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) BLS (basic life support) recertification online course or if you sign up to take your very first CPR in person classes, you will learn to look for the most common symptoms of an allergic reaction so that you can be sure to render aid to someone in need before their condition worsens. Three of the most common symptoms of an allergic reaction are:

  1. Swelling. Swelling can happen in one location, like a part of the skin where the exposed area came into contact with an allergen. Swelling can also happen all over the body in severe cases and can sometimes result in swollen lips or throat which may restrict airflow to the body.  Severe allergic reactions can happen quickly. Knowing what to do can help improve recovery times for victims of severe allergens.  
  2. Low blood pressure. A sudden drop in blood pressure could be an indication of an allergic reaction. The victim might feel tightness in their chest or extreme fatigue from the drop in blood pressure. Nausea or fainting may also occur due to the lowered blood pressure.  
  3. Runny nose and eyes. Runny nose and eyes are common symptoms of an allergic reaction.  Some individuals have a stuffy nose in addition to a runny nose. Allergy sufferers deal with runny nose and eyes during the spring and summer months the most when natural environmental allergens are in bloom such as flowers, grass, and pollen.  

Knowing how to spot an allergic reaction can help you take action swiftly if needed. Individuals who know they have severe allergic reactions can carry an auto-injector with them from a written prescription from their doctor. If you do decide to carry an auto-injector, be mindful of the expiration date.  They do not have a long shelf life and decrease in effectiveness after expiration. If you have never used one before, ask your doctor or nurse to demonstrate how to use an auto-injector correctly so that you can benefit from that resource and tool. CPR level C online course programs and CPR pro certification courses all help you train your eyes to notice allergic reactions.  Be a lifesaver with CPR and first aid certification programs!
