This is an iatroX educational summary of named Australia sources, not an official guideline. It does not replace the complete source documents, local policy, specialist advice or clinical judgement. Apply current TGA product information, PBS restrictions, state or territory law, local referral criteria, formulary and antimicrobial policy. A national recommendation does not create uniform service access.

Scope

Recognise acute illness involving airway, breathing or circulation, with or without skin signs, after a likely trigger as anaphylaxis requiring immediate treatment. Give intramuscular adrenaline into the outer mid-thigh without delay and repeat under the ASCIA protocol when response is inadequate. This summary is limited to the population, decisions and escalation boundaries stated in the named source.

The Bottom Line

  • Recognise acute illness involving airway, breathing or circulation, with or without skin signs, after a likely trigger as anaphylaxis requiring immediate treatment.
  • Give intramuscular adrenaline into the outer mid-thigh without delay and repeat under the ASCIA protocol when response is inadequate.
  • For people who are pregnant, position with left lateral tilt while maintaining standard adrenaline treatment.
  • Position the person appropriately, avoid sudden standing, call emergency services and support airway, breathing and circulation; antihistamines do not treat shock.

Practical clinical workflow

1

Topic-specific assessment action

Recognise acute illness involving airway, breathing or circulation, with or without skin signs, after a likely trigger as anaphylaxis requiring immediate treatment.
2

Topic-specific diagnostic action

Position the person appropriately, avoid sudden standing, call emergency services and support airway, breathing and circulation; antihistamines do not treat shock.
3

Topic-specific management action

Observe in an appropriate facility according to severity and risk, document the suspected trigger and arrange ASCIA action plan and injector education.
4

Topic-specific follow-through

Beta blockers can complicate response but do not contraindicate intramuscular adrenaline; refractory shock needs expert escalation.

Safety boundaries and escalation

  • Refer for allergy evaluation and advise trigger avoidance, but do not delay emergency adrenaline while seeking diagnostic certainty or intravenous access.
  • Record the event in the medical record and teach injector carriage and technique with a trainer device before discharge.

Implementation

The named source is national or binational guidance used in Australia, but referral access, public-health directions, formularies and funded services can still differ by state, territory and health service. Check current TGA product information for medicines. Offer culturally safe care and use the NACCHO鈥揜ACGP National Guide where Aboriginal and Torres Strait Islander preventive or chronic-care recommendations differ.
