Understanding and Treating Exposure to Poison Ivy
Summer is almost here and Texans will be spending more time outdoors enjoying the weather. Unfortunately, this means less protective clothing and possible exposure to some of the risks of nature, including poison ivy or poison oak. These harmful plants can be found in most parts of the U.S., growing as vines around trees, stretching across the ground, or growing upright in the form of bushes. Resin urushiol, produced by these plants, is a substance that has an unpleasant effect on humans sometimes causing contact dermatitis. This is essentially an allergic reaction to something foreign to the human body. Contact dermatitis occurs in approximately 75 percent of those that touch this type of poisonous vegetation, and about 20 percent of this group may experience severe symptoms from exposure. Poison ivy will generally not pose a great risk to most individuals, but those exposed to it should consider seeking assistance from Austin dermatology services. Washing with soap and water can help reduce the effects of the resin, if done within 30 minutes of exposure. Additionally, many of those who are exposed may not realize that they have come in contact to the plant until 1-2 days later, after the development of a rash. The rash will normally consist of lines of bumps or blisters that may continue to appear for several days, creating the effect that the condition is “spreading” across the exposed area. However, this is actually part of the allergic reaction. The condition will normally heal itself within two weeks, but it can last longer.
Cortisone creams, some of which require a prescription, can help reduce the itching that usually
accompanies the rash, and calamine lotion has been known to bring relief to many victims. Those who
experience a severe rash may require treatment with oral steroids such as prednisone. The most serious
complication posed by exposure to these poisonous plants is the development of an infection caused by
excessive scratching of the affected area.
If you recognize any of these symptoms, seek medical attention from Four Points Dermatology. Poison
ivy treatment is one of the many health services available. A number of other cosmetic and surgical
dermatology services are also provided, covering the wide array of needs of skin care in Austin.
