Apitoxin poisoning; Apis venenum purum poisoning; Apis virus poisoning
Bee poisoning is caused by a sting from a bee, wasp, or yellow jacket.
This article is for information only. DO NOT use it to treat or manage an actual poisoning from a sting. If you or someone you are with is stung, call your local emergency number (such as 911), or your local poison center can be reached directly by calling the national toll-free Poison Help hotline (1-800-222-1222) from anywhere in the United States.
Bee, wasp, hornet, and yellow jacket stings contain a substance called venom. Africanized bee colonies are very sensitive to being disturbed. When they are disturbed, they respond faster and in greater numbers than other types of bees. They are also much more likely to sting than European bees.
Bee, wasp, hornet, and yellow jacket venom can cause an allergic reaction in some people.
A reaction to a sting may include these symptoms in different parts of the body:
EYES, EARS, NOSE, AND THROAT
- Swelling in the throat, lips, and mouth *
- Abdominal cramping
- Nausea and vomiting
HEART AND BLOOD VESSELS
- Severe decrease in blood pressure
- Collapse *
- Hives *
- Swelling and pain at site of the sting
* These symptoms are due to an allergic reaction, and not venom.
If you have an allergy to bee, wasp, or yellow jacket stings, always carry a bee sting kit and know how to use it. These kits require a prescription. They contain a medicine called epinephrine, which you should take right away if you get a bee sting.
Call poison control or a hospital emergency room if the person who is stung has an allergy to the insect or was stung inside the mouth or throat. People with severe reactions may need to go to the hospital.
To treat the bee 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.
Before Calling Emergency
Have this information ready:
- Person's age, weight, and condition
- Type of insect, if possible
- Time of the sting
- Location of the sting
Your local poison center can be reached directly by calling the national toll-free Poison Help hotline (1-800-222-1222) from anywhere in the United States. 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.
What to Expect at the Emergency Room
The health care provider will measure and monitor the person's vital signs, including temperature, pulse, breathing rate, and blood pressure. Symptoms will be treated. The person may receive:
- Blood and urine tests
- Breathing support, including oxygen; (tube through the mouth into the throat, and breathing machine in serious cases)
- Chest x-ray
- ECG (electrocardiogram, or heart tracing)
- Fluids through a vein (by IV)
- Medicine to treat symptoms
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 more and more severe.
People who are not allergic to bees or wasps usually get better within 1 week.
DO NOT stick your hands or feet in nests or hives or other preferred hiding places. Avoid wearing bright colored clothing and perfumes or other fragrances if you will be in an area where bees are known to gather.
