What Epilim Chrono is and what it is used for
What Epilim Chrono is
The name of your medicine is Epilim Chrono 200, 300 and 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.
What Epilim Chrono is used for
Epilim Chrono is used to treat epilepsy (fits) in adults and children.
What you need to know before you take Epilim Chrono
Do not take Epilim Chrono and tell your doctor if:
X You are allergic (hypersensitive) to sodium valproate or any of the other ingredients of Epilim
Chrono (see Section 6: Contents of the pack and other information).
Signs of an allergic reaction include: a rash, swallowing or breathing problems, swelling of your
lips, face, throat or tongue.
X You have liver problems or you or your family have a history of liver problems.
X 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.
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.
• As with other anti-epileptic drugs, convulsions may become worse or happen more frequently
whilst taking this medicine.
If this happens contact your doctor immediately.
Talk to your doctor or pharmacist before taking Epilim Chrono if:
• You have diabetes. This medicine may affect the results of urine tests.
• You have a carnitine palmitoyltransferase type II deficiency.
• 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.
• You know that there is a genetic problem caused by a mitochondrial disorder in your family.
If you are not sure if any of the above apply to you, talk to your doctor or pharmacist before taking
Taking Epilim Chrono may make you put on weight. Talk to your doctor about how this will affect
Your doctor may wish to do blood tests before you start taking Epilim Chrono and during your
Other medicines and Epilim Chrono
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.
The following medicines can increase the chance of you getting side effects, when taken with
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, rufinamide, topiramate, acetazolamide, 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 health problems (including schizophrenia,
bipolar disorder and depression) such as quetiapine, diazepam and olanzapine.
• Propofol – used for anaesthesia.
The following medicines can affect the way Epilim
• Some medicines used for the prevention and treatment of malaria such as mefloquine and
• Cimetidine used for stomach ulcers.
• Protease inhibitors such as lopinavir and ritonavir – used for HIV infection and AIDS.
• 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.
• Cholestyramine used to lower blood fat (cholesterol) levels.
Taking Epilim Chrono with food and drink
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.
• Valproate carries a risk if taken during pregnancy. 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
• 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 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 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 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.
• 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.
• 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
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 sleepiness.

How much to take
Adults (including the elderly)
The starting dose is 600mg daily. Your doctor will gradually increase this dose by 200mg
every 3 days depending on your condition.
The usual dose is generally between 1000mg and 2000mg (20-30mg per kilogram of body
weight) each day.
This may be increased to 2500mg each day depending on your illness.
Children over 20 kilograms
• The starting dose should be 400mg daily. Your doctor should increase this dose depending
on your child’s illness.
• The usual dose is then between 20mg and 30mg for each kilogram of body weight each
• This may be further increased to 35mg for each kilogram of body weight each day
depending on your child’s illness.
Children under 20 kilograms
Epilim Chrono is not recommended in children that weigh less than 20 kilograms. Epilim Liquid
(sugar free) or Epilim Syrup is recommended instead.
Patients with kidney problems
• Your doctor may decide to adjust your or your child’s dose.
Patients taking other medicines for fits (epilepsy)
• You or your child may be taking other medicines for epilepsy at the same time as Epilim
Chrono. If so, your doctor should gradually initiate treatment depending on your or your
• Your doctor may increase the dose of Epilim Chrono by 5 to 10mg for each kilogram of
body weight each day depending on which other medicines you are taking.
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.
Possible side effects
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’.

skin over the body. Also a feeling of being generally unwell, fever, chills, and aching muscles.
This may be something called ‘Toxic epidermal necrolysis’.
• Bruising more easily and getting more infections than usual. This could 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.
• Changes in mood, loss of memory, lack of concentration and deep loss of consciousness (coma).
• Underactive thyroid gland, which may cause tiredness or weight gain (hypothyroidism).
• Breathing difficulty and pain due to inflammation of the lungs (pleural effusion).
Tell your doctor as soon as possible if you have any of the following side effects:
• Changes in behaviour including being very alert, and sometimes also aggressive, hyperactive

phenobarbital and topiramate are taken at the same time or if the Epilim Chrono starting dose
is high or has been suddenly increased.
• Changes in the amount of ammonia in the blood.
Symptoms of this condition are being sick, problems with balance and co-ordination, feeling
lethargic or less alert.
• Feeling shaky (tremor), sleepy or unsteady when walking or jerky muscle movements.
