Bee, wasp, hornet, scorpion, and fire ant stings can cause a life-threatening allergic reaction called anaphylaxis. Do you know how to respond in such a situation? While most insect bites can be treated at home and cause mild symptoms like itching, swelling, and a burning sensation that go away within a day or two, some bites can transmit bacteria, viruses, or parasites that cause diseases. Additionally, stings from bees, wasps, hornets, scorpions, and fire ants can trigger a serious and life-threatening allergic reaction known as anaphylaxis. Mayo Clinic offers guidance on how to approach the treatment of insect bites and stings.
When should you seek emergency assistance? Anaphylaxis is a severe allergic reaction that can be life-threatening, so it is crucial to act promptly. Call emergency services immediately if someone is bitten by a scorpion (especially a child) or if someone experiences a serious reaction indicative of anaphylaxis, even if there are only one or two symptoms:
- Difficulty breathing
- Swelling of lips, face, eyelids, or throat
- Dizziness, fainting, or loss of consciousness
- Weak and rapid pulse
- Skin rash
- Nausea, vomiting, or diarrhea
While waiting for medical assistance, take the following steps:
- Ask if the injured person carries an epinephrine auto-injector (e.g., EpiPen). Inquire if they need help with administering the medication. Usually, the auto-injector is pressed against the thigh and held in place for a few seconds.
- Loosen tight clothing and cover the person with a blanket.
- Do not offer anything to drink.
- If necessary, position the person to prevent choking on vomit.
What causes anaphylactic shock?
The most common cause of anaphylactic shock is allergic reactions to food. This sudden and drastic response is often triggered by allergenic foods such as peanuts, shellfish, soy, cow’s milk, and eggs, making them the leading culprits in most cases of anaphylaxis. However, anaphylaxis can also be caused by other allergens, including medications like antibiotics and anti-inflammatory drugs, as well as latex found in gloves and adhesive tapes. Venom injected into the body by bees or wasps can also induce a rapid allergic reaction, especially if the person is stung in a sensitive area like the neck. Prompt action is crucial in cases of anaphylactic shock.
How quickly do symptoms of anaphylactic shock appear?
Most symptoms develop within 5 to 30 minutes after contact with the allergen, such as a bee sting or food consumption. However, there are exceptions where symptoms may appear more than an hour later, although this is much less common.
How to treat mild reactions to insect bites or stings?
- Move to a safe area to avoid further bites or stings.
- Remove any stingers gently.
- Clean the affected area with soap and water.
- Apply a cold water-soaked cloth or ice pack to the bite or sting for 10 to 20 minutes. This helps reduce pain and swelling.
- If the injury is on your arm or leg, elevate it.
- Apply calamine lotion, baking soda paste, or 0.5% or 1% hydrocortisone cream to the affected area. Repeat several times a day until symptoms subside.
- Take an oral antihistamine to reduce itching.
- If needed, take over-the-counter pain medication.
- Seek medical help if swelling worsens, the area shows signs of infection, or you don’t feel well.
