Out of 49 epileptic children treated with diphenylhydantoin and phenobarbital there were 36 cases with poor or partial control of seizures, among whom 20 cases had serum diphenylhydantoin levels below 5 γ/ml and 8 cases had serum phenobarbital levels below 10 γ/ml. Thus estimation of serum levels of each of drugs has proved to be a valuable guide in management of childhood epilepsy.
