Pediatric Dose Calculator
Calculate safe medication doses for children based on weight and prescription
Calculate Pediatric Dose
Child Information
Amount prescribed by healthcare provider
How the dose is prescribed
How often the medication is given
Drug Concentration
Example: Paracetamol syrup "120 mg per 5 ml" → Drug Amount: 120 mg, Per Volume: 5 ml
Dosage Results
Example Calculation
Paracetamol for Fever 🤒
Child: 4.5 years old, weighs 20 kg
Prescription: 10 mg/kg per day
Frequency: BID (twice daily)
Medicine: Paracetamol syrup 120 mg/5 ml
Step-by-Step Calculation
1. Concentration: 120 mg ÷ 5 ml = 24 mg/ml
2. Total daily dose: 10 mg/kg × 20 kg = 200 mg
3. Volume per dose: 200 mg ÷ (24 mg/ml × 2) = 4.17 ml
Result: Give 4.2 ml twice daily (8.4 ml total per day)

Pediatric Safety Tips
Always use proper measuring tools (not kitchen spoons)
Weigh child regularly - doses change with growth
Keep medication log with times and amounts
Consult pediatrician before any medication
Understanding Pediatric Dosing
Why Special Pediatric Calculations?
Children are not simply small adults. Their bodies process medications differently due to:
- •Rapidly changing body weight and composition
- •Developing organ systems (liver, kidneys)
- •Different drug absorption and metabolism
- •Increased sensitivity to medication effects
Dosage Types Explained
mg/kg/day
Most common - total daily dose based on weight, divided by frequency
mg/kg/dose
Each individual dose based on weight
mg/day or mg/dose
Fixed amounts not based on weight
Critical Safety Considerations
Remember
- • Pediatric dosing errors can be life-threatening
- • Always verify calculations with healthcare providers
- • Use only pediatric-specific medications when available
- • Regular weight checks ensure accurate dosing
- • This tool provides estimates - professional judgment is essential
