Anaphylaxis: Recognise It, Inject Adrenaline

Sudden multi-system reaction usually with skin involvement plus respiratory, cardiovascular, gastrointestinal or neurological signs.

Common triggers

Foods (peanut, tree nuts, shellfish), insect stings, medications (antibiotics, NSAIDs), latex, exercise-induced.

Immediate action

  • Intramuscular adrenaline (anterolateral thigh)
  • Call emergency services
  • Lay flat with legs raised (unless breathless)
  • Repeat adrenaline after 5-10 min if no response

After the reaction

Hospital observation 4-6 hours, allergy referral, two adrenaline injectors and an emergency action plan.

Antihistamines and steroids do not treat anaphylaxis — adrenaline is the only first-line therapy.
