1. What is Lamotrigine Kern Pharma and what is it used for

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

Lamotrigine Kern Pharma is used for the treatment of epilepsybecause it blocks the signals in the brain that trigger seizures (attacks).

• In adults and children over 13 years of age, lamotrigine can be used alone or in combination with other medicines, for the treatment of epilepsy. Lamotrigine can also be used in combination 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, lamotrigine can be used in combination with other medicines for the treatment of the same diseases. It can also be used alone for the treatment of a type of epilepsy called typical absence seizures.

Lamotrigine Kern Pharma is also used for the treatment of bipolar disorder. People with bipolar disorder (formerly called manic-depressive disorder) suffer from radical mood swings, with periods of mania (excitement or euphoria) alternating with periods of depression (deep sadness or despair). In adults over 18 years of age, Lamotrigine Kern Pharma can be used to prevent the depressive episodes that occur in bipolar disorder, either alone or in combination with other medicines. It is not known how lamotrigine works in the brain to have this effect.

2. What you need to know before you take Lamotrigine Kern Pharma

Do not take Lamotrigine Kern Pharma

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

If this is the case:

• Tell your doctor, and do not take this medicine.

Warnings and precautions

Before taking lamotrigine, your doctor needs to know:

• If you have kidney problems.
• If you have ever developed a skin rash when taking lamotrigine or other medicines for epilepsy.
• 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 sunlight or artificial light (e.g., in a solarium). Your doctor will check your treatment and may advise you to avoid sunlight or protect yourself from the sun (e.g., use sunscreen and/or protective clothing).

If this is the case:

• Tell your doctor, who will decide to reduce your dose or determine that lamotrigine is not suitable for you.

It is essential to be aware of the symptoms:

Ask your doctor for help immediately if, after starting to take this medicine, you show any of these symptoms:

These symptoms include:

• Skin reaction, such as redness or rash.
• Irritation in the mouth or eyes.
• High temperature (fever), flu-like symptoms, or drowsiness (lethargy).
• Swelling around the face or inflammation of the glands in the neck, armpits, and groin.
• Bleeding or unexpected bruising, or fingers turning blue.
• Irritation of the throat, or more infections (such as colds) than usual.

It is more likely that these symptoms will occur during the first few months of treatment with lamotrigine, especially if you start treatment with a dose that is too high or if your dose is increased too quickly; it is also more likely to occur if you are taking this medicine with another medicine called valproate. Children are more likely than adults to suffer from these side effects.

If the symptoms listed above are not treated, they can become more serious problems, such as organ failure or a severe skin disease.

Life-threatening skin rashes (Stevens-Johnson syndrome and toxic epidermal necrolysis) have been described with the use of lamotrigine, initially appearing as red, circular spots, often with a central blister.

Other additional signs that may appear are sores in the mouth, throat, nose, genitals, and conjunctivitis (swollen and red eyes).

These life-threatening skin rashes are often accompanied by flu-like symptoms. The rash can progress to the formation of widespread blisters or peeling of the skin.

The period of highest risk of severe skin reactions is during the first few weeks of treatment.

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 lamotrigine.

If you have developed Stevens-Johnson syndrome or toxic epidermal necrolysis with the use of lamotrigine, you should not use lamotrigine again at any time.

If you develop a rash or these skin symptoms, stop taking lamotrigine, go to a doctor immediately, and inform them that you are taking this medicine. Your doctor will decide whether you need to undergo tests to assess liver, kidney, or blood function.

Thoughts of self-harm or suicide:

Antiepileptic medicines are used to treat different diseases, including epilepsy and bipolar disorder. People with bipolar disorder may have had thoughts of self-harm or suicide on occasion. 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 lamotrigine:

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

A small number of people who were treated with antiepileptics like lamotrigine 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 Lamotrigine Kern Pharma for epilepsy:

In some types of epilepsy, during treatment with lamotrigine, seizures may occasionally worsen or occur more frequently. Some patients may experience severe seizures that can cause serious health problems. If you notice that you are having seizures more often or if you experience severe seizures while taking this medicine:

• Go to a doctor immediately.

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

Brugada syndrome

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

Hemophagocytic lymphohistiocytosis (HLH)

Cases of a rare but very serious reaction of the immune system 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

If you are breastfeeding or plan to start breastfeeding, consult your doctor or pharmacist before using this medicine. The active ingredient of Lamotrigine Kern Pharma passes into breast milk and may affect your baby. Your doctor will discuss the risks and benefits of breastfeeding while taking this medicine and will perform periodic reviews of your baby if you decide to start breastfeeding, as it may cause drowsiness, rash, or poor weight gain. Inform your doctor if you notice any of these symptoms in your baby.

Using Lamotrigine Kern Pharma with other medicines

Tell your doctor or pharmacist that you are using, have recently used, or might use any other medicines.

