Which treatment is appropriate for poison ivy exposure?

• A. Stir plants into tea for relief
• B. Wash skin, calamine, antihistamine
• C. Cover with heavy ointment without washing
• D. Scrub skin hard with soap and water until raw

Answer: (B)

Exposure to poison ivy works through a resin called urushiol that sticks to skin and objects. The best immediate approach is to wash the exposed area with soap and plenty of running water as soon as possible to remove as much resin as you can; this often reduces how badly you react. After washing, soothing the itch with calamine lotion and, if needed, an oral antihistamine can help manage symptoms. Avoid covering irritated skin with a heavy ointment without washing, since that can trap the resin. Also avoid aggressive scrubbing, which can irritate skin and worsen discomfort. On a paddling trip, have soap and water handy to rinse quickly, and seek medical care if the reaction is widespread, involves the face or eyes, or breathing becomes affected.
