I had my insulins always in the fridge before I changed to keeping them out when in use. I thought that the action of the insulin was better keeping it out the fridge. Then I discovered that towards the end of the month when I always take new insulins the insulin I kept out was not performing properly, giving me many sudden highs. When I changed to the new bottles there was a notable difference in the readings coming down. This is a bit of a problem now. I can change a little earlier, maybe when I notice the higher readings, it is time to change the insulins.
Do any of you have the same experience? Or is this a JB special?

I have noticed the same thing. The insulin when kept out of the fridge loses its effectiveness after so long. It just depends on the insulin. Lantus can stay out of the fridge for 28 days after being opened according to the manufactures recommendations. I however don't believe it.

I take Lantus and Humalog too, in the pens. I store them in the frig until I need to use one, then I keep it out. But I go through a pen in a few days so this is not a problem for me. Pharmacy sent me some vials and said keep it in the frig, but when opened it can stay out for 28 days.

I use Humalog in my pump. The box says to keep in refrig until opened. I keep my opened vitals in the refrig during the summer when I worry about the heat getting to it. But during the winter I keep in with my other pump supplies. So far I haven't had any problems with that. I keep my insulin in a cool container when I go places during the summer months.

Hi I keep both my insulins OUT of the fridge , lantus and Humulin and I've NEVER had a problem! Toward the end of the month I change them out! It works great!
