Dealing with Allergic Reactions: A First Aid Guide


An allergic reaction is an immune system response triggered by exposure to something your body considers harmful. It often results in swelling, a runny nose, or an itchy rash, but it can also cause hives, difficulty breathing, or swallowing—even death. The reaction could be mild and subside within minutes or trigger a life-threatening emergency that requires immediate medical attention.

Identifying an Allergic Reaction

An allergic reaction is a response by your body to an allergen (a substance that causes an allergic reaction). Anaphylaxis is a severe, whole-body reaction to an allergen. It can cause death if not treated quickly.

Symptoms of an allergic reaction include:

  • Hives or welts on the skin
  • Swelling around the lips, eyes, and throat
  • Wheezing or trouble breathing

If you are having an allergic reaction:

  • Seek medical attention immediately! Do not wait until it gets worse; this could lead to serious complications such as anaphylaxis or death! 2) If possible before going out into public places like restaurants where there may be potential allergens present try wearing protective clothing like long sleeves shirts with pants tucked inside them so no skin is exposed (this will also help prevent sunburns). 3) Try keeping antihistamines handy just in case things start getting worse than expected."

Treating an Allergic Reaction

  • Call 911 if you have an allergic reaction. Anaphylaxis is a medical emergency and requires immediate treatment.
  • Stay calm and stay with the person having an allergic reaction until help arrives.
  • Apply ice to the area of the reaction (if safe to do so). This will help reduce swelling and pain, as well as limit further damage to tissue by constricting blood vessels in that area.
  • Take an antihistamine (such as Benadryl) according to package directions if possible before going to your doctor or hospital emergency room for additional treatment options such as epinephrine auto-injectors.
  • Ask a paramedic, police officer, or firefighter trained in administering epinephrine auto-injectors if he/she has one available; this medication must be given immediately following contact with allergen trigger(s), regardless of whether symptoms are present.

Identifying the Allergen

  • Know what your allergies are. If you have asthma, hay fever, or eczema, it's important to know which allergens trigger those reactions.
  • Be aware of when to seek medical attention. If you've had a reaction before and know what the symptoms are, then go ahead and see a doctor if those symptoms reappear again later on in life (and especially if they get worse).
  • Learn how to recognize the signs of an allergic reaction so that you can take action immediately if needed--it could save someone's life!
  • Avoid known allergens at all costs! If someone is allergic to bee stings but wants to go camping with friends who love nature walk through fields full of bees...well...maybe reconsider this trip? Or maybe just stay inside during peak bee season instead?
  • Have an emergency plan in place for dealing with allergic reactions: knowing what steps will need to be taken beforehand will help everyone involved feel more confident about handling any situation that arises unexpectedly.

Preventing Allergic Reactions

There are several ways you can prevent an allergic reaction. The most obvious is to avoid the allergen entirely. If you're allergic to cats, don't pet them--or at least wear gloves when you do so. If peanuts are a problem for you, don't eat them (and make sure that none of your friends or family members brings them into your home).

If avoiding an allergen isn't possible, talk with your doctor about medications that might help reduce symptoms if they occur. For example:

  • Antihistamines such as Benadryl (diphenhydramine) can help with both itching and sneezing. They may also be useful if someone around you has been exposed to something they shouldn't have been and starts experiencing symptoms; take some antacids beforehand if possible so they'll be ready in case things get bad quickly!
  • Epinephrine autoinjectors contain epinephrine which works quickly at relieving swelling around the mouth/throat area caused by food allergies (like peanuts), pollen allergies (like oak trees), insect stings/bites etcetera... But remember not everyone needs one because there are many different types out there depending on what exactly yours entails."

Practice and learn to recognize the symptoms of an allergic reaction and have a plan in place.

Allergic reactions can be mild or severe, life-threatening, and even fatal. The most common allergens are food, medication, and insect bites/stings. They can also be caused by touching plants or animals that are known to cause an allergic reaction (like poison ivy).

The earlier you recognize the symptoms of an allergic reaction the better. If you have been diagnosed with a food allergy or any other type of allergy, learn about your condition so that you know what to look for when it comes time for treatment - remember: "An ounce of prevention is worth a pound of cure!" The most common food allergens are milk, eggs fish shellfish peanuts tree nuts soy wheat


I hope this article has been helpful in understanding how to deal with allergic reactions. If you or someone you know has an allergy, it's important to be aware of the symptoms and act quickly if they appear. If possible, keep emergency treatment on hand in case of an emergency situation!
