Poison Ivy Rash & Treatment

Picture of poison ivy plant

Few things can spoil a summer afternoon faster than a run-in with poison ivy. We here in the Northeast are subject to “eastern poison ivy”—a more dangerous version of its western counterpart that can grow as a shrub or climbing vine. It can be found in wooded areas, by roads, alongside rivers and lakes, and even near beaches in northern states like Connecticut, Massachusetts, and New York.

Poison ivy rash is an allergic reaction to urushiol, an oily resin that’s found in the roots, leaves, and stems of eastern poison ivy. It’s estimated that 85% of Americans are allergic to urushiol, with 10% to 15% of the population being severely allergic. A poison ivy rash can result from a quick brush-up against bare skin and usually appears 12 to 48 hours after contact. In most cases, the rash lasts between two to three weeks.

What Does a Poison Ivy Rash Look Like?

Poison ivy rash often forms in thin red lines after leaves or stems brush against skin. If urushiol is transferred to your skin from a dog or another animal, or if you gather yard waste that includes poison ivy, poison oak, or poison sumac, the rash may cover a larger area of the body.

In many cases, a poison ivy rash can:

  • Cause redness and itchiness
  • Become swollen
  • Blister and become painful

Should I Seek Medical Treatment for a Poison Ivy Rash?

Medical treatment isn’t necessary for mild poison ivy rashes that respond to self-care measures like using over-the-counter ointments and placing cold, wet compresses on the rash several times a day to reduce swelling. However, you should promptly consult with a medical professional if:

  • The rash doesn’t improve after a few weeks
  • Your skin continues to swell
  • Blisters begin to produce pus
  • The rash covers a large area of your body
  • The rash impacts your mouth, eyes, or genital area
  • You experience a fever higher than 100 degrees Fahrenheit

Having a poison ivy rash or inhaling smoke from burning poison ivy can warrant emergency care in some instances. Call 911 or go to the nearest emergency room if you or someone around you:

  • Is having difficulty breathing or swallowing
  • Has swollen eyelids
  • Is experiencing severely itchy skin that does not respond to any treatments

"The overall care I received was excellent! I also appreciate your affiliation with Yale New Haven Hospital."

Derby, CT

"Throughout the visit I felt like the staff really cared. The Doctor took his time talking with me about my symptoms, and I felt like he listened to all my concerns and took that into consideration when recommending the right treatment. Thank you!"

Hamden, CT

"I had to take my son in for an ear infection following a sudden change in temperament at daycare. He was inconsolable the entire car ride but when we got there and by the time we left this care facility he was back to his normal happy go lucky little two year old boy. I highly recommend PhysicianOne Urgent Care."

Westwood, MA

"I wanted to take a moment to thank you for the attention you gave me last week. My son was started on antibiotics and ear drops. Within 24 hours he began to feel better. The poor kid had been going to school in tears because he was afraid of missing any more days, but feeling (and looking) just awful! He's not been able to even think about lacrosse practice, but thanks to starting him on antibiotics, he was thrilled to return to practice today."
