Poison Ivy

"My girlfriend and I went on a picnic. I don't know how she did it, but she got poison oak on the brain. When it itched, the only way she could scratch it was to think about sandpaper." --Stephen Wright

Every year about this time I break out with poison ivy on my arms. It comes from our cats who wander about outdoors by day and then sleep with us at night. Each year we spray our backyard but the poison ivy keeps coming back. In our family I’m the most sensitive. For me the rash spreads into large patches covered with tiny blisters. My wife is more resistant but when she does catch it, she gets a few large blisters at the points of contact.

A poison ivy rash is the result of the plant oil reacting to surface skin. The skin becomes irritated, blisters up, and creates an intense itching and burning sensation. The top layers of skin will die off and peel away, and it takes time for healthy skin to replace the damaged layers of skin. The rash may remain for up to three weeks without treatment. Blister fluid from scratching doesn't spread the rash, but germs from your fingernails may cause a secondary infection.

There are many recommended treatments but few seem to work on me. Beware of Internet cures! For example, some sites recommend bleach but you should never use this product on your skin under any circumstances.

The ideal treatment for poison ivy is within the first 15 minutes of contact – before the skin is damaged. Wash with water, rubbing alcohol or some OTC medications. Do not use soap at first – soap will spread the oil.

Sadly most of us miss the 15-minute window and have to deal with the rash. Typical treatments for poison ivy rash are directed at controlling the itch, and can include non-steroidal creams, topical (skin) steroids, oral antihistamines (Benadryl), oral steroids (prednisone), or a steroid shot.

The traditional low-cost anti-itch medication is Calamine lotion. Wet dressings, compresses, or soaks with Domeboro Astringent solution (mixed with water) is said to be especially soothing for itchy rashes.

Other examples from About.com include:

•Atarax (hydroxyzine, a prescription oral antihistamine)
•Aveeno Anti-Itch Cream with Natural Colloidal Oatmeal
•Aveeno 1% Hydrocortizone Anti-Itch Cream (OTC topical steroid)
•Band-Aid Anti-Itch Gel
•Caladryl Clear Topical Analgesic Skin Lotion
•Cortizone 10 (OTC topical steroid)
•Cutivate cream 0.05% (prescription topical steroid)
•Domeboro Astringent Solution Powder Packets
•Gold Bond Maximum Strength Medicated Anti-Itch Cream
•Itch-X Anti-Itch Gel with Soothing Aloe Vera
•Locoid cream 0.1% (prescription topical steroid)
•Triamcinolone acetonide 0.1% (prescription topical steroid)

Newer medications that are supposed to target poison ivy symptoms include:

•Burts's Bees Poison Ivy Soap
•Cortaid Poison Ivy Care Treatment Kit
•Ivarest Medicated Cream
•IvyStat
•Tecnu Extreme Poison Ivy Scrub
•Zanfel Wash For Poison Ivy, Oak & Sumac

Bottom Line

Test your knowledge with the Poison Ivy quiz. My score was 16/20.

When killing poison ivy, be aware that the Urushiol oil can penetrate latex gloves. Use rubber gloves instead. Remember that the oil can remain on gloves, weeders, mowers, clippers, and other tools for a year (longer in dry climates). Wash equipment and shoes with soap and water while wearing protective gloves. Then wash the gloves and toss your clothes in a washing machine.

Never burn any poisonous plant. You might inhale the oils and irritate your lungs and throat.

See a doctor "if the rash is on the face, genitals, or covers more than 30 percent of the body.”

Try Common Plantain (Plantago Major). It's amazing the things we have learned to forget.
