Using Humalog® Premixed Insulin KwikPen®
Humalog KwikPen is a small, lightweight pen that’s prefilled with mealtime insulin. Plus, since it shouldn't be refrigerated after the first use, you can take it just about anywhere. You can carry it in your purse, backpack, or pocket because it’s the size of a marker.
Once you start using Humalog KwikPen, it should be stored at room temperature, below 86°F (30°C), and must be used within 10 days or be discarded, even if it still contains Humalog.
