When to Go to the ER for an Allergic Reaction

It is critical to understand when to seek emergency medical attention for allergic reactions. Anaphylaxis, the most severe reaction, with obvious symptoms such as trouble breathing and a weak pulse, needs emergency medical intervention. Angioedema (swelling of the face or throat) can restrict airways. Severe allergies can include cardiovascular symptoms, skin responses, gastrointestinal problems, and neurological symptoms.
