3 Common Symptoms of an Allergic Reaction

Symptoms of an allergic reaction can vary from person to person depending on preexisting conditions and the severity of the allergic reaction. When you take an ACLS (Advanced Cardiovascular Life Support) or BLS (Basic Life Support) recertification online course, or sign up to take your very first CPR in-person class, you will learn to look for the most common symptoms of an allergic reaction. Recognizing these symptoms is crucial for providing timely aid and preventing the condition from worsening. Here are three of the most common symptoms of an allergic reaction:

Common Symptoms of an Allergic Reaction

1. Swelling

Swelling can occur in various parts of the body and can manifest differently depending on the severity of the allergic reaction:

• Localized Swelling: This type of swelling happens in one specific area, such as where the skin came into contact with an allergen. Common examples include swelling around insect bites, rashes, or hives. The skin may appear red, raised, and feel warm to the touch. Localized swelling is often a sign of mild allergic reactions, which are generally not life-threatening but can be uncomfortable.

• Generalized Swelling: In severe cases, swelling can occur throughout the body. This includes swelling of the lips, tongue, throat, and even around the eyes, which can lead to vision impairment. Swelling of the throat or tongue is particularly dangerous as it can restrict airflow, leading to breathing difficulties and potentially life-threatening situations. This type of swelling, known as angioedema, requires immediate medical intervention.

Severe allergic reactions, also known as anaphylaxis, can progress rapidly. Knowing how to identify and respond to these symptoms can significantly improve recovery times for victims of severe allergens.

2. Low Blood Pressure

A sudden drop in blood pressure is another serious symptom of an allergic reaction, often indicating a severe reaction that requires immediate medical attention. This can result in several noticeable signs:

• Chest Tightness: The victim might experience tightness or pain in their chest, indicating that their cardiovascular system is being affected. This can be a sign of decreased blood flow to the heart and other vital organs.

• Extreme Fatigue: Due to the drop in blood pressure, the victim may feel extremely fatigued, weak, or lightheaded. This is because the brain and other vital organs are not receiving enough oxygenated blood.

• Nausea or Fainting: Lowered blood pressure can lead to dizziness, nausea, or fainting. These symptoms indicate that the body’s circulatory system is struggling to maintain adequate blood flow and pressure. In severe cases, the person may collapse and lose consciousness.

Recognizing these symptoms and responding promptly can help stabilize the individual and prevent further complications.

3. Runny Nose and Eyes

Runny nose and eyes are common, especially during allergic reactions to environmental triggers:

• Seasonal Allergies: Allergy sufferers often deal with runny nose and eyes during the spring and summer months when flowers, grass, and pollen are in bloom. These symptoms are caused by the body’s immune response to inhaled allergens. These symptoms are often associated with allergic rhinitis, commonly known as hay fever, which affects the nasal passages and eyes. Common environmental allergens include pollen, mold spores, and dust mites.

• Nasal Congestion: Some individuals may also experience a stuffy nose along with a runny nose, which can be uncomfortable and impact breathing. This congestion is due to inflammation and swelling of the nasal passages.

• Watery, Itchy Eyes: Allergens can cause the eyes to become watery, itchy, and red. These symptoms can be particularly bothersome and affect daily activities. Severe reactions can cause the eyes to swell shut.

While these symptoms are generally less severe than swelling or low blood pressure, they can still be distressing and require attention to prevent complications such as sinus infections or conjunctivitis.

Responding to Allergic Reactions

Knowing how to spot an allergic reaction is the first step in providing effective assistance. Here are some key actions to take:

In addition to immediate response measures, allergy shots can be an effective long-term treatment for managing allergic reactions. These shots work by gradually desensitizing the immune system to specific allergens, reducing symptoms over time.

Auto-Injectors

Individuals who are aware of their severe allergic reactions often carry an auto-injector, such as an EpiPen, prescribed by their doctor. Here are some important considerations:

• Awareness of Expiration Date: Auto-injectors have a limited shelf life and can lose effectiveness after expiration. Always check the expiration date and replace them as needed. An expired auto-injector may not deliver the proper dose of medication in an emergency.

• Proper Use: If you have an auto-injector, ensure you know how to use it correctly. If you are unsure, ask your doctor or nurse for a demonstration. Correct usage can be critical in a severe allergic reaction. Symptoms such as shortness of breath may indicate a severe allergic reaction, necessitating the use of an auto-injector. The auto-injector should be administered into the outer thigh muscle and held in place for a specified duration (usually about 10 seconds) to ensure the medication is fully delivered.

• Dosage Awareness: Be aware of the proper dosage for children versus adults. Auto-injectors come in different dosages, and using the correct one is vital for effectiveness.

CPR and First Aid Training

CPR and first aid certification programs, such as CPR level C and CPR pro certification courses, equip you with the skills to:

• Recognize Allergic Reactions: Training helps you develop the ability to notice the signs and symptoms of allergic reactions quickly. Training helps you understand how the immune system reacts to allergens, leading to various symptoms. Early recognition is key to preventing the condition from worsening.

• Provide Immediate Aid: Learning how to administer CPR and first aid effectively can save lives. This includes knowing how to use an auto-injector and perform life-saving techniques if the victim experiences severe symptoms like anaphylaxis. CPR may be necessary if the person stops breathing or their heart stops beating.

• Stay Calm and Reassure the Victim: Staying calm and reassuring the victim can help reduce their anxiety and panic, which can worsen symptoms. Provide clear instructions and support to help them remain as comfortable as possible.

Step-by-Step Response to Severe Allergic Reactions

1. Assess the Situation: Quickly determine if the person is having a severe allergic reaction. Look for symptoms such as difficulty breathing, swelling, and low blood pressure. Common triggers of severe allergic reactions include food allergies, which can cause symptoms such as difficulty breathing and swelling.

2. Administer the Auto-Injector: If the person has an auto-injector, help them use it immediately. Ensure the injection is given in the outer thigh and hold it in place for the recommended time.

3. Call Emergency Services: Dial 911 or your local emergency number immediately after administering the auto-injector. Inform them that the person is experiencing a severe allergic reaction and needs immediate medical attention.

4. Monitor the Victim: Keep a close watch on the person’s condition. If they are not breathing or their heart stops, begin CPR if you are trained to do so. Follow the guidelines for chest compressions and rescue breaths.

5. Provide Additional Care: If the person becomes unconscious but is still breathing, place them in the recovery position to keep their airway open and prevent choking if they vomit.

6. Prepare for Secondary Reaction: Sometimes, symptoms can return even after initial treatment. Be prepared to administer a second dose of the auto-injector if the person’s condition does not improve or worsens after 5-15 minutes.
