Febrile seizure (FS) is the most common form of childhood seizure disorders. FS is perhaps one of the most frequent causes of admittance to pediatric emergency wards worldwide. We aimed to identify a new, safe, and effective therapy for preventing FS recurrence.A total of 115 children with a history of two or more episodes of FS were randomly assigned to levetiracetam (LEV) and control (LEV/control ratio=2:1) groups. At the onset of fever, LEV group was orally administered with a dose of 15-30mg/kg per day twice daily for 1week. Thereafter, the dosage was gradually reduced until totally discontinued in the second week. The primary efficacy variable was seizure frequency associated with febrile events and FS recurrence rate (RR) during 48-week follow-up. The second outcome was the cost effectiveness of the two groups.The intention-to-treat analysis showed that 78 children in LEV group experienced 148 febrile episodes. Among these 78 children, 11 experienced 15 FS recurrences. In control group, 37 children experienced 64 febrile episodes; among these 37 children, 19 experienced 32 FS recurrences. A significant difference was observed between two groups in FS RR and FS recurrence/fever episode. The cost of LEV group for the prevention of FS recurrence is lower than control group. During 48-week follow-up period, one patient in LEV group exhibited severe drowsiness. No other side effects were observed in the same patient and in other children.Intermittent oral LEV can effectively prevent FS recurrence and reduce wastage of medical resources.
