Product information

EpiPen is an immediate response, injectable medication intended for use during anaphylactic reactions, caused by allergies. It is a branded adrenaline auto-injector (AAI). It is supplied in an applicator similar in shape to a pen, which contains a needle inside. This is jabbed into the thigh when required, and releases a dose of adrenaline into the body to avert symptoms. EpiPen is made by Mylan, and is available to buy from our online pharmacy in the UK.

In some cases, an episode of anaphylactic shock may require two pens to be administered, 5-15 minutes apart. For this reason, it is advisable for patients who have been told to carry a pen to have access to two at all times.

The different types of allergic reactions

Allergic reactions tend to vary greatly in their severity. Some people with allergies such as hay fever may experience mild to moderate symptoms after coming into contact with pollen, such as coughing, sneezing or puffing around the eyes. Others, such as those who are allergic to certain soaps or cosmetics, may develop skin conditions similar to dermatitis. These types of allergic reactions can be uncomfortable, are not usually life-threatening and can be treated with antihistamines.

However, anaphylactic reactions caused by coming into contact with an allergen can be fatal in some cases. These are more typically very sudden in nature, and can be triggered by insect stings, certain foods such as nuts or shellfish, or sometimes medication. The most common signs of an anaphylactic response include breathing difficulties, the appearance of a rash which may be very itchy, swelling in the face (especially in the eyes and lips) or the throat, wheezing, and in some cases, loss of consciousness. Sometimes, symptoms can be so severe that they can lead to heart failure.

Why does anaphylaxis occur?

Anaphylaxis occurs when the immune system responds drastically to the stimuli provided by an allergen, even though it may be harmless. Essentially, the immune system is attempting to protect the body from the allergen, which is perceived as a threat, by releasing certain chemicals. These cause a severe, inflammatory response in the body, causing blood vessels to widen, thereby dramatically dropping blood pressure. This leads to the swelling of tissue and the onset of the above symptoms.

How does EpiPen work? 

Broken down, the name epi pen refers to both the name of the active ingredient, and the way the treatment is delivered. EpiPen contains an adrenaline called epinephrine, which works quickly to shrink blood vessels and prevent them from dilating. This helps to manage blood pressure, enabling the heart to maintain normal function; and reduces the swelling of tissue, including in the throat, facilitating easier breathing.

In addition to the standard pen for adults, Mylan has also developed EpiPen Jr. This is a reduced dose version, which is used to treat anaphylaxis in children with a weight of 15-30kg. It is administered in exactly the same manner as the adult pen, and performs an identical function in the body. However, please note that this is not available to buy from our UK pharmacy.

Can I buy EpiPen adrenaline auto injectors online?

If you are an adult looking to renew your EpiPen prescription, you can do so through our online pharmacy service. Our consultation facility has been designed to enable you to order the treatment you need safely and efficiently. Each order is assessed by a GMC registered doctor, before being dispensed at our UK pharmacy.

Please note that once your EpiPen has gone past its expiry date, it will need to be replaced. Our pharmacy provides a service notifying patients of when an EpiPen bought through us is about to expire.

A doctor or nurse will typically show you how to use EpiPen after you have been diagnosed with a severe allergy. If you haven’t been shown, you should make an appointment with your GP or allergy specialist as soon as possible.

Even if you have been shown, you should take the time to familiarise yourself with the instructions provided. Doing so will help you to understand how to use this treatment properly in the event that you will need to.

  1. The standard issue dose for adults is 0.3mg.
  2. After coming into contact with an allergen, take measures to quickly remove it from the body as much as you can. For example, a stinger from a wasp or bee sting should be picked out as soon as possible. Foods which cause allergic reactions should be swiftly removed from the mouth.
  3. EpiPen should be applied as soon as you notice the signs of an allergic reaction. 
  4. This can be done through clothing if the situation requires it.
  5. Administer the EpiPen to the outside of the thigh.
  6. It should be struck in firmly from a distance of 10cm, at a 90 degree angle.
  7. Apply to the muscle. Do not inject it intravenously, as this may cause serious harm.
  8. The plunger inside will activate and release the adrenaline.
  9. Hold the injector in place for around 10 seconds before carefully removing.
  10. The dose has been administered once the window on the EpiPen is covered.
  11. Massage your leg for 10 seconds after removing the needle.
  12. You will need to seek medical attention after using EpiPen to make sure your symptoms do not return or escalate. Call 999, or get someone else to do it for you.
  13. Detailed directions on how to use the application device itself can be located in the patient information leaflet. 
  14. If allergic symptoms persist, you should administer a second dose from another EpiPen if your doctor has deemed this as a suitable course of action beforehand. Please note that each pen only contains one dose. For a second dose, another pen will be required.
  15. As such, it is advisable to carry or have access to more than one EpiPen at a time.

Please note that the above constitutes only a summary of the directions you will need to follow when carrying and using this product. Consult the leaflet supplied for more comprehensive information.

Can I still drink alcohol?

This product is an instant treatment for allergic reactions, and its effectiveness is not likely to be reduced by alcohol. However, generally, you should avoid drinking too much alcohol, as doing so may put you in a position where you are unable to administer the treatment yourself, if and when required.

The consumption of alcohol should be avoided immediately following use, and medical advice should be sought right away.

Will I still be able to drive?

You are unlikely to be able to drive safely if you are experiencing anaphylactic shock. We would therefore not recommend doing so after applying this product. Call an ambulance to take you to hospital, or get someone else to.

Can I take the medicine while pregnant?

Inform your doctor during consultation if you are pregnant or breastfeeding, and they will advise you.

You should still use this medication if you are pregnant and experience anaphylaxis, to protect your child’s life and your own.

How should I store it?

Keep in a safe environment below 25°C. Do not put it in the refrigerator or freeze it. Store it in the outer container to protect it from excessive sources of light. Check the fluid inside the glass cartridge in the EpiPen at regular intervals. It should be clear and colourless. If it is not, replace it.

We provide a notification service for when an EpiPen purchased through our site is due to go out of date, and require replacement.

Am I allergic to anything in the medicine?

This item contains: adrenaline, sodium chloride, sodium metabisulphite, hydrochloric acid, and water for injections.

Is it available over-the-counter?

You will need a prescription in order to buy EpiPen.

If you have been advised by a doctor to carry an EpiPen and have already been shown how to use it, you can order this item from our UK pharmacy when it is in stock. Our consultation facility enables a doctor to draw up a prescription for you. At the present time however, EpiPen is not available. 

How long will EpiPen be out of stock for?

It is not clear at this time when EpiPen will be available (it is out of stock nationally). We will update this page when it becomes available again. 

In the meantime, there are alternative adrenaline pens available, such as Jext and Emerade.

Is it right for me?

If you have a severe allergy and are at risk from anaphylactic reactions, then having the right protection is absolutely crucial.

Talk to your doctor or consultant allergist to find out more about this treatment if you have not been shown how to use it before.

How can I order EpiPen online? 

If you have an anaphylactic allergy, and a doctor or nurse has demonstrated to you how to use an adrenaline pen previously, you can usually order EpiPen using our online consultation service. 

Each case is assessed by a doctor or UK pharmacy prescriber to ensure patient safety, and approved orders are dispensed at our GPhC-registered pharmacy.
