Allergic Reaction

Anaphylaxis is usually triggered by allergens such as peanuts, tree nuts, shellfish, milk, eggs, insect stings, or certain medicines like antibiotics. Some people are diagnosed with anaphylaxis after specialist testing by an allergy clinic.

Because it can be life-threatening, anyone diagnosed with anaphylaxis should always carry two adrenaline auto-injectors.

Anaphylaxis often starts within minutes of exposure. Symptoms may include swelling of the lips, tongue or throat, difficulty breathing or swallowing, sudden hoarseness, wheezing, dizziness, or collapse. Skin symptoms such as hives or redness may also appear.

If you ever think you are experiencing anaphylaxis, use your EpiPen immediately and call 999. Do not wait to see if symptoms improve on their own.

The only emergency treatment for anaphylaxis is adrenaline, given by an auto-injector such as an EpiPen, Jext or Emerade. After using your injector, you must call 999 for an ambulance, as symptoms can return and further treatment may be needed in hospital.

People who have already been diagnosed with anaphylaxis are advised to:

Always carry two auto-injectors with them
Make sure friends, family and colleagues know how to use them
Check expiry dates and replace pens before they run out

Our service can provide repeat supplies of an EpiPen for patients who have already been diagnosed by a doctor or allergy specialist. We cannot provide initial diagnosis or emergency treatment.

Always read the patient information leaflet that comes with your injector.

If you use your pen, call 999 immediately. If you are unsure whether to use it, it is safer to use it and seek urgent help.
