What Are the Common Symptoms of Severe Allergy?

Severe symptoms, especially swelling of the lips, tongue, and/or throat that blocks breathing, alone or combined with milder symptoms, may be signs of life-threatening anaphylaxis. This requires immediate treatment.

You should pay special attention to the following ones:

  • Trouble swallowing
  • Shortness of breath or wheezing
  • Turning blue
  • Drop in blood pressure (feeling faint, confused, weak, passing out)
  • Loss of consciousness
  • Chest pain
  • A weak or “thready” pulse
  • Sense of “impending doom”

Epinephrine is the first-line treatment for anaphylaxis, and your anaphylaxis plan should be individualized by your healthcare provider. Delays in administering epinephrine for severe or persistent symptoms can be very dangerous, especially when the delay is an hour or longer.
