Are You Allergic Insect Stings?

Insect stings can cause mild to severe allergic reactions in people. Some people may develop an allergy to the venom of certain insects, such as bees, wasps, yellow jackets, and hornets. If you have an insect sting allergy, your body's immune system overreacts to the venom, causing various symptoms.

Mild allergic reactions to insect stings may include:

- Redness, swelling, itching, and pain at the sting site

- Hives (raised, itchy bumps on the skin)

- Nausea and vomiting

- Diarrhea

- Mild swelling of the face, lips, tongue, and throat

Severe allergic reactions (anaphylaxis) to insect stings are rare but can be life-threatening. Symptoms of anaphylaxis may include:

- Difficulty breathing

- Wheezing

- Swelling of the throat, making it hard to swallow

- Rapid pulse

- Dizziness or fainting

- Nausea and vomiting

- Loss of consciousness

If you experience severe allergic symptoms after an insect sting, seek emergency medical attention immediately. Anaphylaxis can be treated with epinephrine (adrenaline), a hormone that can help reverse the symptoms.

Preventing insect stings

- Avoid areas where stinging insects are common, such as flowering plants, fruit trees, and garbage cans.

- Wear protective clothing, such as long sleeves and pants, when outdoors in areas where stinging insects are present.

- Use insect repellent that contains DEET (N, N-diethyl-m-toluamide).

- Keep food and drinks covered when outdoors to avoid attracting insects.

- Be aware of the location of insect nests and avoid them.

If you are allergic to insect stings, you should carry an epinephrine auto-injector (EpiPen) with you at all times in case of an emergency. Always follow the instructions provided by your doctor for using your EpiPen.
