6.Contents of the package and additional information

Labileno belongs to a group of medications calledantiepileptics. It can be used for the treatment of two diseases: epilepsyand bipolar disorder.

Labileno is used for the treatment of epilepsybecause it blocks the signals in the brain that trigger epileptic seizures (attacks).

• In adults and children 13 years of age and older, Labileno can be used alone or in combination with other medications for the treatment of epilepsy. Labileno can also be used with other medications for the treatment of seizures caused by a condition called Lennox-Gastaut Syndrome.
• In children between 2 and 12 years of age, Labileno can be used in combination with other medications for the treatment of the same diseases. It can also be used without combining with other medications for the treatment of a type of epilepsy called typical absence seizures.

Labileno is also used for the treatment of bipolar disorder.

People with bipolar disorder (formerly known as manic-depressive disorder) experience radical mood changes, with periods of mania (excitement or euphoria) alternating with periods of depression (deep sadness or desperation). In adults 18 years of age and older, Labileno can be used to prevent the periods of depression that occur in bipolar disorder, either alone or in combination with other medications. The way Labileno acts in the brain to achieve this effect is not known.

Do not take Labileno:

• if you are allergic(hypersensitive) to lamotrigine or any of the other ingredients of this medicine (listed in section 6).

If this is the case:

?Inform your doctorand do not take Labileno.

Warnings and precautions

Be particularly careful with Labileno

Consult your doctor or pharmacist before starting to take Labileno:

• if you have any kidney problems
• if you have ever had a skin eruptionafter taking lamotrigine or other medicines for bipolar disorder or epilepsy
• if you suffer from skin eruptions or sunburn after taking lamotrigine and exposure to the sun or artificial light (for example, in a solarium). Your doctor will check your treatment and may advise you to avoid sunlight or protect yourself from the sun (for example, use a sun protection cream and/or protective clothing)
• if you have ever had meningitis after taking lamotrigine(see the description of these symptoms in section 4 of this leaflet: Rare side effects)
• if you are already taking medicines containing lamotrigine
• if you have a condition called Brugada syndrome or other heart problems.Brugada syndrome is a genetic disease that causes abnormal heart electrical activity. Lamotrigine may cause abnormalities in the electrocardiogram (ECG) that may lead to arrhythmias (abnormal heart rhythm).

If this is the case:

?Inform your doctor, who will decide to reduce the dose or determine that Labileno is not suitable for you.

Important information about potentially life-threatening reactions

A small number of people taking Labileno have had allergic reactions or skin reactions that may be life-threatening, which can lead to more serious problems if not treated. These reactions may include Stevens-Johnson syndrome (SSJ), toxic epidermal necrolysis (NET), and drug reaction with eosinophilia and systemic symptoms (DRESS). You need to know the symptoms of these reactions and be aware of them while taking Labileno.This risk may be associated with a genetic variant in people of Asian origin (mainly Chinese Han and Thai). If you are of this origin and have been detected with this genetic variant (HLA-B*1502), talk to your doctor before taking Labileno.

?Read the description of these symptoms in section 4 of this leaflet“Life-threatening reactions: consult your doctor immediately”.

Haemophagocytic lymphohistiocytosis (HLH)

Cases of a rare but serious immune system reaction have been reported in patients taking lamotrigine.

• Contact your doctor or pharmacist immediatelyif you experience any of the following symptoms while taking lamotrigine: fever, rash, neurological symptoms (e.g. spasms or tremor, confused state, cerebral function alterations).

Thoughts of self-harm or suicide

Antiepileptic drugs are used to treat various conditions, including epilepsy and bipolar disorder. People with bipolar disorder may sometimes have thoughts of self-harm or suicide. If you have bipolar disorder, you may be more likely to have these thoughts in the following situations:

• when starting treatment
• if you have had thoughts of self-harm or suicide before
• if you are under 25 years old.

If you have thoughts or experiences that worry you, or if you notice that you feel worse or develop new symptoms while taking Labileno:

?Consult your doctor as soon as possible or go to the nearest hospital.

It may be helpful for you to explain to a family member, carer or close friend that you may become depressed or have significant mood changes, and ask them to read this leaflet. You can ask them to tell you if they are worried about your depression or other changes in your behaviour.

A small number of people who have been treated with antiepileptic drugs like Labileno have also had thoughts of self-harm or suicide. If you ever have these thoughts, contact your doctor immediately.

If you are taking Labileno for epilepsy

Seizures in some types of epilepsy may occasionally worsen or occur more frequently while taking Labileno. Some patients may experience severe seizures, which can cause serious health problems. If seizures occur more frequently or if you experience severe seizures while taking Labileno:

?Go to a doctor immediately.

Labileno should not be administered to children under 18 years for the treatment of bipolar disorder. Medicines used to treat depression and other mental health problems increase the risk of suicidal thoughts and behaviours in children and adolescents under 18 years.

Other medicines and Labileno

Inform your doctor or pharmacist if you are taking, have taken recently or may need to take any other medicine,including herbal medicines or other medicines obtained without a prescription.

Your doctor needs to know if you are taking other medicines for the treatment of epilepsy or mental health problems. This is to ensure that you take the correct dose of Labileno. These medicines include:

• oxcarbazepine, felbamate, gabapentin, levetiracetam, pregabalin, topiramateorzonisamide, used for the treatment ofepilepsy
• lithium, olanzapine or aripiprazole, used for the treatment ofmental health problems
• bupropion, used for thetreatmentof mental health problemsor tostop smoking
• paracetamol,used to treatpainandfever.

