Signs and Symptoms of an Anaphylactic Reaction
Introduction
Anaphylaxis is a life-threatening allergic reaction that requires immediate medical intervention. If not treated quickly, it can lead to anaphylactic shock, unconsciousness, and even death.
Recognising the early warning signs of anaphylaxis and taking swift action—such as using an EpiPen (adrenaline auto-injector)—can save lives.
This guide explains the mild and severe symptoms of anaphylaxis, what to do in an emergency, and how to stay prepared.

Mild Symptoms of Anaphylaxis
Anaphylaxis doesn’t always begin with severe symptoms. In some cases, early signs may appear as mild allergic reactions before rapidly progressing into a life-threatening emergency.
Early Signs to Watch For:
- Itchy skin or hives (red, raised patches that spread).
- Mild swelling of the lips, eyes, or face.
- Nausea, vomiting, or stomach cramps.
- Tingling sensation in the mouth or throat.
If any of these symptoms appear in someone with known severe allergies, monitor closely and be prepared to use an EpiPen if symptoms worsen.
Severe Symptoms of Anaphylaxis
If left untreated, anaphylaxis can progress rapidly, affecting the airways, heart, and circulation. This can result in anaphylactic shock, a medical emergency that requires immediate treatment.
Serious Symptoms of Anaphylaxis Include:
1. Breathing Difficulties
- Tightness in the chest and throat.
- Wheezing or struggling for breath.
- Swelling of the tongue and throat, blocking the airway.
2. Cardiovascular Symptoms (Shock)
- A sudden drop in blood pressure, causing dizziness or fainting.
- Weak, rapid pulse.
- Pale or clammy skin.
3. Loss of Consciousness
- Feeling lightheaded, confused, or disoriented.
- Collapse or becoming unresponsive.
4. Other Severe Symptoms
- Severe nausea, vomiting, or diarrhoea.
- Hoarse voice or difficulty speaking.
- Intense flushing or swelling of the face.
If any of these symptoms appear, administer an EpiPen immediately and seek emergency medical help.
What to Do in an Anaphylactic Emergency
Anaphylaxis can escalate within minutes, so immediate action is critical. Follow these life-saving steps:
Step 1: Administer an EpiPen (Adrenaline Auto-Injector)
- Remove the blue safety cap.
- Place the orange tip against the outer thigh (can be injected through clothing).
- Press firmly until you hear a click.
- Hold in place for 3-5 seconds.
- Remove and massage the injection site for 10 seconds.

Step 2: Call Emergency Services (999 in the UK)
- Even if symptoms improve after using an EpiPen, medical supervision is required.
- Anaphylaxis can cause a secondary reaction (biphasic anaphylaxis) hours later.
Step 3: Keep the Person Comfortable
- Lay them flat on their back with legs elevated.
- If they struggle to breathe, let them sit upright.
- Stay with them until medical help arrives.
Step 4: Use a Second EpiPen if Necessary
- If symptoms do not improve after 5-10 minutes, use a second EpiPen.
Being prepared and acting fast can save a life in an anaphylactic emergency.
