What are some signs that someone is having a severe allergic reaction?

Answer 1

There are many signs to an allergic reaction (I have had 5 myself) and they sometimes may not stand out. If there is itching of the lips, almost always the next step will be the closing of the throat. Insert Benadrill or other allergy meds. If allergic reaction seems to get worse, call a doctor or go to the emergency room IMMEDIATELY!!!!!!!!!

Answer 2

An allergy reaction is a response from the innate immune response system. It can manifest in several forms. A reaction that is most common on the skin is redness. This is due to the flow of blood near the skins surface at the site of the reaction, such as a bee sting. A second symptom occurring from blood flow is heat. The reaction site will become warm to the touch. A third symptom is swelling at the reaction site. This occurs due to the increase of blood flow, particularly the blood plasma, the straw-colored part of blood that contains the immune components that destroy foreign material. Itching may also be a symptom at the reaction site from the nerves in the skin. Small red bumps may also occur at the site. In other cases, allergic reactions may manifest as nasal drip, nasal inflammation, and in more severe reactions anaphylactic shock in which the respiratory system becomes paralyzed/swollen in which labored breathing, dizziness, unconsciousness, or death may occur.

Answer 3

There are usually signs of inflammation (rash, swelling, hives, etc.). Sometimes, in more severe cases, this extends to difficulty breathing. Difficulty breathing can result in cyanosis (bluish tinge to skin, especially that of the face and lips), which is indicative of hypoxia (low blood oxygen concentration).

A severe allergic reaction is often treated with an injection of epinephrine (adrenaline), such as an EpiPen.
