Any one or more of the following symptoms may be present – these are often referred to as the ABC symptoms.
AIRWAY -swelling in the throat, tongue or upper airways (tightening of the throat, hoarse voice, difficulty swallowing)
BREATHING – sudden onset wheezing, breathing difficulty, noisy breathing
CIRCULATION – dizziness, feeling faint, sudden sleepiness, tiredness, confusion, pale clammy skin, loss of consciousness
Other symptoms that might be present include:
- a red raised rash (known as hives or urticaria) anywhere on the body
- a tingling or itchy feeling in the mouth
- swelling of lips, face or eyes
- stomach pain or vomiting.
These symptoms can also happen on their own. If you don’t have the ABC symptoms, the reaction is likely to be less serious and is not the same as anaphylaxis but watch carefully in case ABC symptoms develop.
