What Epilim IV is used for

Epilim IV is a medicine used to for the treatment of epilepsy in adults and children.

Epilepsy is a condition where you have repeated seizures (fits). There are many different types of seizures, ranging from mild to severe.

Epilim IV belongs to a group of medicines called anticonvulsants.

These medicines are thought to work by controlling brain chemicals which send signals to nerves so that seizures do not happen.

Epilim IV may also be used to control mania, a mental condition with episodes of overactivity, elation or irritability.

Epilim IV may be used alone or in combination with other medicines to treat your condition.

Epilim IV may be used short-term in place of oral Epilim tablets or liquid when the medicine cannot be given by mouth.

Your doctor, however, may have prescribed Epilim IV for another reason.

Ask your doctor if you have any questions about why it has been prescribed for you.

There is no evidence that Epilim IV is addictive.

This medicine is available only with a doctor's prescription.

How it is given

Epilim IV will be given to you as an infusion or injection into the veins.


If you are currently taking an oral formulation of Epilim (tablets, liquid or syrup) and are now changing over to Epilim IV, the total daily dose of Epilim IV should remain the same. In these circumstances, Epilim IV may be given as several separate injections, drips or infusions throughout the day, or as one long continuous drip or infusion lasting 24 hours a day.

If you are not currently taking Epilim or any other form of sodium valproate by mouth, your doctor will decide what dose you will receive, depending on your condition and other factors such as your weight.


The dose for children is usually 20 to 30mg for each kg of body weight every day. If epilepsy is not controlled the dose may be increased up to 40mg for each kg of body weight every day, as long as blood tests are done to check the amount of Epilim IV in the blood. If higher doses are needed, further blood tests must be done to check that Epilim IV is not causing side effects.

If you take too much (overdose)

Your doctor will decide what dose of Epilim IV you need, and this will be given under close supervision, usually in a hospital setting.

The risk of an overdosage in these circumstances is low. In the event of an overdose occurring, your doctor will decide on the treatment necessary.

While you are receiving it

Be careful when driving or operating machinery until you know how Epilim IV affects you.

It may cause drowsiness in some people. Make sure you know how you react to Epilim IV before you drive a car, operate machinery or do anything else that could be dangerous if you are drowsy or light headed.

The effects of alcohol could be made worse while you are receiving Epilim IV.

Combining it and alcohol can make you more sleepy, dizzy or lightheaded. Your doctor may suggest you avoid alcohol while you are treated with Epilim IV.
