Poison Ivy Rash
Understanding Poison Ivy Rash
Poison ivy rash is an allergic reaction to urushiol, an oily resin found in poison ivy, poison oak, and poison sumac plants. The rash appears as red, itchy, and blistering skin within 12 to 48 hours after contact with the plant. It can affect any part of the body that comes into contact with the oil, and the rash can spread if the oil remains on the skin, clothes, or other surfaces.
While poison ivy rash usually resolves on its own within 1 to 3 weeks, severe cases may require medical treatment. Over-the-counter creams and antihistamines can help relieve mild symptoms, while prescription medications might be necessary for more severe reactions.

Poison Ivy Rash FAQs
Poison ivy rash is caused by an allergic reaction to urushiol, an oily resin found in poison ivy, poison oak, and poison sumac plants.
Symptoms typically appear within 12 to 48 hours after contact with the plant and include red, itchy, and blistering skin.
Treatment includes washing the skin thoroughly, applying over-the-counter creams and lotions, taking antihistamines, and using prescription medications for severe cases.
The rash itself is not contagious, but the oil can spread if it remains on the skin, clothing, or other surfaces. Washing thoroughly can help prevent spreading.
Avoiding contact with the plants, wearing protective clothing, and using barrier creams can help prevent poison ivy rash. Learning to identify the plants is also essential.
Seek medical attention if the rash is widespread, severe, or accompanied by difficulty breathing, swelling, or signs of infection such as pus or fever.
