Treating Mild Bites or Stings

  • Move away from the area to avoid additional bites or stings.
  • To reduce pain and swelling, apply a cold pack or cloth filled with ice.
  • Apply a 1% or 0.5% hydrocortisone cream, calamine lotion, or a baking soda paste to the bite or sting several times a day.
  • Refrain from scratching, which can lead to infection. If you suspect that a bite or sting is infected, consider seeking medical treatment to prevent further complications.

Treating Severe Bites or Stings

Call 911 or get immediate medical help if:

  • If possible, have the person take an over-the-counter antihistamine, as directed on the bottle.
  • Have the person lie still on his back, with feet held above heart level.
  • Do not offer anything to drink.
  • Loosen tight clothing. Cover the person with a blanket.
  • If there is vomiting, turn the person to the side to prevent choking.
