First Aid: How to Treat Allergic Reaction


Your immune system creates antibodies to fight against foreign substances so you won’t get sick. Sometimes your system will identify a harmful substance even though it is not. When this happens, it is called an allergic reaction. With some dangerous reaction, knowing some first aid tips can help you to save your life and people around you.

These substances or allergens can be anything from food, medication, or environments.

When will you need first aid?

You have to give the patients first aid if they have any severe reactions in the past or have any of these symptoms:

  • Difficulty breathing or wheezing,
  • Hoarseness or trouble speaking,
  • Tightness in the throat or a feeling that the airways are closing,
  • Swollen lips, tongue, or throat,
  • Fast heartbeat or pulse,
  • Nausea, abdominal pain, or vomiting,
  • Loss of consciousness,
  • Anxiety or dizziness,
  • Other symptoms of a severe allergic reaction (anaphylaxis).

If you have severe allergies, you ought  to keep two  epinephrine injection kits with you at all times and readily available.

Some information you have to concern about anaphylaxis

The most serious allergic reactions may cause anaphylaxis.  This reaction can happen a few minutes after exposure and if left untreated, can lead to loss of consciousness, cardiac arrest  and respiratory distress.

Its signs include:

  • Skin reactions such as hives, itching, or pale skin,
  • Lightheadedness, dizziness, or fainting,
  • Facial swelling,
  • Wheezing or trouble with breathing,
  • Nausea,
  • Weak and fast pulse.

What should you do if you are with someone who is experiencing anaphylaxis?

  • Call emergency phone number immediately.
  • Inject immediately at first sign of anaphylaxis. The injection can’t  harm them if it is a false alarm but could save their life. If the person has an anaphylaxis action plan from a doctor about injecting epinephrine and other emergency measures, follow it.
  • Try to keep the person calm.
  • Help the patient lie on their back.
  • Raise their feet about 12 inches and cover them with a blanket.
  • If they are vomiting or bleeding, you should turn them on their side.
  • Make sure their clothing is loose so they can breathe.

The sooner the person gets their epinephrine, the better. You should avoid giving oral medications, anything to drink, or lifting their head, especially if they’re having trouble breathing.

CPR for anaphylaxis

If the person isn’t breathing, coughing, or moving, you may need to perform CPR. This can be done even without formal CPR training. CPR involves doing chest presses, about 100 per minute until people who can help arrive. You also should participate in a CPR training class if your family members have any symptoms of allergic reactions.

The more control you keep your contact with allergens, the less likely you will have an allergic reaction. Make sure your coworkers and friends know about your allergies and where you keep your epinephrine auto-injector. You should also teach your friends how to treat an allergic reaction can help save a life.
