other
Tell your doctor or pharmacist if you are taking, have recently taken or might take any medicines.
Sodium Valproate with food and drink
Take Sodium Valproate Syrup with or after food. This will help to stop the feelings of sickness that may happen after taking the syrup.
Pregnancy, breast-feeding and fertility
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
Pregnancy
Information for women who are pregnant, planning to become pregnant, or who could become pregnant
Before you start taking Sodium Valproate , your doctor should discuss with you the possible problems when it is taken in pregnancy.
• Unplanned pregnancy is not desirable in women receiving Sodium Valproate
• You should not take this medicine if you are pregnant or a women of child-bearing age unless explicitly advised by your doctor. If you are a woman of child-bearing age, you have to use effective contraception during treatment. Sodium Valproate has no effect on how well the oral contraceptive pill works.
Women taking Sodium Valproate 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 antiepileptic medicines at the same time. These abnormalities include:
• Head and face deformities including cleft palate, a gap or depression in the lip
• Malformations of the arms and legs
• Deformities of the bones, including hip dislocation
• Deformities of the tube from the bladder to the penis where the opening is formed in a different place
• Heart and blood vessels malformations with heart defects
• Abnormalities in the lining of nerve tubes with holes or protrusions
• Spina bifida
Women who take Sodium Valproate during pregnancy may be more likely to have a baby with spina bifida. This is an abnormality of the spinal cord. 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 Sodium Valproate may have babies with blood clotting problems (such as blood not clotting or not clotting very well). This may appear as bruising or a bleeding which takes a long time to stop. Some babies born to mothers who took Sodium Valproate during pregnancy may develop less quickly than normal. These children may require additional educational support.
Talk to your doctor before stopping taking Sodium Valproate if you want to become pregnant. It is important not to stop your Sodium Valproate suddenly, as it is likely that your fits will come back.
Women who are planning to get Pregnant
If you become pregnant, think you may be pregnant or plan to become pregnant while taking Sodium Valproate , you must tell your doctor straight away.
• Your doctor will give you appropriate counselling and will suggest changes to your treatment or dose
• He or she will also want to check your progress while you are pregnant.
It is very important that you discuss your treatment with your doctor well before you become pregnant.
Breast-feeding
Very little Sodium Valproate gets into the breast milk. However, talk to your doctor about whether you should breast feed your baby. Ask your doctor or pharmacist for advice before taking any medicine.
Important advice for women
• Valproate can be harmful to unborn children when taken by a woman during pregnancy.
• Valproate carries a risk if taken during pregnancy. The higher the dose, the higher the risks but all doses carry a risk.
• It can cause serious birth defects and can affect the way in which the child develops as it grows. Birth defects which have been reported include spina bifida (where the bones of the spine are not properly developed); facial and skull malformations; heart, kidney, urinary tract and sexual organ malformations; limb defects.
• If you take valproate during pregnancy you have a higher risk than other women of having a child with birth defects that require medical treatment. Because valproate has been used for many years we know that in women who take valproate around 10 babies in every 100 will have birth defects. This compares to 2-3 babies in ever 100 born to women who don’t have epilepsy.
• It is estimated that up to 30-40% of preschool children whose mothers took valproate during pregnancy may have problems with early childhood development. Children affected can be slow to walk and talk , intellectually less able than other children, and have difficulty with language and memory.
• Autistic spectrum disorders are more often diagnosed in children exposed to valproate and there is some evidence children may be more likely to develop symptoms of Attention Deficit Hyperactivity Disorder (ADHD).
• If you are a woman capable of becoming pregnant your doctor should only prescribe valproate for you if nothing else works for you.
• Before prescribing this medicine to you, your doctor will have explained what might happen to your baby if you become pregnant whilst taking valproate. If you decide later you want to have a child you should not stop taking your medicine until you have discussed this with your doctor and agreed a plan for switching you onto another product if this is possible.
• Ask your doctor about taking folic acid when trying for a baby. Folic acid can lower the general risk of spina bifida and early miscarriage that exists with all pregnancies. However, it is unlikely that it will reduce the risk of birth defects associated with valproate use.
FIRST PRESCRIPTION
If this is the first time you have been prescribed valproate your doctor will have explained the risks
to an unborn child if you become pregnant. Once you are of childbearing age, you will need to make
sure you use an effective method of contraception throughout your treatment. Talk to your doctor or
family planning clinic if you need advice on contraception.
Key messages:
• Make sure you are using an effective method of contraception.
• Tell your doctor at once if you are pregnant or think you might be pregnant.
CONTINUING TREATMENT AND NOT TRYING FOR A BABY
If you are continuing treatment with valproate but you don’t plan to have a baby make sure you are using an effective method of contraception. Talk to your doctor or family planning clinic if you need advice on contraception.
Key messages:
• Make sure you are using an effective method of contraception
• Tell your doctor at once if you are pregnant or think you might be pregnant.
CONTINUING TREATMENT AND CONSIDERING TRYING FOR A BABY
If you are continuing treatment with valproate and you are now thinking of trying for a baby you must not stop taking either your valproate or your contraceptive medicine until you have discussed this with your prescriber. You should talk to your doctor well before you become pregnant so that you can put several actions in place so that your pregnancy goes as smoothly as possible and any risks to you and your unborn child are reduced as much as possible.
Your doctor may decide to change the dose of valproate or switch you to another medicine before you start trying for a baby.
If you do become pregnant you will be monitored very closely both for the management of your underlying condition and to check how your unborn child is developing.
Ask your doctor about taking folic acid when trying for a baby. Folic acid can lower the general risk of spina bifida and early miscarriage that exists with all pregnancies. However, it it unlikely that it will reduce the risk of birth defects associated with valproate use.
Key messages:
• Do not stop using your contraception before you have talked to your doctor and worked together on a plan to ensure your epilepsy/bipolar disorder is controlled and the risks to your baby are reduced.
• Tell your doctor at once when you know or think you might be pregnant.
UNPLANNED PREGNANCY WHILST CONTINUING TREATMENT
Babies born to mothers who have been on valproate are at serious risk of birth defects and problems with development which can be seriously debilitating. If you are taking valproate and you think you are pregnant or might be pregnant contact your doctor at once. Do not stop taking your medicine until your doctor tells you to.
Ask your doctor about taking folic acid. Folic acid can lower the general risk of spina bifida and early miscarriage that exists with all pregnancies. However, it is unlikely that it will reduce the risk of birth defects associated with valproate use.
Key messages:
• Tell your doctor at once if you know you are pregnant or think you might be pregnant.
• Do not stop taking valproate unless your doctor tells you to.