?Inform your doctorif you are using any of these medicines.

Some medicines interact with Labileno or make people more likely to have side effects. These include:

• valproate, used for the treatment ofepilepsyandmental health problems
• carbamazepine, used for the treatment ofepilepsyandmental health problems
• phenytoin, primidoneorphenobarbital, used for the treatment ofepilepsy
• risperidone, used for the treatment ofmental health problems
• rifampicin, which is anantibiotic
• medicines used to treat HIV infection (a combination of lopinavir and ritonavir or atazanavir and ritonavir)
• hormonal contraceptives, such asthe pillcontraceptive(see below).

?Inform your doctorif you are using any of these medicines, or if you start or stop using any of these medicines.

Hormonal contraceptives (such as the pill) may affect the way Labileno works.

Your doctor may recommend a specific hormonal contraceptive, or suggest using a different method of contraception, such as condoms, diaphragm or IUD. If you are taking a hormonal contraceptive, such as the pill, your doctor may perform a blood test to check your Labileno levels. If you are using a hormonal contraceptive or plan to start using one:

?Consult your doctor, who will advise you on the most suitable methods of contraception for you.

Labileno may also affect the way hormonal contraceptives work, although it is unlikely to reduce their effectiveness. If you are using a hormonal contraceptive and notice changes in your menstrual cycle, such as intermenstrual bleeding or losses between periods:

?Inform your doctor. These may be signs that Labileno is affecting the way your contraceptive is working.

Pregnancy and breastfeeding

?If you are pregnant, think you may be pregnant or intend to become pregnant, consult your doctor or pharmacist before using this medicine.

• Do not stop your treatment without consulting your doctor. This is particularly important if you have epilepsy.
• The pregnancy may modify the effectiveness of Labileno treatment, so you may need to have a blood test and have your dose adjusted.
• If Labileno is taken during the first 3 months of pregnancy, there may be a small increase in the risk of birth defects, including cleft lip and/or palate.
• Your doctor may advise you to take folic acid supplements if you are planning to become pregnant and also during pregnancy.

?If you are breastfeeding or plan to start breastfeeding, consult your doctor or pharmacist before using this medicine.Labileno's active ingredient passes into breast milk and may affect your baby. Your doctor will discuss the risks and benefits of breastfeeding while taking Labileno and will perform regular checks on your baby if you decide to start breastfeeding, as your baby may experience drowsiness, rash or poor weight gain. Inform your doctor if you observe any of these symptoms in your baby.

If you are taking Labileno for the treatment of epilepsy

To stop taking Labileno,it is essential to gradually reduce the dose over approximately 2 weeks. If you stop taking Labileno suddenly, you may experience a relapse of the epilepsy symptoms or the disease may worsen.

If you are taking Labileno for bipolar disorder

Labileno may take some time to act, so it is unlikely that you will feel better immediately. If you stop taking Labileno, you do not need to gradually reduce your dose. However, before interrupting treatment with Labileno, you should consult with your doctor.

Like all medicines, this medicine can cause side effects, although not everyone will experience them.

Reactions that may potentially threaten life: consult your doctor immediately.

A small number of people taking Labileno have allergic reactions or skin reactions that may potentially threaten their life, which can lead to more serious problems if not treated.

It is more likely that these symptoms will appear during the first months of treatment with Labileno, especially if the initial dose is very high or if the dose increase is very rapid, or if you are taking Labileno with another medicine calledvalproate. Some of these symptoms are more common in children, so parents should pay special attention.

The symptoms of these reactions include:

• skin rashes or redness, which can lead to skin reactions that can be severe or, in some cases, potentially life-threatening, including a rash with lesions in the shape of a target (erythema multiforme), a widespread rash with blisters and skin peeling, which occurs especially around the mouth, nose, eyes, and genitals (Stevens-Johnson syndrome), widespread skin peeling in an extensive area of the body (more than 30% of the body surface –toxic epidermal necrolysis) or a widespread skin rash with liver, blood, and other organ involvement (pharmacological reaction with eosinophilia and systemic symptoms also known as drug reaction with eosinophilia and systemic symptoms (DRESS))
• mouth ulcers, throat, nose, or genital ulcers
• mouth or eye pain, or red or swollen eyes (conjunctivitis)
• high temperature (fever), symptoms similar to the flu or drowsiness (somnolence)
• swelling around the face, or inflammation of the lymph nodes in the neck, armpits, or groin
• unexplained bleeding or bruising, or fingers turning blue
• throat pain or experiencing more infections than usual (such as colds)
• increased levels of liver enzymes in blood tests
• increased levels of a type of white blood cell (eosinophils)
• enlarged lymph nodes
• organ damage, including the liver and kidneys.

In many cases, these symptoms can be signs of less serious side effects.However, you should be aware that they may potentially threaten life and can lead to more serious problems, such as organ failure, if not treated. If you notice any of these symptoms:

?Contact your doctor immediately.. Your doctor will decide if you need to undergo tests to assess the functioning of the liver, kidneys, or blood and may instruct you to stop taking Labileno. If you have developed Stevens-Johnson syndrome or toxic epidermal necrolysis, your doctor will instruct you never to take lamotrigine again.
