Now that the weather in Tysons Corner, VA, Gainesville, VA, and Falls Church, VA and the rest of the Washington, DC metropolitan area has warmed up, as it is now Summer, the risk of an insect sting has increased. The most common stinging insects in the Washington, DC metro area are honey bees, yellow jackets, white-faced hornets, yellow-faced hornets, and wasps. They all introduce their venom into their subjects when they sting their prey. In some cases, people have toxic (i.e., non-allergic) reactions to the insect stings, particularly if stung by several insects at the same time. The body, in this case, generally reacts to the venom as if it was a poison. This can occur because the victim is exposed to an over-abundance of venom at one time. A toxic reaction can cause symptoms similar to those of an allergic reaction, but also may include symptoms such as nausea, fever, and seizures. This can be life-threatening and depends on the amount of venom injected into the individual. On the other hand, about 3% of individuals experience true allergic reactions, which is usually not dependent on the amount of venom, but to the allergic response to the venom by the individual. These allergic reactions can also be life-threatening.
When stung, most individuals have no reaction or a small local reaction. People with this type of response are at no increased risk for a systemic (anaphylactic) reaction than that of the general population. Other people will develop a large local reaction, where the area that was stung gets red and very swollen. This large local reaction can reach the size of a baseball in some cases. Still, however, there is no increased risk in these individuals of a systemic or anaphylactic reaction from the insect sting. On the other hand, a small percentage of individuals will develop a systemic reaction to an insect sting which may include some or all of the following: generalized itching (i.e., pruritus), hives (i.e., urticaria), swelling (i.e., angioedema) of another area of the body where the sting did not take place, abdominal cramping and pain, wheezing, shortness of breath, chest tightness, coughing, feeling faint, and drop in blood pressure.
If a person has had a large local reaction or a systemic reaction to an insect sting, they should definitely seek a consultation with a board certified allergist like the allergy specialists of Black & Kletz Allergy. The allergists that Tysons Corner, VA, Falls Church, VA, Gainesville, VA, and Washington, DC residents have trusted for years have had over 50 years’ experience diagnosing and treating insect sting allergies. A comprehensive history and physical examination is taken and then a decision is made whether to test that individual for allergies to honey bees, yellow jackets, white-faced hornets, yellow-faced hornets, and wasps. Allergy testing can be done via blood or by skin tests. The allergist will then decide the preferred method of testing for each specific individual, depending on the history of the reaction that is ascertained at the visit.
Measures in order to help prevent insect stings are discussed with patients, as well as what things should be done, if a future sting occurs. For example, if stung by a honey bee, a stinger is left in the skin of the victim. One should never pull out the stinger, as this actually increases the amount of venom that is introduced into the individual by causing contractions of the venom sac which is hidden under the skin of the person. Instead, one should scrape off the stinger with a finger nail, credit card, etc. in order to prevent the introduction of more venom into the body of the individual.
If a patient has a positive allergy test to any of the stinging insect venoms, it is imperative that he/she go on a course of venom allergy immunotherapy (i.e., allergy shots, allergy injections, allergy desensitization) as it is extremely successful in preventing further anaphylactic reactions from insect stings. The procedure entails giving progressively larger doses and volumes of insect venom to the individual weekly over a period of 10 weeks, then every 2 weeks for 1 dose, then every 3 weeks for 1 dose, then a maintenance dose every 4 weeks for 1 year, and then the maintenance dose can be decreased to every 6 weeks for several years. The maintenance dose is roughly equivalent to the amount of venom in an actual sting. Therefore, if someone gets stung while they are on a maintenance dose of venom immunotherapy, they are essentially getting the same dose of venom as they normally get every 6 weeks. For this reason, they usually do not have a systemic reaction to the stinging insect, because they are protected due to the allergy shots.
All patients with allergic reactions to stinging insects are prescribed a self-injectable epinephrine device (e.g., EpiPen, Auvi-Q, Adrenaclick). At Black & Kletz Allergy, individuals are taught the correct method on how to use, when to use, and what to do, after using these devices. We have training devices that we use to show patients the proper way to use them. As a general rule, if someone is stung by a stinging insect and experiences any systemic sign or symptom, they should use the self-injectable epinephrine device and go immediately to the closest emergency room.
