What plants cause similar allergic reations to poison ivy?

The viney plant I thought was poison ivy for years has five leaves. Somebody told me the plant is virginia creeper. Poison Ivy only has three leaves. I know everytime I get near the stuff at my mom's house, I break out into a rash with little blisters. I found this viney five-leaf plant in my yard and I want to get rid of it. But I don't want to have to deal with the allergic reaction. When I know I got in contact with this plant, i wash up with soap and water right away. But I still get it. Does anyone know of a plant that looks like Virginia Creeper that can give you a rash like Poison Ivy?

What plants cause similar allergic reations to poison ivy?
Typically there are two other plants that create similar rashes to poison ivy, which are poison oak (occasionally has a more red tint, but also has 3 leaflets) and poison sumac (slender leaves with 7-13 leaflets). All are considered Toxicodendrons. Often poison ivy is mistaken for Virginia Creeper. If it is neither, perhaps you just have a personal allergy to that specific plant.

Reply:In the most tangled areas of my yard, Virginia creeper often grows in proximity to stinging nettle. Stinging nettle can produce areas of extremely itchy, blistered rash. Washing up with soap and water immediately should help, but be sure to let the water run over the affected area...as in showering, NOT bathing. Soaking or bathing will just spread the "sap" that causes the problem.
