What is the treatment for wasp stings?

Benadryl, (diphenhydramine)ice, epi: For local reactions Benadryl and ice will help. Tylenol (acetaminophen) would be reasonable for pain.

For patients with systemic reactions venom immunotherapy (desensitization) is strongly recommended.

Varies: A small bump at the site will go away in several hours, and doesn't need to be treated. If it gets larger and warmer and painful over a couple of days, it might be infected - see your physician. If you have symptoms away from the site such as hives, wheezing or dizziness - see an allergist.
