Anaphylaxis is a life threatening condition that generally requires quick and decisive management. Studies have shown that carers and first aiders are often delaying definitive treatment by giving the patient an antihistamine rather than using the EPIPEN. In some cases this could seem to be the better option but may actually delay the treatment that is actually needed.
If a patient presents with signs of severe anaphylaxis including a rash, shortness of breath, swollen eyes, difficulty swallowing and has a known history of anaphylaxis, then the EPIPEN is a better option.
