    How to use or administer an EpiPen

    An EpiPen is a lifesaving device designed to treat severe allergic reactions, also known as anaphylaxis. Knowing how to use it properly can make all the difference in an emergency. This guide will walk you through the steps to administer an EpiPen effectively, as well as provide tips on preventing and managing anaphylaxis. Read the product instruction manual, to know the steps to administer it properly.

    Key Takeaways

    Know When to Use an EpiPen

    • Use an EpiPen immediately if someone shows symptoms of anaphylaxis such as throat swelling, difficulty breathing, or severe hives.

    • After administering, call 999 for emergency assistance.

    Follow Proper Steps for Administration

    • Remove the safety cap, place the orange/black tip against the outer thigh (even through clothing), and press firmly until a click is heard. Hold for 10–15 seconds.

    • If symptoms persist after 5 minutes, administer a second dose using a new EpiPen.

    Prevent and Be Prepared for Anaphylaxis

    • Identify and avoid triggers like certain foods, insect stings, or medications. Always carry an EpiPen and an emergency kit.

    • Replace expired EpiPens promptly, but in an emergency, a recently expired EpiPen can still be used if the liquid is clear and particle-free.

    What is an EpiPen?

    An EpiPen is an auto-injector that delivers a dose of adrenaline (epinephrine). Adrenaline helps to quickly reverse the symptoms of anaphylaxis by reducing swelling, relaxing airway muscles, and improving blood flow.

    When to Use an EpiPen

    Use an EpiPen if someone is experiencing symptoms of anaphylaxis, including:

    • Swelling of the throat or tongue.

    • Difficulty breathing or wheezing.

    • Severe hives or rashes.

    • Feeling faint or dizzy.

    • A rapid or weak pulse.

    Anaphylaxis is a medical emergency. Administer an EpiPen immediately and call 999 for further assistance.

    How to Administer an EpiPen

    Follow these steps to ensure the EpiPen is used correctly:

    1. Prepare the EpiPen

    • Remove the EpiPen from its case.

    • Pull off the safety cap (this is typically blue).

    2. Hold the EpiPen Correctly

    • Grip the EpiPen firmly in your hand, ensuring your thumb is not over either end.

    • The orange or black tip contains the needle and must face down towards the thigh.

    3. Administer the Injection

    • Place the EpiPen against the outer thigh. It can be used through clothing.

    • Avoid injecting near thick seams (e.g., on jeans).

    • Push the EpiPen firmly until you hear a click. This indicates the needle has been activated.

    • Hold the EpiPen in place for 10–15 seconds to ensure the full dose is delivered.

    4. Post-Injection Steps

    • Remove the EpiPen and gently massage the injection site for 10 seconds to aid absorption.

    • Use the needle guard to cover the exposed needle before safely disposing of the device.

    • Write down the time of administration on the EpiPen or inform medical responders.

    • If symptoms persist after 5 minutes, a second injection may be given using a new EpiPen.

    Understanding EpiPen Variants

    EpiPens are available in two types:

    • Green EpiPen: For children under 5 years old.

    • Orange EpiPen: For individuals 5 years and older.

    Ensure you have the correct EpiPen for the person requiring treatment.

    Preventing Anaphylaxis

    Anaphylaxis can often be avoided by identifying and steering clear of allergens. Common triggers include:

    • Food: Peanuts, shellfish, dairy, and eggs.

    • Medications: Antibiotics, aspirin, and certain vaccines.

    • Insect Bites: Bee or wasp stings.

    • Latex: Found in gloves or medical supplies.

    Tips for Prevention

    • Notify healthcare providers of any allergies.

    • Wear protective clothing and use insect repellent if allergic to stings.

    • Always read food labels carefully if you have food allergies.

    • Carry an emergency kit, including an EpiPen, at all times.

    What to Do in an Emergency

    If you or someone else experiences anaphylaxis:

    1. Administer an EpiPen immediately.

    2. Call 999 and explain the situation.

    3. Lay the person flat (unless they are vomiting or experiencing breathing difficulties, in which case they should sit up).

    4. Monitor their condition and be prepared to give a second dose if necessary.


    Using an Expired EpiPen

    In emergencies where only an expired EpiPen is available:

    • Check the liquid: If it’s clear and free from particles, it may still be effective.

    • Minimal risk: Using a recently expired EpiPen carries minimal risk compared to the danger of untreated anaphylaxis.

    Always replace expired EpiPens promptly to ensure reliability.

    Final Thoughts

    Knowing how to use an EpiPen and recognising the signs of anaphylaxis can save lives. Make sure you and those around you are familiar with its use and have an emergency plan in place. Always keep your EpiPen accessible, and replace it before it expires to ensure you’re prepared for any situation. If you suspect anaphylaxis, don’t wait—act fast and seek immediate medical help.
