Anaphylaxis: Emergency Recognition & Treatment of Severe Allergic Reactions
A clear guide to anaphylaxis, a severe, life-threatening allergic reaction that needs immediate emergency treatment.
Treatment usually begins with
Emergency Assessment
Immediate Adrenaline
Airway & Circulation Support
Observation & Follow-up
Emergency treatment starts with immediate adrenaline and airway support, followed by a period of observation to ensure symptoms don't recur.
You may need this evaluated if...
This is a medical emergency requiring immediate action when someone shows:
- Sudden swelling of the face, lips or throat after exposure to an allergen
- Difficulty breathing or wheezing after a possible allergic trigger
- A widespread rash with dizziness or fainting
- Rapid onset of symptoms after a food, medication, or insect sting
Prompt recognition and immediate adrenaline treatment are highly effective at reversing anaphylaxis, and emergency teams are equipped to manage it quickly.
What is Anaphylaxis & Severe Allergic Reactions?
Anaphylaxis is a severe, rapidly progressing allergic reaction that can affect breathing and circulation within minutes, requiring immediate adrenaline treatment and emergency care to prevent a life-threatening outcome.
Symptoms Progress Very Quickly
Anaphylaxis can go from mild symptoms to a life-threatening reaction within minutes.
Adrenaline Is the Immediate Treatment
Prompt adrenaline injection is the most effective way to reverse the reaction.
A Wide Range of Possible Triggers
Foods, medications, insect stings and other exposures can all cause anaphylaxis.
Observation Continues After Initial Treatment
A period of monitoring follows treatment, since symptoms can occasionally recur.
Common Symptoms
- Swelling of the face, lips, tongue or throat
- Difficulty breathing or wheezing
- A widespread rash or hives
- Dizziness, fainting or a rapid heartbeat
- Nausea, vomiting or abdominal pain
What Increases Your Risk
A combination of situational, environmental and health factors can increase the likelihood of this emergency.
How It Is Diagnosed
A rapid, structured assessment confirms the diagnosis and guides immediate treatment.
Clinical Assessment
Rapid recognition of characteristic symptoms guides immediate treatment.
Airway & Breathing Assessment
Evaluates the severity of airway or breathing involvement.
Blood Pressure & Circulation Monitoring
Assesses the degree of circulatory involvement.
Trigger Identification
Understanding the likely trigger helps guide future prevention.
Treatment Approaches
Emergency Stabilization
- Immediate adrenaline injection as the primary treatment
- Oxygen and airway support as needed
- Additional medication to manage ongoing symptoms
- A period of observation to monitor for recurrence
Advanced & Surgical Care
Surgery has no role in anaphylaxis; treatment is entirely medical, followed by allergy evaluation to guide future prevention.
Treatment decisions are made rapidly based on your vital signs, injury pattern and overall condition, not a single protocol.
Know When to Act
Recognising these signs and reaching emergency care immediately can be lifesaving.
Book an Assessment
Schedule a consultation for a routine evaluation or follow-up concern.
- A mild, localised allergic reaction without breathing difficulty, seeking evaluation
Seek Urgent Care

- Swelling of the face or throat, breathing difficulty, or dizziness after a possible allergen exposure
