Insulin Lantus with frost on the catridge

[TTBLR]

Hi!

I found that I have been keeping Lantus in the temperature near 0 degrees (C). The catridges had a tiny layer of frost(not ice), which can be easily cleared. Lantus is for sure still working, do not know if the way it should.

Anyone having an issue like that?

Thank you

That is actually too cold for storing Lantus:

Unopened LANTUS vials, cartridge systems and SoloStar device should be stored in a refrigerator, 36 F- 46 F (2 C- 8 C). If the vial/pen freezes it can compromise the effectiveness of the insulin
