Prevention of Asian Giant Hornet Stings


Hello Dr.
Liao,
Due to the need for outdoor activities, in addition to the following precautions: 1.
Use insect repellent containing DEET; 2.
Avoid dark-colored, woolen, or rough-textured clothing materials, and it is best to wear smooth, light-colored long-sleeved shirts and long pants with hats (tuck pants into boots and wear long sleeves and pants); 3.
Do not spray or carry perfumes, cosmetics, or products with strong odors; 4.
When encountering bees, remain still and do not swat at them, allowing them to fly away on their own.
According to the Ministry of Labor's 2015 manual on preventing attacks from hornets during outdoor work, for minor stings with localized reactions, one can gently remove the stinger using a fingernail, blade, or credit card, then clean the wound, apply ice, and use a topical antibiotic with a steroid ointment.
Oral antihistamines may also be added.
I would like to ask: 1.
Can saline solution be used to clean the wound? 2.
Are the antibiotic with steroid ointment and oral antihistamines prescription medications? Do they need to be obtained from a hospital outpatient clinic? If not, when purchasing at a pharmacy, are there any specific ingredients or other matters that need to be communicated to the pharmacist? 3.
For those with more severe allergic reactions, are there related medications (such as EpiPen) that can be obtained from family medicine or travel clinics?
Thank you in advance for your response!

More Info


When it comes to preventing hornet stings during outdoor activities, it's essential to take a proactive approach to minimize the risk of encounters with these insects. Here are some key strategies and answers to your specific questions regarding first aid and medication.


Preventive Measures Against Hornet Stings
1. Use Insect Repellent: As you mentioned, using repellents containing DEET can be effective. Apply it to exposed skin and clothing, but avoid contact with the eyes and mouth.

2. Wear Appropriate Clothing: Opt for light-colored, smooth fabrics, as dark colors and rough textures can attract hornets. Long sleeves and pants are advisable, and tucking pants into boots can help prevent stings on the legs.

3. Avoid Strong Scents: Stay away from perfumes, scented lotions, and other fragrant products that might attract hornets.

4. Stay Calm Around Hornets: If you encounter a hornet, remain still and avoid swatting at it. Most hornets will fly away if left undisturbed.


First Aid for Hornet Stings
In the event of a sting, here are the recommended first aid steps:
1. Remove the Stinger: If the sting involves a stinger left in the skin, use a fingernail, credit card, or a knife edge to scrape it out gently. Avoid using tweezers, as squeezing can release more venom.

2. Clean the Wound: You can use saline solution or clean water to rinse the area. Saltwater is not typically recommended for wound cleaning, as it can irritate the skin. Instead, use plain water or a saline solution to avoid further complications.

3. Apply Cold Compress: Ice wrapped in a cloth can help reduce swelling and pain.

4. Topical Treatments: Over-the-counter creams containing hydrocortisone or antihistamines can help alleviate itching and inflammation.
5. Oral Antihistamines: Medications like diphenhydramine (Benadryl) can help manage allergic reactions and are available over-the-counter.


Medication Queries
1. Antibiotic and Steroid Ointments: These are often prescription medications. While some topical antibiotics may be available over-the-counter, stronger formulations typically require a prescription. It's advisable to consult with a healthcare provider for appropriate recommendations.

2. EpiPen for Severe Allergic Reactions: Individuals with a history of severe allergic reactions to stings should carry an EpiPen (epinephrine auto-injector). These can be obtained through a healthcare provider, and it’s crucial to have one on hand if you know you are at risk for anaphylaxis.

3. Consulting a Pharmacist: When purchasing over-the-counter medications, it’s beneficial to inform the pharmacist of your specific needs. They can guide you on the appropriate products and dosages based on your health history and any other medications you may be taking.


Conclusion
Being prepared and knowledgeable about hornet sting prevention and first aid can significantly enhance your safety during outdoor activities. Always prioritize wearing appropriate clothing, using insect repellent, and remaining calm if you encounter hornets. In case of a sting, follow the first aid steps outlined above, and consult healthcare professionals for any medications you may need, especially if you have a history of severe allergic reactions.
