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 posion ivy leaf.

The best way to avoid the itchy and occasional painful rash is to avoid poison ivy. This vine grows in a variety of environments, but enjoys brush near river banks and fields. If you must go in these areas, wear socks and long pants. Wash well with soap and water if contact is suspected. Also, be sure to launder clothing and to clean shoes as the poison ivy oil or sap on these items can continue to spread this irritating rash for weeks. If the oil gets on your pets, they can spread the rash in susceptible individuals so be sure to wash your cat and dog.

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. 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 presribe an oral cortisone medication to help clear the poison ivy.

Call your doctor if the rash involves more than 25% of the body, is accompanied by marked redness and swelling, or has a discharge that is cloudy like pus. Also call us if your child has a history of serious reactions to poison ivy .
