Fried's formula for determining the medicine dosage for children aged 1 - 2 years is:
\(\text{Dosage}=\dfrac{\text{Age of infant (months)}\ \times \ \text{adult dose}}{150}\)
The spreadsheet below is used as a calculator for determining an infant's medicine dosage according to Fried's formula.
Amber, a 12 month old child, is being discharged from hospital with two medications. Medicine A has an adult dosage of 325 milligrams and she is to take 26 milligrams. She must also take 9.6 milligrams of Medicine B but the equivalent adult dosage has been left off the spreadsheet.
