How to Use

Starting dose should be 0.01 mg to 0.03 mg per kilogram of body weight daily, divided into 2–3 doses, with a maximum of 0.05 mg per kilogram. Maintenance doses are normally 0.1 mg to 0.2 mg per kilogram of body weight, adjusted gradually by the doctor until the child’s seizures are under control.
