Topics
Allergic reactions are sensitivities to allergens that come in contact with the nose, eyes, respiratory tract, skin and gastrointestinal tract. They may be inhaled into the lungs, ingested, or injected.
Common allergens include food (peanuts, milk, eggs, wheat, soy, shellfish), airborne substances that you breathe in, medications (antibiotics, nonsteroidal anti-inflammatory drugs, insulin, chemotherapy drugs), venom from stinging insects (bees, hornets, wasps, yellow jackets), and latex (rubber gloves, condoms, bandages, rubber balls).
Symptoms of an allergic reaction
Common symptoms of an allergic reaction include generalised hives, pruritus, or flushing, nasal congestion, rashes, and watery, red eyes.
Symptoms of moderate to severe reaction include swollen lips-tongue-uvula, feeling of fullness of lump in the throat, breathlessness, wheezing, abnormal, high-pitched breathing, severe crampy abdominal pain, repetitive vomiting, diarrhoea, dizziness / fainting.
Anaphylaxis
Anaphylaxis is a severe allergic reaction that requires immediate medical attention. It can be caused by food, insect bites or medications.
Epinephrine is the first and most crucial treatment for anaphylaxis, and it should be administered as soon as anaphylaxis is identified to prevent the development of life-threatening symptoms.
Early administration of epinephrine can reverse symptoms of anaphylaxis. Use the epinephrine injection exactly as prescribed by the doctor.
How to use an EpiPen on yourself
- Hold the pen in your dominant hand, with the blue end facing upwards and the orange tip pointing downwards. “Blue to the sky, orange to the thigh”.
- Remove the blue safety cap.
- Place the EpiPen against the outer thigh. Hold the EpiPen at a 90-degree angle, approximately 10 cm distant.
- At a right angle, inject the EpiPen into the outer thigh. Hold securely for 3 seconds, then remove and discard safely.
How to use an EpiPen on someone else
- If you notice someone experiencing severe allergic reactions (anaphylaxis) and have an EpiPen, stay calm and quickly assess the person’s condition. Call an ambulance immediately.
- Before administering the EpiPen, if the person is conscious and able to communicate, ask for consent to administer the epinephrine.
- With the EpiPen in your hand, remove the blue safety cap.
- Place the EpiPen against the outer thigh. Hold the EpiPen at a 90-degree angle, approximately 10 cm distant.
- At a right angle, inject the EpiPen into the outer thigh. Hold securely for 3 seconds, then remove and discard safely.
In an emergency, epinephrine can be injected through clothing and given as an injection into the middle of the outer thigh.
Always keep your automatic injection device on you or within reach so that you can administer epinephrine swiftly in the event of an allergic reaction.
