What is anaphylaxis?

Anaphylaxis is a severe allergic reaction that annually causes 20 deaths in the UK. Anaphylaxis is not a common condition, but people of all ages can be affected. The leading causes of an allergic reaction include certain foods, insect stings and medicines. People with other allergic reactions, including asthma and eczema, are more at risk of anaphylaxis.

An anaphylactic reaction can be life threatning, causing breathing problems, irregular heartbeat, skin rash and may require medical attention. Anaphylaxis treatments include different adrenaline auto injector brands, which the patient himself can also administer. With a quick response, most people make a full recovery.

Allergies are more common than you think. In fact, the number of people suffering from allergies may exceed 2 million in the UK. Fortunately, it is easy to handle allergies in most cases with appropriate lifestyle changes and precautions.

However, some people exhibit signs of extreme allergic reaction, which is not so easy to handle. When they get exposed to an allergen, they may experience a situation that is potentially life threatening. As a result, they experience a physical condition called anaphylaxis, in which their immune system releases certain chemicals that flood the body. When experiencing anaphylaxis, your blood pressure suddenly drops, and the airways become narrow, creating blockages to normal breathing.

What are the symptoms of anaphylaxis?

An anaphylactic reaction occurs as a result of coming in contact with a substance you have an extreme allergic reaction to. Its symptoms may include one or more of the following;

  • Feeling too hot or flushed
  • A sensation of having a lump in the throat or difficulty swallowing
  • The sudden appearance of skin disorders, like rashes, hives, paleness, etc.
  • Nausea or vomiting
  • Diarrhoea
  • Fast or irregular heartbeat
  • Abdominal pain
  • Runny nose
  • Wheezing or difficulty breathing
  • Swollen tongue or lips
  • Tingling hands, feet, scalp, or mouth

An anaphylactic reaction may progress to anaphylactic shock if left untreated. Its symptoms may include;

  • Difficulty breathing
  • Confusion
  • Dizziness
  • Fatigue or a sudden feeling of weakness
  • Falling unconscious

If you experience a severe allergic reaction, call 999 immediately and ask for an ambulance.

What are the causes and risk factors of anaphylaxis?

Typically, anaphylaxis is caused by an overreaction of the immune system by coming into contact with something your body is severely allergic to. In some cases, anaphylaxis can progress to a full-blown anaphylactic shock. Common triggers for severe allergic reactions are;

  • Certain medicines, like penicillin
  • Animal hair, like cats or dogs
  • Certain foods, like nuts, shellfish, milk, or eggs
  • Insect stings
  • Compounds used in immunotherapy
  • Latex

There are some rare cases when simple exercise or aerobic activity may trigger anaphylaxis. In other rare cases, the cause of anaphylaxis remains unknown, making it idiopathic. If you are unclear on what triggers your symptoms, you may need to consult your local GP to run a full battery of tests to identify your allergen.

The potential occurrence of anaphylaxis may increase if you have previously suffered from an anaphylaxis reaction, have existing allergies, or have a family history of anaphylaxis.

What to do in cases of anaphylactic shock?

Generally, most people learn to avoid their allergy triggers. However, the risk of accidentally eating a peanut or shellfish is always there. Kids seem to be especially vulnerable to allergies and resulting allergic reactions. If you experience anaphylaxis, please seek emergency treatment immediately.

If you carry an epinephrine auto injector or EpiPen with you, immediately use it at the onset of symptoms. Also, do not take any other oral medicine when having difficulty breathing. Even if your symptoms subside after taking the EpiPen auto injector, please seek immediate medical attention anyway because there is a risk of the symptoms recurring as soon as the medicine wears off. Due to the chance of recurring symptoms, always carry two auto injectors with you.

If anaphylaxis occurs because of a trigger, please remove it immediately. For example, if an insect sting causes the symptoms, immediately remove it from your body. Be very careful when removing the stinger, and make sure to remove it all.

If someone is experiencing an anaphylactic reaction in front of you, please do the following;

  • Call 999 for a medical emergency
  • Get the patient in a comfortable position
  • Elevate their legs to ensure the blood keeps flowing to the vital organs
  • If available, use an EpiPen auto immediately
  • If necessary, perform CPR until the medical team arrives

How is anaphylactic shock treated with EpiPen?

