Felbatol is used for partial seizures—that is, seizures that begin in a limited area of the brain. Sometimes these seizures spread throughout the brain (generalize). It is approved to be used either by itself or as adjunctive therapy—that is, to be added to other seizure medicine.

Felbatol is also used in combination with other seizure medicine to treat children with Lennox Gastaut syndrome.

IMPORTANT
The use of Felbatol is recommended only for people whose seizures have not responded to other medications and are so severe that a substantial risk of failure of the bone marrow (aplastic anemia) or liver failure is considered acceptable in light of its potential benefits. If you are in this situation, the risks will be fully explained to you and you will be asked to sign a written consent form. Before deciding to use Felbatol, read about the serious side effects here and ask your doctor or pharmacist for more extensive written information.
