1. What is Levebon and what is it used for

Levebon, coated tablets is an antiepileptic medicine (a medicine used to treat seizures in epilepsy).
Levebon is used:

• as the only medicine in adults and adolescents from 16 years of age with newly diagnosed epilepsy, for the treatment of certain types of epilepsy. Levetiracetam is used to treat a type of epilepsy in which seizures initially affect only one half of the brain, but may later spread to larger areas of both brain hemispheres (partial seizures with or without secondary generalization). The doctor has prescribed levetiracetam to reduce the number of seizures.
• as an additional antiepileptic medicine for the treatment of:
• partial seizures with or without secondary generalization in adults, children, and infants from 1 month of age,
• myoclonic seizures (short, shock-like muscle contractions) in adults and adolescents from 12 years of age with juvenile myoclonic epilepsy,
• primary generalized tonic-clonic seizures (large seizures, including loss of consciousness) in adults and adolescents from 12 years of age with idiopathic generalized epilepsy (a type of epilepsy that is likely to have genetic causes).

2. Important information before taking Levebon

When not to take Levebon

• If the patient is allergic to levetiracetam, pyrrolidine derivatives, or any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Before starting treatment with Levebon, the patient should consult a doctor:

• If the patient has kidney disease, they should strictly follow the doctor's instructions, who may decide to adjust the dose.
• If slowing of growth or unexpected premature puberty is observed in a child taking the medicine, the patient or their caregiver should contact a doctor.
• In a small number of patients treated with antiepileptic medicines, such as Levebon, thoughts of self-harm or suicidal thoughts have occurred. In case of symptoms of depression and/or suicidal thoughts, the patient should contact a doctor.
• If the patient or their family members have a history of heart rhythm disorders (visible on an ECG) or if the patient has a disease and/or is taking medicines that may cause heart rhythm disorders or if the patient has electrolyte disturbances.

The patient should inform their doctor or pharmacist if any of the following undesirable effects worsen or persist for more than a few days:

• Abnormal thoughts, irritability, or more aggressive reactions than usual, which may be significant changes in mood or behavior noticed by the patient or their family and friends.
• Worsening of epilepsy. Seizures may rarely worsen or occur more frequently, mainly during the first month of treatment or after a dose increase. If any of these new symptoms occur while taking Levebon, the patient should contact their doctor as soon as possible. In a very rare form of epilepsy with an early onset (epilepsy associated with mutations in the SCN8A gene) causing various types of seizures and loss of skills, the patient may notice that seizures continue to occur or worsen during treatment.

Children and adolescents

Levebon should not be used as the only medicine (monotherapy) in children and adolescents under 16 years of age.

Levebon and other medicines

The patient should tell their doctor or pharmacist about all medicines they are currently taking or have recently taken, as well as any medicines they plan to take.
The patient should not take macrogol (a medicine used as a laxative) one hour before and one hour after taking levetiracetam, as it may cause a lack of effect.

Pregnancy and breastfeeding

If the patient is pregnant or breastfeeding, thinks they may be pregnant, or plans to have a child, they should consult a doctor before taking this medicine.
Levetiracetam may be used during pregnancy only if the doctor considers it necessary after careful evaluation.
The patient should not stop treatment without discussing it with their doctor, as it may cause an increase in the frequency of seizures.
The patient should not breastfeed while taking Levebon.

Driving and using machines

Levebon may affect the patient's ability to drive and use machines, as it may cause drowsiness. This is more likely at the beginning of treatment or after a dose increase. The patient should not drive or use machines until the effect of the medicine on their ability to perform these activities has been established.

3. How to take Levebon

This medicine should always be taken as directed by the doctor. In case of doubts, the patient should consult a doctor or pharmacist.
The patient should take the number of tablets as directed by the doctor.
Levebon should be taken twice a day, in the morning and evening, at approximately the same time every day.
Supportive therapy and monotherapy (from 16 years of age)

Adults (≥ 18 years) and adolescents (12-17 years) with a body weight of 50 kg or more:

Usual dose: between 1000 mg and 3000 mg per day.
If the patient is taking Levebon for the first time, the doctor may prescribe a lower dose for the first two weeks, and then the usual dose.
Example: if the daily dose is 1000 mg, the initial reduced dose is ½ tablet of 500 mg in the morning and ½ tablet of 500 mg in the evening, and the dose will be gradually increased to the target dose of 1000 mg per day after two weeks.

Adolescents (12-17 years) with a body weight of 50 kg or less:

The doctor will prescribe the most suitable pharmaceutical form of the medicine, depending on the patient's body weight and dose.

The doctor will prescribe the most suitable form of Levebon, depending on the patient's age, body weight, and dose.
For infants and children under 6 years of age, for children and adolescents (from 6 to 17 years) with a body weight of less than 50 kg, and if the recommended dose cannot be achieved with the available tablet strengths, the most suitable form of the medicine is an oral solution.

Method of administration:

Tablets should be swallowed, washed down with a sufficient amount of liquid (e.g., a glass of water). Levebon can be taken with or without food. After oral administration, levetiracetam may leave a bitter taste.

Duration of treatment:

• Levebon is used for long-term treatment. The patient should continue treatment for as long as the doctor recommends.
• The patient should not stop treatment without consulting a doctor, as it may cause an increase in the frequency of seizures.

Use of a higher than recommended dose of Levebon

Possible undesirable effects after an overdose of Levebon include drowsiness, agitation, aggression, decreased consciousness, respiratory depression, and somnolence.
In case of taking a higher dose of the medicine than recommended, the patient should immediately consult a doctor.
The doctor will recommend the best possible treatment for the overdose.

Missing a dose of Levebon

The patient should contact a doctor if they have missed one or more doses of the medicine.
The patient should not take a double dose to make up for the missed dose.

Stopping treatment with Levebon

If treatment with Levebon is to be stopped, the medicine should be discontinued gradually to avoid an increase in the frequency of epileptic seizures. If the doctor decides to stop treatment, they will also inform the patient how to gradually discontinue the medicine.
