Take special care with Epilim Chronosphere
A small number of people being treated with antiepileptics such as sodium valproate have had
thoughts of harming or killing themselves. If at any time you
have these thoughts, immediately contact your doctor.

 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 a „urea cycle disorder‟ - where too much
ammonia builds up in the body.

(SLE)” a disease of the immune system which affects
skin, bones, joints and internal organs.

lamotrigine and felbamate
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.

Do not take Epilim Chronosphere and tell your
doctor if:
 You are allergic (hypersensitive) to sodium
valproate, valproic acid or any of the other ingredients of
Epilim Chronosphere (listed in Section 6 below).
 You have liver problems or you and your family have a
history of liver problems
 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 Chronosphere.

Epilim Chronosphere 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
Chronosphere 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 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 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 Chronosphere, your doctor
should discuss with you the possible problems when it is
taken in pregnancy.
 Unplanned pregnancy is not desirable in women taking
Epilim Chronosphere
 You should use an effective method of
contraception and talk to your doctor before
planning pregnancy. Epilim Chronosphere 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, including heart
 Defects of the lining of the spinal cord
 An abnormality of the spinal cord called „Spina bifida‟
 Malformations of the urethra
Women who take Epilim Chronosphere 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 Chronosphere 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
Chronosphere 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
Chronosphere if you want to become pregnant. Do not stop
taking Epilim Chronosphere 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 Chronosphere, 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 Epilim Chronosphere 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
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.

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