What is the best treatment for a wasp sting?

Best Treatment for Wasp Stings

For typical wasp stings, the best treatment includes immediate removal of any stinger, washing with soap and water, applying ice or cold packs, and using over-the-counter medications for symptom relief. 1

Initial Assessment and Emergency Considerations

Recognize Severe Reactions

• Anaphylaxis requires immediate emergency response:

  • Difficulty breathing, tongue/throat swelling, lightheadedness, vomiting, widespread hives
  • If epinephrine autoinjector is available, it should be self-administered or assistance provided 1, 2
  • Activate emergency response system immediately 1
  • Anaphylaxis occurs in up to 3.5% of the population 3

• Eye stings require immediate professional medical evaluation 1

  • Can lead to permanent vision loss if not properly treated 1, 4

Treatment Algorithm for Typical Wasp Stings

Step 1: Immediate Care

• Unlike honeybees, wasps do not typically leave stingers behind, but if present:
  • Remove any stinger as soon as possible by plucking or scraping 1
  • Method of removal (plucking vs. scraping) doesn't matter - speed is key 1
  • Wasps can sting multiple times, unlike honeybees 1

Step 2: Clean the Area

• Wash the sting site with soap and water 1
• This helps reduce risk of secondary infection

Step 3: Pain and Swelling Management

• Apply ice or cold packs to the sting site 1
• Take over-the-counter pain medications:
  • Acetaminophen or nonsteroidal anti-inflammatory drugs (NSAIDs) 1

Step 4: Itching Control

• Use over-the-counter oral antihistamines 1
• Apply topical corticosteroids 1

Special Considerations

Large Local Reactions

• Extensive swelling around sting site that persists for several days 1
• Treatment:
  • Cold compresses to reduce pain and swelling 1
  • Oral antihistamines and analgesics 1
  • Oral corticosteroids may be used, though definitive proof of efficacy is lacking 1
  • Antibiotics are NOT indicated unless there is evidence of secondary infection 1

Multiple Stings

• Can cause systemic toxicity and multiorgan involvement 5
• Rarely can lead to rhabdomyolysis and acute renal failure 5
• Seek immediate medical attention if multiple stings occur

Pitfalls to Avoid

1. Misdiagnosing infection: Large local reactions with swelling and redness are typically due to mediator release, not infection 1
2. Delayed treatment of anaphylaxis: Epinephrine should be administered immediately for anaphylactic reactions 1, 2
3. Overlooking eye stings: These require specialized medical care 1, 4
4. Ignoring multiple stings: These can cause serious systemic effects beyond local reactions 5
5. Underestimating cardiac risk: Patients with pre-existing heart disease may rarely experience cardiac complications after wasp stings 6

Remember that while most wasp stings cause only mild local reactions requiring minimal treatment, recognizing the signs of more serious reactions is critical for preventing potentially life-threatening outcomes.
