What it isOxcarbazepinePensa
The active substance of Oxcarbazepine Pensa is oxcarbazepine.
Oxcarbazepine belongs to a group of medicines called anticonvulsants or antiepileptics.
What it is used forOxcarbazepinePensa
Medicines like oxcarbazepine are the standard treatment for epilepsy.
Patients diagnosed with epilepsy have suffered 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 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 "overexcited" nerve cells in the brain under control, thereby suppressing or reducing the frequency of such seizures.
Oxcarbazepine can be used alone or in combination with other antiepileptic medications. Normally, your doctor will try to find the medication that works best for you or your child; however, in severe epilepsy, you may need a combination of two or more medications to control seizures. Oxcarbazepine is indicated for use in adults and children aged 6 years or older.
Follow your doctor's instructions carefully, even if they differ from those stated in this leaflet.

Especially in the case of:
TakingOxcarbazepinePensawith food, drinks, and alcohol

Pregnancy, breastfeeding, and fertility
PregnancyIf you are pregnant or think you may be pregnant or plan to become pregnant, consult your doctor or pharmacist before using this medicine.
It is essential to control seizures during pregnancy. However, there may be a risk to your baby if you take antiepileptic medicines during pregnancy.
Birth weight
If you use oxcarbazepine during pregnancy, your child may have a small size 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.
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 negatively affects the development of brain function (neurodevelopmental development) in children, while in other studies, this effect has not been observed. The possibility that there is an effect on neurodevelopmental development cannot be ruled out.
Your doctor will inform you of the benefits and possible risks of treatment and help you decide whether you should take Oxcarbazepine Pensa.
Do not stop your treatment with oxcarbazepine during pregnancy without consulting your doctor first.
BreastfeedingIf you are taking this medicine, consult your doctor before starting breastfeeding.
The active substance of Oxcarbazepine Pensa passes into breast milk. Although the available data suggest that the amount of Oxcarbazepine Pensa 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 Pensa. If you are breastfeeding during treatment with Oxcarbazepine Pensa 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, can 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.
