Q: As a child, my face swelled up and I became short of breath after a bee sting. The doctor told my mother that I am allergic to bees. What can I do to prevent another reaction?

A: Approximately 10-15% of the general population is allergic to the venom of hymenopterous insects (bees, yellow jackets, wasps, and fire ants). Your previous reaction suggests you may be one such individual. There are a number of precautions you can take to avoid another allergic reaction. Obviously, avoidance is most effective. When outdoors, always wear shoes. This is probably the most important measure you can take to avoid contact with these insects. Hymenoptera are also attracted to perfumes and bright colors. A change in your scent or attire can make you less conspicuous to these insects. However, despite your best efforts, contact can sometimes be unavoidable. Because of this, it is important for you and your family to recognize the symptoms and signs of a generalized allergic reaction. In an allergic individual, the response to a sting can range from local swelling at the site of the bite to a more generalized reaction with symptoms including shortness of breath, lightheadedness, facial swelling, nausea, abdominal, and/or chest pain. An allergic person like you should carry an emergency self-treatment kit at all times. Your doctor can prescribe a kit for you. Such kits usually contain antihistamine tablets, a tourniquet, sterile swabs, and a syringe preloaded with a medication called epinephrine. It is critical to be prepared to use this kit when necessary. Although the kits always include instructions, you should familiarize yourself with how to use the kit and intermittently review the instructions. Remember that nobody ever plans to be stung! I suggest you consult your personal physician to discuss this important preventive health measure.
