How do you use Fried's rule? I see Young's and Clark's on this site, but not the formula for fried's. Please let me know more about this dosage calculation.

Fried's Rule Formula
by: Jerry

Fried's Rule is available to use to calculate an infant dosage for patients under 24 months when a proper dosage has not been already determined. It most likely would never be asked about on the PTCB exam, and that's why there's no tutorial for it on the website.

I added a picture above to show the formula.

But, it's basically just like Clark's rule, but use months instead of weight.

Months
------- X Adult Dosage
150

Because Liter represents volume and liquid equals to 1000 milliliter.
Reason for 150

A child of 12.5 years old is for many considered an adult for dosage purposes. Twelve and a half years equals 150 months old
why 150 used to divide

150 is used since that is determined to be the weight of an "average" adult and adult doses are based on a 150lb patient
