Example
The doctor has ordered an antibiotic whose average adult dose is 250 mg per day. What would the dosage for this medication be on a child who is 100 cm in length and weighs 25 kg? See the example below.
In this example, 115 mg of medication would be given.
Formula
First, the body surface area (BSA) must be determined:
kg0.425 x cm0.725 x 0.007184 = BSA
The above formula is just one method for determining BSA. Results with other formulas will vary.
Next, the following formula* is used:
| BSA | x adult dose = approx. child dose |
| 1.73 |
