Managing Allergies and Sudden Reactions

Allergies are incredibly common, affecting millions of people around the world. They occur when your immune system overreacts to a normally harmless substance, known as an allergen. 

While some allergies merely cause annoying symptoms, others can be severe and even life-threatening. Understanding your own allergies, or the allergies of those around you, can help prevent uncomfortable symptoms and potentially dangerous reactions.

Identifying Your Allergies

Knowing exactly what you’re allergic to is the first step in effective allergy management. If you experience regular allergy symptoms, or have had a severe allergic reaction (especially anaphylaxis), see an allergy specialist for an accurate diagnosis.

Common allergens include:

  • Foods: Peanuts, tree nuts, milk, eggs, shellfish, etc.
  • Environmental: Pollen, dust mites, mould, animal dander.
  • Medications: Penicillin and other antibiotics.
  • Insect stings: Bees, wasps, etc.

It’s important to remember that even if you’ve been exposed to something before without issues, the severity of allergic reactions can change over time.

Managing Day-to-Day Allergies

Once you know your allergy triggers, the focus shifts to minimising exposure and managing symptoms. Here are some strategies:

  • Avoidance: The most effective way to prevent reactions is to avoid your allergens. This might mean dietary changes, keeping your home as allergen-free as possible, or checking pollen counts.
  • Over-the-counter medications: Antihistamines and decongestants can often help relieve mild allergy symptoms like sneezing, a runny nose, and itchy eyes.
  • Seek further support: If your allergies are difficult to control, or if you experience any new or worsening symptoms, consult your GP or allergy specialist. They may recommend additional treatments or allergy testing.

Recognising Allergic Reactions

Allergic reactions can range from mild to severe. Typical symptoms include:

  • Itching in the mouth, throat, eyes, or skin
  • Hives (raised, itchy red bumps)
  • Swelling of the face, lips, tongue, or throat
  • Runny nose, sneezing
  • Wheezing, difficulty breathing
  • Stomach cramps, nausea, vomiting

Even if a reaction seems mild, it’s important to seek medical advice if you’re unsure, as symptoms can sometimes worsen quickly.

Unexpected Reactions

If you are exposed to a potential allergen for the first time (like a food you’ve never eaten or an insect sting), be watchful for possible allergic reactions. Seek immediate medical attention if you experience any of the following:

  • Difficulty breathing or swallowing
  • Dizziness, fainting, or feeling lightheaded.
  • Rapid heartbeat
  • Widespread hives or swelling

After such a reaction, seeing an allergy specialist for testing is essential to identify the cause and plan for the future.

Emergency Preparedness for Known and Unexpected Reactions

For known allergies:

  • Adrenaline auto-injector: If you have a history of severe allergic reactions (anaphylaxis), your doctor will likely prescribe an adrenaline auto-injector (such as an EpiPen). Always carry it with you.
  • Educate others: Ensure family, friends, co-workers, or teachers know how to recognise a severe reaction and use your auto-injector in an emergency.
  • Medical alert jewellery: Consider wearing a bracelet or necklace detailing your allergies.
  • Action Plan Work with your doctor to create an allergy action plan that outlines your allergies, emergency medication, and contact information.

For unexpected reactions:

  • Be vigilant: Monitor yourself or your loved one closely for signs of a worsening reaction after exposure to a potential new allergen.
  • When in doubt, seek help: Err on the side of caution and get immediate medical attention if you experience any concerning symptoms.
