Anaphylaxis is the most severe type of allergic reaction.
The immune system responds by making an antibody to attack the allergen and this starts off a range of immune system reactions.Īllergies can be mild, moderate or severe. The substance or trigger is called an allergen. Anaphylaxis is a severe allergic reactionĪllergy occurs when the immune system overreacts to a substance or ‘trigger’ in the person’s environment that is typically harmless. If you are thought to be at risk of anaphylaxis or you experience anaphylaxis for the first time, your doctor will refer you to a clinical immunology or allergy specialist, who will formally diagnose you and discuss management particular to your needs and circumstances. People at risk of anaphylaxis must always carry their ASCIA Action Plan and their adrenaline autoinjector (EpiPen®) with them at all times. When accidental exposure occurs follow instructions on your ASCIA Action Plan for Anaphylaxis (ASCIA Action Plan). The best way to prevent anaphylaxis is to avoid whatever causes the allergic reaction.
Within minutes of exposure to the allergen, or ‘trigger’, a person can have potentially life-threatening symptoms such as breathing and/or heart symptoms. Anaphylaxis is a severe allergic reaction and requires immediate medical attention.
