Poison ivy and poison oak are two plants that cause an itchy skin rash. The plants produce an oil that causes an allergic skin reaction to occur. Rashes from poison ivy and poison oak are common in those that spend time outdoors playing or working.
You can develop a rash from exposure to poison ivy or poison oak from a few hours up to a few days after contact with the plant oil. Sometimes pets that have been outside will bring oils in and result in exposure and rash.
Symptoms you may experience include:
- Itchy rash
- Redness and swelling
You should be evaluated by a healthcare provider if:
- The rash covers more than 25% of your body
- The rash affects the eyes, nose, mouth, or genitals
- Red streaks or fever
- Breathing difficulties, hives or swelling develop
