Oxcarbazepine Umedica contains the active substance oxcarbazepine.
Oxcarbazepine Umedica belongs to a group of medicines called anticonvulsants or antiepileptics.
Medicines such as oxcarbazepine are the standard treatment for epilepsy.
Epilepsy is a brain disorder that causes people to have recurring seizures and convulsions. Seizures happen because of a temporary fault in the brain’s electrical activity. Normally brain cells coordinate body movements by sending out signals through the nerves to the muscles in an organised, orderly way. In epilepsy, brain cells send out too many signals in a disorderly fashion. The result can be uncoordinated muscular activity that is called an epileptic seizure.
Oxcarbazepine is used to treat partial seizures with or without secondarily generalised tonic-clonic seizures. Partial seizures involve a limited area of the brain, but may spread to the whole brain and may cause a generalised tonic- clonic seizure. There are two types of partial seizures: simple and complex. In simple partial seizures, the patient remains conscious, whereas in complex partial seizures, patient’s consciousness is altered.
Oxcarbazepine works by keeping the brain’s “overexcitable” nerve cells under control. This suppresses or reduces the frequency of such seizures.
Oxcarbazepine can be used alone or in combination with other antiepileptic medicines.
Usually, the doctor will try to find the one medicine that works best for you or for your child. However, with more severe epilepsy, a combination of two or more medicines may be needed to control seizures. Oxcarbazepine is for use in adults and in children of 6 years of age and above.
If you have any questions about how oxcarbazepine works or why this medicine has been prescribed for you, ask your doctor.
Follow all your doctor’s instructions carefully, even if they differ from the general information contained in this leaflet.
Before and during your treatment with oxcarbazepine, your doctor may perform blood tests to determine the dose for you. Your doctor will tell you when to have the tests.
If this applies to you, tell your doctor before taking oxcarbazepine. If you think you may be allergic, ask your doctor for advice.
Talk to your doctor or pharmacist before taking oxcarbazepine:
The risk of serious skin reactions in patients of Han Chinese or Thai origin associated with carbamazepine or chemically -related compounds may be predicted by testing a blood sample of these patients. Your doctor should be able to advise if a blood test is necessary before taking oxcarbazepine.
In children, your doctor may recommend thyroid function monitoring before therapy and during therapy.
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.
This applies especially to:
Oxcarbazepine can be taken with or without food.
Alcohol may increase the sedative effects of oxcarbazepine. Avoid alcohol as much as possible and ask your doctor for advice.
Pregnancy
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.
It is important to control epileptic seizures during pregnancy. However, there may be a risk to your baby if you take antiepileptic medicines during pregnancy.
Birth defects
Studies have not shown an increased risk of birth defects associated with oxcarbazepine use during pregnancy, however, a risk of birth defects for your unborn child cannot be completely ruled out.
Neurodevelopmental disorders
Some studies have shown that exposure to oxcarbazepine in the womb negatively affects the development of brain function (neurodevelopment) in children, while other studies have not found such an effect. The possibility of an effect on neurodevelopment cannot be ruled out.
Birth weight
If you use oxcarbazepine during pregnancy, your child may be smaller and weigh less than expected at birth [born small for gestational age (SGA)]. Among women with epilepsy, in one study, around 15 out of every 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 every 100 children born to women not taking anti-seizure medication during pregnancy.
Your doctor will tell you the benefits and potential risks involved and help you to decide whether you should take oxcarbazepine.
Do not stop your treatment with oxcarbazepine during pregnancy without first checking with your doctor.
Breast-feeding
If you are taking this medicine, ask your doctor for advice before starting breastfeeding. The active substance in oxcarbazepine passes into breast milk. Although available data suggest that the amount of oxcarbazepine that passes to a breastfed baby is low, a risk of side effects for the baby cannot be ruled out. Your doctor will discuss with you the benefits and potential risks of breastfeeding while taking oxcarbazepine. If you are breastfeeding while taking oxcarbazepine and you think your baby is having side effects such as excessive sleepiness or poor weight gain, tell your doctor immediately.
Oxcarbazepine may make you feel sleepy or dizzy, or may cause blurred vision, double vision, lack of muscle coordination or a depressed level of consciousness, especially when starting treatment or increasing the dose.
It is important to discuss with your doctor whether you can drive a vehicle or operate machines while taking this medicine.
Always take this medicine exactly as your doctor or pharmacist has told you, even if this differs from the information given in this leaflet. Check with your doctor or pharmacist if you are not sure.
Use in adults
Use in children and adolescents
Take oxcarbazepine twice a day, every day, at about the same time of day, unless the doctor tells you otherwise. This will have the best effect on controlling epilepsy. It will also help you to remember when to take the tablet(s).
Your doctor will tell you how long your or your child’s treatment with oxcarbazepine will last. The length of treatment will depend on your or your child’s seizure type. Treatment may be needed for many years to control the seizures. Do not change the dose or stop treatment without talking to your doctor.
If you have taken more tablets than your doctor prescribed, contact the nearest hospital or your doctor immediately. Symptoms of overdose with oxcarbazepine may include:
If you have forgotten one dose, take it as soon as you remember. However, if it is time for your next dose, do not take the missed dose. Go back to your regular dosing timetable. Do not take a double dose to make up for a forgotten dose.
If you are unsure or have forgotten to take several doses, contact your doctor.
Do not stop taking your medicine unless your doctor tells you to.
To prevent sudden worsening of your seizures, never discontinue your medicine abruptly.
If your treatment is stopped, it should be done gradually as instructed by your doctor.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
Like all medicines, this medicine can cause side effects, although not everybody gets them.
