Q1. An infant, 10 months old and weighing 18 pounds, needs
Streptomycin Sulfate, which is usually administered to adults as
1 g (1000 mg), as a daily IM injection. What is the appropriate
dosage for the infant?


What you'll need:

Fried's rule formula: (Child's dose=(Age in months)/150×Adult dose)

This formula is used for children (infants) who are younger than 1 year of age. The rule is based on both the child's age as well as the average adult dosage for a 150-lb. adult.

Q2. A child, 12 months old, needs erythromycin, and the normal adult dose is 250 mg QID. What is the appropriate dosage for the child?
