1. What is Feoxan and what is it used for

Feoxan contains the active substance eslicarbazepine acetate.

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

Eslicarbazepine is used:

• as the only medicine (monotherapy) in adult patients with newly diagnosed epilepsy;
• in combination with other antiepileptic medicines (adjunctive therapy) in adult, adolescent, and child patients above 6 years of age who suffer from epileptic seizures (convulsions) that affect only a part of the brain (partial seizures). These seizures may or may not be followed by a seizure that affects the entire brain (secondary generalization).

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

2. What you need to know before taking Feoxan

Do not take Feoxan:

• if you are allergic to eslicarbazepine acetate, to other carbamate 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 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 to take eslicarbazepine.

Inform your doctor immediately:

• if you develop blisters or peeling of the skin and/or mucous membranes, rash, swallowing or breathing problems, 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 consciousness, which could be signs of low blood levels of salts.

Inform your doctor:

• if you have kidney problems. Your doctor may need to adjust the dose. Eslicarbazepine is not recommended in patients with severe kidney disease;
• if you have liver problems. Eslicarbazepine 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, discuss it with 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 an extended electrical discharge that affects both sides of the brain.

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

Eslicarbazepine may make you feel dizzy and/or drowsy, particularly at the start of treatment. Be especially careful while taking eslicarbazepine to avoid accidental injuries, such as falls.

Be especially careful with eslicarbazepine.

In post-marketing experience, in patients treated with eslicarbazepine, 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 eslicarbazepine and consult 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 in these patients. Your doctor may advise you on the need for such a blood test before taking eslicarbazepine.

Children

Eslicarbazepine should not be given to children under 6 years of age.

Taking Feoxan 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 eslicarbazepine works, or eslicarbazepine may affect the way other medicines work. Tell your doctor if you are taking:

• phenytoin (a medicine used to treat epilepsy), as your doctor may need to adjust the dose;
• carbamazepine (a medicine used to treat epilepsy), as your doctor may need to adjust the dose, 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 doctor may need to adjust the dose;
• rosuvastatin, a medicine used to lower cholesterol levels;
• the anticoagulant warfarin;
• monoamine oxidase inhibitors (MAOIs), antidepressants;
• do not take oxcarbazepine (a medicine used to treat epilepsy) with eslicarbazepine, as it is not known if it is safe to take these two medicines together.

See the section "Pregnancy and breast-feeding" for recommendations on contraception.

Pregnancy and breast-feeding

Eslicarbazepine acetate should not be used during pregnancy, as its effects on pregnancy and the unborn child are not known.

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

There are 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 children of women who take antiepileptic medicines, particularly when taking more than one antiepileptic medicine at the same time.

If you are pregnant or think you may be pregnant, inform 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 to you and your unborn child. Your doctor may decide to change your treatment.

If you are a woman of childbearing age and are not planning to become pregnant, you should use an effective method of contraception during treatment with eslicarbazepine acetate. Eslicarbazepine acetate may affect the effectiveness of hormonal contraceptives, such as the contraceptive pill, and make them less effective in preventing pregnancy. Therefore, you are advised to use other safe and effective methods of contraception while taking eslicarbazepine. Talk to your doctor, who will discuss with you the most suitable type of contraception to use while taking eslicarbazepine acetate. If you stop taking eslicarbazepine acetate, you should continue to use an effective method of contraception until the end of your current menstrual cycle. If you take eslicarbazepine acetate 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 taking eslicarbazepine acetate. It is not known if it passes into breast milk.

Driving and using machines

Eslicarbazepine 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 Feoxan

Always take this medicine exactly as your doctor has told you. If you are not sure, check with your doctor or pharmacist.

Form and route of administration

Eslicarbazepine is taken by mouth. Swallow the tablet with a glass of water. Eslicarbazepine can be taken with or without food.

If you take more Feoxan than you should

If you accidentally take more eslicarbazepine 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 package with you, so that the doctor knows what you have taken.

In case of overdose or accidental ingestion, consult your doctor or pharmacist immediately or call the Toxicology Information Service, telephone: 91 562 04 20, indicating the medicine and the amount taken.

If you forget to take Feoxan

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

If you stop taking Feoxan

Do not stop taking the tablets suddenly. If you do, you are at risk of having more seizures. Your doctor will decide how long you should take eslicarbazepine. If your doctor decides to stop your treatment with eslicarbazepine, 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.
