I noticed that, on several recent PM threads I was invited to, some people mentioned the improved longevity of glucagon when refrigerated.
Lilly Glucagon kits
The documentation provided by Lilly for the latest version of Glucagon does not indicate that. In fact, it specifically requests that it not be refrigerated. Lilly provides a good documentation page for Glucagon, which mentions storage in the FAQs:
"How should Glucagon be stored? Before dissolving Glucagon with diluting solution: Store the kit at room temperature (68° to 77°F). Do not refrigerate or freeze. Keep away from direct sunlight."
Of course, their controlled temperature range (68° to 77°F) is almost impossible to keep when outdoors…
Novo Nordisk Glucagen kits – US documentation
The GlucaGen® package may be stored up to 24 months at controlled room temperature 20° to 25° C (68° to 77° F) prior to reconstitution. Do not freeze. Keep in the original package to protect from light. GlucaGen® should not be used after the expiry date on the vials
