I was helping dispose of some old medication today. We tossed some ampules of epi that expired in 2005 (its a long story.) I was wondering what happens to epi when it expires?
I tried Googling this, but got no answer. If I was to inject someone with 0.3mg of 1:1000 IM epi that was five years expired, what would happen? Would it work, but at a reduced strength or something else? There was no precipitate in the ampule or discoloration.
And just to be clear, I'm only asking because the RN on staff didn't know and I just want my curiosity satisfied.
