What is felbamate?

Felbamate is an anti-epileptic medication, also called an anticonvulsant.

Felbamate is used alone or in combination with other medications to treat seizures in adults with epilepsy. Felbamate is also used to treat children with Lennox-Gastaut syndrome, a severe form of childhood epilepsy that also causes developmental and behavior problems.

Felbamate is usually given after other seizure medications have been tried without successful treatment of symptoms.

Felbamate may also be used for purposes not listed in this medication guide.

What should I discuss with my healthcare provider before taking felbamate?

Felbamate can cause serious side effects and is usually given only to people with severe epilepsy when the need for seizure control outweighs the risk of side effects. You may be asked to sign a consent form after you and your doctor have discussed the risks and benefits of taking felbamate.
