What Epilim Chronosphere is
The name of your medicine is Epilim Chronosphere 1000mg
Prolonged Release Granules (called Epilim Chronosphere in this
leaflet). “Prolonged release” means that the active ingredients
(sodium valproate and valproic acid) are slowly released from the
granules over a long period of time.
Epilim Chronosphere Prolonged Release Granules are also
available in strengths 100mg, 250mg, 500mg and 750mg.
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

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
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.
Check with your doctor or pharmacist before taking your
medicine if:
• You have diabetes. This medicine may affect the results of urine
• You have kidney problems. Your doctor may give you a lower
• 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 Chronosphere
Weight gain
Taking Epilim Chronosphere 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 Chronosphere and during your treatment.

• 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
• Unplanned pregnancy is not desirable in women taking Epilim
• 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)
The following medicines can increase the chance of you
• Deformities of the bones, including hip dislocation
getting side effects, when taken with Epilim Chronosphere:
• Malformations of the arms and legs
• Some medicines used for pain and inflammation (salicylates)
• Deformities of the tube from the bladder to the penis, where the

Taking Epilim Chronosphere with other
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.

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)
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.

changes to your treatment or dose

urgent medical treatment:

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.

the skin or whites of the eyes), loss of appetite, swelling

immediately if you have these symptoms
• You have a skin rash or skin lesions with a pink/red ring and a

bruising or bleeding for no reason
