1. What Levetiracetam Crescent is and what it is used for
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:
- partial onset seizures with or without generalisation in adults, adolescents, children and infants from one
month 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).

2. What you need to know before you take Levetiracetam Crescent
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. He/she may decide if your dose should
be adjusted.
• If you notice any slow down 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.
Children and adolescents

Levetiracetam is not indicated in children and adolescents below 16 years on its own (monotherapy).
Other medicines and Levetiracetam Crescent

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.
Do not take macrogol (a drug 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.
Levetiracetam should not be used during pregnancy unless clearly necessary. A risk of birth defects for your
unborn child cannot be completely excluded. Levetiracetam has shown unwanted reproductive effects in animal
studies at dose levels higher than you would need to control your seizures.
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, propyl parahydroxybenzoate and maltitol

Levetiracetam oral solution includes methyl parahydroxybenzoate (E218) and propyl parahydroxybenzoate
(E216) which may cause allergic reactions (possibly delayed).
