how to treat a wasp sting

To treat a wasp sting, first wash the affected area with warm soap and water to clean out bacteria and venom. Then apply a cold pack wrapped in a cloth to the site for 10 to 60 minutes in intervals to reduce swelling and pain. Taking an anti-inflammatory medication like ibuprofen can also help reduce pain and swelling. For itchiness, apply an antihistamine, corticosteroid, or calamine cream. Avoid scratching the sting. If there is a severe allergic reaction, such as difficulty breathing or swelling in the mouth or throat, seek emergency medical help immediately. For those with a history of allergies to stings, use an epinephrine auto-injector (EpiPen) if stung and call 911.
