Formula Used
Dose (mg) = Weight (kg) × Dosage (mg/kg/day)
Where:
- Weight = Child's weight in kilograms
- Dosage = Recommended dosage based on indication (14 mg/kg/day for most indications, 7 mg/kg/day for otitis media)
- Volume (mL) = Dose (mg) ÷ Concentration (mg/mL)
Example Calculation
Real-World Scenario:
A 3-year-old child weighing 15 kg (33 lbs) needs treatment for acute otitis media with cefdinir 125 mg/5 mL suspension.
Given:
- Weight = 15 kg
- Indication = Acute Otitis Media
- Dosage Form = 125 mg/5 mL Oral Suspension
Calculation:
For otitis media, the recommended dosage is 7 mg/kg/day once daily or 14 mg/kg/day divided twice daily.
Once daily: 15 kg × 7 mg/kg/day = 105 mg/day
Twice daily: 15 kg × 14 mg/kg/day = 210 mg/day ÷ 2 = 105 mg per dose
Volume to administer: 105 mg ÷ (125 mg/5 mL) = 4.2 mL
Result: Administer 4.2 mL once daily or 2.1 mL twice daily
