What Trileptal is
The active ingredient of Trileptal is oxcarbazepine.
Trileptal belongs to a group of medicines called anticonvulsants or

What Trileptal is used for
Medicines such as Trileptal 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.
Trileptal 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, patients
consciousness is altered.
Trileptal works by keeping the brain’s ‘overexcitable’ nerve cells under
control. This suppresses or reduces the frequency of such seizures.
Trileptal can be used alone or in combination with other antiepileptic
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

Monitoring during your treatment with Trileptal

sore throat, mouth ulcers, bleeding or bruising more easily than
normal, nose bleeds, reddish or purplish patches, or unexplained
blotches on the skin.
a small number of people being treated with antiepileptics such as
Trileptal have had thoughts of harming or killing themselves. If at
any time you have these thoughts, immediately contact your
if you have a fast or unusually slow heart beat.

Before and during your treatment with Trileptal, your doctor may
perform blood tests to determine the dose for you. Your doctor will tell
you when to have the tests.

Do not take Trileptal

In children, your doctor may recommend thyroid function monitoring
before therapy and during therapy.

if you are allergic (hypersensitive) to oxcarbazepine or any other
ingredients of Trileptal tablets (listed in section 6 Further
If this applies to you, tell your doctor before taking Trileptal. If you
think you may be allergic, ask your doctor for advice.

Warnings and precautions
If any of the following apply to you, tell your doctor before you
take Trileptal:
 if you have ever shown unusual sensitivity (rash or any other
signs of allergy) to carbamazepine or to any other medicines. If
you are allergic to carbamazepine, the chances are approximately
1 in 4 (25 %) that you could also have an allergic reaction to
oxcarbazepine (Trileptal).
 if you have kidney disease.
 if you have serious liver disease.
 if you are taking diuretics (medicines used to help the kidneys
get rid of salt and water by increasing the amount of urine
 if you have heart disease, shortness of breath and/or swelling of
the feet or legs due to fluid build-up.
 if your blood level of sodium is low as shown by blood tests
(see section 4 Possible side effects).
 if you are a woman taking a hormonal contraceptive (such as
‘the birth-control pill’) Trileptal may stop your contraceptive from
working. Use a different or extra (non-hormonal) method of
contraception while taking Trileptal. This should help to prevent an
unwanted pregnancy. Tell your doctor immediately if you get
irregular vaginal bleeding or spotting. If you have any questions
about this, ask your doctor or health professional.
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.
If you develop any of the following symptoms after starting
Trileptal, tell your doctor immediately or go to the emergency
department at your nearest hospital:
 if you experience an allergic reaction after starting Trileptal.
Symptoms include swelling of lips, eyelids, face, throat, mouth, or
sudden breathing problems, fever with swollen glands, rash or
skin blistering.
 if you notice symptoms of hepatitis, such as jaundice (yellowing
of skin or the whites of the eyes).
 if you experience an increase in the frequency of seizures. This is
particularly important for children but may also occur in adults.
 if you notice possible symptoms of blood disorders such as
tiredness, being short of breath when exercising, looking pale,
headache, chills, dizziness, frequent infections leading to fever,

This applies especially to:

Hormonal contraceptives, such as the pill (see Take special care
with Trileptal).
Other antiepileptic medicines, such as carbamazepine,
phenobarbital, phenytoin or lamotrigine.
Medicines that reduce the level of sodium in your blood, such as
diuretics (used to help the kidneys get rid of salt and water by
increasing the amount of urine produced), desmopressin and nonsteroidal anti-inflammatory drugs, such as indometacin.
Lithium and monoamine oxidase inhibitors (medicines used to
treat mood swings and some types of depression).
Medicines that control the body’s immune system, such as
ciclosporin and tacrolimus.

Your doctor will tell you how long your or your child’s treatment with
