Moments later I remembered what the diabetes educator had told us in training: never throw away a box of unused glucagon. Use it for practice, or donate it to the hospital and they will use it to teach someone recently diagnosed. In neither case would it be injected for real, but the act of drawing out the water, injecting it into the vial, mixing, and redrawing the solution into a syringe is good practice, and might help avoid the foamy mess I created the first time I ever had to use glucagon in an emergency situation.
Which led to to remember the numerous and horribly frightening times in which we've needed to give Dylan glucagon. Times when it made the difference between life and death; bringing up a dangerously low blood sugar in a matter of minutes. Part of me feels gratitude towards this little box and its capabilities. Another part of me is relieved that glucagon does, in fact, expire in our house now, because it means we didn't need to use it. I can only hope there are many more unused expires boxes in the future.
What do you do with expired glucagon?
