Oxcarbazepine is available as a tablet taken by mouth. It may be taken with or without food, according to the instructions provided by your healthcare provider.
Try to take each dose at approximately the same time every day. Maintaining a regular schedule helps keep a steady amount of medication in your body and may improve seizure control.
Swallow the tablet with water. Do not change how you take the medication, split the tablet, or crush it unless your doctor or pharmacist confirms that it is safe to do so.
Starting Treatment
To reduce the risk of side effects, your healthcare provider may start you on a low dose of oxcarbazepine and gradually increase it over time. This process is called dose titration.
Increasing the dose slowly allows your body time to adjust to the medication. It also helps your healthcare provider find the lowest dose that provides effective seizure control with manageable side effects.
Follow the dosing schedule carefully. Do not increase or decrease your dose on your own, even if your seizures continue or you experience side effects.
Factors That Affect the Dose
The appropriate dose of Trileptal depends on several factors, including:
- The type and frequency of seizures
- Your age and body weight
- Your kidney function
- Your response to treatment
- Side effects you experience
- Whether Trileptal is used alone or with other seizure medications
- Other prescription and non-prescription products you take
Your healthcare provider may adjust your dose based on how well your seizures are controlled and how your body responds to the medication.
Adult Dosage
For many adults, the starting dose of Trileptal is 300 mg twice daily, for a total of 600 mg per day.
The dose may be gradually increased at intervals determined by the healthcare provider. Some adults may require higher doses to achieve adequate seizure control.
Depending on the treatment plan, the maximum recommended dose may be up to 2,400 mg per day. Higher doses may cause more side effects, so patients taking larger amounts may require closer monitoring.
Not every patient will need the maximum dose. The goal is to use the lowest effective dose that controls seizures and is well tolerated.
Dosage for Children
For children, the Trileptal dose is usually based on body weight, age, seizure type, and whether other anti-seizure medications are being used.
The healthcare provider may calculate the dose in milligrams per kilogram of body weight per day. The total daily amount is usually divided into two doses.
The dose may be gradually increased according to the child’s response and tolerance. In some treatment situations, the maximum dose may be up to 60 mg per kilogram of body weight per day.
Children can gain weight as they grow, so the dose may need to be reviewed and adjusted over time. Parents and caregivers should attend scheduled follow-up appointments and give the medication exactly as prescribed.
Taking Trileptal with Other Medications
Tell your doctor and pharmacist about everything you take, including:
- Prescription medications
- Non-prescription medicines
- Vitamins and minerals
- Herbal products
- Other anti-seizure medications
- Hormonal birth control
Some medicines may affect how oxcarbazepine works, and oxcarbazepine may change the effects of other medications.
For example, oxcarbazepine may reduce the effectiveness of certain hormonal contraceptives. Patients using birth-control pills, patches, implants, or other hormonal methods should discuss reliable contraception options with their healthcare provider.
Importance of Regular Use
Take Trileptal regularly, even when you feel well or have not experienced a seizure recently. Missing doses may reduce the amount of medication in your body and increase the risk of breakthrough seizures.
Do not stop taking oxcarbazepine suddenly. Abruptly stopping an anti-seizure medication may cause seizures to return, become more frequent, or become more severe. If treatment needs to be stopped, the healthcare provider will usually reduce the dose gradually.
If You Miss a Dose
Take the missed dose as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose and continue with your regular schedule.
Do not take two doses at the same time to make up for a missed dose. Contact your pharmacist or healthcare provider if you are unsure what to do.
Monitoring During Treatment
Your healthcare provider may schedule regular appointments and blood tests while you are taking Trileptal. Monitoring may include:
- Seizure frequency and severity
- Side effects
- Sodium levels in the blood
- Kidney function
- Changes in mood or behaviour
- The effects of other medications
Oxcarbazepine can sometimes lower sodium levels in the blood. Symptoms may include nausea, headache, unusual tiredness, confusion, weakness, or an increase in seizures. Contact your healthcare provider if these symptoms develop.
Keep a Seizure Record
Keeping a seizure diary can help your healthcare provider determine whether the medication is working. Record details such as:
- The date and time of each seizure
- How long the seizure lasted
- Symptoms that occurred
- Possible triggers
- Missed doses
- Side effects
- Recovery time after the seizure
This information may help your healthcare provider decide whether the dose or treatment plan needs to be adjusted.
Important Reminder
Always take the exact dose prescribed for you. Do not take more medication, take it more often, or use it longer than directed. Contact your healthcare provider if your seizures become more frequent, your symptoms worsen, or you experience side effects that are difficult to manage.
