Before deciding to use Felbatol, read Serious Side Effects here and ask your doctor or pharmacist for more extensive written information.

Felbatol (felbamate) is approved by the FDA to treat patients 14 years and older for partial epilepsy, both as adjunctive (add-on) therapy and for use alone (monotherapy). It also is approved for add-on therapy for partial and generalized epilepsy associated with Lennox-Gastaut syndrome in patients 2 years and older.

Felbatol used as add-on therapy for Lennox-Gastaut syndrome should be added at 15 milligrams (mg) per kilogram (kg, about 2.2 pounds) of body weight per day. This amount is divided into three or four doses. The dosage of Felbatol is increased by 15 mg per kg per day at weekly intervals until seizures are brought under control or unacceptable side effects occur. A typical maintenance dose for long-term use is 45 mg per kg per day.

If the liquid suspension is used, it is very important to thoroughly shake the bottle immediately before measuring. A child who gets a dose from a bottle that has not just been well shaken may get too much or too little medication.
