1. What Zebinix is and what it is 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 someone has repeated seizures or fits.

Zebinix is used:

  • on its own (monotherapy) in adult patients with newly diagnosed epilepsy
  • with other antiepileptic medicines (adjunctive therapy), in adult, adolescents and children patients above 6 years of age, whoare experiencing seizures that affect one part of the brain (partial seizure). These seizures may or may not be followed by a seizure affecting all of the brain (secondary generalisation).

Zebinix has been given to you by your doctor to reduce your number of seizures.

2. What you need to know before you take Zebinix

Do not take Zebinix:

  • if you are allergic to eslicarbazepine acetate, to other carboxamide derivatives (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 suffer from a certain type of heart rhythm disorder (second or third degree atrioventricular (AV) block).

Warnings and precautions

Talk to your doctor or pharmacist before taking Zebinix.

Contact your doctor immediately:

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

Please tell your doctor:

  • if you have kidney problems. Your doctor may need to adjust the dose. Zebinix is not recommended in patients with severe renal disease.
  • if you have liver problems. Zebinix is not recommended in patients with severe liver problems.
  • if you are taking any medicine which can cause an abnormality on the ECG (electrocardiogram) called increased PR interval. If you are not sure if the medicines you are taking could have this effect, discuss with your doctor.
  • if you suffer from a heart disease such as heart failure or heart attack, or have any heart rhytm disorder.
  • if you suffer from seizures that begin with a widespread electric discharge that involves both sides of the brain.

A small number of people being treated with antiepileptics have had thoughts of harming or killing themselves. If at any time you have these thoughts, when taking Zebinix, contact your doctor immediately.

Zebinix may make you feel dizzy and/or drowsy, particularly at the beginning of treatment. Take special care when taking Zebinix to avoid accidental injury, such as fall.

Take special care with Zebinix:

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

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

In patients of Han Chinese or Thai origin the risk of serious skin reactions associated with carbamazepine or chemically-related compounds may be predicted by testing a blood sample of these patients. Your doctor should be able to advise if a blood test is necessary before taking Zebinix.


Zebinix is not to be given to children aged 6 years and below.

Other medicines and Zebinix

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. This is just in case any of them interfere with how Zebinix works or how Zebinix interferes with their effect.

Tell your doctor if you are taking:

  • phenytoin (a medicine used to treat epilepsy) since your dose may need to be adjusted;
  • carbamazepine (a medicine used to treat epilepsy) since your dose may have to be adjusted and the following side effects of Zebinix may occur in higher frequency: seeing double, abnormal coordination and dizziness;
  • hormonal contraceptives (such as the contraceptive pill) since Zebinix may make these less effective;
  • simvastatin (a medicine used to lower cholesterol levels) since your dose may have to be adjusted;
  • rosuvastatin, a medicine used to lower cholesterol level;
  • the blood thinner - warfarin;
  • tricyclic antidepressants e.g. amitriptyline;
  • do not take oxcarbazepine (a medicine used to treat epilepsy) with Zebinix, as it is not known whether it is safe to take these medicines together.

See ‘Pregnancy and breast-feeding’ section for advice about contraception.

Pregnancy and breast-feeding

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

There are no data from the use of eslicarbazepine acetate in pregnant women. Research has shown an increased risk of birth defects in children of women taking antiepileptic medicines. On the other hand effective antiepileptic therapy must not be interrupted since the worsening of the disease is harmful to both the mother and the unborn child.

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

Zebinix may make hormonal contraceptives such as the contraceptive pill less effective. Therefore, it is recommended that you use other forms of safe and effective contraception, when taking Zebinix up to the end of the current menstrual cycle after stopping treatment.

Driving and using machines

Zebinix may make you feel dizzy, drowsy and affect your vision, particularly at the beginning of treatment. If this happens to you, do not drive or use any tools or machines.

Zebinix contains methyl parahydroxybenzoate (E218) and sulphites

Zebinix oral suspension contains methyl parahydroxybenzoate (E218) which may cause allergic reactions (possibly delayed) and sulphites which may rarely cause severe hypersensitivity reactions and bronchospasm.

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.


Dose when you start treatment

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

Maintenance dose

The usual maintenance dose is 800 mg once daily.

Depending on how you respond to Zebinix, your dose may be increased to 1,200 mg once daily. If you are taking Zebinix on its own your doctor may consider you can benefit of a dose of 1,600 mg once daily.

Patients with kidney problems

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

Elderly (over 65 years of age)

If you are elderly and taking Zebinix on its own the dose of 1,600 mg is not a suitable dose for you.

Children above 6 years of age

Dose when you start treatment

The starting dose is 10 mg per kg body weight taken once a day for one or two weeks, before increasing to the maintenance dose.

Maintenance dose

Depending on the response to Zebinix, the dose may be increased by 10 mg per kg body weight, at intervals of one or two weeks, up to 30 mg per kg body weight. The maximum dose is 1,200 mg once daily.

Children with ≥60 kg

Children with 60 kg or more body weight should take the same dose as adults.

Other form of this medicine, like oral suspension, maybe more suitable for children. Ask your doctor or pharmacist.

Method and route of administration

Zebinix is for oral use.

Zebinix oral suspension may be taken with or without food.

Shake well before use.

Always use the oral syringe provided to take your medicine.

Instructions for use:

Step 1. Remove the bottle, the oral syringe and the bottle adapter from the box

Step 2. Shake the bottle for at least 10 seconds and remove the child resistant closure by pushing it down and turning it counter-clockwise (to the left).

Step 3. Insert the bottle adapter in the bottle neck opening. You may need to apply some pressure to insert it securely. Once inserted, the bottle adapter must not be removed from the bottle. The bottle can be closed with the closure with the bottle adapter still in place.

Step 4. To ease the process you should mark the desired volume in the syringe by moving the plunger. Insert the tip of the oral syringe into the bottle adapter opening, keeping the bottle upright. Push the plunger all the way down. This will create pressure inside the bottle that will help the dosing of the suspension, forcing it to leave from the bottle to the oral syringe.

Step 5: Hold the oral syringe in place and turn the bottle upside down.

Gently pull the plunger of the oral syringe to the desired volume.

Step 6: If you see any air bubbles in the oral syringe, push the plunger upwards just far enough to completely push out any large air bubbles. Gently pull the plunger back downwards to the dose prescribed by your doctor.

Step 7. Turn the bottle upright and remove the entire oral syringe from the bottle. Be careful, do not push the plunger down when removing the oral syringe from the bottle.

Step 8. Replace the closure on the bottle by turning it clock-wise (to the right).

Step 9. Place the oral syringe into the mouth against the inside of the cheek. Press the plugger down slowly to release Zebinix into the mouth.

Step 10: Rinse the empty oral syringe after each use into a glass of clean water. Repeat this cleaning process 3 times.

Store the bottle and the oral syringe together in the carton until next use.

If you take more Zebinix than you should

If you accidently take more Zebinix than you should, you are potentially at risk of having more seizures; or you may feel like your heart beat is irregular or faster. Contact a doctor or go to a hospital immediately if you experience any of the above symptoms. Take the medicine pack with you. This is so the doctor knows what you have taken.

If you forget to take Zebinix

If you forget to take a dose, take it as soon as you remember and carry on as usual. Do not take a double dose to make up for a forgotten dose.

If you stop taking Zebinix

Do not stop taking your oral suspension suddenly. If you do, you are at risk of having more seizures. Your doctor will decide how long you should take Zebinix. Should your doctor decide to stop your treatment with Zebinix your dose will usually be reduced gradually. It is important that your treatment is completed as advised by your doctor or your symptoms may get worse.

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