Lamotrigina Normon belongs to a group of medications calledantiepileptic drugs. It can be used to treat two diseases: epilepsyand bipolar disorder.

Lamotrigina Normon is used to treat epilepsy becauseit blocks signals in the brain that trigger epileptic seizures (attacks).

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

Lamotrigina Normon is also used to treat bipolar disorder.

People with bipolar disorder (formerly known as manic-depressive disorder) experience radical mood swings, with periods of mania (excitement or euphoria) alternating with periods of depression (deep sadness or desperation). In adults 18 years of age and older, Lamotrigina Normon can be used to prevent periods of depression that occur in bipolar disorder, either alone or in combination with other medications. The exact mechanism of action of lamotrigine in the brain is not known.

Do not take Lamotrigina Normon:

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

If this is the case:

Inform your doctor, and do not take Lamotrigina Normon.

Warnings and precautions

Consult your doctor or pharmacist before starting to take Lamotrigina Normon:

• if you have any kidney problems.
• if you have ever had a skin rash after taking lamotrigine or other medicines for bipolar disorder or epilepsy.See section 4 of this leaflet for more information on rare side effects.
• if you have ever had meningitis after taking lamotrigine.See section 4 of this leaflet for more information on rare side effects.
• if you are already taking medicines that contain lamotrigine.
• if you have had a skin rash after taking lamotrigine or other medicines for bipolar disorder or epilepsy, or if you suffer from skin rashes or sunburn after taking lamotrigine and exposure to the sun or artificial light (for example, in a sunbed). Your doctor will check your treatment and may advise you to avoid the sun or protect yourself from the sun (for example, by using a sun cream and/or protective clothing).

If this is the case:

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

Important information about potentially life-threatening reactions

A small number of people taking lamotrigine have had allergic reactions or skin reactions that can be life-threatening, which can lead to more serious problems if not treated. These reactions can 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 Lamotrigina Normon. 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 Lamotrigina Normon.

See section 4 of this leaflet for more information on these symptoms.

Thoughts of self-harm or suicide

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

• when you start 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 Lamotrigina Normon:

See 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 behavior.

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

If you are taking Lamotrigina Normon for epilepsy:

Seizures in some types of epilepsy may occasionally get worse or happen more often while you are taking Lamotrigina Normon. Some patients may experience severe seizures, which can cause serious health problems. If seizures happen more often or if you experience severe seizures while taking Lamotrigina Normon:

See a doctor immediately.

Lamotrigina Normon should not be given to children under 18 years old for the treatment of bipolar disorder.Medicines used to treat depression and other mental health problems increase the risk of thoughts and behaviors of self-harm or suicide in children and adolescents under 18 years old.

Taking Lamotrigina Normon with other medicines

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 bought without a prescription.

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

• oxcarbazepine, felbamate, gabapentin, levetiracetam, pregabalin, topiramate, or zonisamideused for the treatment of epilepsy
• lithium, olanzapine, or aripiprazole, used for the treatment of mental health problems
• bupropion, used for the treatment of mental health problems or to quit smoking

Inform your doctorif you are using any of these medicines.

Some medicines interact with Lamotrigina Normon or make it more likely for people to have side effects. These include:

• valproate, used for the treatment of epilepsy and mental health problems
• carbamazepine, used for the treatment of epilepsy and mental health problems
• phenytoin, primidone, or phenobarbital, used for the treatment of epilepsy
• risperidone, used for the treatment of mental health problems
• rifampicin, which is an antibiotic
• medicines used to treat HIV infection (AIDS) (a combination of lopinavir and ritonavir or atazanavir and ritonavir)
• hormonal contraceptives, such as the pill (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 how Lamotrigina Normon works.

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

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

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

Inform your doctor. These may be signs that lamotrigine is affecting the way your hormonal contraceptive works.

Brugada syndrome

Brugada syndrome is a genetic disorder that causes abnormal heart electrical activity. Lamotrigina may cause abnormalities in the electrocardiogram (ECG) that can lead to arrhythmias (abnormal heart rhythm). See your doctor if you have this condition.

Lymphohistiocytosis hemophagocytic (LHH)

Cases of a rare but severe immune system reaction have been reported in patients taking lamotrigine. Contact your doctor or pharmacist immediately if you experience any of the following symptoms while taking lamotrigine: fever, rash, neurological symptoms (e.g., spasms or tremors, confusion, changes in brain function).

Pregnancy and breastfeeding

• Do not stop your treatment without consulting your doctor.This is particularly important if you have epilepsy.
• Pregnancy may affect the effectiveness of treatment with Lamotrigina Normon, so you may need to have blood tests and have your dose adjusted.
• If you take Lamotrigina Normon 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, see your doctor or pharmacist before using this medicine.Lamotrigine passes into breast milk and may affect your baby. Your doctor will discuss the risks and benefits of breastfeeding while taking Lamotrigina Normon 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 notice any of these symptoms in your baby.

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 lamotrigine have had 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 Lamotrigine Normon, especially if the initial dose is very high or if the dose increase is very rapid, or if you are taking Lamotrigine Normon with another medicine called valproate.Some of these symptoms are more common in children, so parents should pay special attention.

The symptoms of these reactions include:

• skin eruptions or redness,which can lead to skin reactions that may threaten life, including widespread rash with blisters and skin peeling, which occurs especially around the mouth, nose, eyes, and genitals (Stevens-Johnson syndrome), widespread skin peeling with liver, blood, and other organ involvement (toxic epidermal necrolysis), or widespread skin rash with liver, blood, and other organ involvement (drug reaction with eosinophilia and systemic symptoms, also known as DRESS);
• mouth ulcers, throat, nose, or genital ulcers;
• mouth or eye pain or redness (conjunctivitis);
• high temperature (fever), flu-like symptoms, 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 more frequent infections (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 involvement, including the liver and kidneys.

In many cases, these symptoms can be signs of less severe 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 evaluate the function of the liver, kidneys, or blood and may instruct you to stop taking Lamotrigine Normon. If you have developed Stevens-Johnson syndrome or toxic epidermal necrolysis, your doctor will instruct you never to take lamotrigine again.
