- Patients for whom the risk-to-benefit ratio supports use because there is class I evidence for benefit:
- Lennox-Gastaut patients over the age of 4 years who are unresponsive to primary antiepileptic drugs (AEDs)
- Those patients older than 18 years of age who have intractable partial seizures and in whom the use of standard AEDs at therapeutic levels has failed (Data indicate a better risk to benefit ratio for felbamate used as monotherapy.)
- Patients who have been on felbamate more than 18 months
- Patients for whom the current risk-to-benefit assessment does not support the use of felbamate:
- Adults or children with new-onset epilepsy
- Patients who have experienced significant prior hematologically adverse events
- Patients in whom follow-up and compliance do not allow careful monitoring
- Patients unable to discuss risks to benefits (i.e., with mental retardation, developmental disability) and for whom no parent or legal guardian is available to provide consent
- Patients in whom the risk-to-benefit ratio is unclear and based on case reports and expert opinion (class III) only, but under certain circumstances depending on the nature and severity of the patient's seizure disorder, felbamate use may be appropriate:
- Children with intractable partial epilepsy
- Other generalized epilepsies unresponsive to primary agents
- Patients who experience unacceptable sedative or cognitive side effects with traditional AEDs
- Patients with Lennox-Gastaut syndrome younger than 4 years of age who are unresponsive to other AEDs
