6.Contents of the pack and additional information

Crisomet belongs to a group of medications calledantiepileptic drugs. It can be used to treat two diseases: epilepsy and bipolar disorder.

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

• In adults and children 13 years of age and older, Crisomet can be used alone or in combination with other medications to treat epilepsy. Crisomet 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, Crisomet can be used in combination with other medications to treat the same diseases. It can also be used without combining with other medications to treat a type of epilepsy called typical absence seizures.

Crisomet 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, Crisomet can be used to prevent the periods of depression that occur in bipolar disorder, either alone or in combination with other medications. The exact mechanism of action of Crisomet in the brain is not known.

Do not take Crisomet:

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

If this is your case:

?Inform your doctorand do not take Crisomet.

Warnings and precautions

Be especially careful with Crisomet

Consult your doctor or pharmacist before startingto take Crisomet:

• if you have any kidney problems
• if you have ever had a skin rashafter taking lamotrigine or other medicines for bipolar disorder or epilepsy
• if you have skin rashes 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 sunscreen and/or protective clothing)
• if you have ever had meningitis after taking lamotrigine(read the description of these symptoms in section 4 of this leaflet: Rare side effects)
• if you are already taking medicines that contain lamotrigine
• if you have a condition called Brugada Syndrome or other heart problems.Lamotrigine may cause abnormalities in the electrocardiogram (ECG) that can lead to arrhythmias (abnormal heart rhythm).

If this is your case:

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

Important information about potentially life-threatening reactions

A small number of people taking Crisomet have had allergic reactions or skin reactions that can be potentially 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 Crisomet.This risk may be associated with a genetic variant in people of Asian origin (mainly Chinese Han and Thai). If you are of such origin and have been detected with this genetic variant (HLA-B*1502), talk to your doctor before taking Crisomet.

?Read the description of these symptoms in section 4 of this leaflet“Reactions that can be potentially life-threatening: consult your doctor immediately”.

Lymphohistiocytosis hemophagocytic (LHH)

Cases of a rare but severe 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, including Crisomet, are used to treat different conditions, including epilepsy and bipolar disorder. People with bipolar disorder mayhave occasional 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 Crisomet:

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

It may be helpful 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 Crisomet have also had thoughts of self-harm or suicide. If you ever have these thoughts, contact your doctor immediately.

If you are taking Crisomet for epilepsy

Seizures in some types of epilepsy may occasionally worsen or occur more frequently while taking Crisomet. 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 Crisomet:

?Go to a doctor immediately.

Crisomet 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 behaviors in children and adolescents under 18 years.

Other medicines and Crisomet

Inform your doctor or pharmacist if you are taking, have taken recently, or may need to take any othermedicine, 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 Crisomet. These medicines include:

• oxcarbazepine, felbamate, gabapentin, levetiracetam, pregabalin, topiramate, or zonisamide, used for the treatment ofepilepsy
• lithium, olanzapine, or aripiprazole, used for the treatment ofmental health problems
• bupropion, used for the treatment ofmental health problemsor to quit smoking
• paracetamol, used to treatpainandfever

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

Some medicines interact with Crisomet 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, primidone, or phenobarbital, 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 Crisomet 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 Crisomet 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.

Crisomet 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 loss between periods:

?Inform your doctor. These may be signs that Crisomet is affecting the way your contraceptive works.

Like all medications, this medication may cause side effects, although not everyone will experience them.

Reactionsthatpotentiallycan be life-threatening:consult yourdoctor immediately.

A small number of people taking Crisomet have allergic reactions or skin reactions that can potentially be life-threatening, 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 Crisomet, especially if the initial dose is very high or if the dose increase is very rapid, or if you are taking Crisomet with another medication 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),widespread rash with blisters andpeeling of theskin, which occurs especially around the mouth, nose, eyes, and genitals (Stevens-Johnson syndrome), peelingin a large area of the skin(more than 30% of the body surface –toxic epidermal necrolysis)or 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 sores, throat, nose, or genital
• eye pain or having red or swollen eyes (conjunctivitis)
• high temperature (fever), symptoms similar to the flu or drowsiness (somnolence)
• swelling around the face, or inflammationof the lymph nodesin 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 severe side effects.However, you should be aware that they can potentially be life-threatening 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 Crisomet.If you have developed Stevens-Johnson syndrome or toxic epidermal necrolysis, your doctor will instruct you never to take lamotrigine again.
