Question:

The recommended adult dose for penicillin is 200 mg PO Q6H.

What would the dose be for a 2yr-old infant? (Use Fried’s rule to complete the problem.)

Solution:

Formula:

$$Child\ dose = \left(\frac{Age\ of\ child\ in\ month}{150\ lbs}\right) Average\ adult\ dose.$$

The dose for a 2yr-old infant is

$$Child\ dose = \frac{24}{150\ lbs} 200\ mg = 32\ mg.$$
