1. What Sabril is and what it is used for

Sabril is used to help control various forms of epilepsy. It is used together with your current medication to treat “difficult to control” epilepsy. It will initially be prescribed by a specialist. Your response to the treatment will be monitored.

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

2. Before you take Sabril

Do not take Sabril

  • 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 taking Sabril if:

  • You are breast-feeding
  • You are pregnant or plan to become pregnant
  • You have or have had depression or any other psychiatric illness in the past
  • You have had any kidney problems
  • You have had any problems with your eyes

Visual field loss (loss of sight from the edges of your field of vision) may occur during treatment with Sabril. You should discuss this possibility with your doctor before you begin treatment with this medicine. This visual field loss may be severe and irreversible, so it must be found early. A deterioration of this visual field loss after treatment is discontinued cannot be excluded. It is important that you inform your doctor promptly if you become aware of any change to your vision. Your doctor should perform a Visual field examination before you start taking Sabril and at regular intervals during the treatment.

If you develop symptoms like sleepiness, reduced consciousness and movements (stupor) or confusion consult your doctor who will decide upon a dose reduction or withdrawal.

A small number of people being treated with antiepileptics such as vigabatrin have had thoughts of harming or killing themselves. If at any time you have had these thoughts, immediately contact your doctor.

Children

Movement disorders have been seen in young infants treated for infantile spasms (West’s syndrome).If you observe unusual movement disorders in the child, consult your doctor who will decide if it is necessary to consider changing the treatment.

Other medicines and Sabril

Please tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. Sabril should not be used in combination with other medicines that may have side effects related to the eye.

Pregnancy, breast-feeding and fertility

If you are pregnant, think you may be pregnant or are planning to have a baby, ask your doctor for advice before taking this medicine.

Do not take Sabril during pregnancy unless your doctor tells you to. Sabril may cause problems to unborn children. However, do not stop taking the medicine suddenly because this may risk the mother’s health as well as the baby’s health.

Sabril passes into breast milk. If you are breast-feeding, ask your doctor for advice before taking this medicine. Breast-feeding should not be done during treatment.

Driving and using machines

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

Sabril sometimes causes symptoms like drowsiness or dizziness and your ability to concentrate and react may be reduced. If such symptoms occur whilst taking Sabril, you should not do any hazardous tasks such as driving or operating machinery.

Visual disorders, which can affect your ability to drive and use machines, have been found in some patients taking this medicine. If you wish to continue driving you must be tested regularly (every six months) for the presence of visual disorders even if you do not notice any changes to your vision.

3. How to take Sabril

Always take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.

It is important to follow your doctor’s instructions exactly. Never change the dose yourself. The doctor prescribes the dose and adjusts it individually for the patients.

The usual starting dose for adults is 1 g (2 tablets) daily. However, your doctor may wish to increase or decrease the dose depending on your response; the usual adult daily dose is 2 to 3 g (4 to 6 tablets). The highest recommended dose is 3 g/day.

If you are older people and/or have kidney problems, your doctor may wish to give you a smaller dose.

Use in children

Resistant partial epilepsy

For children, the dose is based on age and weight. The usual starting dose for children is 40 milligrams per kilogram bodyweight daily. The following table gives the number of tablets to give to a child according to his/her bodyweight. Remember that this is just a guideline. The child’s doctor may wish to have slightly different doses.

Bodyweight 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

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

Children with infantile spasms (West’s Syndrome)

The recommended starting dose for infants with West’s Syndrome (infantile spasms) is 50 milligrams per kilogram bodyweight per day although higher doses may be used sometimes.

Method of administration

The route of administration is oral use (by mouth).

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

You can take Sabril before or after meals.

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

If you take more Sabril than you should

If you or your child accidentally take too many Sabril tablets, tell your doctor immediately or go to your nearest hospital or Poison Information Centre.

Possible signs of overdose include drowsiness or loss/depressed level of consciousness.

If you forget to take Sabril

If you forget to take a dose, take it as soon as you do remember. If it is almost time for your next dose, just take one dose. Do not take a double dose to make up for the missed dose.

If you stop taking Sabril

Do not stop taking this medicine without talking to your doctor. If your doctor decides to stop your treatment you will be advised to gradually reduce the dose. Do not stop suddenly as this may cause your seizures to occur again.

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