for what reason can't you just use an epipen, (epinephrine) after having an allergic reaction/anaphylaxis, and then not go to the emergency room?

It may help for ...: Only a little while. The Epinephrine in the Epipen counteracts the allergic reaction. But as your body metabolizes the epinephrine, its effects wear off. If the allergic reaction is severe enough, the symptoms may come on again. Severe allergic reactions may involve difficulty breathing and cardiovascular problems, not just swelling and rash, so a prompt subsequent trip to the er is prudent.
