Determining the correct dose of medication for a pediatric patient requires careful consideration of the child's specific characteristics and needs. Weight-based dosing, expressed in milligrams per kilogram (mg/kg), is the most reliable method because it ensures that the medication is tailored to the individual child's body size and metabolic capabilities.

This method allows for a more accurate dosage that accounts for the various physiological differences between children and adults, including variations in absorption, distribution, metabolism, and excretion of drugs. Since children can vary widely in weight, relying solely on age or standard adult doses (which are not appropriate for the smaller body mass of pediatric patients) could lead to underdosing or overdosing, potentially resulting in ineffective treatment or harmful side effects.

Using body surface area (BSA) is another valid method for certain medications; however, it is often more complex to calculate and is primarily utilized for specific cases, such as chemotherapy. It is not as universally applicable as weight-based dosage, especially for the majority of pediatric medications. Therefore, calculating the medication dose based on weight in mg/kg is the preferred and most commonly practiced method for dosing in pediatric patients.
