Patient Education

Felbamate


Felbamate is used to treat certain seizures in adults and children with epilepsy whose seizures have not improved with other treatments. It is used alone or in combination with other medications to treat partial seizures in adults. It is used in combination with other medications to treat partial and generalized seizures in children with Lennox-Gastaut syndrome (a disorder that causes seizures and developmental delays). Felbamate is in a class of medications called anticonvulsants. It works by decreasing abnormal activity in the brain.
