Sodium valproate (also known as Epilim®)

Key points about Epilim

Epilim is used to treat epilepsy, control some mood disorders such as bipolar disorder and prevent migraine headaches.
Epilim is also called sodium valproate.
Epilim can seriously harm your unborn baby. People of all genders who are taking Epilim and are sexually active need to use effective contraception to prevent an unplanned pregnancy.

Epilim is not suitable for people who could become pregnant, or father a child. However, in some cases it may be the only treatment option available, for example for epilepsy where other treatments have not worked.

If you do need to continue Epilim then you must be use reliable contraception, even if you are not currently sexually active. Your doctor or nurse can advise you about reliable contraception.

Note: All anti-seizure medicines in pregnancy have the potential to harm an unborn child but the risks are higher with some medicines, including Epilim, especially early in your pregnancy and at higher doses. If you have epilepsy, having seizures while you are pregnant can also harm your unborn child so it is important to keep taking your anti-seizure medication.

If you are planning a pregnancy

When you are taking Epilim it is extremely important to plan ahead if you want to become pregnant. You need to see your doctor 6 to 12 months before you would like to become pregnant so that you can reduce any risks to your baby.

If you are able to father children, speak with your doctor about the potential risks of taking Epilim during conception, and your options if you wish to start a family.

You and your doctor need to agree on a plan about how to manage your medicines and your dose.Don’t stop taking your medicine suddenly without talking to your doctor first.

If you are pregnant or think you might be pregnant

Keep taking your medicine at the right dose, and contact your doctor, tell them you think you are pregnant and get an urgent appointment to see them.

Your doctor will start you on a low dose and increase your dose slowly over a few weeks.
It is usually taken 2 or 3 times a day.

Epilim is best taken with food. Take your doses at the same times each day, to help you to remember to take it.

Formulation	How to take it
Epilim liquid	Measure the right amount using an oral syringe or medicine spoon. You can get these from your pharmacy. Do not use a kitchen spoon as it will not give you the right amount. Read more: Tips on how to give medicines to babies and children.
Epilim tablets (white tablets)	You can swallow these tablets with a glass of water, juice or milk, or you can crush them to make it easier to swallow. Crush the tablets and mix with a small amount of soft food such as yoghurt or a small drink. Swallow the food or drink straight away.
Epilim EC tablets (lilac tablets)	These are called enteric-coated (EC) tablets and are designed to prevent the medicine from upsetting the stomach. Do not crush or chew them, as this will destroy the coating and be more likely to cause side effects. Take these tablets with a glass of water, juice or milk.

Missed dose: If you forget to take your dose, take it as soon as you remember that day. But, if it is nearly time for your next dose, just take the next dose at the right time. Do not take double the dose.
Keep taking Epilim regularly every day (see tips to help you remember to take your medicines regularly). It may take a few weeks before you experience the full benefits of Epilim. Do not stop taking Epilim suddenly as this can cause problems; speak to your doctor or nurse before stopping.
Epilim may interact with some other medicines and herbal supplements, so check with your doctor or pharmacist before starting Epilim or before starting any new medicines. Do not take indigestion medication (antacids) within 2 hours of taking Epilim.
