felbamate 400 MG Oral Tablet [Felbatol]
What it is used for
Felbatol ® is not indicated as a first line antiepileptic treatment (see Warnings ). Felbatol ® is recommended for use only in those patients who respond inadequately to alternative treatments and whose epilepsy is so severe that a substantial risk of aplastic anemia and/or liver failure is deemed acceptable in light of the benefits conferred by its use. If these criteria are met and the patient has been fully advised of the risk and has provided written acknowledgment, Felbatol ® can be considered for either monotherapy or adjunctive therapy in the treatment of partial seizures, with and without generalization, in adults with epilepsy and as adjunctive therapy in the treatment of partial and generalized seizures associated with Lennox-Gastaut syndrome in children.
