EpiPen is an ijnection which is used in emergency situations to treat very severe allergic reactions.

The auto injector contains adrenaline (epinephrine), which counteracts the dangerously low blood pressure and other symptoms of anaphylactic shock.

Adrenaline (epinephrine) causes the blood vessels to constrict and opens the airways of the lungs to make breathing easier. You are able to buy an epipen through our online clinic service.

Both Epipen 0.3mg & Epipen Junior 0.15mg are available.

  • How to use an EpiPen

    It’s extremely important that you know how to correctly use your EpiPen, especially if you’re at high risk of anaphylactic shock due to a severe allergy. You should also tell your family, friends or colleagues how to use the EpiPen, and where you store it, so they’re prepared in an emergency. 

    If you’ve been stung by an insect, you should try to remove the stinger with your fingernails but do not squeeze, pinch or push it deeper into the skin. If possible, you should put an ice pack on the area of the sting. For allergic reactions caused by food, remove any remaining food from your mouth immediately. 

    Each EpiPen Auto-Injector will deliver one 0.3mg dose of adrenaline. Sometimes, a single dose may not be enough to reverse the effects of anaphylaxis and you may need to use another one within 5-15 minutes after the first injection. For this reason, you should carry two EpiPens with you at all times. 

    Hold the EpiPen by the middle, never by the ends. Never put your thumb, fingers, or hand over the orange tip, and do not remove the blue safety cap until you’re ready to use the EpiPen. Follow the instructions below on how to correctly use an EpiPen in the case of a severe allergic reaction: 


    • Hold the EpiPen in your dominant hand with your thumb nearest the blue cap. Form a fist around the EpiPen with the orange tip facing down. 
    • With the other hand, pull off the blue safety cap. 
    • Hold the EpiPen at a distance of approximately 10cm away from the outer thigh. The orange tip should point towards the outer thigh. Note: you don’t need to remove clothing to administer the pen into the thigh. 
    • Jab the EpiPen firmly into the outer thigh at a right angle and listen for a click. 
    • Hold firmly against the thigh for 3 seconds - the injection is now complete and the window of the injector should be obscured. 
    • The EpiPen should then be removed and safely discarded. The orange needle cover will extend to cover the needle.
    • Dial 999 for an ambulance and state anaphylaxis. When paramedics arrive, make sure you tell them that an EpiPen has been administered. 

    In the case of an overdose or an accidental injection of adrenaline, your blood pressure may rise sharply and you will need to seek immediate medical attention. 

    You must never reuse an EpiPen, even if there appears to be medicine left in the injector. If you need to administer another injection, you must use a new one. 

  • What are the symptoms of anaphylaxis?

    Anaphylaxis, commonly referred to as an anaphylactic shock, is a severe and life-threatening type of allergic reaction. It is a medical emergency and you must call 999 if you or someone else suddenly starts to display the following symptoms: 

    • Feeling lightheaded or faint
    • Breathing difficulties (such as fast or shallow breathing) 
    • Wheezing 
    • A fast heartbeat
    • Clammy skin
    • Confusion and anxiety
    • Collapsing or losing consciousness 

    In some cases, these symptoms may be accompanied by other allergy symptoms depending on the trigger. These may include: 

    • Itchy, raised rash (hives)
    • Feeling or being sick
    • Swelling of the lips, throat, tongue hands or feet
    • Stomach pain 

    These symptoms will occur within minutes of exposure to an allergen. If you or someone else has these symptoms, you should follow these steps: 

    • Use an adrenaline auto-injector like an EpiPen if you have one, providing you know how to use it correctly. 
    • Call 999 for an ambulance immediately, even if symptoms start to ease. Tell the operator that you suspect anaphylaxis. 
    • Remove any trigger if possible, such as an insect stinger stuck in the skin. 
    • The person suffering from anaphylaxis should lie down flat unless they’re unconscious, pregnant, or having breathing difficulties. Unconscious patients should be placed on their side in the recovery position. 
    • Use the adrenaline injection again after 5 to 15 minutes if symptoms do not improve. 

Side Effects

Like all medicines, an EpiPen could cause side effects. Despite this, adrenaline injections are life-saving emergency treatments and should always be used in the case of anaphylaxis if possible. Some side effects may include: 

  • Irregular heartbeat (including palpitations or rapid heartbeats)
  • High blood pressure
  • Sweating
  • Nausea or vomiting 
  • Difficulty breathing
  • Paleness
  • Headache or dizziness
  • Hypertension 
  • Weakness 
  • Tremor 
  • Apprehension, nervousness, or anxiety 
  • Cardiomyopathy (rare)



When should an EpiPen not be used? 

There are no known reasons as to why anyone should not use an EpiPen during a life-threatening allergic reaction. This is a life-saving device that is incredibly important in preventing death during an anaphylactic shock. It is important, of course, to only use an EpiPen in the event of a serious allergic reaction. 

You should take special care with your EpiPen and speak to your doctor or PharmacyOnline.co.uk pharmacist for advice if:

  • You have heart disease - EpiPen may affect the medicines you are taking or bring on an attack of chest pain (angina).
  • You have an overactive thyroid. 
  • You have high blood pressure. 
  • You have diabetes. 
  • You are elderly, pregnant, or weigh less than 25kg (in children).
  • You have increased pressure in your eyes (glaucoma). 
  • You have severe kidney problems. 
  • You have a tumour in your prostate. 
  • You have high calcium levels or a low potassium level in your blood. 
  • You have Parkinson’s disease. 
  • You are taking any other medicines or herbal remedies, including those obtained without a prescription.
