Because of concerns that Felbatol increases the risk of a few rare but serious and potentially life-threatening disorders, Felbatol (felbamate) is used very rarely. For people with severe epilepsy that is not well controlled by other seizure medicines, however, it may be worth considering, either alone or as an add-on. Before deciding to use Felbatol, read about the serious side effects here and ask your doctor or pharmacist for more extensive written information.

Doctors have studied people with partial seizures to find out how well Felbatol works. Studies have shown that Felbatol works well alone or when added to other seizure medicines. Felbatol is not a perfect add-on seizure medicine for everyone, however. Sometimes people must try a series of combinations before finding what is best for them. Some other medicines affect how Felbatol is eliminated from the body, and Felbatol may affect the levels of other seizure medicines, so the dosages may need to be changed with different combinations.

Studies have shown that Felbatol is also effective when added to other seizure medicine for partial and generalized seizures in children with Lennox-Gastaut syndrome.
