Stinging Insect Allergy 

Many people are stung reach year by insects such as bees, wasps, hornets, and yellow jackets.  Most people only experience swelling, redness, and pain near the place they were stung.  These symptoms may last several hours or more and are not considered an allergic reaction.   

However, some people will develop an actual allergy to the stinging insect.  Like many other types of allergic reactions, these individual’s will develop an allergy antibody (IgE) to a protein found in the insect venom.   

Symptoms of an insect allergy are similar to those found with food allergies and include one or more of the following- hives (red, itchy, and swollen areas of the skin); swelling of the eyes, lips, tongue or throat; abdominal pain or diarrhea; and wheezing or shortness-of-breath.  Life-threatening reactions may also develop and include severe wheezing, swelling of the throat and tongue, a large drop in blood pressure, and feelings of warmth or flushing.  Most insect allergies occur immediately after the insect sting occurs.  However, symptoms may be delayed for up to 1-2 days after the insect bite occurs in some people.   

Anyone who has experienced a possible insect allergy should be evaluated by an allergist/immunologist, who will take a complete history, perform appropriate testing, and recommend a treatment plan designed specifically for you or your family member.  Skin testing is the most accurate way to diagnose insect allergies.  Unlike with food allergies, allergy shots (immunotherapy) are a highly effective and potentially life-saving treatment option for those who have more severe insect allergies.  It is also important to carry injectable epinephrine and to call 911 immediately if you experience symptoms that are suggestive of an anaphylactic reaction to an insect.
