What is a Poison Ivy Rash? (Symptoms, Causes, Treatment, Prevention)

A Poison Ivy Rash occurs when a person comes in contact with a poison ivy plant. Or they come into contact with a person or object that has touched poison ivy. It's also possible to inhale burned particles of the plant. It's either a small shrub or a trailing vine, depending on the area it's found. The rash is an allergic reaction to a substance found in the plant. This substance is known as urushiol and it is an oily resin. All rashes can vary from persons to person by plant to plant. Some people have a much stronger allergic reaction than others.

What are the Symptoms of Poison Ivy Rash? Poison ivy rashes can cause severe and intense itching and burning pain. Depending on sensitivity, symptoms may begin slow or quickly. However, the rash and symptoms develop between 12 and 48 hours after exposure. The rash will often occur in a straight line but can spread out. Redness, swelling, and blistering can occur. In severe cases, the blisters may ooze pus, or the person may develop a fever. If inhaled, difficulty breathing may occur which requires swift medical care.

What Causes a Poison Ivy Rash? Urushiol is found in the roots, leaves and stems of the plant. There are several common ways that people can come into contact with urushiol. They can directly touch the plant. Another common way is to contact the oil by touching a contaminated object. The oil can transfer to nearly anything. The oil can cause a reaction years after it initially contaminated the object. When poison ivy is burnt, the smoke contains urushiol. Inhaling it can cause irritation and damage to the nasal passages and the lungs. Fluid from blisters do not contain urushiol and will not cause a reaction.

How is a Poison Ivy Rash Treated? The treatment for a poison ivy rash depends on how severe it is. Most rashes can resolve with minimal treatment and self-care. Wash exposed skin, remove and wash clothes to prevent spreading of the rash. Over-the-counter antihistamine medications can help reduce the severity. And lessen the immune system response to exposure. Corticosteroids can also help to reduce inflammation and clear up the rash.

How is a Poison Ivy Rash Prevented? Poison ivy rash is prevented primarily though preventing exposure to the oil. Learning to identify the plant is the best way to avoid it. When walking in areas with plants, prevent exposure by covering skin. Wash all objects you suspect may have come in contact with poison ivy. Use barrier creams that catch the resin and prevent it from causing a reaction.
