken in pregnancy.

  • Unplanned pregnancy is not desirable in women taking Epilim Crushable
  • You should use an effective method of contraception and talk to your doctor before planning pregnancy. Epilim Crushable has no effect on how well the ora contraceptive pill works.

Well before you become pregnant it is important to discuss pregnancy and epilepsy with your doctor and, if you have one, your epilepsy specialist. This is to make sure that you and your doctor agree that you should have Epilim if you become pregnant. Women taking Epilim during pregnancy have a higher risk than other women of having a child with an abnormality. The chance of abnormalities is increased if you are also taking other medicines for epilepsy at the same time. These abnormalities include:

  • Head and face deformities including cleft palate (a gap or depression in the lip)
  • Deformities of the bones, including hip dislocation
  • Malformations of the arms and legs
  • Deformities of the tube from the bladder to the penis, where the opening is formed in a different place
  • Heart and blood vessel malformations, including heart defects
  • Defects of the lining of the spinal cord
  • An abnormality of the spinal cord called ‘Spina bifida’

Women who take Epilim Crushable during pregnancy may be more likely to have a baby with spina bifida. Taking folic acid 5mg each day as soon as you stop contraception may lower the risk of having a baby with spina bifida.

There is also an increased risk of other birth defects. These other defects can usually be detected in the first 3 months of the pregnancy using routine antenatal screening blood tests and ultrasound scans.

Pregnant mothers who take Epilim Crushable may have babies with blood clotting problems (such as blood not clotting or not clotting very well). This may appear as bruising or bleeding which takes a long time to stop.

Some babies born to mothers who took Epilim Crushable during pregnancy may develop less quickly than normal or have autistic disorders. These children may require additiona educational support.

Talk to your doctor before you stop taking Epilim Crushable if you want to become pregnant. Do not stop taking Epilim Crushable suddenly, as it is likely that your fits will come back.
