1. What Rufinamide Eisai is and what it is used for

Rufinamide Eisai contains a medicine called rufinamide. It belongs to a group of medicines called antiepileptics, which are used to treat epilepsy (a condition where someone has seizures or fits).

Rufinamide Eisai is used with other medicines to treat seizures associated with Lennox-Gastaut syndrome in adults, adolescents and children from 1 year of age. Lennox-Gastaut syndrome is the name given to a group of severe epilepsies in which you may experience repeated seizures of various types.

Rufinamide Eisai has been given to you by your doctor to reduce the number of your seizures or fits.

2. What you need to know before you take Rufinamide Eisai

Do not take Rufinamide Eisai:

if you are allergic to rufinamide or
triazole derivatives or any of the other ingredients of Rufinamide Eisai (listed in section 6).

Warnings and precautions

Talk to your doctor or pharmacist if:

you have Congenital Short QT
Syndrome or a family history of such a syndrome (electrical disturbance of the heart), as taking rufinamide could make it worse.
you suffer from liver problems.
There is limited information on the use of rufinamide in this group, so the dose of your medicine may need to be increased more slowly. If your liver disease is severe the doctor may decide Rufinamide Eisai is not recommended for you.
you get a skin rash or fever.
These could be signs of an allergic reaction. See the doctor immediately as very occasionally this may become serious.
you suffer an increase in the
number or severity or duration of your seizures, you should contact the doctor immediately if this happens.
you experience difficulty
walking, abnormal movement, dizziness or sleepiness inform the doctor, if any of these happen.

if you take this medicine and have thoughts of harming or killing yourself at any time, contact your doctor or go to a hospital straight away (see section 4).

Consult the doctor, even if these events occurred at any time in the past.

Children

Rufinamide Eisai should not be given to children younger than 1year of age since there is not enough information on its use in this age group.

Other medicines and Rufinamide Eisai

Tell the doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription. If you are taking the following medicines: Phenobarbital, fosphenytoin, phenytoin or primidone, you may need to be carefully monitored for two weeks at the start of, or after the end of treatment with rufinamide, or after

any marked change in the dose. A change in the dose of the other medicines may be needed as they may become slightly less effective when given with rufinamide.

Antiepileptic medicines and Rufinamide Eisai

If the doctor prescribes or recommends an additional treatment for epilepsy (e.g., valproate) you must tell the doctor you are taking Rufinamide Eisai as the dose may need adjusting.

Adults and children taking valproate at the same time as rufinamide will result in high levels of rufinamide in the blood.

Tell your doctor if you are taking valproate as the dose of Rufinamide Eisai may need to be reduced by your doctor.

Tell the doctor if you are taking hormonal/ oral contraceptives, e.g., “The pill”. Rufinamide Eisai may make the pill

not effective at preventing pregnancy. Therefore, it is recommended that you use an additional safe and effective contraceptive method (such as a barrier method, e.g. condoms) when taking Rufinamide Eisai.

Tell the doctor if you are taking the blood thinner – warfarin. The doctor may need to adjust the dose.

Tell the doctor if you are taking digoxin (a medicine used to treat heart

conditions). The doctor may need to adjust the dose.
