1. What is oxcarbazepine cinfa and what is it used for

What is oxcarbazepine cinfa

The active substance of oxcarbazepine cinfa is oxcarbazepine.

Oxcarbazepine belongs to a group of medicines called anticonvulsants or antiepileptics.

What is oxcarbazepine cinfa used for

Medicines like oxcarbazepine are the standard treatment for epilepsy.

Epilepsy is a brain disorder that causes people to have recurring seizures and convulsions. Seizures occur due to a temporary failure in the brain's electrical activity. Normally, brain cells coordinate body movements by sending signals through muscle nerves in an orderly organized manner. In epilepsy, brain cells send too many signals in a disordered manner. The result can be uncoordinated muscle activity known as an epileptic seizure.

Oxcarbazepine is used to treat partial epileptic seizures with or without secondary generalization with tonic-clonic seizures. Partial seizures involve a limited area of the brain but can spread to the entire brain and produce generalized tonic-clonic seizures. There are 2 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.

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

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

If you have any doubts about how oxcarbazepine works or why you have been prescribed this medicine, ask your doctor.

2. What you need to know before you take oxcarbazepine cinfa

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

Monitoring during treatment with oxcarbazepine

Before and during treatment with oxcarbazepine, your doctor may perform a blood test to establish your dose. Your doctor will tell you when to have the tests.

Do not take oxcarbazepine cinfa

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

If you are allergic, inform your doctor before taking oxcarbazepine. If you think you are allergic, ask your doctor.

Warnings and precautions

Consult your doctor or pharmacist before starting to take oxcarbazepine cinfa

• if you have ever suffered any unusual allergic reaction(rash or any other type of allergy) to carbamazepine or any other medicine. If you are allergic to carbamazepine, the chances of you being allergic to oxcarbazepine are 1 in 4 (25%).
• if you have kidney disease.
• if you have severe liver disease.
• if you are taking diuretics(medicines to help the kidneys eliminate salt and water by increasing the amount of urine produced).
• if you have heart disease, shortness of breath and/or swelling of feet or legs due to fluid retention.
• if you know that your sodium level in the blood is lowas shown by your blood test (see section 4).
• if you are a woman taking oral contraceptives (such as the pill), oxcarbazepine may make the contraceptive not work. Use a non-hormonal contraceptive method or an extra one while taking oxcarbazepine. This can help prevent an unwanted pregnancy. Inform your doctor immediately if you have irregular vaginal bleeding or spotting. If you have any doubts about this, consult your doctor or healthcare professional before taking oxcarbazepine.

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

If you notice any of the following symptoms after taking oxcarbazepine, inform your doctor immediately or go to the Emergency Department of the nearest hospital:

• if during treatment you suffer an allergic reaction. The symptoms include swelling of the lips, eyelids, face, throat, mouth, or sudden respiratory problems, as well as fever with swelling of the lymph nodes, rash, or blisters on the skin (see section 4).
• if you notice symptoms suggesting hepatitis, such as jaundice (yellowing of the skin or the white of the eyes).
• if you notice an increase in the frequency of seizures. This is especially important in children, but it can also occur in adults.
• if you notice possible symptoms of blood disorderssuch as fatigue, shortness of breath when exercising, paleness, headache, chills, dizziness, frequent infections with fever, sore throat, mouth ulcers, bleeding or bruising more frequently than usual, nosebleeds, reddish or purplish spots, or spontaneous appearance of spots on the skin.
• a small number of people treated with antiepileptics like oxcarbazepine have had thoughts of self-harm or suicide. If at any time you experience these thoughts, contact your doctor immediately.
• if you notice that your heart rate is fast or unusually slow.

Children and adolescents

For treatment in children, your doctor may recommend monitoring thyroid function before and during treatment.

Other medicines and oxcarbazepine cinfa

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

Especially in the case of:

• Oral contraceptives such as the pill (see section "Warnings and precautions").
• Other antiepileptic medicines and enzyme-inducing medicines such as carbamazepine, phenobarbital, phenytoin, lamotrigine, and rifampicin.
• Medicines that reduce sodium levels in the blood, such as diuretics (used to help the kidneys eliminate salt and water by increasing urine production), desmopressin, and non-steroidal anti-inflammatory medicines such as indomethacin.
• Lithium and monoamine oxidase inhibitors (medicines used to treat mood disorders and some types of depression).
• Medicines that control the body's immune system such as cyclosporin and tacrolimus.

Taking oxcarbazepine cinfa with food, drinks, and alcohol

Oxcarbazepine can be taken with or without food. During treatment with oxcarbazepine, avoid taking alcoholic beverages, as it may increase the sedative effects of this medicine; if in doubt, consult your doctor.

Pregnancy, breastfeeding, and fertility

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

Pregnancy

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 entirely 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 negatively, 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 during pregnancy, your child may have a low birth weight and weigh less than expected at birth [small size for gestational age (SGA)]. Among women with epilepsy, in one study, around 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 around 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.

Breastfeeding

If you are taking this medicine, ask your doctor before starting breastfeeding. The active substance of oxcarbazepine cinfa passes into breast milk. Although the available data suggest that the amount of oxcarbazepine cinfa that passes to the breastfed child is low, a risk of side effects in the baby cannot be ruled out.

Your doctor will inform you of the benefits and potential risks of breastfeeding while using oxcarbazepine cinfa. If you are breastfeeding during treatment with oxcarbazepine cinfa and think your baby is experiencing any side 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 reduce your reaction ability. These effects, as well as the disease itself, may impair your ability 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 cinfa

How much to take

Use in adults

• The recommended dose for adults (including elderly patients) is 600 mg per day.
• Take a dose of 300 mg twice a day.
• If necessary, your doctor may gradually increase this dose until the best dose for you is achieved. The best results are usually obtained with doses between 600 and 2,400 mg per day.
• The dose is the same if oxcarbazepine is taken with another antiepileptic medicine.
• If you have kidney problems(renal insufficiency), the initial dose is half the normal initial dose.
• If you have severe liver disease, your doctor will adjust the dose.

Use in children

Oxcarbazepine can be used in children aged 6 years and above.

The recommended dose for children is calculated based on weight.

• The initial dose is 8 to 10 milligrams per kilogram 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.
• Your doctor may gradually increase the dose until the best dose for your child is achieved. The best results are usually obtained with doses of 30 milligrams per kilogram of body weight per day. The maximum dose for a child is 46 milligrams per kilogram of body weight per day.

How to take oxcarbazepine cinfa

• The tablets can be swallowed with a little water.
• If necessary, the tablets can be broken into two halves to facilitate administration. The score line is only for breaking the tablet if you find it difficult to swallow it whole.

When and for how long to take oxcarbazepine cinfa

Take oxcarbazepine twice a day, every day, approximately at the same time of day, unless your doctor tells you otherwise. This will have the best effect for controlling epilepsy. It will also help you remember when to take the tablet or tablets.

Your doctor will inform you how long your treatment or your child's treatment will last. The duration of treatment will depend on the type of seizures you or your child suffer from. You may need to continue treatment for several years to control epileptic seizures. Do not change the dose or stop treatment without talking to your doctor first.

If you take more oxcarbazepine cinfa than you should
