1.WHAT SODIUM VALPROATE IS AND WHAT IT IS USED FOR
The name of your medicine is Sodium Valproate Zentiva 200mg/5ml Liquid (called sodium
valproate throughout this leaflet). This belongs to a group of medicines called
anti-convulsants or anti-epileptic agents. It works by controlling the activity of the brain
which causes fits or seizures.
It is used to treat epilepsy (fits) in adults and children.

2. WHAT YOU NEED TO KNOW BEFORE YOU TAKE SODIUM VALPROATE

302273 - 273

Do not take sodium valproate and tell your doctor if:
• You are allergic (hypersensitive) to sodium valproate or any of the other ingredients of this
medicine (listed in section 6)
Signs of an allergic reaction include: a rash, swallowing or breathing problems, swelling of your
lips, face throat or tongue
• You have liver problems or a family history of liver problems
• You have a rare illness called porphyria which affects your metabolism
• You have a genetic problem caused by a mitochondrial disorder (e.g. Alpers-Huttenlocher
syndrome)
Talk to your doctor or pharmacist before taking sodium valproate if:
• You have diabetes. This medicine may affect the results of urine tests
• You have kidney problems – you may need a lower dose
• You have a ‘urea cycle disorder’ - where too much ammonia builds up in the body
• You have an illness called “lupus” – a disease of the immune system which affects the skin,
bones, joints, lungs and kidneys
• You know that there is a genetic problem caused by a mitochondrial disorder in your family
Talk to your doctor or pharmacist before taking sodium valproate if you have these
conditions. Do this even if you no longer have them, but have had them in the past.
Sodium valproate can increase your appetite and may make you put on weight. Talk to
your doctor about how this will affect you.
Your doctor may wish to do blood tests before you start taking sodium valproate and
during the first six months of treatment.
Warnings and precautions
A small number of people being treated with anti-epileptics such as sodium valproate
have had thoughts of harming or killing themselves. If at any time you have these
thoughts, immediately contact your doctor.

Other medicines and sodium valproate
Please tell your doctor or pharmacist if you are taking or have recently taken any other
medicines, including medicines obtained without a prescription. This includes herbal
medicines. This is because sodium valproate can affect the way some other medicines
work. Also some medicines can affect the way sodium valproate works.
In particular, check with your doctor or pharmacist if you are taking any of the following
medicines:
• 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
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 for depression – including monoamine oxidase inhibitors (MAOI) such as
moclobemide.
• Benzodiazepines (such as Diazepam) – used as sleeping tablets and for anxiety.
• Some medicines for epilepsy such as phenytoin, carbamazepine, topiramate, phenobarbital,
lamotrigine, primidone, felbamate.
• Medicines for thinning the blood such as warfarin.
• Salicylates such as aspirin
• Cholestyramine – for high blood lipid (fat) levels.
• Cimetidine - for stomach ulcers.
• Carbapenem agents (antibiotics used to treat bacterial infections) such as imipenem,
meropenem, rifampicin and erythromycin. The combination of sodium valproate and
carbapenems should be avoided because it may decrease the effect of your medicine.
• Mefloquine and chloroquine – used to prevent and treat 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.
• Zidovudine – for HIV and AIDS.
• Temozolomide – for cancer.
Taking sodium valproate with food and drink
Take sodium valproate with or after food. This will help to stop the feelings of sickness
that may happen after taking the medicine.
Alcohol intake is not recommended during treatment.
Pregnancy, breast feeding and fertility
Important advice for women
• Valproate can be harmful to unborn children when taken by a woman during pregnancy.
• Whether taken on its own or with another epilepsy medicine, valproate seems to carry a higher
risk if taken during pregnancy than other epilepsy medicines. 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 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 (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 it 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 is 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 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.
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.
Breast-feeding
Very little sodium valproate gets into the breast milk. However, talk to your doctor about
whether you should breastfeed your baby. Ask your doctor or pharmacist for advice
before taking any medicine.
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 benzodiazepines.
If this happens to you, do not drive or use any tools or machines.
Important information about some the ingredients of sodium valproate
This liquid contains:
• A colour called ‘ponceau 4R aluminium lake (E124)’: This may cause allergic reactions
including asthma in some people. You are more likely to have an allergy if you are also allergic
to aspirin
• Sodium methyl hydroxybenzoate and sodium propyl hydroxybenzoate: This may cause
allergic reactions (these may not happen straight away)
• Sorbitol: This is a type of sugar. If you have been told by your doctor that you cannot tolerate
some sugars, talk to your doctor before taking the liquid

