Understanding Allergies -- Symptoms

What Are the Symptoms of Allergies?

The symptoms of allergies include:

Call Your Doctor About Allergies if:

Get immediate emergency medical treatment if:

  • Swallowing or breathing becomes difficult or painful; you may be experiencing an asthma episode, anaphylaxis, or a heart attack.
  • You suddenly develop skin welts accompanied by intense flushing and itching; your heart may also be beating rapidly. These symptoms may indicate the onset of anaphylactic shock, an extremely serious allergic reaction.

If you have severe allergies, you should keep two epinephrine injection kits with you at all times and readily available. If you experience any sign of anaphylaxis, do not hesitate to use the epinephrine auto-injector, even if those symptoms do not appear to be allergy related. Using the auto-injector as a precaution will not harm you.
