💡 About Pediatric Dosage Calculation
Pediatric drug dosing requires careful calculation based on weight, body surface area, or age to ensure safety and efficacy in children.
Weight-Based Formula: Dose = Weight (kg) × Dosage (mg/kg)
BSA Formula: Dose = BSA (m²) × Dosage (mg/m²)
BSA Calculation: √[Weight (kg) × Height (cm) / 3600]
Note: Always use the most recent pediatric dosing guidelines and consider individual patient factors.
