1. What Crisomet is and what it is used for

Crisomet belongs to a group of medicines called antiepileptics. It can be used for the treatment of two conditions: epilepsy and bipolar disorder.

Crisomet is used for the treatment of epilepsy because itblocks the signals in the brain that trigger epileptic seizures (fits).

• In adults and children aged 13 years and over, Crisomet can be used alone or in combination with other medicines for the treatment of epilepsy. Crisomet can also be used with other medicines for the treatment of 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 medicines for the treatment of the same conditions. It can also be used on its own for the treatment of a type of epilepsy called typical absence seizures.

Crisomet is also used for the treatment of bipolar disorder.

People with bipolar disorder (previously called manic-depressive illness) have extreme mood swings, with periods of mania (excitement or euphoria) alternating with periods of depression (deep sadness or despair). In adults aged 18 years and over, Crisomet can be used to prevent the periods of depression that occur in bipolar disorder, either on its own or in combination with other medicines. It is not known how Crisomet works in the brain to have this effect.

2. What you need to know before you take Crisomet

Do not take Crisomet:

If this applies to you:

Warnings and precautions

Be especially careful with Crisomet

Tell your doctor or pharmacist before you start taking Crisomet:

• . Your doctor will check your treatment and may advise you to avoid sunlight or use protective measures (such as sun cream and clothing) to protect your skin.
• (read the description of these symptoms in section 4 of this leaflet: Rare side effects).
• Brugada Syndrome is a genetic condition that affects the electrical activity of the heart. Lamotrigine can cause changes in the electrocardiogram (ECG) that can lead to irregular heart rhythms.

If this applies to you:

? Tell your doctor, who will decide whether to lower your dose or whether Crisomet is suitable for you.

Important information about reactions that may potentially be life-threatening

A small number of people taking Crisomet have allergic reactions or skin reactions that may be life-threatening, which can lead to more serious problems if not treated. These reactions can include Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), 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 Han Chinese 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 may potentially be life-threatening: consult your doctor immediately”.

Hemophagocytic lymphohistiocytosis (HLH)

There have been reports of a rare but very serious reaction of the immune system in patients taking lamotrigine.

• Contact your doctor or pharmacist immediatelyif you get any of the following symptoms while taking lamotrigine: fever, rash, neurological symptoms (e.g., spasms or tremors, confusion, changes in brain function).

Thoughts of self-harm or suicide

Antiepileptic medicines are used to treat different 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:

• when you first 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 Crisomet:

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

It may be helpful for you to tell a family member, carer, or close friend that you are taking Crisomet 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 were taking antiepileptics, such as Crisomet, have also had thoughts of self-harm or suicide. If you have these thoughts at any time, contact your doctor immediately.

If you are taking Crisomet for epilepsy

Seizures in some types of epilepsy may occasionally become worse or happen more often while you are taking Crisomet. 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 Crisomet:

? See a doctor immediately.

Crisomet must not be given to children under 18 years for the treatment of bipolar disorder.Medicines for the treatment of depression and other mental health conditions increase the risk of suicidal thoughts and behaviors in children and adolescents under 18 years.

Other medicines and Crisomet

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines, including herbal medicines or other medicines that you have bought without a prescription.

Your doctor needs to know if you are taking other medicines to treat epilepsy or mental health conditions. This is to make sure you take the correct dose of Crisomet. These medicines include:

• oxcarbazepine, felbamate, gabapentin, levetiracetam, pregabalin, topiramateor zonisamide, used to treat epilepsy
• lithium, olanzapine or aripiprazole, used to treat mental health conditions
• bupropion, used to treat mental health conditionsor to stop smoking
• paracetamol, used to treat painand fever.

? Tell your doctor if you are taking any of these medicines.

Some medicines interact with Crisomet or make it more likely that you will have side effects. These include:

• valproate, used to treat epilepsyand mental health conditions
• carbamazepine, used to treat epilepsyand mental health conditions
• phenytoin, primidone or phenobarbital, used to treat epilepsy
• risperidone, used to treat mental health conditions
• rifampicin, which is an antibiotic
• medicines used to treat HIV infection(a combination of lopinavir and ritonavir or atazanavir and ritonavir)
• hormonal contraceptives, such as the pill(see below).

