Patient leaflet - Levetiracetam Tillomed 100 mg/ml oral solution
1. What Levetiracetam is and what it is used for
Levetiracetam Tillomed 100 mg/ml oral solution (hereinafter referred to as Levetiracetam) is an antiepileptic medicine (a medicine used to treat seizures in epilepsy).
Levetiracetam 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:
o partial onset seizures with or without generalisation in adults,
adolescents, children and infants from one month of age
o 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
o 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).
2. What you need to know before you take Levetiracetam
Do not take Levetiracetam
- 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 taking Levetiracetam:
- If you suffer from kidney problems, follow your doctor’s instructions. They 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 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.
Children and adolescents
- Levetiracetam is not indicated in children and adolescents below 16 years on its own (monotherapy).
Other medicines and Levetiracetam
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including those obtained without a prescription. This includes herbal medicines.
Do not take macrogol (a medicine used as a laxative) for one hour before and one hour after taking levetiracetam as this may result 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.
Pregnancy
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. Two studies do not suggest an increased risk of autism or intellectual disability in children born to mothers treated with levetiracetam during pregnancy. However, the available data regarding the impact of levetiracetam on neurodevelopment in children is limited.
Breast-feeding
Breast-feeding is not recommended during treatment.
Driving and using machines
Levetiracetam 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 contains methyl parahydroxybenzoate (E128), propyl parahydroxybenzoate (E216) and maltitol
Levetiracetam oral solution contains methyl parahydroxybenzoate (E218) and propyl parahydroxybenzoate (E216) which may cause allergic reactions (possibly delayed).
Levetiracetam oral solution also contains maltitol. If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicinal product.
