Humalog Junior KwikPen is the only rapid-acting insulin pen that offers the combined benefits of a prefilled disposable pen and half-unit dosing.

Humalog Junior KwikPen is different from Humalog KwikPen because it can dose in half-unit increments. Plus, because it's a KwikPen, it shouldn’t be refrigerated after the first use,* and you can take it just about anywhere. You can carry it in your purse, your child’s backpack, or a pocket because it’s the size of a marker. Remember to always carry an extra pen.
