If your family enjoys time in the woods while hiking or camping, you may have been affected by the rash caused by poison ivy, poison oak or poison sumac.
This itchy allergic reaction is caused by exposure to oils found on plants in the Genus Toxicodendron. The allergenic compound found in these plans is called urushiol. Interestingly, the same substance is also found in ginko fruit and mango peels. This colorless oil is found in all parts of the plant. When it is exposed to the air, it may turn black, causing spots to appear on the leaves. The rash associated with exposure to urushiol develops anywhere between 4 hours and 4 days after exposure. The rash is intensely itchy, red, somewhat swollen and generally has fluid-filled blisters that present as lines or streaks.
The rash can appear on different parts of the body at different times. Remember that poison ivy is not contagious; you cannot pass it from one person to another. However, the oils from the plant can be carried on clothing, on garden tools, under fingernails or even on pets. Therefore, other family members can develop dermatitis, particularly if they are sensitized to urushiol, without ever coming in direct contact with the plant.
Teach your children to recognize plants in the Toxicodendron family. Poison ivy is a vine that either climbs vertically or spreads out through grasses. In the summer, leaves are green, while the plant may have red leaves and white berries in autumn. It is found in wooded areas, but also along rivers, lakes and ocean beaches. Even dead plants can cause an allergic reaction. Poison oak, while less common in Virginia, has leaves that resemble oak leaves.
There are three leaflets, but sometimes up to seven in each leaf group. Poison sumac, more common in swampy areas such as Florida, grows as a shrub or small tree with 7 to 13 leaflets on each stem. While being familiar and avoiding contact with the plants is great protection, it is important to take further precautions, particularly when hiking or doing yard work. Long sleeves, long pants or tall socks provide a layer of protection between the oils and your skin. Heavy vinyl gloves are recommended for yard work that involves handling brush.
Remember to remove and wash any clothes that may have had contact with the plant as soon as possible. Washing with mild soap and water within 4 hours of exposure may prevent the rash from developing.
Be sure not to scrub the skin, as this may make the skin irritated and more susceptible to rash. They leave a clay compound on the skin and must be applied every 4 hours. Once the rash appears, there are many home treatments that will ease the itching and discomfort. Soaking affected skin in oatmeal baths or the use of cool, wet compresses may provide temporary relief. Lotions containing menthol or phenol calamine may help when applied to the rash.
Antihistamines taken orally may not provide much relief from the itching, since the itch from poison ivy is not due to histamine. These medicines may sometimes be used if the itching is interfering with sleep, since the most common side effect of antihistamines is drowsiness. Avoid the use of topical antihistamine creams, products intended to numb the skin such as benzocaine, or topical antibiotic ointments.
These all have little benefit and may have concerning side effects. The use of topical corticosteroids may be helpful in easing the inflammation and itching that accompanies the rash. Using this medication as an ointment preparation may feel better on the skin than a cream. We will evaluate for signs of infection and prescribe oral antibiotics if needed.
We may also treat the more severe dermatitis with oral steroids. It is important to remember, however, that most cases of poison ivy dermatitis do not require the use of oral steroids, which have some unpleasant side effects themselves. For severe cases, steroids are tapered over two to three weeks. If your family takes protective actions and knows what to do immediately after accidental exposure, hopefully no one will suffer from the itchy consequences of urushiol!

Antihistamines taken orally may not provide much relief from the itching, since the itch from poison ivy is not due to histamine. Treatment of mild to moderate rash includes application of cool compresses or diluted aluminum acetate solution, such as Burow's solution, or calamine lotion. Use of topical antihistamines and anesthetics should be avoided because of the possibility of increased sensitization. Early application of topical steroids is useful to limit erythema and pruritus.
However, occlusive dressings should be avoided on moist lesions. Refractory dermatitis can be treated with oral corticosteroids such as prednisone, with an initial dosage of 1 mg per kg per day, slowly tapering the dosage over two to three weeks. Shorter courses of steroids may be followed by severe rebound exacerbations shortly after drug therapy is discontinued. Oral antihistamines may help reduce pruritus and provide sedation, when needed.
The authors conclude that prevention requires educating patients to recognize the offending plants and to wear protective clothing when engaging in outdoor activities. Desensitization efforts are of uncertain value. The success of topical barrier preparations is variable, but some, such as organoclay preparation, can limit response in exposed susceptible persons when applied to the skin at least 15 minutes before anticipated exposure.
Application should be repeated every four hours if exposure is prolonged. This content is owned by the AAFP.

No published studies compare varying durations of treatment with steroids for contact dermatitis due to plants, including rhus.