? Tell your doctor if you are taking any of these medicines, or if you start or stop taking any of these medicines.

Hormonal contraceptives (such as the pill) may affect how Crisomet works.

Your doctor may recommend that you use a specific hormonal contraceptive or another method of contraception, such as condoms, a diaphragm, or an intrauterine device (IUD). If you are taking a hormonal contraceptive, such as the pill, your doctor may do a blood test to check the levels of Crisomet. If you are taking a hormonal contraceptive or plan to start using one:

? Talk to your doctor, as they will tell you which contraceptive methods are suitable for you.

Crisomet may also affect how hormonal contraceptives work, although this is unlikely to affect their effectiveness. If you are using a hormonal contraceptive and you notice changes in your menstrual cycle, such as breakthrough bleeding or spotting:

? Tell your doctor. These may be signs that Crisomet is affecting how your contraceptive is working.

Pregnancy and breastfeeding

? If you are pregnant, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

• Do not stop your treatment without talking to your doctor. This is particularly important if you have epilepsy.
• Pregnancy may affect how well Crisomet works, so you may need to have a blood test and your dose adjusted.
• If Crisomet is taken during the first 3 months of pregnancy, there may be a small increased risk of birth defects, including cleft lip or cleft palate.
• Your doctor may advise you to take folic acid supplements if you are planning to become pregnant and during pregnancy.

? If you are breastfeeding or planning to breastfeed, ask your doctor or pharmacist for advice before taking this medicine.

The active ingredient of Crisomet passes into breast milk and may affect your baby. Your doctor will discuss the risks and benefits of breastfeeding while taking Crisomet and will perform regular checks on your baby if you decide to breastfeed, as they may become sleepy, get a rash, or have poor weight gain. Tell your doctor if you notice any of these symptoms in your baby.

Driving and using machines

Crisomet can cause dizziness and double vision.

? Do not drive or use machines unless you are sure that you are not affected by these effects.

If you have epilepsy, ask your doctor about the possibility of driving or using machines.

• if you have any liver or kidney problems.

Your doctor will prescribe a low dose at the start of treatment and, gradually, increase the dose over several weeks until reaching the most suitable dose for you (called effective dose). Never take more Crisomet than your doctor has indicated.

Normally, the effective dose of Crisomet for adults and children 13 years of age and older is between 100 mg and 400 mg per day.

To stop taking Crisomet, it is essential that the dose is gradually reduced, over approximately 2 weeks. If you stop taking Crisomet suddenly, you may experience a return of epilepsy symptoms or the disease may worsen.

If you are taking Crisomet for bipolar disorder

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

4. Possible side effects

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

Reactionsthatcan potentially 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 few 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 called valproate. Some of these symptoms are more frequent in children, so parents should pay special attention to them.

The symptoms of these reactions include:

• skin rash or redness, which can lead to skin reactions that can be serious or, on occasion, potentially fatal, including rash with target-like lesions (erythema multiforme), widespread rash with blisters and skin peeling, which occurs especially around the mouth, nose, eyes, and genitals (Stevens-Johnson syndrome), peeling over 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 (drug reaction with eosinophilia and systemic symptoms, also known as DRESS syndrome)
• mouth ulcers, throat, nose, or genital ulcers
• mouth pain or red, swollen eyes(conjunctivitis)
• high temperature(fever), flu-like symptoms, or drowsiness (drowsiness)
• swelling around the faceor inflammation of the lymph nodesin the neck, armpits, or groin
• bleeding or unexpected bruising, or fingers turning blue
• sore throator experiencing more infections than usual (such as colds)
• increased liver enzyme levels in blood tests
• increased eosinophils, a type of white blood cell
• enlarged lymph nodes
• organ involvement, including the liver and kidneys.

In many cases, these symptoms can be signs of less severe adverse effects. However, you should be aware that they can potentially be life-threateningand 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 liver, kidney, or blood function and may advise you to interrupt treatment with Crisomet. If you have developed Stevens-Johnson syndrome or toxic epidermal necrolysis, your doctor will advise you to never take lamotrigine again.
