Hi tealBumblebee

I'm sorry you had to go through that. I don't know the answer to this and others wouldn't either. Is there a way you could call a nurse hotline from either your insurance company or if that is not an option could you call your local ER and ask a nurse this question? It would be safer to know this information from them.

I wish you the best.

I had a similar question with an epi-pen that had been in sub-par conditions and my doctor told me not to tamper with it, to carry it with me, it probably still worked, but the best option was to refill the prescription because JIC can mean saving my life.

I've had anaphalactic shock three times, from three different things. If necessary, I'd dumpster dive for aluminum cans in order to get enough money to make sure I had working epi-pens. If you have any doubts at all -- any -- make sure you have a good epi.

I'm so sorry you had such a bad reaction. It's scary and far worse than what most people think of as an allergic reaction. I also carry Benedryl with me all the time, too.
