1. What is OXCARBAZEPINE TECNIGEN and what is it used for

Oxcarbazepine belongs to a group of medicines called anticonvulsants or antiepileptics. Antiepileptics, such as oxcarbazepine, are the standard treatment for epilepsy.

Patients diagnosed with epilepsy have had repeated seizures or convulsions. Seizures occur due to a temporary failure in the brain's electrical system. Normally, brain cells coordinate body movements by sending signals through muscle nerves in an orderly organized manner. The result can be uncoordinated muscle activity known as an epileptic seizure.

Oxcarbazepine acts by keeping the brain's overexcited nerve cells under control, thereby suppressing or reducing the frequency of such seizures.

Oxcarbazepine is used to treat partial epileptic seizures with or without secondary generalization with tonic-clonic seizures. Partial seizures affect a limited area of the brain but can spread to the entire brain and cause generalized tonic-clonic seizures. There are two types of partial seizures: simple and complex. In simple partial seizures, the patient remains conscious, while in complex seizures, the state of consciousness is altered.

Normally, your doctor will try to find the medicine that works best for you, but in severe cases of epilepsy, you may need a combination of two or more medicines to control the seizures. Oxcarbazepine can be used alone or in combination with other antiepileptics. Oxcarbazepine is indicated for the treatment of adults and children aged 6 years or older.

2. BEFORE TAKING OXCARBAZEPINE TECNIGEN

Follow carefully all the instructions given by your doctor, even if they differ from those in this leaflet.

Do not take Oxcarbazepine TecniGen:

If you are allergic (hypersensitive) to the active ingredient (oxcarbazepine) or to any of the other ingredients of this medicine (see section 6 "Further information")

Be especially careful with Oxcarbazepine TecniGen:

see section 4 "Possible side effects")

If you have any of the conditions described above, inform your doctor before taking oxcarbazepine.

see section 4 "Possible side effects")

The risk of severe skin reactions in patients of Chinese Han or Thai origin associated with carbamazepine or related chemical compounds can be predicted by analyzing a blood sample from these patients. Your doctor will advise you if a blood test is necessary before taking oxcarbazepine.

A small number of people who have been treated with antiepileptics such as oxcarbazepine have had thoughts of self-harm or suicide. If at any time you have these thoughts, contact your doctor immediately.

Taking other medicines:

Please consult your doctor or pharmacist if you are taking or have recently taken other medicines, including those obtained without a prescription.

Especially in the case of:

• oral contraceptives ("the pill")
• other antiepileptic medicines (such as carbamazepine, phenobarbital, phenytoin, or lamotrigine)
• medicines that reduce blood sodium levels, such as diuretics (used to help the kidneys eliminate salt and water, increasing urine production), desmopressin, and non-steroidal anti-inflammatory drugs (such as indomethacin)
• lithium and monoamine oxidase inhibitors (medicines used to treat mood disorders and some types of depression)
• Medicines that control the immune system of your body (such as cyclosporine, tacrolimus)

Taking Oxcarbazepine TecniGen with food and drinks:

During treatment with oxcarbazepine, avoid taking alcoholic beverages, as they may increase the sedative effects of the medicine.

Pregnancy:

Inform your doctor if you are pregnant or plan to become pregnant.

It is essential to control epileptic seizures during pregnancy. However, there may be a risk to your baby if you take antiepileptic medicines during pregnancy.

Congenital malformations

Studies have not shown an increased risk of congenital malformations associated with oxcarbazepine administered during pregnancy; however, it cannot be completely ruled out that there is a risk of congenital malformations in the fetus.

Neurodevelopmental disorders

Some studies have shown that exposure to oxcarbazepine in the womb affects the development of brain function (neurodevelopment) in children, while in other studies, this effect has not been observed. The possibility that there is an effect on neurodevelopment cannot be ruled out.

Birth weight

If you use Oxcarbazepine TecniGen during pregnancy, your child may be small and weigh less than expected at birth [small size for gestational age (SGA)]. Among women with epilepsy, in one study, about 15 out of 100 children born to mothers who had taken oxcarbazepine during pregnancy were smaller and weighed less than expected at birth, compared to about 11 out of 100 children born to women who had not taken anticonvulsant medication during pregnancy.

