Children and adolescents

Children and adolescents under 18 years of age: Episenta should not be used in children and adolescents under 18 years of age for the treatment of mania.

Other medicines and Episenta

Tell your doctor, pharmacist or nurse if you are taking, have recently taken or might take any other medicines. This includes medicines you buy without a prescription, including herbal medicines. This is because Episenta can affect the way some other medicines work. Also some medicines can affect the way Episenta works.

The following medicines can increase the chance of you getting side effects, when taken with Episenta:

• 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, rufinamide, topiramate, lamotrigine and felbamate.
• acetazolamide used to treat glaucoma, edema or fits

Episenta 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 health problems (including schizophrenia, bipolar disorder and depression) such as quetiapine, diazepam and olanzapine
• nimodipine
• propofol – used for anaesthesia

The following medicines can affect the way Episenta works:

• oestrogen-containing products (including some birth control pills)
• some medicines used for the prevention and treatment of malaria such as mefloquine and chloroquine
• cimetidine used for stomach ulcers
• protease inhibitors such as lopinavir and ritonavir – used for HIV infection and AIDS
• antibiotics e.g. erythromycin, carbapenem agents (antibiotics used to treat bacterial infections). The combination of valproic acid and carbapenems should be avoided because it may decrease the effect of sodium valproate.
• rifampicin used to treat tuberculosis and other infections
• cholestyramine used to lower blood fat (cholesterol) levels

It may still be possible for you to take Episenta; your doctor will advise you on what is suitable for you.

The risks of valproate when taken during pregnancy (irrespective of the disease for which valproate is used)

• Talk to your doctor immediately if you are planning to have a baby or are pregnant.
• 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. Hearing problems or deafness have been reported in children exposed to valproate during pregnancy.
• 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 to 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 during pregnancy, and there is some evidence that children exposed to valproate during pregnancy are at increased risk of developing Attention Deficit Hyperactivity Disorder (ADHD).
• 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 baby you must not stop taking your medicine or your method of contraception until you have discussed this with your doctor.
• If you are a parent or a caregiver of a female child treated with valproate, you should contact the doctor once your child using valproate experiences their first period (menarche).
• 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.

Please choose and read the situations which apply to you from the situations described below:

If this is the first time you have been prescribed Episenta your doctor will have explained the risks to an unborn child if you become pregnant.

I AM TAKING EPISENTA AND PLANNING TO HAVE A BABY

If you are planning to have a baby, first schedule an appointment with your doctor.

Do not stop taking Episenta or your contraception, until you have discussed this with your doctor. Your doctor will advise you further.

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. Your doctor will refer you to a specialist experienced in the management of bipolar disorder or epilepsy, so that alternative treatment options can be evaluated early on. Your specialist 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 specialist may decide to change the dose of Episenta or switch you to another medicine, or stop treatment with Episenta, a long time before you become pregnant – this is to make sure your illness is stable.

Ask your doctor about taking folic acid when planning to have 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 taking Episenta unless your doctor tells you to.
• Do not stop using your methods of birth control (contraception) before you have talked to your doctor and worked together on a plan to ensure your condition is controlled and the risks to your baby are reduced.

• Schedule an urgent appointment with your doctor if you are pregnant or think you might be pregnant.

I AM PREGNANT AND I AM USING EPISENTA

Do not stop taking Episenta, unless your doctor tells you to as your condition may become worse.

Schedule an urgent appointment with your doctor if you are pregnant or think you might be pregnant.

Your doctor will advise you further.

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.

You will be referred to a specialist experienced in the management of bipolar disorder or epilepsy, so that alternative treatment options can be evaluated.

In the exceptional circumstances when Episenta is the only available treatment option during pregnancy, you will be monitored very closely both for the management of your underlying condition and to check how your unborn child is developing. You and your partner could receive counselling and support regarding the valproate exposed pregnancy.

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:

• Schedule an urgent appointment with your doctor if you are pregnant or think you might be pregnant.
• Do not stop taking Episenta unless your doctor tells you to.
• Make sure you are referred to a specialist experienced in the treatment of epilepsy or bipolar disorder to evaluate the need for alternative treatment options.
• You must get thorough counselling on the risks of Episenta during pregnancy, including teratogenicity and developmental effects in children.
• Make sure you are referred to a specialist for prenatal monitoring in order to detect possible occurrences of malformations.

Make sure you read the patient guide that you will receive from your doctor. Your doctor will discuss the Annual Risk Acknowledgement Form and will ask you to sign it and keep it. You will also receive a Patient Card from your pharmacist to remind you of valproate risks in pregnancy.

Breast-feeding

A small amount of sodium valproate, the active substance of Episenta, gets into the breast milk. Talk to your doctor about whether you should breast-feed your baby.

Fertility

Episenta may decrease your fertility. However, single reports have shown that this effect is reversible after discontinuation of the medicine.

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.

Episenta 1000 mg: This medicine contains 137.9 mg sodium (main component of cooking/table salt) in each dose. This is equivalent to 7 % of the recommended maximum daily dietary intake of sodium for an adult.

Patients with kidney problems

Patients taking other medicines for fits (epilepsy)

You or your child may be taking other medicines for epilepsy at the same time as Episenta. If so, your doctor should gradually initiate treatment depending on your or your child’s condition. Your doctor may increase the dose of Episenta by 5–10 mg for each kg of body weight each day depending on which other medicines you are taking.

If you take more Episenta than you should

If you take more Episenta 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 sachets with you.

If you forget to take 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. Do not take a double dose to make up for a forgotten dose.

If you stop taking Episenta

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.

Tests

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. Episenta 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 Episenta.
