title: Drug prescribing in infants and children.
abstract: Many ambulatory pediatric encounters result in drug therapy. Drug dose determination, based on a child's weight, can often be simplified by modifying the order of mathematical calculation. Specifically, multiplying by body weight as the last calculation, rather than as the initial calculation, often yields values easily manipulated mentally. With this mathematical manipulation, the identical calculation is often performed repetitively which, with time, may facilitate the calculation.
