Monitoring unbound phenytoin concentrations may be particularly relevant for patients with renal or hepatic disease or hypoalbuminemia.
Pediatric Patients
The recommended starting dose for pediatric patients new to Dilantin treatment is typically 5 mg/kg/day orally‚ divided into two or three equally spaced doses. Dosage adjustments may be made based on individual requirements‚ not exceeding a maximum of 300 mg daily in divided doses. The usual daily maintenance dosage for most pediatric patients ranges from 4 to 8 mg/kg/day‚ administered in equally divided doses.
Recommended Starting Dosage and Maintenance
For pediatric patients new to Dilantin treatment‚ the typical starting dosage is 5 mg/kg/day administered orally in two or three equally divided doses. Dosage adjustments should be made based on individual needs‚ not exceeding a maximum of 300 mg daily in divided doses. The recommended daily maintenance dosage for most pediatric patients usually falls within the range of 4 to 8 mg/kg/day‚ given in equally divided doses as prescribed.
Importance of Individualized Dosage for Maximum Benefit
Individualizing the dosage of Dilantin for pediatric patients is crucial to ensure optimal treatment outcomes. With the recommended starting dose being 5 mg/kg/day and subsequent adjustments based on individual needs‚ it is essential to tailor the dosage to each child’s requirements.
