Paediatric drug dosing is weight-based (mg/kg). Children's absorption, distribution, and metabolism differ significantly from adults. Always confirm with a prescriber.
ସୂତ୍ର
Clark's rule: Child dose = (Weight in lbs / 150) × Adult dose; Young's rule: (Age / Age+12) × Adult dose; mg/kg dosing preferred (dose = Weight kg × mg/kg)

Why are pediatric doses different?
Children metabolize drugs differently (slower kidney/liver function in infants). Surface area scaling matters. Proportionally higher drug effect possible (toxicity risk). Always use weight-based dosing.
Should I use Clark's rule or weight-based?
Weight-based (mg/kg) standard now. Clark's rule (weight-based) or Young's rule (age-based) historical. Age-based less accurate. Check pediatric references or pharmacist.
What if dose seems too small?
Verify drug, weight, and reference source. Underdosing common mistake. Double-check with pharmacist before giving. Overdosing = toxicity; underdosing = treatment failure.
