What Epilim Chronosphere is and what it is used for
What Epilim Chronosphere is
The name of your medicine is Epilim Chronosphere 100mg modified release
granules. “Modified release” means that the active ingredients (sodium
valproate and valproic acid) are slowly released from the granules over a
long period of time.
What Epilim Chronosphere contains
Epilim Chronosphere contains two medicines called sodium valproate and
valproic acid. Both belong to a group of medicines called anti-convulsants or
anti-epileptic agents. They work by helping to calm the brain down.
What Epilim Chronosphere is used for
Epilim Chronosphere is used to treat epilepsy (fits) in adults and children.
What you need to know before you take Epilim

Warnings and precautions
A small number of people being treated with anti-epileptics such as sodium

you have these thoughts, immediately contact your doctor.
As with other antiepileptic drugs, convulsions may become worse or happen
more frequently whilst taking this medicine. If this happens contact your

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 Epilim Chronosphere.
Taking Epilim Chronosphere 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 Epilim
Chronosphere and during your treatment.
Other medicines and Epilim Chronosphere
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 Chronosphere can affect
the way some other medicines work. Also some medicines can affect the
way Epilim Chronosphere works.
The following medicines can increase the chance of you getting side
effects, when taken with Epilim Chronosphere:
* 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 Chronosphere may increase the effect of the following
* 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,
* Medicines used to calm emotional and mental conditions such as
diazepam and olanzapine
The following medicines can affect the way Epilim Chronosphere
* 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 Chronosphere and carbapenems should be avoided because it may
decrease the effect of your medicine.
* Colestyramine used to lower blood fat (cholesterol) levels
Taking Epilim Chronosphere 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
* Valproate carries a risk if taken during pregnancy. The higher the dose, the
higher the risks but all doses carry a risk.
* 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
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
* 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
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.
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
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
* 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 Chronosphere gets into the breast milk. However, talk to
your doctor about whether you should breast-feed your baby.

Driving and using machines:
You may feel sleepy when taking Epilim Chronosphere. 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 problems may increase sleepiness.
