1. What Eslicarbazepina Normon is and what it is used for

Eslicarbazepina Normon contains the active substance eslicarbazepine acetate.

Eslicarbazepine belongs to a group of medicines called antiepileptics, used to treat epilepsy, a condition in which affected individuals experience repeated seizures or convulsive fits.

Eslicarbazepine is used:

• As a single medication (monotherapy) in adult patients with newly diagnosed epilepsy.
• In combination with other antiepileptic medicines (adjunctive therapy) in adult, adolescent, and children over 6 years of age who experience epileptic seizures (convulsions) affecting one part of the brain (partial seizures). These seizures may or may not be followed by a seizure affecting the entire brain (secondary generalization).

Your doctor has prescribed eslicarbazepine to reduce the number of seizures.

2. What you need to know before taking Eslicarbazepine Normon

Do not take Eslicarbazepine Normon:

• If you are allergic to eslicarbazepine acetate, to other carboxamide derivatives (for example, carbamazepine or oxcarbazepine, medicines used to treat epilepsy), or to any of the other components 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 starting this medicine.

Tell your doctor immediately:

• If you develop blisters or peeling of the skin and/or mucous membranes, rash, difficulty swallowing or breathing, or swelling of the lips, face, eyelids, throat, or tongue. These could be signs of an allergic reaction.
• If you experience confusion, worsening of seizures, or decreased level of 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 your dose. Eslicarbazepine is not recommended in patients with severe renal impairment.
• If you have liver problems. Eslicarbazepine is not recommended in patients with severe hepatic impairment.
• If you are taking any medicine that may cause an abnormality in the ECG (electrocardiogram) known as PR interval prolongation. If you are unsure whether your medicines may cause this effect, discuss it with your doctor.
• If you have any heart disease such as heart failure or heart attack, or any heart rhythm disorder.
• If you have seizures that begin with a generalized electrical discharge affecting both sides of the brain.

A small number of people taking antiepileptic medicines have had suicidal thoughts or thoughts of self-harm. If this happens to you while taking eslicarbazepine, contact your doctor immediately.

Eslicarbazepine may cause dizziness and/or drowsiness, especially at the beginning of treatment. Take special care while taking eslicarbazepine to avoid accidental injury, such as falls.

Take special care with eslicarbazepine

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

If you develop a severe rash or other skin symptoms (see section 4), stop taking eslicarbazepine and consult your doctor or seek immediate medical attention.

In Thai patients and Han Chinese ethnic groups, the risk of severe skin reactions associated with carbamazepine or chemically related compounds can be predicted by a blood test. Your doctor may advise you on whether such a blood test is necessary before starting eslicarbazepine.

Children

Eslicarbazepine must not be given to children aged 6 years or younger.

Other medicines and Eslicarbazepine Normon

Tell your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicines. This is important because some medicines may interfere with how eslicarbazepine works, or eslicarbazepine may interfere with the effect of other medicines. Inform your doctor if you are taking:

• Phenytoin (a medicine used to treat epilepsy), as your dose may need to be adjusted.
• Carbamazepine (a medicine used to treat epilepsy), as your dose may need to be adjusted, and the following side effects of eslicarbazepine may occur more frequently: double vision, abnormal coordination, and dizziness.
• Hormonal contraceptives (such as the contraceptive pill), as eslicarbazepine may reduce their effectiveness.
• Simvastatin (a medicine used to lower cholesterol levels), as your dose may need to be 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) together with eslicarbazepine, as it is unknown whether it is safe to take these two medicines together.

See the section “Pregnancy and breastfeeding” for recommendations regarding contraception.

Pregnancy and breastfeeding

Eslicarbazepine is not recommended during pregnancy, as the effects of eslicarbazepine on pregnancy and the unborn child are unknown.

If you are planning a pregnancy, speak with your doctor before stopping contraception 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 neurological developmental problems (brain development) in children of women taking 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, inform your doctor immediately. You must not stop taking your medicine without first discussing it with your doctor. Stopping your medication without medical advice may cause seizures, which could be dangerous for you and your unborn child. Your doctor may decide to change your treatment.

If you are a woman of childbearing potential and are not planning to become pregnant, you should use an effective method of contraception during treatment with eslicarbazepine. Eslicarbazepine may affect the effectiveness of hormonal contraceptives, such as the contraceptive pill, making them less effective in preventing pregnancy. Therefore, you are advised to use other safe and effective forms of contraception while taking eslicarbazepine. Talk to your doctor, who will discuss with you the most appropriate type of contraception to use while taking eslicarbazepine. If treatment with eslicarbazepine is stopped, you should continue using an effective method of contraception until the end of the current menstrual cycle. If you take eslicarbazepine during pregnancy, your baby may also be at risk of bleeding problems immediately after birth. Your doctor may give you and your baby a medicine to prevent this.

Do not breast-feed while taking eslicarbazepine. It is unknown whether eslicarbazepine passes into breast milk.

Driving and using machines

Eslicarbazepine may cause dizziness, drowsiness, and affect your vision, particularly at the beginning of treatment. If this occurs, do not drive or operate tools or machinery.

Eslicarbazepine Normon contains sodium

This medicine contains less than 23 mg of sodium (1 mmol) per tablet; this is essentially “sodium-free”.

Maintenance dose

The usual maintenance dose is 800 mg once daily.

Depending on your response to eslicarbazepine, the dose may be increased to 1,200 mg once daily. If you are taking eslicarbazepine alone (monotherapy), your doctor may consider increasing your dose to 1,600 mg once daily.

Patients with renal problems

If you have kidney problems, you will generally be given a lower dose of eslicarbazepine. Your doctor will determine the correct dose for you. Eslicarbazepine is not recommended if you have severe kidney problems.

Elderly patients (over 65 years of age)

If you are elderly and are taking eslicarbazepine as monotherapy, the 1,600 mg dose is not suitable for you.

Children over 6 years of age

Starting dose

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

Maintenance dose

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

Children ≥ 60 kg

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

Method and route of administration

Eslicarbazepine is administered orally. Swallow the tablet with a glass of water.

Eslicarbazepine may be taken with or without food.

If you have difficulty swallowing the whole tablet, you may crush it and mix it with a small amount of water or apple sauce, and take it immediately.

The tablet may be divided into equal doses.

If you take more Eslicarbazepine Normon than you should

If you accidentally take more eslicarbazepine than prescribed, you may be at risk of having more seizures; or you may feel that your heartbeat is irregular or faster. Contact your doctor or go immediately to a hospital if you experience any of these symptoms. Take the medicine packaging with you so the doctor knows what you have taken.

In case of overdose or accidental ingestion, contact your doctor or pharmacist immediately or call the Toxicology Information Service at telephone number 91 562 04 20, indicating the medicine and the amount ingested.

If you forget to take Eslicarbazepine Normon

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

If you stop taking Eslicarbazepine Normon

Do not suddenly stop taking the tablets. If you do, you may be at risk of having more seizures. Your doctor will decide for how long you should take eslicarbazepine. If your doctor decides to discontinue treatment with eslicarbazepine, your dose will usually be gradually reduced. It is important that you complete the treatment as instructed by your doctor; otherwise, your symptoms may worsen.

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