POISON IVY
What is poison ivy?
Poison ivy is a
perennial pest which is easily
identified by its ropey vine, fuzzy roots, and triad of leaves. The
leaves vary in color by season beginning as a light yellow-green in the
spring (or occasionally reddish green) to a deep shiny green in the
summer, to an orange-red in the fall. No matter the color or season,
poison ivy can cause a blistering rash when it comes in contact with
the skin of people who are sensitive or allergic to the oily chemical
on the poison ivy leaf.
What does the poison ivy
rash look like?
The rash is characterized by weeping blisters which occur in
a
linear streak or patch. It may be accompanied by mild redness and
swelling. Extreme itchiness is common. The rash may occur 1-2 days
after
exposure to the plant and typically lasts 2 weeks.
How do I protect my child against poison ivy?
• Avoid areas where poison ivy is likely to grow, such as river banks and fields.
• If you must go into areas where poison ivy may be located, wear socks and long pants.
• Wash well with soap and water if contact is suspected.
•
Launder clothing and clean shoes as the poison ivy oil or sap on
these items can continue to spread this irritating rash for weeks.
•
Wash your pets if they are have been exposed to poison ivy, as
the oil can stay on their fur and can spread the rash to susceptible
individuals.
What is the treatment for poison ivy?
•
Oral diphenydramine (Benadryl) and topical calamine lotion or
oatmeal baths will help the itching, but will not reduce the time
course of the rash.
• 1% hydrocortisone cream will help to make the rash go away.
•
Occasionally, if the rash is severe or involves the area around
the eyes, we will prescribe an oral cortisone medication to help clear
the poison ivy.
When should I call my doctor?
• If the rash involves the face, or more than 25% of the body.
• If the rash is accompanied by marked redness and swelling.
• If the rash has a discharge that is cloudy like pus.
• If your child has a history of serious reactions to poison ivy .
