Oxcarbazepine film-coated tablets contain the active ingredient oxcarbazepine. Oxcarbazepine belongs to a group of
medicines called anticonvulsants which are used in the treatment of epilepsy. Oxcarbazepine is designed to help control
seizures or fits in patients that have epilepsy. Oxcarbazepine is used to treat certain types of epilepsy in adults and children
from 6 years old.
Your doctor may prescribe Oxcarbazepine film-coated tablets alone or along with other epilepsy medicine.

Warnings and precautions
Talk to your doctor or pharmacist before taking Oxcarbazepine:
• you are allergic (e.g. have ever developed a rash or other hypersensitivity reaction) to carbamazepine, a similar
anticonvulsant, as there is approximately a 1 in 4 (25%) chance you may be allergic to oxcarbazepine too
• if you develop an inflammation of the liver or a severe skin reaction (see under Possible side effects)
• you have a kidney disease associated with a low level of sodium (salt) in your blood. Oxcarbazepine can lower
the sodium levels in your blood further which may lead to symptoms of sodium shortage (see under Possible side
effects). If you have a kidney disease your doctor may examine your blood before and at regular intervals after
starting treatment with Oxcarbazepine
• you are taking other medicines that can lower sodium levels in the blood (e.g. diuretics, desmopressin and nonif
steroid anti-inflammatory drugs (NSAIDs) such as indometacin and ibuprofen). See under Other medicines and
• you have heart problems such as heart failure (breathlessness and swollen ankles). Your doctor will measure your
weight regularly to make sure that you do not retain water
• you have a heart rhythm disorder
• you are using hormonal contraceptives (see under Other medicines and Oxcarbazepine)
• you have possible signs of a blood disorder such as tiredness, breathlessness when exercising, looking pale,
headache, chills, dizziness, infections leading to fever, sore throat, mouth ulcer, bleeding or bruising more easily than
normal, nose bleeding, reddish or purplish patches, unexplained blotches on skin.
A small number of people being treated with anti-epileptics such as Oxcarbazepine have had thoughts of harming or
killing themselves. If at any time you have these thoughts, immediately contact your doctor.
Potentially life-threatening skin rashes (Stevens-Johnson syndrome, toxic epidermal necrolysis) have been reported with the
use of oxcarbazepine, appearing initially as reddish target-like spots or circular patches often with central blisters on the
Additional signs to look for include ulcers in the mouth, throat, nose, genitals and conjunctivitis (red and swollen eyes).
These potentially life-threatening skin rashes are often accompanied by flu-like symptoms. The rash may progress to
widespread blistering or peeling of the skin.
The highest risk for occurrence of serious skin reactions is within the first weeks of treatment.
If you have developed Stevens-Johnson syndrome or toxic epidermal necrolysis with the use of oxcarbazepine, you must not
be re-started on oxcarbazepine at any time.
If you develop a rash or these skin symptoms, seek immediate advice from a doctor and tell him that you are taking this
Patients of Han Chinese or Thai origin
The risk of serious skin reactions in patients of Han Chinese or Thai origin associated with carbamazepine or chemicallyrelated 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.
Other medicines and Oxcarbazepine
Tell your doctor if you are taking, have recently taken or might take any other medicines, particularly any of the following
medicines as they may interact with Oxcarbazepine:
other anticonvulsant medicines such as phenobarbitone, phenytoin, carbamazepine, lamotrigine and valproic
acid. Your doctor may need to adjust the dosage of these medicines when they are given in combination with
Oxcarbazepine. In combination with lamotrigine there is an increased possibility of side effects like nausea, drowsiness,
dizziness and headache occurring
hormonal contraceptives (like the “pill”). Oxcarbazepine can stop these medicines working properly. Another form of
contraception should also be used
medicines to treat mental illness such as lithium and MAOIs (Monoamine Oxidase Inhibitors), like phenelzine and
moclobemide. Combination with lithium might increase the occurrence of side effects
medicines that can lower sodium levels in the blood (e.g. diuretics, desmopressin and non-steroid anti-inflammatory
drugs such as indometacin and ibuprofen). Oxcarbazepine can lower the sodium levels in your blood further which may
lead to symptoms of sodium shortage (see Possible side effects). Your doctor should examine your blood before and
at regular intervals after starting treatment with Oxcarbazepine
medicines used to control the body’s immune system (immunosuppressants) such as. ciclosporin, tacrolimus)
Oxcarbazepine with food, drink and alcohol
Oxcarbazepine can be taken with or without food.

Pregnancy and breast-feeding
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. Your doctor will tell you the benefits and potential risks involved and help you to
decide whether you should take Oxcarbazepine.
