Allergic ADRs are not dose-related and require prior exposure. : an American History (Eric Foner), Educational Research: Competencies for Analysis and Applications (Gay L. R.; Mills Geoffrey E.; Airasian Peter W.), Principles of Environmental Science (William P. Cunningham; Mary Ann Cunningham), The Methodology of the Social Sciences (Max Weber), Surgical Case 02 Stan Checketts GRQ Edited. "There are times when people have had an anaphylaxis and they have not administered adrenaline and they've been lucky that it has self-limited," Ms Said said. Adrenaline auto-injector devices are prescribed by a doctor for those at risk of a severe reaction based on an individual need assessment carried out by the doctor. Understanding anaphylaxis, Most rapid onset reactions will only cause mild to moderate symptoms, However a more severe reaction (anaphylaxis) can occur and cannot easily be predicted, Whilst such a severe reaction is potentially life-threatening deaths are rare, In the case of sting or bites, localised swelling at sting site, Change in voice (Hoarse or croaky sounds), Wheeze (whistling noise due to a narrowed airway), In babies and young children this may look like the sudden onset of paleness and floppiness, Having had a previous severe allergic reaction or reactions, Having a history of asthma, especially if this is not well controlled see further advice below, The greater the dose/amount of allergen exposed to the greater the risk of a severe reaction, Higher risk a food being ingested, a sting, or a medicine being given by injection, Lower risk food particles being inhaled or touching the skin, a medicine taken by mouth, In some people exercise just before or after eating certain foods, (More rarely in some people exercise alone can cause a severe reaction which is called exercise induced anaphylaxis), Sometimes some people on certain regular medications can be at higher risk your doctor should advise on this, Being unwell with an infection/high temperature, Give adrenaline WITHOUT DELAY- if an adrenaline auto-injector is available, Call an ambulance (999) and tell the operator it is anaphylaxis, Position is important -lie the person flat with legs raised (or sit them up if having breathing problems), Avoid standing or moving the person having the allergic reaction, Stay with the person until medical help arrives.

Certain substances can trigger this severe rapid onset allergic reaction. A second I.V. Allergy / immunology specialists play a uniquely important role to confirm the etiology of anaphylaxis, prepare the patient for self administration of epinephrine, educate the patient and/or family about allergen avoidance, and rule out any underlying condition, such as mastocytosis, which can predispose a patient to develop anaphylaxis. Discuss the differences between mild, moderate, and severe anaphylactic reactions. Discuss the importance of follow-up assessments post-reaction.