If you are using certain medicines, your doctor may need to check the dose of lamotrigine. These include:

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

• Tell your doctor if you are using any of these medicines.

Some medicines interact with lamotrigine or make it more likely to cause 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
• olanzapine, used for the treatment of mental health problems
• risperidone, used for the treatment of mental health problems
• rifampicin, an antibiotic
• a combination of lopinavir and ritonavir, used for the treatment of HIV infection (AIDS)
• hormonal contraceptives, such as the Pill (see below).

• Tell your doctor if you are using, or if you start or stop using, any of these medicines.

Hormonal contraceptives (such as the Pill) may affect how this medicine works. Your doctor may recommend that you use a specific hormonal contraceptive or another method of contraception, such as condoms, diaphragm, or IUD. If you are taking a hormonal contraceptive like the Pill, your doctor may ask you to have blood tests to check the level of lamotrigine. If you are thinking of starting to use a hormonal contraceptive:

• Tell your doctor, as they will indicate which contraceptive methods are most suitable for you.

It is possible that the administration of lamotrigine may alter the effect of hormonal contraceptives, although it is unlikely to reduce their effectiveness. If you are using a hormonal contraceptive and experience changes in your menstrual cycle, such as intermenstrual bleeding or spotting:

• Tell your doctor. These may be signs that lamotrigine is affecting the way your contraceptive works.

Pregnancy and breastfeeding

• If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor before using this medicine.

You should not stop treatment for epilepsy while pregnant. However, there is a higher risk of birth defects in newborns whose mothers took lamotrigine during pregnancy. These defects include cleft lip or palate. Your doctor may advise you to take folic acid supplements if you are planning to become pregnant and during pregnancy.

Pregnancy may alter the effectiveness of treatment with lamotrigine, so your doctor may ask you to have a blood test to check the levels of lamotrigine and adjust your dose accordingly.

• Consult your doctor if you are breastfeeding or plan to start breastfeeding: the active ingredient (lamotrigine) passes into breast milk and may affect your baby. Your doctor will discuss the risks and benefits of breastfeeding while taking this medicine. If you decide to start breastfeeding, the doctor will perform periodic reviews of your baby.

Driving and using machines

Lamotrigine may cause symptoms such as drowsiness, dizziness, or changes in vision, and may reduce your reaction time. These effects, as well as the disease itself, may make it difficult for you to drive vehicles or operate machines. Therefore, do not drive, operate machines, or engage in other activities that require special attention until your doctor assesses your response to this medicine.

Lamotrigine Kern Pharma contains sorbitol

This medicine contains sorbitol. If your doctor has told you that you have an intolerance to certain sugars, consult them before taking this medicine.

3. How to take Lamotrigina Kern Pharma

Follow the instructions for taking this medicine exactly as indicated by your doctor. If you are in doubt, consult your doctor or pharmacist again.

What dose of Lamotrigina Kern Pharma to take:

It may take some time for your doctor to find the most suitable dose of lamotrigine for you. The dose you should take will depend on:

Your doctor will ask you to start treatment with a low dose and gradually increase the dose until you reach the most suitable dose for you (called the effective dose). Never take more lamotrigine than your doctor has prescribed.

Normally, the effective dose of lamotrigine for adults and children over 12 years of age is between 100 mg and 400 mg per day.

For children between 2 and 12 years of age, the effective dose depends on their body weight, usually between 1 mg and 15 mg per kilogram of body weight, up to a maximum of 400 mg per day.

How to take the dose of Lamotrigina Kern Pharma:

Take your dose of lamotrigine once or twice a day, as advised by your doctor. You can take it with or without food.

• Always take the full dose that your doctor has prescribed. Never take part of the tablet.

Your doctor may advise you to start or stop taking other medicines, depending on the conditions you are being treated for and how you respond to treatment.

Take the dispersible tablets of lamotrigine by swallowing them whole with a little water or by dissolving them in water:

If you chew the tablet:

You may need to drink a little more water to help the tablet dissolve in your mouth. After swallowing, drink a little more water to make sure you have taken all the medicine.

To dissolve the medicine (make a liquid medicine):

• Put the tablet in a glass that contains enough water to cover the tablet completely.
• Shake to dissolve or wait for a minute until the tablet is completely dissolved.

You must take this medicine for as long as your doctor recommends. Do not stop treatment until your doctor tells you to.

If you are taking Lamotrigina Kern Pharma for the treatment of epilepsy:

To stop taking this medicine, it is essential to reduce the dose gradually over approximately 2 weeks. If you stop taking lamotrigine suddenly, you may experience seizures again or your condition may worsen.

If you are taking Lamotrigina Kern Pharma for bipolar disorder:

This medicine may take some time to work, so it is unlikely that you will feel better immediately. To stop taking lamotrigine, you do not need to reduce the dose gradually. However, before stopping treatment with this medicine, you must consult your doctor.
