These kits require a prescription. They contain a medicine called epinephrine, which you should take right away if you get a wasp sting.To treat the wasp sting:Try to remove the stinger from the skin (if it is still present). To do this, carefully scrape the back of a knife or other thin, blunt, straight-edged object (like a credit card) across the stinger if the person can keep still and it is safe to do so. Or, you can pull out the stinger with tweezers or your fingers. If you do this, do not pinch the venom sac at the end of the stinger. If this sac is broken, more venom will be released. Clean the area thoroughly with soap and water. Place ice (wrapped in a clean cloth) on the site of the sting for 10 minutes and then off for 10 minutes. Repeat this process. If the person has problems with blood circulation, decrease the time that the ice is on the area to prevent possible skin damage. Keep the affected area still, if possible, to prevent the venom from spreading. Loosen clothing and remove rings and other tight jewelry. Give the person diphenhydramine (Benadryl and other brands) by mouth if they can swallow. This antihistamine drug may be used alone for mild symptoms.

Severe allergic reactions may require a tube down the throat and breathing machine (ventilator). Chest x-ray. ECG (electrocardiogram, or heart tracing). Intravenous fluids (IV, through a vein). Medicines to treat symptoms. Outlook (Prognosis) How well a person does depends on how allergic they are to the insect sting and how quickly they receive treatment. The faster they get medical help, the better the chance for recovery. The chances of future total body reactions increase when local reactions become increasingly severe.People who are not allergic to wasps, bees, hornets or yellow jackets usually get better within 1 week.DO NOT put your hands or feet in nests or hives or other preferred hiding places.
