What Epilim Chrono is
The name of your medicine is Epilim Chrono 500mg Controlled Release
Tablets (called Epilim Chrono in this leaflet). “Controlled release” means
that the active ingredient sodium valproate is slowly released from the
tablets over a period of time.
What Epilim Chrono contains
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.

Taking Epilim Chrono with food and drink
Alcohol intake is not recommended during treatment.
Pregnancy and breast-feeding
Women who could become pregnant
You should not take this medicine if you are pregnant or a women
of child-bearing age unless explicitly advised by your doctor.
Before you start taking Epilim Chrono, your doctor should discuss with
you the possible problems when it is taken in pregnancy.
• Unplanned pregnancy is not desirable in women taking Epilim Chrono
• You should use an effective method of contraception and talk to
your doctor before planning pregnancy.
Epilim Chrono has no effect on how well the oral contraceptive pill works.
Well before you become pregnant it is important to discuss pregnancy
and epilepsy with your doctor and, if you have one, your epilepsy
specialist. This is to make sure that you and your doctor agree that you
should have Epilim if you become pregnant.
Women taking Epilim 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 medicines for
epilepsy at the same time. These abnormalities include:
• Head and face deformities including cleft palate (a gap or depression
in the lip)
• Deformities of the bones, including hip dislocation
• Malformations of the arms and legs
• Deformities of the tube from the bladder to the penis, where the
opening is formed in a different place
• Heart and blood vessel malformations with heart defects
• Defects of the lining of the spinal cord
• An abnormality of the spinal cord called ‘Spina bifida’
• Malformations of the urethra

What Epilim Chrono is used for
Epilim Chrono is used to treat epilepsy (fits) in adults and children.
Do not take Epilim Chrono and tell your doctor if:
• You are allergic (hypersensitive) to sodium valproate or any of the
other ingredients of Epilim Chrono (see Section 6: Further information)
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 you or your family have a history of liver
• You have a rare illness called porphyria
Do not take this medicine if any of the above apply to you. If you are not
sure, talk to your doctor or pharmacist before taking Epilim Chrono.
Take special care with Epilim Chrono
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.
Check with your doctor or pharmacist before taking this medicine if:
• You have diabetes. This medicine may affect the results of urine tests
• You have kidney problems. Your doctor may give you a lower dose
• You have fits (epilepsy), brain disease or a metabolic condition
affecting your brain
• You have a ‘urea cycle disorder’ where too much ammonia builds up in
the body
• You have an illness called “systemic lupus erythematosus (SLE)” - a
disease of the immune system which affects skin, bones, joints and
internal organs
If you are not sure if any of the above apply to you, talk to your doctor or
pharmacist before taking Epilim Chrono.
Weight gain
Taking Epilim Chrono may make you put on weight. Talk to your doctor
about how this will affect you.
Blood tests
Your doctor may wish to do blood tests before you start taking Epilim
Chrono and during your treatment.
Taking Epilim Chrono with other medicines
Please tell your doctor or pharmacist if you are taking or have recently
taken any other medicines. This includes medicines you buy without a
prescription, including herbal medicines. This is because Epilim Chrono
can affect the way some other medicines work. Also some medicines can
affect the way Epilim Chrono works.

Women who take Epilim Chrono during pregnancy may be more likely to
have a baby with spina bifida. 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 Epilim Chrono may have babies with:
• Blood clotting problems (such as blood not clotting or not clotting very
well). This may appear as bruising or bleeding which takes a long time
to stop.
• Hypoglycaemia (low blood sugar)
• Hypothyroidism (underactive thyroid gland, which can cause tiredness
or weight gain).
Some babies born to mothers who took Epilim Chrono during pregnancy
may develop less quickly than normal or have autistic disorders. These
children may require additional educational support.
Talk to your doctor before you stop taking Epilim Chrono if you want to
become pregnant. Do not stop taking Epilim Chrono 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 Epilim Chrono, you must tell your doctor straight
• 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 Epilim Chrono 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 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

