Dosing calculations can be complex and require accurate measurements of weight and, sometimes, BSA. Common methods include:
- Weight-Based Dosing: Often expressed in mg/kg. For example, if the dose is 10 mg/kg and the child weighs 20 kg, the dose would be 200 mg. - BSA-Based Dosing: Calculated using formulas like the Mosteller formula: BSA (m²) = √[(height in cm × weight in kg) / 3600]. - Age-Based Dosing: Less common but used for certain medications.
