Mania occurs in an illness called ‘bipolar
disorder’. Sodium Valproate can be used
when lithium can not be used.

Children and adolescents
Children and adolescents under 18 years
of age:
Sodium Valproate should not be used for
children and adolescents below 18 years
of age for the treatment of mania.
Your doctor may wish to do blood tests
before you start and during the first six
months of your treatment to:
• check your levels of Sodium Valproate
• check for blood or liver problems,
especially in children under 3 years of
age, or patients who suffer from severe
seizures, have brain disease and/or
learning disabilities, or have a history of
liver disease
• your doctor may do regular blood tests
and liver function tests before and
during your treatment with this
Taking other medicines
In particular, tell your doctor or nurse if
you are taking any of the following
• any other anti-epileptics e.g. phenytoin,
phenobarbital, carbamazepine,
lamotrigine, topiramate, primidone,
• any anti-depressant medicines including
monoamine oxidase inhibitors
• 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
• benzodiazepines (used as sleeping
tablets and to treat anxiety)
• antibiotics such as erythromycin,
• 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 blood)
carbapenem agents (antibiotic used to
treat bacterial infection). 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).

Please tell your doctor or pharmacist if
you are taking or have recently taken any
other medicines, including medicines
obtained without a prescription.
Taking Sodium Valproate Tablets with food
and drink
Take Sodium Valproate tablets with or
after food. This will help to stop the
feelings of sickness that may happen after
taking the tablet.
Pregnancy and breast-feeding
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
• 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 2

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
• 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 5 mg 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
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.
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.
Driving and using machines
You may feel sleepy:
• when you first start taking Sodium
• if you are taking it with other medicines,
such as other antiepileptic drugs or
