1. What Keppra is and what it is used for

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

Keppra is used:

• as monotherapy in adults and adolescents 16 years of age or older with newly diagnosed epilepsy to treat a type of epilepsy. Epilepsy is a condition in which patients have seizures. Levetiracetam is used for the type of epilepsy in which seizures initially affect only one side of the brain but may then spread to broader areas on both sides of the brain (partial-onset seizures with or without secondary generalization). Your doctor has prescribed levetiracetam to reduce the number of seizures.

• in combination with other antiepileptic medicines to treat:

• partial-onset seizures with or without generalization in adults, adolescents, children, and infants from 1 month of age.

• myoclonic seizures (brief, shock-like jerks of a muscle or group of muscles) in adults and adolescents 12 years of age and older with juvenile myoclonic epilepsy.

• primary generalized tonic-clonic seizures (major seizures, including loss of consciousness) in adults and adolescents 12 years of age and older with idiopathic generalized epilepsy (a type of epilepsy thought to have a genetic cause).

2. What you need to know before taking Keppra

Do not take Keppra

• If you are allergic to levetiracetam, to pyrrolidone derivatives, or to any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Talk to your doctor before starting Keppra

• If you have kidney problems, follow your doctor's instructions, as they will decide whether your dose needs to be adjusted.
• If you notice any growth delay in your child or unexpected development of puberty, contact your doctor.
• A small number of people taking antiepileptic medicines such as Keppra have had thoughts of harming themselves or committing suicide. If you experience any symptoms of depression and/or suicidal thoughts, contact your doctor.
• If you have a personal or family history of irregular heartbeat (visible on electrocardiogram), or if you have a disease and/or are taking treatment that makes you prone to cardiac arrhythmias or electrolyte imbalances.

Inform your doctor or pharmacist if any of the following adverse effects worsen or last longer than a few days:

• Abnormal thoughts, feeling irritable, or reacting more aggressively than usual, or if you or your family and friends notice significant changes in mood or behaviour.
• Worsening of epilepsy:

Rarely, epileptic seizures may worsen or occur more frequently, especially during the first month after starting treatment or increasing the dose.

In a very rare form of early-onset epilepsy (epilepsy associated with SCN8A mutations) causing multiple seizure types and loss of skills, you may notice that seizures persist or worsen during treatment.

If you experience any of these new symptoms while taking Keppra, seek medical advice as soon as possible.

Children and adolescents

• Treatment with Keppra alone (monotherapy) is not indicated in children and adolescents under 16 years of age.

Taking Keppra with other medicines

Inform your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicines.

Do not take macrogol (a medicine used as a laxative) within one hour before or one hour after taking levetiracetam, as it could reduce its effect.

Pregnancy and breastfeeding

If you are pregnant, breastfeeding, think you may be pregnant, or are planning to become pregnant, consult your doctor before using this medicine. Levetiracetam may only be used during pregnancy if, after careful evaluation, your doctor considers it necessary.

Do not stop your treatment without first discussing it with your doctor.

The risk of birth defects in the baby cannot be completely ruled out. Two studies do not suggest an increased risk of autism or intellectual disability in children born to mothers treated with levetiracetam during pregnancy. However, available data on the impact of levetiracetam on infant neurological development are limited.

Breastfeeding is not recommended during treatment.

Driving and using machines

Keppra may affect your ability to drive or operate tools or machinery, as it may cause drowsiness. This is more likely at the beginning of treatment or when the dose is increased. You should not drive or use machinery until you are certain that your ability to perform these activities is not impaired.

Keppra contains methyl parahydroxybenzoate, propyl parahydroxybenzoate, and maltitol

Keppra 100 mg/ml oral solution contains methyl parahydroxybenzoate (E218) and propyl parahydroxybenzoate (E216), which may cause allergic reactions (possibly delayed).

Keppra oral solution also contains maltitol. If your doctor has informed you that you have an intolerance to certain sugars, consult your doctor before taking this medicine.

Keppra contains sodium

This medicine contains less than 1 mmol of sodium (23 mg) per ml; therefore, it is essentially “sodium-free”.

3. How to take Keppra

Follow exactly the instructions given by your doctor or pharmacist for taking this medicine. If you are unsure, consult your doctor or pharmacist again.

Keppra should be taken twice daily, once in the morning and once in the evening, approximately at the same time each day.

Administration method:

After measuring the correct dose with the appropriate syringe, Keppra oral solution may be diluted in a glass of water or in a feeding bottle. Keppra may be taken with or without food. After oral administration of levetiracetam, a bitter taste may be noticed.

Instructions on how to use the syringe:

• Open the bottle: press down on the cap and unscrew it counterclockwise (figure 1)

• Follow these steps the first time you take Keppra:

• Separate the oral dosing syringe adapter (figure 2).

• Place the adapter onto the top of the bottle (figure 3). Make sure it is securely in place. There is no need to remove the adapter after use.

• Follow these steps each time you take Keppra:

• Attach the oral dosing syringe to the opening of the adapter (figure 4).

• Turn the bottle upside down (figure 5).

• Hold the bottle upside down with one hand and use the other hand to fill the oral dosing syringe.

• Pull the plunger down to fill the oral dosing syringe with a small amount of solution (figure 5A).

• Then, push the plunger up to remove any possible air bubbles (figure 5B).

• Pull the plunger down to the graduation mark on the oral dosing syringe corresponding to the dose in millilitres (ml) prescribed by your doctor (figure 5C). The plunger may move back up within the barrel during the first administration. Therefore, make sure the plunger remains in position until the syringe is disconnected from the bottle.

• Turn the bottle upright (figure 6A). Remove the syringe from the adapter (figure 6B).

• Empty the contents of the syringe into a glass of water or a feeding bottle by pushing the plunger down to the end of the syringe (figure 7).

Duration of treatment:

• Keppra is used as a chronic treatment. You should continue Keppra treatment for the duration indicated by your doctor.
• Do not discontinue your treatment without your doctor's recommendation, as your seizures may increase.

If you take more Keppra than you should

Possible adverse effects of an overdose of Keppra include drowsiness, agitation, aggression, reduced alertness, respiratory depression, and coma.

Contact your doctor if you have taken more oral solution than you should. Your doctor will determine the best treatment for the overdose.

If you forget to take Keppra:

Contact your doctor if you have missed one or more doses.

Do not take a double dose to make up for missed doses.

If you stop taking Keppra:

Stopping Keppra treatment should be done gradually to avoid an increase in seizures. If your doctor decides to discontinue your Keppra treatment, they will provide instructions for the gradual withdrawal of Keppra.

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