How to Diagnose and Treat Poison Ivy Rash?

How to diagnose and treat poison ivy rash?


You are able to diagnose your rash by simply looking at it. No test is needed.


Self-care methods are enough for poison ivy rash treatment:

  • Apply an over-the-counter corticosteroid cream for the first few days.
  • Apply calamine lotion.
  • Take oral antihistamines, such as diphenhydramine (Benadryl, others).
  • Soak in a cool-water bath containing an oatmeal-based bath product (Aveeno).
  • Place cool, wet compresses on the affected area for 15 to 30 minutes several times a day.

The rash usually goes away on its own in two to three weeks. If the rash is widespread or results in a large number of blisters, an oral corticosteroid, such as prednisone, may be prescribed. If a bacterial infection has developed due to the rash, an oral antibiotic may be prescribed as well.
