if you aska diabetic they would laugh at the idea of slin going bad in a month. even at the idea of it having to be refridgerated. my aunts diabetic and she keeps a boatload in her cabinet.
Um, bullshit.
I go through more than a vial a month, so thats irrelevant, but insulin can be EXTREMELY temperature sensitive depending on what type you have. I've had major problems with a bottle of Humalog recently and years ago a bottle of Regular that I thought didn't need to be refrigerated, so I hauled it around in my {air conditioned} car on a warm summer day. That pretty much rendered it useless. Storing it in a cabinet is flat out stupid in my opinion.
I've copied the protocols for insulin handling from the diabetic childrens camps I have worked with. My insulin is kept on ice or in a refrigerator
at all times. That shit is too expensive and my life is too important to mess around with temperature thinking its "safe".
