This subject has been brought up on a number of other threads, but I want to encourage everyone to take steps to keep yourself or your young ones alive in the event of an emergency. Don’t rely on luck, or chance, or on always having access to a doctor, pharmacy, or hospital in an emergency. Instead, rely on yourself and your foresight to be prepared. Make it a point to build up at least a small supply of emergency insulin.
I have done personal experiments with expired insulin. And I have done personal experiments with un-refrigerated insulin. What I am working on now is both expired AND un-refrigerated. Just so there is no issue with what I am saying - I am not suggesting anyone ever use expired or un-refrigerated insulin, unless there is an emergency.
As far as a life-preserving stash, keep in mind that in an emergency, things like CGM and pumps are luxury items. The basic stuff you need to keep you alive is insulin and syringes.
Syringes are available with no prescription (check out Amazon). If you don’t have a box or two, get some!
I’ll report back on expired AND un-refrigerated insulin. And I’ll reiterate - don’t use it unless it’s an emergency.
