Abstract
Half-unit insulin pens (HUPs) offer finer gradation of insulin dosing than their integer-unit counterparts, tackling the inaccuracies of dose rounding that make it difficult for insulin-sensitive populations to achieve tight glycemic control. This article analyzes the first prefilled HUP, the Humalog Junior KwikPen, in the context of other, similar devices and the developing landscape of smart insulin pens. The Junior KwikPen's suitability for pediatric patients is assessed in reference to a recent study surveying its accuracy and usability under varying conditions intended to simulate real-world use.
