1. What is Zebinix and what is it used for

Zebinix contains the active substance eslicarbazepine acetate.

Zebinix belongs to a group of medicines called antiepileptics, used to treat epilepsy, a condition where the person has repeated seizures or fits.

Zebinix is used:

• as the only medicine (monotherapy) in adults with newly diagnosed epilepsy;
• with other antiepileptic medicines (adjunctive therapy) in adults, adolescents and children over 6 years of age who have epileptic seizures (fits) that affect only a part of the brain (partial seizures). These seizures may or may not be followed by a seizure that affects the whole brain (secondary generalisation).

Your doctor has prescribed Zebinix to reduce the number of seizures you have.

2. What you need to know before you take Zebinix

Do not take Zebinix:

• if you are allergic to eslicarbazepine acetate, to other carbamazepine-related compounds (e.g. carbamazepine or oxcarbazepine, medicines used to treat epilepsy), or to any of the other ingredients of this medicine (listed in section 6);
• if you have a certain type of heart rhythm disorder (second or third degree atrioventricular (AV) block).

Warnings and precautions

Talk to your doctor or pharmacist before you start taking Zebinix.

Tell your doctor immediately:

• if you have blisters or peeling of the skin and/or mucous membranes, rash, problems with swallowing or breathing, swelling of the lips, face, eyelids, throat or tongue. These could be signs of an allergic reaction;
• if you have confusion, worsening of seizures or decreased consciousness, which could be signs of low blood levels of salts.

Tell your doctor:

• if you have kidney problems. Your doctor may need to adjust the dose. Zebinix is not recommended in patients with severe kidney disease;
• if you have liver problems. Zebinix is not recommended in patients with severe liver problems;
• if you are taking any medicine that may cause an abnormality in the ECG (electrocardiogram) called a prolonged PR interval. If you are not sure if the medicines you are taking may cause this effect, talk to your doctor;
• if you have any heart disease such as heart failure or heart attack, or have any heart rhythm disorder;
• if you have seizures that start with a widespread electrical discharge that affects both sides of the brain.

A small number of people taking antiepileptics have had thoughts of harming themselves or suicide. If this happens while you are taking Zebinix, contact your doctor immediately.

Zebinix may make you feel dizzy and/or drowsy, particularly at the start of treatment. Be extra careful while taking Zebinix to avoid accidental injury, such as falls.

Be extra careful with Zebinix.

In post-marketing experience, in patients treated with Zebinix, serious and potentially life-threatening skin reactions have been reported, including Stevens-Johnson Syndrome/toxic epidermal necrolysis, drug reaction with eosinophilia and systemic symptoms (DRESS).

If you develop a severe rash or other skin symptom (see section 4), stop taking Zebinix and contact your doctor or seek medical attention immediately.

In patients of Thai and Chinese Han ethnic origin, the risk of serious skin reactions associated with carbamazepine or chemically-related compounds can be predicted by a blood test. Your doctor will be able to advise you on the need for such a blood test before taking Zebinix.

Children

Zebinix must not be given to children under 6 years of age.

Taking Zebinix with other medicines

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. This is because some medicines may affect the way Zebinix works, or Zebinix may affect the way other medicines work. Tell your doctor if you are taking:

• phenytoin (a medicine used to treat epilepsy), as you may need to have your dose adjusted;
• carbamazepine (a medicine used to treat epilepsy), as you may need to have your dose adjusted, and the following side effects of Zebinix may occur more frequently: double vision, abnormal coordination and dizziness;
• hormonal contraceptives (such as the pill) as Zebinix may reduce their effectiveness;
• simvastatin (a medicine used to lower cholesterol levels), as you may need to have your dose adjusted;
• rosuvastatin, a medicine used to lower cholesterol levels;
• the anticoagulant warfarin;
• monoamine oxidase inhibitor (MAOI) antidepressants;
• do not take oxcarbazepine (a medicine used to treat epilepsy) with Zebinix, as it is not known if it is safe to take these two medicines together.

See the section “Pregnancy and breast-feeding” for advice on contraception.

Pregnancy and breast-feeding

Zebinix should not be used if you are pregnant, as the effects of Zebinix on pregnancy and the unborn child are not known.

If you are planning to become pregnant, talk to your doctor before stopping your contraceptive and before becoming pregnant. Your doctor may decide to change your treatment.

There is limited data on the use of eslicarbazepine acetate in pregnant women.

Studies have shown an increased risk of congenital malformations and neurodevelopmental problems (brain development) in the children of women who take antiepileptic medicines, particularly when more than one antiepileptic medicine is taken at the same time.

If you are pregnant or think you may be pregnant, tell your doctor immediately. Do not stop taking your medicine until you have talked to your doctor. Stopping your medicine suddenly may cause seizures, which could be harmful for you and your unborn child. Your doctor may decide to change your treatment.

If you are a woman of childbearing age and not planning to become pregnant, you must use an effective method of contraception during treatment with Zebinix. Zebinix may affect the way hormonal contraceptives work, making them less effective in preventing pregnancy. Therefore, you are advised to use other forms of safe and effective contraception while taking Zebinix. Talk to your doctor, who will discuss with you the most suitable type of contraception to use while taking Zebinix. If you stop taking Zebinix, you should continue to use an effective method of contraception until the end of your current menstrual cycle. If you take Zebinix during pregnancy, your baby is also at risk of having bleeding problems immediately after birth. Your doctor may give you and your baby a medicine to prevent this.

Do not breast-feed while you are taking Zebinix. It is not known if Zebinix passes into breast milk.

Driving and using machines

Zebinix may cause dizziness, drowsiness and affect your vision, particularly at the start of treatment. If this happens to you, do not drive or use any tools or machines.

3. How to take Zebinix

Always take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.

400 mg once a day for one or two weeks, before increasing to the maintenance dose. Your doctor will decide whether you should be given this dose for one or two weeks.

Maintenance dose

The usual maintenance dose is 800 mg once a day.

Depending on how you respond to Zebinix, the dose may be increased to 1,200 mg once a day. If you are taking Zebinix alone (monotherapy), your doctor may consider increasing your dose to 1,600 mg once a day.

Patient with kidney problems

If you have kidney problems, you will usually be given a lower dose of Zebinix. Your doctor will decide on the correct dose for you. Zebinix is not recommended if you have severe kidney problems.

Elderly patients (over 65 years of age)

If you are an elderly patient and are taking Zebinix alone (monotherapy), the dose of 1,600 mg is not suitable for you.

Children over 6 years of age

Form and route of administration

Zebinix is taken by mouth. Swallow the tablet with a glass of water.

Zebinix can be taken with or without food.

If you have difficulty swallowing the tablet whole, you can crush it and add it to a small amount of water or apple sauce to take immediately.

The tablet can be divided into equal doses.

If you take more Zebinix than you should

If you accidentally take more Zebinix than you should, you are at risk of having more seizures; or you may feel that your heart is beating irregularly or faster. Contact your doctor or go immediately to a hospital if you experience any of these symptoms. Take the medicine pack with you, so that the doctor knows what you have taken.

If you forget to take Zebinix

If you forget to take a tablet, take it as soon as you remember and then continue as normal. Do not take a double dose to make up for a forgotten dose.

If you stop taking Zebinix

Do not stop taking Zebinix suddenly. If you do, you may have more seizures. Your doctor will decide for how long you should take Zebinix. If your doctor decides to stop your treatment with Zebinix, your dose will usually be reduced gradually. It is important that you complete the treatment as instructed by your doctor; otherwise, your symptoms may get worse.

If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
