What Sodium Valproate is and what it is used for
Sodium Valproate Teva Gastro-resistant Tablets contain the active ingredient Sodium Valproate, which
belongs to a group of medicines known as anticonvulsants.
Sodium Valproate is a medicine for the treatment of epilepsy and mania. Sodium Valproate may be taken
either on its own as your only treatment for epilepsy or you may take it together with another epilepsy
Sodium Valproate is used in the treatment of mania, where you may feel very excited, elated, agitated,
enthusiastic or hyperactive. Mania occurs in an illness called ‘bipolar disorder’. Sodium Valproate can
be used when lithium can not be used.

Other medicines and Sodium Valproate
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.
any other anti-epileptics e.g. phenytoin, phenobarbital, carbamazepine, lamotrigine, topiramate,
any anti-depressant medicines including monoamine oxidase inhibitors (MAOI) such as
moclobemide, selegiline, linezolid
anti-psychotic agents - for mental health problems. Sodium Valproate may increase the effects of
these drugs. In particular, when taken with the medicine olanzapine the following effects may occur:
neutropenia (a blood problem which reduces the chance of fighting infection), tremor, dry mouth,
increased appetite and weight gain, problems with speech, sleepiness or extreme tiredness
Medicines used to calm emotional and mental conditions such as diazepam and olanzapine
antibiotics such as erythromycin, rifampicin,
chloroquine or mefloquine (for malaria). Taking these with Sodium Valproate may increase the
chance of a fit. Before travelling to a malaria area, ask your doctor or pharmacist about the best
malaria prevention tablets for you
cimetidine (for the treatment of stomach ulcers) or colestyramine (to treat high levels of fat in the
carbapenem agents (antibiotic used to treat bacterial infection) such as imipenem, meropenem,
rifampicin and erythromycin. The combination of valproic acid and carbapenems should be avoided
because it may decrease the effect of Sodium Valproate
drugs that prevent blood clotting such as aspirin or warfarin
zidovudine (used to treat HIV and AIDS)
temozolomide (used to treat cancer).
Sodium Valproate with food, drink and alcohol
Alcohol intake is not recommended during treatment.
Take Sodium Valproate Tablets with or after food. This will help to stop the feelings of sickness that
may happen after taking the tablets.
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.
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. It can cause serious birth defects and can
affect the way in which the child develops as it grows; these abnormalities include:
Page 3 of 12
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
heart and blood vessels malformations with heart defects
abnormalities in the lining of nerve tubes with holes or protrusions
spina bifida (where the bones of the spine are not properly developed).
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
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
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
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.
Page 4 of 12
• 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
• 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.
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 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
• Make sure you are using an effective method of contraception
Page 5 of 12
• 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.
• 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.
• 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.
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 pharmacist.
Driving and using machines
You may feel sleepy:
when you first start taking Sodium Valproate
if you are taking it with other medicines, such as other antiepileptic drugs or

3. How to take Sodium Valproate
Sodium Valproate treatment must be started and supervised by a doctor specialised in the treatment
of epilepsy or bipolar disorders. Always take this medicine exactly as your doctor or pharmacist
has told you. Check with your doctor or pharmacist if you are not sure.
These tablets have been coated with a substance that will allow them to pass through the stomach
The tablets should be swallowed preferably with a drink of water usually after meals. These
tablets should not be chewed or crushed.
The recommended dose is:
Initially 600 mg daily, increasing by 200 mg at three-day intervals until control of fits is achieved.
This may be increased up to a maximum of 2500 mg per day. This quantity may be given in one
dose or can be divided and taken in two separate doses e.g. half in the morning and half in the
Children over 20 kg
Initially 400 mg daily. The doctor will adjust the dose of Sodium Valproate for your child based on
the child’s body weight until control of fits is achieved. This quantity may be given in one dose or
can be divided and given in two separate doses e.g. half in the morning and half in the evening.
Children under 20 kg
The doctor will calculate the appropriate dose of Sodium Valproate for your child based on the
child’s body weight.
Older people and patients with kidney problems
Your doctor will decide a suitable dose to achieve adequate control of your epilepsy.
When treatment is first started, you may be prescribed a lower dose. This is because some patients
need less Sodium Valproate than others to control their fits. Your doctor will increase the dosage
until your condition is controlled. Because of this, it is very important that you follow the
instructions your doctor has given you about how much to take.
The daily dosage should be established and controlled individually by your doctor.
• The recommended initial daily dose is 750 mg.
Mean daily dose
• The recommended daily doses usually range between 1000 mg and 2000 mg.
Taking Sodium Valproate together with another therapy:
You may be taking other drugs to control your epilepsy at the same time as Sodium Valproate. If
you are, your doctor may increase the dose of Sodium Valproate.
