slide2. Learning Outcomes After completing this session, students will be able to:
Demonstrate Knowledge of key pediatric dosing principles and common calculation methods.

Ensure Safe Dosing Practices<br>
slide3. Contents CHILD DOSE CALCULATION 01 DOSE CALCULATION RELATED TO AGE 02 PRACTICAL APPLICATIONS 03<br>
slide4. CHILD DOSE CALCULATION Young’s Rule
Dilling’s Rule
Fried’s Rule
Clarke’s Rule<br>
slide5. DOSE CALCULATION RELATED TO AGE Young’s Rule: (for children 1–12 years)
Child’s dose= Age in years × Adult Dose
Age + 12 Example: If the adult dose is 500 mg, and the child is 6 years old,
Child’s dose== Age in years × Adult Dose
Age + 12
=_____6_____×500 = 166.67 mg
6+12<br>
slide6. Dilling’s Rule:(for children 1–20 years)
Child’s dose = Age in years​ × Adult Dose
20 Example, A doctor prescribes Ibuprofen for pain relief.
Adult dose = 600 mg
Child’s age = 8 years
Child’s Dose = 8 × 600
20
= 0.4× 600
= 240mg The child should receive 240 mg of Ibuprofen<br>
slide7. Fried’s Rule Child’s Dose= Age in Months × Adult Dose
150
Example,A doctor prescribes Paracetamol for an infant.
Adult dose = 500 mg
Child’s age = 12 months
Child’s Dose= 12 × 500 = 0.08× 500=40mg
150
The infant should receive 40 mg of Paracetamol<br>
slide8. Child’s Dose= Childs Weight(kg)×2.2 × Adult dose
150
Example, An adult dose of a medication is 600 mg. What is the correct dose for a child weighing 18 kg?
Child’s Dose= 18×2.2 × 600 = 39.6 × 600 = 158.4mg
150 150 The child should receive approximately 158.4mg Clarke’s Rule<br>
slide9. PRACTICAL APPLICATIONS 1.Pediatric Drug Prescriptions

3.Overdose & Poisoning Management
4.Chemotherapy & Specialized Treatments
