• you know that there is a genetic problem caused by a mitochondrial disorder in your family.
If you are not sure if any of the above apply to you, talk to your doctor or pharmacist before taking Sodium Valproate Tablets.
Weight gain
Taking Sodium Valproate Tablets 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 Sodium Valproate Tablets and during your treatment.
Other medicines and Sodium Valproate Tablets
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 Sodium Valproate Tablets can affect the way some other medicines work. Also some medicines can affect the way Sodium Valproate Tablets work.
The following medicines can increase the chance of you getting side effects, when taken with Sodium Valproate Tablets:
• Some medicines used for pain and inflammation (salicylates) such as aspirin
• Some other medicines used to treat fits (epilepsy) -see Section 3: “Patients taking other medicines for ‘fits.'” This includes medicines such as phenobarbital, primidone, phenytoin, carbamazepine, topiramate, lamotrigine and felbamate
Sodium Valproate Tablets 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 Sodium Valproate Tablets work:
• 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 Sodium Valproate Tablets and carbapenems should be avoided because
it may decrease the effect of your medicine.
• Colestyramine used to lower blood fat (cholesterol) levels.
Taking Sodium Valproate Tablets with food, drink and alcohol
Alcohol intake is not recommended during treatment.
Pregnancy and breast feeding and fertility IMPORTANT ADVICE FOR WOMEN
• Valproate can be harmful to unborn children when taken by a woman during pregnancy.
• Valproate carries a risk if taken during pregnancy.
The higher the dose, the higher the risks but all doses carry a risk.
• It can cause serious birth defects and can affect the way in which the child develops as it grows. Birth defects which have been reported include spina bifida (where the bones of the spine are not properly developed); facial and skull malformations; heart, kidney, urinary tract and sexual organ malformations; limb defects.
• If you take valproate during pregnancy you have a higher risk than other women of having a child with birth defects that require medical treatment. Because valproate has been used for many years we know that in women who take valproate around 10 babies in every 100 will have birth defects. This compares to 2-3 babies in every 100 born to women who don't have epilepsy.
• It is estimated that up to 30-40% of preschool children whose mothers took valproate during pregnancy may have problems with early childhood development. Children affected can be slow to walk and talk, intellectually less able than other children, and have difficulty with language and memory.
• Autistic spectrum disorders are more often diagnosed in children exposed to valproate and there is some evidence children may be more likely to develop symptoms of Attention Deficit Hyperactivity Disorder (ADHD).
• If you are a woman capable of becoming pregnant your doctor should only prescribe valproate for you if nothing else works for you.
• Before prescribing this medicine to you, your doctor will have explained what might happen to your baby if you become pregnant whilst taking valproate. If you decide later you want to have a child you should not stop taking your medicine until you have discussed this with your
doctor and agreed a plan for switching you onto another product if this is possible.
• Ask your doctor about taking folic acid when trying for a baby. Folic acid can lower the general risk of spina bifida and early miscarriage that exists with all pregnancies. However, it is unlikely that it will reduce the risk of birth defects associated with valproate use.
FIRST PRESCRIPTION
If this is the first time you have been prescribed valproate your doctor will have explained the risks to an unborn child if you become pregnant. Once you are of childbearing age, you will need to make sure you use an effective method of contraception throughout your treatment. Talk to your doctor or family planning clinic if you need advice on contraception.
Key messages:
• Make sure you are using an effective method of contraception.
• Tell your doctor at once if you are pregnant or think you might be pregnant.
CONTINUING TREATMENT AND NOT TRYING FOR A BABY
If you are continuing treatment with valproate but you don't plan to have a baby make sure you are using an effective method of contraception. Talk to your doctor or family planning clinic if you need advice on contraception.
Key messages:
• Make sure you are using an effective method of contraception
• Tell your doctor at once if you are pregnant or think you might be pregnant.
CONTINUING TREATMENT AND CONSIDERING TRYING FOR A BABY
If you are continuing treatment with valproate and you are now thinking of trying for a baby you must not stop taking either your valproate or your contraceptive medicine until you have discussed this with your prescriber. You should talk to your doctor well before you become pregnant so that you can put several actions in place so that your pregnancy goes as smoothly as possible and any risks to you and your unborn child are reduced as much as possible.
Your doctor may decide to change the dose of valproate or switch you to another medicine before you start trying for a baby.
If you do become pregnant you will be monitored very closely both for the management of your underlying condition and to check how your unborn child is developing.
Ask your doctor about taking folic acid when trying for a baby. Folic acid can lower the general risk of spina bifida and early miscarriage that exists with all pregnancies. However, it is unlikely that it will reduce the risk of birth defects associated with valproate use.
Key messages:
• Do not stop using your contraception before you have talked to your doctor and worked together on a plan to ensure your epilepsy is controlled and the risks to your baby are reduced.
• Tell your doctor at once when you know or think you might be pregnant.
UNPLANNED PREGNANCY WHILST CONTINUING TREATMENT
Babies born to mothers who have been on valproate are at serious risk of birth defects and problems with development which can be seriously debilitating. If you are taking valproate and you think you are pregnant or might be pregnant contact your doctor at once. Do not stop taking your medicine until your doctor tells you to.
Ask your doctor about taking folic acid. Folic acid can lower the general risk of spina bifida and early miscarriage that exists with all pregnancies.
However, it is unlikely that it will reduce the risk of birth defects associated with valproate use.
Key messages:
• Tell your doctor at once if you know you are pregnant or think you might be pregnant.
• Do not stop taking valproate unless your doctor tells you to.
Make sure you read the patient booklet and sign the Acknowledgement of Risk form which should be given to you and discussed with you by your doctor or pharmacist.

You may feel sleepy when taking Sodium Valproate Tablets. 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 health problems may increase sleepiness.

Stopping Sodium Valproate Tablets
Keep taking Sodium Valproate Tablets until your doctor tells you to stop. If your doctor advises you to stop taking Sodium Valproate Tablets, (perhaps in order to start another medicine for your epilepsy) this will be done gradually to maintain control of your fits. Do not stop taking Sodium Valproate Tablets without talking to your doctor first and never suddenly stop taking your Sodium Valproate Tablets if you are pregnant since this may result in fits which may harm you or your unborn child.

Make sure you or your child keep your regular appointments
for a check-up. They are very important as your or your child's dose may need to be changed. Sodium Valproate Tablets can change the levels of liver enzymes shown up in blood tests. This can mean that your or your child's liver is not working properly. If you or your child go into hospital or visit another doctor or a dentist, tell them you are taking Sodium Valproate Tablets.
If you have any further questions on the use of this product, ask your doctor or pharmacist.
4. POSSIBLE SIDE EFFECTS
