Inovelon 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).
Inovelon 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.
Inovelon has been given to you by your doctor to reduce the number of your seizures or fits.
Talk to your doctor or pharmacist if:
Consult the doctor, even if these events occurred at any time in the past.
Inovelon should not be given to children younger than 1 year of age since there is not enough information on its use in this age group.
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 Inovelon
If the doctor prescribes or recommends an additional treatment for epilepsy (e.g., valproate) you must tell the doctor you are taking Inovelon 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 Inovelon may need to be reduced by your doctor.
Tell the doctor if you are taking hormonal/oral contraceptives, e.g., “The pill”. Inovelon 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 Inovelon.
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.
See section 3 – ‘How to use Inovelon’ for advice on taking Inovelon with food and drink.
If you are pregnant, or think you might be pregnant, or are planning to get pregnant, ask the doctor or pharmacist for advice before taking Inovelon. You must only take Inovelon during your pregnancy if the doctor tells you to.
You are advised not to breast-feed while taking Inovelon, as it is not known if rufinamide will be present in breast milk.
If you are a woman of childbearing age, you must use contraceptive measures while taking Inovelon.
Ask the doctor or pharmacist for advice before taking any medicine at the same time as Inovelon.
Inovelon may make you feel dizzy, drowsy and affect your vision, particularly at the beginning of treatment or after a dose increase. If this happens to you, do not drive or operate machinery.
Inovelon contains 175 mg sorbitol (E420) in each mL. Sorbitol is a source of fructose. If your doctor has told you that you (or your child) have an intolerance to some sugars or if you have been diagnosed with hereditary fructose intolerance (HFI), a rare genetic disorder in which a person cannot break down fructose, talk to your doctor before you (or your child) take or receive this medicine.
Sorbitol may cause gastrointestinal discomfort and mild laxative effect.
Taking Inovelon with other anti-epileptic medicine which contains sorbitol, may affect how much they work. Tell your doctor or pharmacist if you are taking any other anti-epileptic medicine(s) with sorbitol.
Inovelon contains less than 0.01 mg benzoic acid (E210) in each mL. Benzoic acid may increase jaundice (yellowing of the skin and eyes) in newborn babies up to 4 weeks old.
This medicine contains less than 1 mmol sodium (23 mg) per daily dose, that is to say essentially ‘sodium-free’.
These ingredients may cause allergic reactions (possibly delayed).
Always take this medicine exactly as your doctor has told you. Check with the doctor or pharmacist if you are not sure.
It may take a while to find the best dose of Inovelon for you. The dose will be calculated for you by the doctor and will depend on your age, weight and whether you are taking Inovelon with another medicine called valproate.

The recommended starting dose is 10 mg (0.25 ml) for each kilogram of body weight, each day. Taken in two equal doses, half in the morning and the other half in the evening.
