  • What is an EpiPen®?

    What is an EpiPen®?

    EpiPen® is an auto-injector device which contains adrenaline and is only available on prescription from your doctor. It lets you inject an appropriate and immediate dose of adrenaline when you or the person you are caring for have an anaphylactic reaction, while you are waiting for the ambulance to arrive.

  • How does adrenaline work?

    How does adrenaline work?

    Adrenaline is the best treatment for anaphylaxis because it quickly starts to sort out the symptoms of anaphylaxis. It narrows your blood vessels so that your blood pressure can start to return to normal and relaxes your lungs and throat so you can breathe more easily.

  • What is the difference between EpiPen® and EpiPen® Jr?

    What is the difference between EpiPen® and EpiPen® Jr?

    They both contain adrenaline, but in different amounts. EpiPen® contains 0.3mg, and EpiPen® contains Jr 0.15mg. Selection of the appropriate dosage strength for the patient is determined by the prescribing physician according to patients body weight. 

    EpiPen® auto injector 0.3mg is recommended for adults weighing >25kg.

    EpiPen® Jr. auto injector 0.15mg is recommended for children weighing between 7.5 – 25kg. For children weighing more than 25kg, EpiPen® auto injector 0.3mg is recommended.

  • How should I use my EpiPen®?

    How should I use my EpiPen®?

    Remove the blue safety release cap, and then swing and jab the EpiPen® into your outer thigh to release the hidden needle and the dose of adrenaline. Hold the pen in place for 10 seconds, then remove it and massage the injection site for at least 10 seconds. The EpiPen® User Guide page has full instructions. It is best to practise regularly with a training device. You can order a trainer pen here* if you do not have one, or ask your doctor for one. *postage and packaging to be paid. UK only.

  • How will I know that my EpiPen® has worked and that I have received the adrenaline I need?

    How will I know that my EpiPen® has worked and that I have received the adrenaline I need?

    When you swing and jab the EpiPen® into your thigh, the needle and the dose of adrenaline will be released. After removing the EpiPen®, the orange end will extend to cover the needle and the viewing window will go dark. There will still be some adrenaline left in the pen, and this is perfectly normal. You will quickly start to feel that the adrenaline is working. Remember, each EpiPen® can only be used once.

  • Can EpiPen® be used through clothing?

    Can EpiPen® be used through clothing?

    Yes, even jeans. Take care to avoid hitting zips, buttons, buckles, seams and pocket contents.

  • After using my EpiPen® what should I do?

    After using my EpiPen® what should I do?

    Always seek medical attention. You must dial 999, ask for an ambulance and state ‘anaphylaxis’ (pronounced ‘anna-fill-axis’) immediately after administering the EpiPen®. Make sure you give your used pen to the paramedic. Remember to get a new EpiPen® as soon as possible.

  • There is an “air” bubble in my EpiPen®, is it still OK to use?

    There is an “air” bubble in my EpiPen®, is it still OK to use?

    The bubble is a type of gas called nitrogen, and it is perfectly normal to find it in an EpiPen®. Don’t worry about using your pen as the bubble will not interfere with how well it works.

  • When should I use my EpiPen®?

    When should I use my EpiPen®?

    Your doctor or nurse will tell you how to recognise the signs and symptoms of anaphylaxis, we have listed the most serious symptoms on the About Anaphylaxis page.

    If you think you have come into contact with your trigger, make sure you have your EpiPen® to hand and use it immediately if you start to experience serious symptoms. You must dial 999, ask for an ambulance and state ‘anaphylaxis’ (pronounced ‘anna-fill-axis’) immediately after administering the EpiPen®.

  • Is there a training device I can practise with?

    Is there a training device I can practise with?

    Yes, you can order a trainer pen here*. Practise as much as you can to make sure you know what to do in an emergency. The Trainer Pen is grey and works the same way as an EpiPen®, although there is no adrenaline and no needle.

    * postage and packaging to be paid. 

  • What should I tell family, friends and workmates?

    What should I tell family, friends and workmates?

    Tell them the signs and symptoms, where you keep your EpiPen® and how to use it. Show them this website, and how to inject using the trainer pen. You can also download and print information from My EpiPen® Resources page for them to keep.

  • How can I remember to replace my EpiPen® when it is due to expire?

    How can I remember to replace my EpiPen® when it is due to expire?

    Simply sign up for our Expiry Alert Service and we will send you text and/or email messages reminding you to visit your doctor or pharmacist in time to replace your EpiPen® before it expires.

  • What do I do if I notice that my EpiPen® is out of date?

    What do I do if I notice that my EpiPen® is out of date?

    Make sure you see your GP or pharmacist as soon as possible to get a new pen. Use our EpiPen® Expiry Alert Service to receive reminders when your pen is about to expire.

  • Can I register more than one EpiPen®?

    Can I register more than one EpiPen®?

    Yes. If they all have the same expiry date you only need to fill in one form. If they have different expiry dates, you need to fill in a different form for each one.

  • How should I store my EpiPen®?

    How should I store my EpiPen®?

    Adrenaline can be damaged by heat and direct sunlight, so always keep it in its hard carry case and away from very high or low temperatures.

  • Are there any precautions I should take with my EpiPen® before I go abroad?

    Are there any precautions I should take with my EpiPen® before I go abroad?

    Make sure that you have enough EpiPen® with you – it may be difficult and expensive to get replacement pens abroad. Organise this with your GP several weeks before.
    Airlines will often require a letter from your doctor to allow you to carry your EpiPen® with you onto the aircraft. Click on the link to print off a Travel Certificate for your doctor to fill in – make sure you get it done in good time before you travel. If you have a food allergy, you should also discuss meal options (if provided).

  • I am travelling to a very different climate to the UK and I wondered if my EpiPen® would still work properly?

    I am travelling to a very different climate to the UK and I wondered if my EpiPen® would still work properly?

    EpiPen® are sold all over the world and used in a variety of climates very different from ours in the UK. When travelling abroad, you should take the same care as you would in the UK and observe the storage recommendations in the package leaflet. Your EpiPen® should never be exposed to direct sunlight or very hot or cold temperatures for prolonged periods, and should never be refrigerated or frozen. It should always be kept in the case provided. It may also be worth contacting the airport from here you are travelling from and the company you are travelling with to see if there are special requirements they may have for travelling with specialist medicines.
