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
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
is unlikely that it will reduce the risk of birth defects
associated with valproate use.
Do not stop using your contraception before you have
talked to your doctor and worked together on a plan to
ensure your epilepsy 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
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.

Do not take Epilim Chrono and tell your doctor if:
Some medicines used for pain and inﬂammation
(salicylates) such as aspirin.
Some other medicines used to treat ﬁts (epilepsy) – see
page 2, section 3, “Patients taking other medicines for
‘ﬁts’”. This includes medicines such as phenobarbital,
primidone, phenytoin, carbamazepine, topiramate,
lamotrigine and felbamate.
Epilim Chrono may increase the effect of the
Epilim Chrono contains sodium valproate. It belongs to a
group of medicines called anti-convulsants or anti-epileptic
agents. It works by helping to calm the brain down.
What Epilim Chrono is used for
What is in this leaflet
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
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 every 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
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.
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.
Make sure you read the patient booklet and sign the
Acknowledgement of Risk form which should be given
to you and discussed with you by your doctor or

Driving and using machines:
You may feel sleepy when taking Epilim Chrono. If this
happens to you, do not drive or use any tools or machines.
Taking other medicines used to treat ﬁts or calm emotional
and mental health problems may increase sleepiness.
