This medication contains the active ingredient eslicarbazepine acetate.

This medication belongs to a group of medications called antiepileptics, used to treat epilepsy, a disease where the affected person has seizures or repeated convulsive crises.

This medication is used:

- as a single medication (monotherapy) in adult patients with newly diagnosed epilepsy,

- in combination with other antiepileptic medications (adjunctive therapy) in adult, adolescent, and children over 6 years old who suffer from epileptic seizures (convulsions) affecting a part of the brain (partial seizures). These seizures may be followed or not by a seizure affecting the entire brain (secondary generalization).

Your doctor has prescribed this medication to reduce the number of seizures.

Do not take Zekilep:

- if you are allergic to eslicarbazepine acetate, other carboxamide derivatives (such as carbamazepine or oxcarbazepine, medications used to treat epilepsy), or any of the other components of this medication (listed in section 6),

- if you have a certain type of heart rhythm disorder (second- or third-degree atrioventricular (AV) block).

Warnings and precautions

Consult your doctor or pharmacist before starting this medication.

Inform your doctor immediately:

- if you experience blisters or peeling of the skin and/or mucous membranes, rash, difficulty swallowing or breathing, swelling of the lips, face, eyelids, throat, or tongue. These may be signs of an allergic reaction,

- if you experience confusion, worsening seizures, or decreased consciousness, which may be signs of low blood levels of salts.

Inform your doctor:

- if you have kidney problems. Your doctor may need to adjust the dose. This medication is not recommended for patients with severe kidney disease,

- if you have liver problems. This medication is not recommended for patients with severe liver disease,

- if you are taking any medication that can cause an ECG (electrocardiogram) anomaly called prolonged PR interval. If you are unsure whether the medications you are taking can cause this effect, discuss it with your doctor,

- if you have any heart disease, such as heart failure or myocardial infarction, or have any heart rhythm alterations,

- if you have seizures that begin with a generalized electrical discharge affecting both sides of the brain.

A small number of people taking antiepileptic medications have had thoughts of self-harm or suicide. If this occurs while taking this medication, contact your doctor immediately.

This medication may cause dizziness and/or disorientation, particularly at the beginning of treatment. Be extra cautious while taking this medication to avoid accidental injuries, such as falls.

Be extra cautious with Zekilep

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

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

In patients of Thai origin and Chinese Han ethnic group, the risk of severe skin reactions associated with carbamazepine or chemically related compounds may be predicted by blood analysis of these patients. Your doctor will advise on the need for this blood test before taking this medication.

Children

This medication should not be administered to children under 6 years old.

Taking Zekilep with other medications

Inform your doctor or pharmacist if you are taking, have taken recently, or may need to take any other medication. This recommendation is in case any of them interfere with the way this medication works, or if this medication interferes with the effect of such medications. Inform your doctor if you are taking:

- phenytoin (a medication used to treat epilepsy), as you may need to adjust the dose,

- carbamazepine (a medication used to treat epilepsy), as you may need to adjust the dose, and the following side effects of this medication may occur more frequently: double vision, abnormal coordination, and dizziness,

- hormonal contraceptives (such as the birth control pill) as Zekilep may reduce the effectiveness of these,

- simvastatin (a medication used to reduce cholesterol levels), as you may need to adjust the dose,

- rosuvastatin, a medication used to reduce cholesterol levels,

- the anticoagulant warfarin,

- monoamine oxidase inhibitors (MAOIs),

- do not take oxcarbazepine (a medication used to treat epilepsy) with this medication, as it is unknown whether it is safe to take these two medications together.

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

Pregnancy and breastfeeding

This medication is not recommended for use during pregnancy, as the effects of eslicarbazepine acetate on pregnancy and the fetus are unknown.

If you plan to become pregnant, discuss this with your doctor before stopping your contraceptive method 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.

Research has shown an increased risk of congenital defects and neurological development problems (brain development) in children of women taking antiepileptic medications, particularly when taking more than one antiepileptic medication at a time. If you think you may be pregnant, inform your doctor immediately. Do not stop taking your medication until you have discussed this with your doctor. Stopping your medication without consulting your doctor may cause seizures, which can be dangerous for you and your unborn child. Your doctor may decide to change your treatment.

If you are a fertile woman and do not plan to become pregnant, use an effective contraceptive method during treatment with eslicarbazepine acetate. Eslicarbazepine acetate may affect the functioning of hormonal contraceptives, such as the birth control pill, and make them less effective in preventing pregnancy. Therefore, it is recommended to use other safe and effective contraceptive methods while taking this medication. Discuss this with your doctor, who will discuss with you the type of contraceptive most suitable to use while taking eslicarbazepine acetate. If you stop treatment with eslicarbazepine acetate, continue using an effective contraceptive method until the end of the current menstrual cycle. If you take eslicarbazepine acetate during pregnancy, your baby may be at risk of bleeding problems immediately after birth. Your doctor may give you and your baby a medication to prevent this.

Do not breastfeed while taking eslicarbazepine acetate. It is unknown whether it passes into breast milk.

Driving and operating machinery

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