The best method of anaphylaxis treatment is the injectable treatment, injecting epinephrine (adrenaline) immediately after the onset of symptoms. It can reduce the severity of the symptoms and allergic reactions.
When experiencing severe allergic reactions, every passing second matters. That’s why acting without hesitation in administering appropriate treatment is vital to treat severe allergic reactions. In addition, if you have experience with an episode, you may have gotten a prescription for an auto injector in case of potential future attacks.
EpiPen auto injector is the ideal first-line anaphylaxis treatment. The device is pre-filled with the adrenaline necessary to treat severe allergic reactions. For the sake of convenience, the medicine is designed to be self-injected or administered by a carer. It takes effect immediately. It means that you may not have to wait for an ambulance or medical personnel to arrive to treat the problem. However, it is advisable to call 999 for anaphylaxis treatment regardless of emergency EpiPen auto injector administration.

How does EpiPen work?

When experiencing severe allergic reactions, certain chemicals flood into your system in response to the shock of an allergen. It causes the blood pressure to drop suddenly and the airways to narrow, causing breathing problems. The adrenalin administered through an EpiPen auto injector works to counteract this dangerous and potentially fatal reaction. The epinephrine first constricts the blood vessels to reduce swelling, in addition to increasing blood pressure. It also works to relax the lungs and throat, making it easier to breathe properly. Lastly, it stops the further release of chemicals causing the reaction in the body and prevents the adverse reaction from continuing.

Can I buy an EpiPen for anaphylaxis treatment online?

You can buy an EpiPen for the treatment of anaphylaxis online in UK. It comes in packs of 1 or 2 adrenaline pens. Typically, adrenaline auto injectors are prescribed by your local GP after reviewing your need for them. You can also complete a quick assessment form at Click Pharmacy, a UK registered pharmacy. If it suits your condition, you will be prescribed an auto injector, and you can order adrenaline pens to be delivered to your doorstep in discreet packaging through Royal Mail 1st class or next day delivery service.

Patient information leaflet

It is always vital to read the patient information leaflet before starting your treatment.

What is the difference between Epipen and Jext?

Both auto injectors are life saving medication for emergency situation for allergic reaction that can be fatal. Anaphylactic shock occurs whenever the body is exposed to something it is allergic to. In order to protect itself from the allergen, the body releases strong chemicals into the bloodstream. Due to these chemicals, some frightening symptoms can range from raised skin rash to swelling of the lips and even loss of consciousness. These severe symptoms of allergic reaction can take place in a second. In addition, such shocks can result in health complications.
Jext and Epipen are essentially the same. However, the way they are administered is slightly different. If, in a situation, the effects of the allergic reaction do not subside after the single dose, then use a second dose after 5 to 10 minutes. 

How common is anaphylaxis?

Anaphylaxis is continuing to grow. More and more people are getting diagnosed every day. However, it is life threatening but not common. It is still considered a rare condition. It is a fact that people of all ages can be affected by this severe form of allergic reaction. In particular, people with other allergic conditions, such as asthma or the allergic skin condition known as atopic eczema, are at high risk of developing anaphylaxis.

How is anaphylaxis diagnosed?

In general, anaphylaxis is diagnosed whenever individuals extensively discuss their past allergic reactions with their GPs. In addition to this, you can get yourself checked for anaphylaxis if you have any suspicion to believe that you might have the condition. Therefore, it is crucial to discuss your case with your GP, especially if you have had a severe allergic reaction in the past.

Can anaphylaxis lead to other problems?

If left unmanaged or untreated, anaphylaxis can lead to other health complications. Of course, it is vital to remember that the condition is a problem in itself. A reaction to other issues causes anaphylaxis – for instance, it may be triggered if your body wrongly perceives something to be a threat. Since it is extremely severe, it should be avoided wherever possible.

However, if you know that you are at constant risk of anaphylaxis, it is advised to always carry your chosen treatment with you.
