What Episenta is and what it is used for
FOR Episenta contains the active ingredient sodium valproate, which belongs to a group of medicines called antiepileptics which are used to control epileptic seizures.
Episenta is used to treat various types of epilepsy (seizures).
Before you take Episenta
Do NOT take Episenta capsules if:
- you are allergic (hypersensitive) to sodium valproate or any of the other ingredients of the capsules (listed in Section 6 Further Information)
- you, or a member of your family, have or have had severe liver problems
- you suffer from a disease called porphyria (a rare condition that affects the breakdown of components of red blood cells)
Before you take Episenta tell your doctor if:
- you have systemic lupus erythematous (an allergic condition which causes joint pain, skin rashes and fever)
- you have any metabolic disorders, particularly inherited enzyme deficiency disorders such as urea cycle disorder, because of a risk of an increased ammonia level in your blood
- you have reduced kidney function. Your doctor may want to monitor the levels of sodium valproate in your blood and change your dose as necessary
- you are pregnant, think you might be, or are planning to become pregnant
- you are a woman of childbearing age. You should be informed of the risks and benefits of treatment with Episenta in pregnancy
- you are breast feeding
- you are being tested for diabetes, as Episenta may affect the results of urine tests.

Take special care with Episenta Capsules
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.
It is very important that you tell your doctor before you take Episenta if you are pregnant or are planning to become pregnant.
Tell your doctor immediately if you become pregnant whilst taking Episenta.
Your doctor should discuss with you the problems that may arise if Episenta is used in pregnancy because of the potential risk to the foetus.
Women who are receiving treatment for epilepsy are 2 to 3 times more likely to have babies with deformities than in the general population. The deformities most frequently seen are cleft palate and heart or blood vessel defects. Developmental delay has also been reported in children born to mothers with epilepsy.
Women who take sodium valproate during the first months of pregnancy to control their epilepsy have a small risk (1 to 2%) of having a baby with spina bifida, an abnormality of the spinal cord. Taking folic acid 5mg daily 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 deformities in your baby. These can usually be detected in the first part of pregnancy by the routine antenatal screening tests. Some babies may develop less quickly than normal and rarely, some may have blood clotting problems if the mother has taken sodium valproate during pregnancy.
If treatment with Episenta is considered necessary, the lowest effective dose will be used, which may be given as several small doses during the day. During pregnancy, specialised prenatal monitoring should be given to detect any deformities.
It is important, however, not to stop Episenta suddenly as this may result in seizures, which may harm you or your unborn baby.
Driving and using machines:
You may experience drowsiness when you first start taking Episenta, or if you are taking it with other medicines, such as other antiepileptic drugs or benzodiazepines. If affected you should not drive or operate machinery.
How to take Episenta
Always take Episenta capsules exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure.
Your doctor will decide the number of capsules you should take. This will depend on your age and weight and will be adjusted to achieve adequate control of your seizures.
The daily dosage may be taken as one single or two divided doses (half in the morning and half in the evening).
Dose for adults including the elderly:
The usual starting dose is 600mg daily increasing by 150 – 300mg every three days until the seizures are controlled.
This dose is usually within the range of “1000 mg to 2000mg daily, but can be increased to a maximum of 2500mg daily if necessary. Your doctor may alter your dose if you are taking other antiepileptic drugs, have poor kidney function or you are an elderly patient.
Dose for children:
The dose for children will depend on their weight:
For children over 20kg the usual starting dose is 300mg daily. This can be increased up to a maximum of 35mg for each kg of bodyweight to control the seizures.
For children under 20kg the usual dose is 20mg for each kg of bodyweight which can be increase up to a maximum of 40mg for each kg of bodyweight daily.
Do not stop taking Episenta without consulting your doctor. If you stop, your seizures may return. You should continue to take Episenta for as long as your doctor tells you to.
How to take Episenta:
The capsules should be swallowed whole without chewing with plenty of liquid, e.g. a full glass of water.
If you have difficulty in swallowing, the contents of the capsule may be sprinkled or stirred into soft food or drinks and swallowed immediately without chewing or crushing the granules. The food or drink should be cold or at room temperature. A mixture of the granules with liquid or soft food should not be stored for future use. If the granules are taken in a drink, some may stick to the glass after the drink has been finished, you should rinse the glass with a small amount of water and drink this as well.
The granules should not be given in babies’ bottles as they can block the teat.
If you take more Episenta capsules than you should or if someone else accidentally takes your medicine contact your nearest casualty department or tell your doctor or pharmacist immediately. Remember to take the pack, this leaflet and any remaining capsules with you.
If you forget to take a dose of Episenta:
Take it as soon as you remember. If your next dose is due within 2 hours, take a single dose now and do not take the next dose. Never double up the next dose to make up for the one missed.