Your doctor will inform you of the benefits and possible risks of treatment and help you decide whether you should take oxcarbazepine. Do not stop your treatment with oxcarbazepine without consulting your doctor.

Consult your doctor or pharmacist before taking any medicine during pregnancy.

Breast-feeding:

If you are taking this medicine, consult your doctor before breast-feeding. The active ingredient of oxcarbazepine passes into breast milk. Although the available data suggest that the amount of oxcarbazepine that passes to the breastfed child is low, a risk of adverse effects in the baby cannot be ruled out. Your doctor will inform you of the benefits and potential risks of breast-feeding while using oxcarbazepine. If you are breast-feeding during treatment with oxcarbazepine and think that your baby is experiencing any adverse effects, such as excessive sleepiness or poor weight gain, inform your doctor immediately.

Driving and using machines:

Oxcarbazepine may cause symptoms such as drowsiness, dizziness, or vision changes, and may decrease 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.

3. HOW TO TAKE OXCARBAZEPINE TECNIGEN

Follow carefully all the instructions given by your doctor, even if they differ from those in this leaflet.

Use in adults

Oxcarbazepine TecniGen should be taken twice a day, every day, and approximately at the same time, unless your doctor tells you otherwise. The best way to control epilepsy is to take the tablets at the same time every day. This will also help you remember when to take the tablets.

Generally, the initial dose of Oxcarbazepine TecniGen in adults (including the elderly) is 600 mg per day. Take a dose of 300 mg twice a day. If necessary, your doctor may gradually increase this dose to achieve the desired results. This usually occurs at doses between 600 and 2,400 mg per day.

The dose is the same if Oxcarbazepine TecniGen is taken with another antiepileptic medicine.

The initial dose for patients with kidney disease (renal insufficiency) is half the normal initial dose.

If you have severe liver disease, your doctor will adjust the dose.

Use in children

Oxcarbazepine TecniGen can be used in children aged 6 years or older.

The dose for children is calculated based on their weight. The initial dose is 8-10 mg/kg of body weight per day, administered in two doses. For example, a child weighing 30 kg will start treatment with a dose of 150 mg twice a day. If necessary, the dose will be gradually increased to achieve the desired results. A normal maintenance dose for a child is 30 mg/kg per day. The maximum dose for a child is 46 mg per kg of body weight per day.

How to take Oxcarbazepine TecniGen

The score line on the Oxcarbazepine TecniGen tablets allows the tablet to be divided into two equal doses, making it easier for the patient to swallow the tablets

For children who cannot swallow the tablets or when the required dose cannot be administered using tablets, other pharmaceutical forms containing oxcarbazepine are available. Oxcarbazepine TecniGen can be taken with or without food.

When and for how long to take Oxcarbazepine TecniGen

Your doctor will inform you how long your treatment or your child's treatment will last. The duration of treatment is based on the type of seizures you or your child experience and may require continuous treatment for several years to control the epileptic seizures. Do not change the dose or stop treatment without talking to your doctor first.

If you take more Oxcarbazepine TecniGen than you should

If you have taken many more tablets than your doctor prescribed, inform your doctor or go to the nearest hospital.

Symptoms of overdose: drowsiness, dizziness, nausea, vomiting, increased motor activity, numbness, confusion, muscle contractions, or significant worsening of seizures, coordination problems, and/or involuntary eye movements.

If you forget to take Oxcarbazepine TecniGen

If you have forgotten a single dose, take it as soon as you can, except if it is almost time for the next dose; in this case, wait and return to your usual dosing schedule. Do not take a double dose to make up for forgotten doses.

If you are unsure or have forgotten several doses, inform your doctor.

If you stop taking Oxcarbazepine TecniGen

Do not stop taking your medicine without consulting your doctor first.

To prevent a sudden worsening of seizures, do not stop treatment abruptly. If you stop your treatment, it should be done gradually, as your doctor has indicated.

If you have any other questions about the use of this product, ask your doctor or pharmacist.
