Formula

Daily range = mg/kg/day × weight
Per dose = daily amount ÷ number of doses per day

How it is used

• Look up the recommended mg/kg/day range in a pediatric drug reference; the numbers differ for each drug and indication.
• Compare the ordered dose with the range. Doses below the range may be ineffective; doses above it are unsafe.
• Some drugs also have an absolute maximum per dose that applies to larger children.
