KEPPRA is an anti - epileptic medicine (a medicine used to treat seizures in epilepsy). KEPPRA is used in patients who are already taking another anti - epileptic medicine, to treat partial seizures in adults and children over 4 years of age with epilepsy.
1. What KEPPRA is and what it is used for
2. What you need to know before you take KEPPRA
Do not take KEPPRA: Before taking this medicine, you should tell your doctor:
- if you are hypersensitive (allergic) to levetiracetam or to any of the other ingredients of KEPPRA (listed in section 6).
Warnings and precautions:
Take special care with KEPPRA:
- If you suffer from kidney problems, follow your doctor’s instructions. They may decide that your dose should be adjusted.
- If your treatment has to be stopped, your doctor will tell you how to withdraw it gradually.
- KEPPRA has not been approved for children below the age of 4 years.
- If you notice any slowing down in the growth or unexpected puberty development of your child, please contact your doctor.
- A small number of people being treated with KEPPRA have had thoughts of harming or killing themselves. If you have, or your child has any symptoms of depression and or thoughts of committing suicide, please contact your doctor.
- If you notice any abnormal and aggressive behaviours, or if you or your family and friends notice important changes in mood or behaviour, immediately contact your doctor.
- if you have a family or medical history of heart problems, for example disturbance in heart rhythm (visible on an electrocardiogram) or if you are taking any other medicine that makes you prone to have disturbance in heart rhythm or unusual amount of salt in the body.
- Your seizures may rarely become worse or happen more often, mainly during the first month after starting the treatment or increase of the dose of KEPPRA. If you notice any of these symptoms while taking KEPPRA, immediately contact your doctor.
- 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.
Other medicines and KEPPRA:
If you are taking other medicines on a regular basis, including complementary or traditional medicines, the use of KEPPRA with these medicines may cause undesirable interactions. Please consult your doctor, pharmacist or other healthcare professional for advice. Don't take macrogol (a medicine used as laxative) for one hour before and one hour after taking KEPPRA as this may results in a loss of its effect. You will be closely monitored if you are taking KEPPRA with:
- methotrexate (used to treat certain types of cancer).
Some other medicines may affect how KEPPRA works or make it more likely that you’ll have side effects. KEPPRA can also affect how some other medicines work. These include:
- probenecid (used to treat gout).
Tell your doctor or pharmacist if you are taking any of these.
Taking KEPPRA with food and drink and alcohol:
You may take KEPPRA with or without food. Caution is advised if alcohol is taken at the same time as KEPPRA.
3. How to take KEPPRA
Do not share medicines prescribed for you with any other person. Always take KEPPRA exactly as your doctor has told you. You should check with your doctor, pharmacist or other healthcare professional if you are unsure. If you think that the effect of KEPPRA is too strong or too weak, talk to your doctor or pharmacist.
Tablets are also available for adults and adolescents that can swallow tablets. The oral solution should be diluted in a glass of water and may be taken with or without food. After oral administration the bitter taste of levetiracetam may be experienced. A graduated oral syringe and instructions for use in the patient information leaflet are provided with the oral solution. The daily dose is administered in two equal divided doses.
Adults (> 18 years) and adolescents (12 to 17 years): As adjunctive therapy, the initial therapeutic dose is 500 mg twice daily. Depending upon the clinical response and tolerance, the daily dose can be increased up to 1 500 mg twice daily. Dose changes can be made in 500 mg twice daily increments or decrements every two to four weeks. The maximum daily dose is 3 000 mg.
Recommended dosage for children and adolescents with normal renal function.
- Weight Starting dose 10 mg/kg twice daily Maximum dose 30 mg/kg twice daily
15 kg (1) 150 mg (1,5 ml) twice daily 450 mg (4,5 ml) twice daily
20 kg (1) 200 mg (2 ml) twice daily 600 mg (6 ml) twice daily
25 kg 250 mg (2.5 ml) twice daily 750 mg (7,5 ml) twice daily
From 50 kg (2) 500 mg twice daily 1 500 mg twice daily
(1) Children 20 kg or less should preferably start treatment with KEPPRA 100 mg/ml oral solution.
(2) Dosage in children and adolescents 50 kg or more is the same as in adults.
The graduated syringe contains up to 1 000 mg levetiracetam (corresponding to 10 ml) with a graduation every 25 mg (corresponding to 0,25 ml).
Elderly (65 years and older): Adjustment of the dose is recommended in elderly patients with compromised renal function (see ‘Patients with renal impairment’ below).
Children aged 4 to 11 years: The initial dose is 10 mg/kg twice daily. Depending upon the clinical response as determined by your doctor, and how well you tolerate KEPPRA, the daily dose can be increased up to 30 mg/kg twice daily. Dose changes can be made in 10 mg/kg twice daily increments or decrements every two weeks. Dosage in children 50 kg or greater is the same as in adults. Your doctor, pharmacist or other healthcare professional may start you on a lower dose of KEPPRA and increase it as your body gets used to the medicine. You should follow their instructions carefully. Tell your doctor, pharmacist or other healthcare professional if your seizures get worse or if you have any new types of seizures.
Administration:
KEPPRA oral solution has to be diluted in a glass of water.
Instruction for use:
- Open the bottle: press the cap and turn it anticlockwise (figure 1).
- Insert the syringe adaptor into the bottle neck (figure 3). Ensure it is well fixed
- Take the syringe and put it in the adaptor opening (figure 4).
- Turn the bottle upside down (figure 5).
- Fill the syringe with a small amount of liquid by pulling the piston down (figure 5A), then push the piston upward in order to remove any possible bubble (figure 5B), finally pull the piston down to the graduation mark corresponding to the quantity in milligrams (mg) prescribed by your doctor (figure 5C).
- Turn the bottle the right way up (figure 6). Remove the syringe from the adaptor (figure 6A).
- Empty the contents of the syringe in a glass of water by pushing the piston to the bottom (figure 7).
- Drink the whole contents of the glass.
- Wash the syringe in water (figure 8).
- Close the bottle with the plastic screw cap.
Duration of treatment: KEPPRA is used as a chronic treatment. You should continue KEPPRA treatment for as long as your doctor has told you.
If you take more KEPPRA than you should: Talk to your doctor or pharmacist immediately. If neither is available, seek help at the nearest hospital or poison control centre. Signs of taking too much KEPPRA are increased sleepiness, anxiety, decreased consciousness and difficulty breathing.
If you forget to take KEPPRA: Do not take a double dose to make up for forgotten dose. Speak to your doctor, pharmacist or other healthcare professional about what to do if you miss a dose.
If you stop taking KEPPRA: Do not stop treatment without your doctor’s advice as this could increase your seizures. Should your doctor decide to discontinue your KEPPRA treatment, they will instruct you about the gradual withdrawal of KEPPRA.

5. How to store KEPPRA
Keep all medicines out of the reach and sight of children. Due to sensitivity to light, store in the original container. Store at or below 30 °C. Do not use after the expiry date stated on the label. Medicines should not be disposed of via wastewater or household waste. Ask your pharmacist how to dispose of medicines no longer required. These measures will help to protect the environment.
