1. What Levetiracetam Seacross is and what it is used for

Levetiracetam is an antiepileptic medicine (a medicine used to treat seizures in epilepsy).

Levetiracetam Seacross is used:

  • on its own in adults and adolescents from 16 years of age with newly diagnosed epilepsy, to treat a certain form of epilepsy. Epilepsy is a condition where the patients have repeated fits (seizures). Levetiracetam is used for the epilepsy form in which the fits initially affect only one side of the brain but could thereafter extend to larger areas on both sides of the brain (partial onset seizure with or without secondary generalisation). Levetiracetam has been given to you by your doctor to reduce the number of fits.
  • as an add-on to other antiepileptic medicines to treat:
    • partial onset seizures with or without generalisation in adults, adolescents and children from 4 years of age.
    • myoclonic seizures (short, shock-like jerks of a muscle or group of muscles) in adults and adolescents from 12 years of age with juvenile myoclonic epilepsy.
    • primary generalised tonic-clonic seizures (major fits, including loss of consciousness) in adults and adolescents from 12 years of age with idiopathic generalised epilepsy (the type of epilepsy that is thought to have a genetic cause).

Levetiracetam Seacross concentrate for solution for infusion is an alternative for patients when administration of the antiepileptic oral levetiracetam medicine is temporarily not feasible.

2. What you need to know before you are given Levetiracetam Seacross
Do not use Levetiracetam Seacross
  • If you are allergic to levetiracetam, pyrrolidone derivatives or any of the other ingredients of this medicine (listed in Section 6).

Warnings and precautions

Talk to your doctor before you are given Levetiracetam.

  • If you suffer from kidney problems, follow your doctor’s instructions. He/she may decide if your dose should be adjusted.
  • If you notice any slowdown in the growth or unexpected puberty development of your child, please contact your doctor.
  • A small number of people being treated with anti-epileptics such as Levetiracetam Seacross have had thoughts of harming or killing themselves. If you have any symptoms of depression and/or suicidal ideation, please contact your doctor.
  • If you have a family or medical history of irregular heart rhythm (visible on an electrocardiogram), or if you have a disease and/or take a treatment that make(s) you prone to heartbeat irregularities or salt imbalances.

Tell your doctor or pharmacist if any of the following side effects gets serious or last longer than a few days:

  • Abnormal thoughts, feeling irritable or reacting more aggressively than usually, or if you or your family and friends notice important changes in mood or behaviour.
  • Aggravation of epilepsy
    Your seizures may rarely become worse or happen more often, mainly during the first month after the start of the treatment or increase of the dose.
    In a very rare form of early-onset epilepsy (epilepsy associated with SCN8A mutations) that causes multiple types of seizures and loss of skills you may notice that the seizures remain present or are becoming worse during your treatment.

If you experience any of these new symptoms while taking Levetiracetam Seacross, see a doctor as soon as possible.

Children and adolescents
  • Levetiracetam Seacross is not indicated in children and adolescents below 16 years on its own (monotherapy)

Other medicines and Levetiracetam Seacross

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including medicines obtained without a prescription.

Do not take macrogol (a drug used as laxative) for one hour before and one hour after taking levetiracetam as this may results in a reduction of its effect.

Pregnancy and breast-feeding

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor for advice before taking this medicine. Levetiracetam can be used during pregnancy, only if after careful assessment it is considered necessary by your doctor.

You should not stop your treatment without discussing this with your doctor.

A risk of birth defects for your unborn child cannot be completely excluded.

Breast-feeding is not recommended during treatment.

Driving and using machines

Levetiracetam Seacross may impair your ability to drive or operate any tools or machinery, as it may make you feel sleepy. This is more likely at the beginning of treatment or after an increase in the dose. You should not drive or use machines until it is established that your ability to perform such activities is not affected.

Levetiracetam Seacross contains sodium

One maximum single dose of Levetiracetam Seacross concentrate contains 2.5 mmol (or 57 mg) of sodium (0.8 mmol (or 19 mg) of sodium per vial). This should be taken into consideration if you are on a controlled sodium diet.

3. How Levetiracetam Seacross is given

A doctor or a nurse will administer you Levetiracetam Seacross as an intravenous infusion. Levetiracetam Seacross must be administered twice a day, once in the morning and once in the evening, at about the same time each day.

The intravenous formulation is an alternative to your oral administration. You can switch from the film-coated tablets or from the oral solution to the intravenous formulation or reverse directly without dose adaptation. Your total daily dose and frequency of administration remain identical.

Adjunctive therapy and Monotherapy (from 16 years of age).

Adults (≥18 years) and adolescents (12 to 17 years) weighing 50 kg or more:

Recommended dose: between 1,000 mg and 3,000 mg each day.

When you will first start taking Levetiracetam Seacross, your doctor will prescribe you a lower dose during 2 weeks before giving you the lowest daily dose.

Dose in children (4 to 11 years) and adolescents (12 to 17 years) weighing less than 50 kg:

Recommended dose: between 20 mg per kg bodyweight and 60 mg per kg bodyweight each day.

Method and route of administration:

Levetiracetam Seacross is for intravenous use.

The recommended dose must be diluted in at least 100 ml of a compatible diluent and infused over 15- minutes.

For doctors and nurses, more detailed direction for the proper use of Levetiracetam Seacross is provided in section 6.

Duration of treatment:

There is no experience with administration of intravenous levetiracetam for a longer period than 4 days.

If you stop using Levetiracetam Seacross:

If stopping treatment, as with other antiepileptic medicines, Levetiracetam Seacross should be discontinued gradually to avoid an increase of seizures. Should your doctor decide to stop your Levetiracetam Seacross treatment, he/she will instruct you about the gradual withdrawal of Levetiracetam Seacross.

If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
