    Felbamate (Felbatol)

    • Treats partial seizures alone and some partial and generalized seizures in Lennox-Gastaut Syndrome; is used rarely and only when no other medications have been effective.
    • Side effects include decreased appetite, weight loss, inability to sleep, headache, and depression. Although rare, the drug may cause bone marrow or liver failure.
