Novolog (insulin aspart) is a brand of fast-acting insulin used by many people with diabetes to control their after-meal blood sugar levels. It usually comes in autoinjector pens called FlexPens or vials to be used with insulin syringes or pumps.

Like all insulins, Novolog must be handled with care, especially given its sensitivity to temperature.

Ensuring your Novolog FlexPens remain effective involves keeping them at appropriate temperatures, which can be quite a challenge for those leading active lives or who travel frequently.

Whether it's commuting to work, enjoying a vacation, or simply being out for the day, managing Novolog requires conscious planning and specialized carrying cases offering a practical solution for safely transporting your insulin no matter where you are.

Why Use a Special Case to Carry Your Novolog Pens?

Carrying Novolog FlexPens without proper protection is risky. This fragile medication must be shielded from extreme temperatures and physical damage. A specialized, medical-grade carrying case:

  • provides insulation to help maintain the correct temperature, even in warm climates or during summer months.
  • protects your Novolog FlexPens and vials from breakage and physical damage caused by drops or impacts that might occur during your daily activities.

Novolog FlexPen Carrying Cases

Remember that your Novolog FlexPens must be stored in the refrigerator between 36°F to 46°F (2°C - 8°C) until first use. Once opened, they can be kept at room temperature for up to 28 days, but must always be protected from heat, always staying below 86°F (30°C).

So, the choice of your Novolog pen case depends on whether you're transporting opened Novolog insulin at room temperature or unopened insulin that requires refrigeration.

Here are some top options from 4AllFamily designed for daily use to protect your in-use, opened Novolog FlexPens or vials from heat, ensuring they're carried at the optimal room temperature, even on the hottest summer days:
