Which formula should a pharmacy technician use to determine the correct pediatric dose for a toddler?

In determining the correct pediatric dose for a toddler, Clark's rule is particularly relevant because it provides a straightforward method for calculating medication dosage based on the child's weight relative to the average adult weight. The formula uses the weight of the child in pounds to help calculate the appropriate dosage proportionate to adult dosing. This method is well-suited for toddlers, who may vary significantly from average adult reference levels, ensuring that the medication is dosed safely and effectively.

While Fried's rule is also a method used for pediatric dosing, it is specifically designed for children under the age of 2 and may not be as applicable for toddlers. The body surface area method, while accurate, typically requires more complex calculations and is often used in more specific contexts or in oncology treatments. Young's rule, another method for calculating pediatric doses, can be somewhat less precise than Clark's rule for toddlers. Therefore, Clark's rule stands out as an effective and widely used formula for this age group, ensuring that the toddler receives an appropriate and safe dose based on their weight.