3. HOW TO TAKE SODIUM VALPROATE
Always take sodium valproate exactly as your doctor has told you. You should check with your
doctor or pharmacist if you are not sure.
Sodium valproate treatment must be started and supervised by a doctor specialised in the
treatment of epilepsy.

Taking this medicine
• Sodium valproate should be swallowed with or after food. This will help reduce the chances of
getting certain side effects such as nausea or upset stomach.
• You will be able to measure the dose in the measuring cup supplied with the liquid.
• The marks of the cup show you how to measure between 5ml (200mg) and 15ml (600mg)
• If the dose is less than 5ml (200mg), talk to your doctor or pharmacist about how to measure
the dose.
• Do not mix sodium valproate with any other liquids. Do not dilute this medicine.
How much to take
Adults
• The usual dose of sodium valproate is between 1000mg and 2000mg each day.
• This may be increased to 2500mg each day.
• Take this in 2 separate doses – half in the morning and half in the evening.
Children over 20kg:
• The dose of sodium valproate is based on the child’s weight.
• The usual dose is between 20 and 30mg for each kg of body weight.
• This may be increased to 35mg for each kg of body weight each day.
• Take this in 2 separate doses – half in the morning and half in the evening.
Children under 20kg:
• The usual dose of sodium valproate is based on the child’s weight.
• The usual dose is 20mg for each kg of body weight.
• Give in 2 separate doses – half in the morning and half in the evening.
People with kidney problems
If you or your child have kidney disease, your doctor may prescribe a lower dose.
Do not change the dose you have been prescribed without first discussing with your doctor.
When treatment is first started
At first 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 then increase the
dosage until your condition is controlled.
• Because of this it is very important that you follow your doctor’s instructions about how much
to take.
• Blood tests may be needed to check how well the medicine is working.
• You may be taking other medicines for epilepsy at the same time as sodium valproate. If so,
your doctor may increase the dose of sodium valproate by 5 to 10mg for each kg of body
weight each day.
Appointments
Make sure you keep your regular appointments for a check-up. They are very important
as your dose may need to be changed. If you go into hospital or visit another doctor or a
dentist, tell them you are taking sodium valproate.
If you take more sodium valproate than you should
An overdose of this medicine may be dangerous. If you think you may have taken more
sodium valproate than you should (or someone else has taken some), talk to a doctor,
pharmacist or go to the nearest hospital casualty department straight away. Take the
medicine bottle with you.
The following effects may happen: feeling sick or being sick, pupils of the eye become
smaller, dizziness, loss of consciousness, weak muscles and poor reflexes, breathing
problems, headaches, fits (seizures), confusion, memory loss and unusual or inappropriate
behaviour.
If you forget to take sodium valproate
If you forget to take a dose at the right time, take it as soon as you remember. Then go
on as before. Do not take a double dose to make up for a forgotten dose.
If you stop taking sodium valproate
Do not stop taking sodium valproate without first discussing this with your doctor, even if
you feel better. This is because stopping suddenly may lead to your fits coming back.
If you have any further questions on the use of this product, ask your doctor or pharmacist.

4. POSSIBLE SIDE EFFECTS
Like all medicines, sodium valproate can cause side effects, although not everybody gets them.
Usually they are not serious, and may stop if you change to another medicine.
Stop taking sodium valproate and see a doctor or go to a hospital straight away if:
• You get swelling of the face, lips or throat which may cause difficulty in swallowing or
breathing. Hands, feet or genitals may also be affected. More severe allergic reactions can
lead to lymph node enlargement and possible impairment of other organs. You could also
notice an itchy, lumpy rash (hives), nettle rash (urticaria), joint pain or fever (systemic lupus
erythematosus). This may mean you are having an allergic reaction to sodium valproate
