1. What Sabrilex is and what it is used for

Sabrilex is used to help control various forms of epilepsy.

It is used in addition to your current medication to treat epilepsy that is "difficult to control". Initially, it will be prescribed by a specialist. Your response to treatment will be monitored.

It is also used to control infantile spasms (West syndrome).

2. What you need to know before you take Sabrilex

Do not take Sabrilex

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

Warnings and precautions

Talk to your doctor before starting Sabrilex if:

• you are breastfeeding
• you are pregnant or planning to become pregnant
• you have had depression or any other psychiatric disorder in the past
• you have had kidney problems
• you have had eye problems.

If you develop symptoms such as drowsiness, decreased consciousness and movement (stupor) or confusion, consult your doctor, who will decide whether to reduce the dose or stop treatment.

A small number of people being treated with antiepileptics such as vigabatrin have had thoughts of harming themselves or committing suicide. If you ever have these thoughts, contact your doctor immediately.

Children

Motor disorders have been reported in children treated for infantile spasms (West syndrome). If you observe unusual movement disorders in the child, consult your doctor, who will decide whether to consider changing treatment.

Taking Sabrilex with other medicines

Please inform your doctor if you are taking clonazepam, as its use in combination with Sabrilex may increase the risk of sedation.

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

Sabrilex should not be taken in combination with other medicines that may have adverse effects on the eyes.

Pregnancy, breastfeeding, and fertility

If you are pregnant, think you may be pregnant, or plan to become pregnant, consult your doctor before using this medicine. Do not take Sabrilex during pregnancy unless your doctor tells you to. Sabrilex may cause problems for the fetus. However, do not stop treatment abruptly, as this may endanger the health of the mother and the baby.

Sabrilex passes into breast milk. If you are breastfeeding, ask your doctor before using this medicine. You should not breastfeed during treatment.

Driving and using machines

Do not drive or operate machinery if your epilepsy is not controlled.

Sabrilex can sometimes cause symptoms such as drowsiness or dizziness, and your ability to concentrate and react may be impaired. If these symptoms appear during your treatment with Sabrilex, you should not perform any hazardous tasks such as driving or operating machinery.

Visual disturbances, which can affect your ability to drive or operate machinery, have occurred in some patients taking this medicine. If you want to continue driving, you should be examined regularly (every six months) to rule out visual disturbances, even if you do not notice any changes in your vision.

Sabrilex contains sodium

This medicine contains less than 23 mg of sodium (1 mmol) per tablet; it is essentially "sodium-free".

3. How to take Sabrilex

Follow the instructions for administration of this medicine exactly as indicated by your doctor. In case of doubt, consult your doctor again.

It is important to follow your doctor's instructions exactly. Never change the dose.

The doctor prescribes the dose and adjusts it individually for patients. The recommended dose for starting treatment is 1 g (2 tablets) per day. However, your doctor may increase or decrease the dose depending on your response to treatment; the normal daily dose for adults is 2 to 3 g (4 to 6 tablets). The highest recommended dose is 3 g per day.

If you are an elderly patient and/or have kidney problems, your doctor will prescribe a lower dose.

Use in children

Resistant partial epilepsy

In children, the dose is based on age and weight. The recommended dose for starting treatment is 40 milligrams per kilogram of body weight per day. The following table indicates the number of tablets to be administered to children depending on their body weight. Remember that this is only a guide. The child's doctor will decide whether to prescribe a slightly different dose.

Weight 10-15 kg 0.5-1 g (1-2 tablets)/day

15-30 kg 1-1.5 g (2-3 tablets)/day

30-50 kg 1.5-3 g (3-6 tablets)/day

More than 50 kg 2-3 g (4-6 tablets)/day (adult dose).

Children with infantile spasms (West syndrome)

The recommended starting dose for infants with West syndrome (infantile spasms) is 50 milligrams per kilogram of body weight per day, although sometimes higher doses may be administered.

Method of administration

The route of administration is oral (by mouth).

Always swallow the tablet with at least half a glass of water.

Sabrilex can be taken before or after meals.

The daily dose can be taken as a single dose or divided into two doses.

If you take more Sabrilex than you should

If you or your child accidentally take too many Sabrilex tablets, consult your doctor immediately or go to the emergency department of the nearest hospital, accompanied by this leaflet, or call the Toxicology Information Service. Telephone 91 562 04 20, indicating the medicine and the amount taken.

Possible symptoms of overdose include drowsiness or loss/decreased level of consciousness.

If you forget to take Sabrilex

If you forget to take a dose, take it as soon as you remember. If it is almost time for your next dose, take only one dose. Do not take a double dose to make up for forgotten doses.

If you stop taking Sabrilex

Do not stop taking this medicine without consulting your doctor. If your doctor decides to stop your treatment, they will give you recommendations on how to gradually reduce the dose. Do not stop it abruptly, as this may cause your seizures to return.

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