Most insulins that you are currently using, whether pens or vials, can be kept at room temperature for up to 28 days with no ill effects or deterioration. The Novolog insert states under "Novolog in Use-Vials: Keep in the refrigerator or at room temperature below 86 degrees F for up to 28 days. Under Novolog in Use-Penfill Cartridges or Novolog Flexpen, Keep at room temperature below 86 degrees F for up to 28 days ." In fact, room-temperature insulin is easier on your body when you inject it. I know this is true for Novolog and Humalog. Other kinds of insulin may have different parameters of use. Any unopened vials or pens of Novolog or Humalog should be stored in the refrigerator. Somewhere in the inserts with the insulin, you will find the guidelines spelled out (but who bothers to ever read that stuff!…I finally did when I had to fight with my insurer who supplied me with 2 vials of insulin for a 90-day period…Novolog's insert states "Throw away an opened vial after 28 days of use, even if there is insulin left in the vial"…so I won my argument with them that I needed 3 vials for 90 days.)

It's definitely worth it to read the fine print in the prescription inserts, because there are different guidelines for different types of insulin, and also for pens. Typically room temperature means 56-86 degrees Fahrenheit. ~Lynn @Glucerna

According to the BD website: "Bottles of insulin, either open or unopened, generally last for one month when stored at room temperature (59 to 86°F). A bottle is considered open if its seal has been punctured. If you remove the cap but don't puncture the seal, the bottle is still considered unopened." The article goes on to say: "If stored in a refrigerator, unopened bottles are good until the expiration date printed on the bottle. Opened bottles that are stored in a refrigerator should be used within one month of being opened. Many people store their unopened bottles in the refrigerator and keep open bottles at room temperature because they find it uncomfortable to inject cold insulin.

I pray that answers your question adequately

I have always been told this is true. Insulin in the pens can stay out longer but needs to eventually be put back in the fridge. I can carry my pens around for a day but put them in the fridge at night.
