What You Should Know About Oxcarbazepine

What is Oxcarbazepine?

Oxcarbazepine is an anti-epileptic medication which is primarily used to prevent focal (partial) seizures. It's been approved for slightly different uses in children and adults.

For adults:

  • Individual or additional medication for treatment of focal seizures.

For children:

  • Individual medication management for preventing focal seizures in children aged 4–16 years old, or
  • Additional medication therapy for treatment of focal seizures in children aged 2–16 years old.

Focal seizures (partial seizures) are a type of seizure that begins in one area (or “focal point”) of the brain and may spread to other areas. There may or may not be changes to behaviour and awareness, depending on the specific area(s) of the brain involved.

What are Seizures?

Seizures are periods of uncontrolled electrical activity in the brain that lead to a mental and behavioural alterations. This can be dangerous for a number of different reasons. The seizure itself can be dangerous to the function of your brain, and experiencing a loss of control of your body can be dangerous while completing certain activities such as driving and climbing stairs.

Seizures can be very dangerous when left uncontrolled, and medication management is always necessary when someone has been diagnosed with a seizure disorder.

Typical side Effects

There are many possible side effects that you can experience while taking oxcarbazepine. Not everyone will experience any or all of the possible side effects. However, it is important to be aware of the possible changes to your body that may occur following initiation of a new medication. The most commonly experienced side effects of oxcarbazepine include:

  • Dizziness
  • Drowsiness
  • Double vision or nystagmus
  • Fatigue
  • Nausea and vomiting
  • Abnormal vision
  • Headache
  • Tremor

Side effects may be mild, but if you experience any effects that are intolerable it is important to speak with your healthcare provider about whether the medication continues to be right for you.

Serious side effects

While an anti-seizure medication such as oxcarbazepine is essential in order to prevent possibly dangerous seizures from occurring, there are some rare but serious possible dangers from taking this medication.

Blood changes

Sometimes certain components of your blood will decrease during oxcarbazepine therapy. This can include the red blood cells (which carry oxygen) and certain white blood cells (which fight off infection and disease). It is therefore important for blood levels to be monitored throughout your oxcarbazepine treatment.


Some people taking oxcarbazepine have developed hyponatremia (low levels of salt in your body). This can be serious, as our bodies require a certain amount of sodium to carry out essential activities. This generally occurs within 3 months, though it sometimes has been noted more than a year after medication initiation. Sodium levels should therefore be monitored in people at increased risk of altered hyponatremia.

Reactions involving your skin—SJS and TEN

One of the possible dangers of oxcarbazepine is the appearance of serious skin conditions, such as Stevens-Johnson syndrome (SJS) or toxic epidermal necrolysis (TEN). These skin conditions usually present first with a rash as well as with flu-like symptoms such as a fever. SJS and TEN are serious and can even be fatal if not caught and treated quickly. Therefore, at any sign of a fever or rash when taking this medication, immediately seek medical attention.

Many medications cannot be taken at the same time as oxcarbazepine. This is usually due to either oxcarbazepine increasing or decreasing the concentration of the other drug in your body, or the other drug increasing or decreasing the concentration of oxcarbazepine in your body. This can be dangerous because it can increase either medication to possibly toxic levels or decrease either medication to ineffective levels in your body. Some of these medications include:

It is therefore important to speak with your healthcare provider about any medications you may be taking when you start oxcarbazepine. The levels of your various medications can then be monitored to ensure the medications remain both effective and safe.

Pregnancy or breastfeeding

Like most anti-seizure medications, there are some risks to the fetus when oxcarbazepine is taken during pregnancy. Though there aren’t many well defined studies regarding the safety risks of oxcarbazepine, it has been noted that there are more malformations associated with children born from mothers taking this medication. This includes cleft lip, cleft palate, Down’s syndrome, hip dysplasia, and other congenital malformations.

That being said, if you are taking oxcarbazepine and your seizures are well controlled, it can also be risky to stop this medication. Therefore, if you become pregnant while taking oxcarbazepine it is essential to speak with your healthcare provider about the risk of malformations to your fetus versus the risk of being removed from effective anti-seizure medications.

Can I stop taking oxcarbazepine if I don’t feel like I need it anymore?

No! It is very important NOT to suddenly stop taking your oxcarbazepine medication. If there is an issue with your medication management, it is essential to speak with your healthcare provider and discuss your options with them. If you have been diagnosed with epilepsy it is likely that you should be on anti-seizure medications for life, so it is important to find one that works well for you.

If you are instructed by your healthcare provider to stop taking oxcarbazepine, this also must not be done abruptly. Suddenly stopping this medication can actually increase the risk of experiencing a seizure, so it is important to be withdrawn from the medication slowly and carefully.
