Home Treatment If you are allergic to bee, wasp, or yellow jacket stings, it is important to carry a bee sting kit (which requires a prescription) and become familiar with how to use it if necessary. If stung, scrape a blunt object over the area to remove the stinger. Do not use tweezers, since these may squeeze the venom sac and increase the amount of venom released. Place ice (wrapped in a washcloth or other suitable covering) on the site of the sting for 10 minutes and then off for 10 minutes. Repeat this process. If patient has blood flow problems, place the ice on the skin for a shorter amount of time. (In such persons, ice may cause circulatory damage to the skin.) After a sting, call Poison Control or a hospital emergency room for guidance if the person has an allergic reaction (severe swelling or difficulty breathing). It may be necessary to go to the hospital if the reaction is severe. Before Calling Emergency Determine the following information: - Patient's age, weight, and condition
- Type of insect
- Time the sting occured
- Location of the sting
Poison Control, or a local emergency number The National Poison Control Center (1-800-222-1222) can be called from anywhere in the United States. This national hotline number will let you talk to experts in poisoning. They will give you further instructions. This is a free and confidential service. All local poison control centers in the United States use this national number. You should call if you have any questions about poisoning or poison prevention. It does NOT need to be an emergency. You can call for any reason, 24 hours a day, 7 days a week. See: Poison control center - emergency number What to expect at the emergency room If an emergency room visit is necessary, the health care provider will measure and monitor the patient's vital signs, including temperature, pulse, breathing rate, and blood pressure. Symptoms will be treated as appropriate. The patient may also receive breathing support, if needed. Expectations (prognosis) If an allergic reaction occurs, death may occur within 1 hour. The faster a patient gets medical help, the better the chance for recovery. Symptoms in those who do not have a sting allergy are likely to go away completely within a week.