The following medicines can increase the chance of you getting
side effects, when taken with Epilim Chrono:
• Some medicines used for pain and inflammation (salicylates) such as
• 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 following medicines:
• Medicines used for thinning the blood (such as warfarin)
• Zidovudine used to treat HIV infection
• Temozolomide used to treat cancer
• Medicines for depression
• Monoamine oxidase inhibitors (MAOI) such as moclobemide,
selegiline, linezolid
• Medicines used to calm emotional and mental conditions such as
diazepam and olanzapine
The following medicines can affect the way Epilim Chrono works:
• Some medicines used for the prevention and treatment of malaria such
as mefloquine and chloroquine
• Cimetidine used for stomach ulcers
• Carbapenem agents (antibiotics used to treat bacterial infections) such
as imipenem, meropenem, rifampicin and erythromycin. The
combination of Epilim Chrono and carbapenems should be avoided
because it may decrease the effect of your medicine.
• Colestyramine used to lower blood fat (cholesterol) levels

Always take Epilim Chrono exactly as your doctor has told you. You
should check with your doctor or pharmacist if you are not sure.

If you take more Epilim Chrono than you should
If you take more Epilim Chrono than you should, tell a doctor or go to a
hospital casualty department straight away. Take the medicine pack with
you. This is so the doctor knows what you have taken.
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 Epilim Chrono
If you forget to take a dose, take it as soon as you remember. However, if
it is nearly time for the next dose, skip the missed dose. Do not take a
double dose to make up for a forgotten dose.
If you stop taking Epilim Chrono
Keep taking until your doctor tells you to stop.
Do not stop taking Epilim Chrono just because you feel better.
If you stop your fits may come back.
Make sure you or your child keep your regular appointments for a check
up. They are very important as your or your child’s dose may need to be
changed. Epilim Chrono can change the levels of liver enzymes shown
up in blood tests. This can mean that your or your child’s liver is not
working properly.
If you or your child go into hospital or visit another doctor or a dentist, tell
them you are taking Epilim Chrono.
If you have any further questions on the use of this product, ask your
doctor or pharmacist.
Like all medicines, Epilim Chrono can cause side effects, although not
everybody gets them.
Tell your doctor straight away if you notice any of the following
serious side effects - you may need urgent medical treatment:
• You have an allergic reaction. The signs include: a rash, joint pain,
fever (systemic lupus erythematosus), swallowing or breathing
problems, swelling of your lips, face, throat or tongue. Hands, feet or
genitals may also be affected. More severe allergic reactions can lead
to lymph node enlargement and possible impairment of other organs.
• Liver problems and problems of the pancreas may show as a sudden
illness which may happen in the first six months of treatment. This
happens in a very small number of people taking Epilim Chrono. It
includes feeling and being sick many times, being very tired, sleepy
and weak, stomach pain including very bad upper stomach pain,
jaundice (yellowing of the skin or whites of the eyes), loss of appetite,
swelling (especially of the legs and feet but may include other parts of
the body), worsening of your fits or a general feeling of being unwell.
Your doctor may tell you to stop taking Epilim Chrono immediately if
you have these symptoms
• You have a skin rash or skin lesions with a pink/red ring and a pale
centre which may be itchy, scaly or filled with fluid. The rash may
appear especially on the palms or soles of your feet. These could be
signs of a serious allergy to the medicine called ‘erythema multiforme’

and genitals. Also flu-like symptoms and fever. This may be something
called ‘Stevens-Johnson syndrome’

large areas of raw exposed skin over the body. Also a feeling of being
generally unwell, fever, chills and aching muscles. This may be
something called ‘Toxic epidermal necrolysis’

be a blood problem called ‘thrombocytopenia’. It can also be due to a
fall in the number of white blood cells, bone marrow depression or
another condition that affects red blood cells, white blood cells and
platelets (pancytopenia) or how the blood clots
• Blood clotting problems (bleeding for longer than normal), bruising or
bleeding for no reason
