i think so DOSAGE IN PAEDIATRICS:
Loading dose in an emergency: 15-20mg/kg (max 1.5gm) IV over 1 hour. Initial maintenance, oral or IV: 2mg/kg 12 hourly (preterm); 3mg/kg 12 hourly (1st week of life), 8 hourly (2wk-4yr), 12 hourly (5-12 yr); 2mg/kg (usual max 100mg) 8 hourly (12 yrs) remember also this -Drugs whose efficacy is impaired by phenytoin include: corticosteroids, warfarin, frusemide, oral contraceptives, rifampin, and theophylline
