Today I realized that I left my purse in my car for several days, in temperatures well below freezing. In my purse was an epipen. It was in the cold, and quite possibly frozen, for at least 72 hours, possibly longer. I know that the pens aren't especially shelf-stable even under the best of circumstances--is it still good?

Googling reports that the company suggests that you replace the pen after something like this, but doesn't say much about if the efficacy of the pen is actually affected. I'm torn--I have no health insurance, and paying $150 to see a doctor, get a prescription, and then get it filled would be a major financial blow right now. On the other hand, I'm well aware that holidays have, for me, a much higher than usual chance of encountering allergens.
I have severe food allergies and carry two pens with me most of the time. I have the second one, which, luckily, I'd left at home (because apparently fortune favors the stupid), but have previously had reactions where a second pen was needed to bring the reaction under control, and the idea of not having a backup is pretty scary. If the frozen one will work or mostly work, I'll hold on to it, otherwise I'll try to get a new one before the yearly week of gluttony begins.
Any information you have about the effectiveness of thawed from frozen adrenaline would be greatly appreciated.
