Before deciding to use Felbatol, read about the serious side effects here and ask your doctor or pharmacist for more extensive written information.

Felbatol is used to treat children with partial seizures either by itself or in combination with other seizure medicines. It is also used in combination with other seizure medicines for seizures in children with Lennox-Gastaut syndrome.

Doctors figure out how much medicine to give to young children based mostly on their weight. To keep side effects at a minimum, the doctor probably will prescribe a low dose to start with and increase it slowly. For Lennox-Gastaut syndrome, Felbatol should be started at 15 milligrams (mg) per kilogram (kg, about 2.2 pounds) of body weight per day. This amount is divided into three or four doses. The dosage of Felbatol is increased by 15 mg per kg per day at weekly intervals until seizures are brought under control or unacceptable side effects occur. A typical ongoing dose is 45 mg per kg per day.

If the liquid suspension is used, it is very important to thoroughly shake the bottle immediately before measuring. A child who gets a dose from a bottle that has not just been well shaken may get too much or too little medication.
