Epipens can be dangerous, even when administered correctly.

People need to know that even though the symptoms should improve when they take the epipen they still need to go to hospital because other treatment and often additional adrenalin may be required- epipen is kinda a first aid move.

Diagnosis of who needs an epipen can be complex - its not always clear to people if what they had was anaphylaxis or not (severe episodes are generally fairly identifiable, but milder episodes can be tricky - a combo of rash and vomiting might need someone to have access to an epipen even though thats not what most people think of when they think anaphylaxis).
