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

There have been reports of movement disorders 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 medications

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

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

Sabrilex should not be taken in combination with other medications that may have adverse effects related to the eyes.

Visual disturbances, which may affect your ability to drive or operate machinery, have appeared in some patients taking this medication. If you wish to continue driving, you must be examined regularly (every six months) to rule out the presence of visual disturbances, even if you do not notice any change in your vision.
