Contact with poison sumac causes an itchy, irritated rash in seven out of every 10 people who are exposed to it, according to The Children's Hospital of Philadelphia. If you take quick action, you may be able to prevent a rash from developing. As soon as you realize you have been exposed to poison sumac, rub the exposed skin with a cloth moistened with rubbing alcohol. Rinse the area and wash with soap and water. You will know within 48 hours if your exposure has caused a rash. If a rash develops, you can treat it at home or visit your health care provider.
Step 1
Soak the affected area in cool water, or apply a cool compress, to ease itching. Moisten a washcloth in cool water and squeeze the excess moisture out to make a compress.
Step 2
Take oral, over-the-counter antihistamines. Antihistamines can ease itching and make it easier to rest.
Step 3
Visit your health care provider. He can provide a prescription for oral corticosteroids. You will need to take these for two to three weeks. If you stop taking the medication too soon, your symptoms can reoccur.
Tips and Warnings
- Do not scratch the rash. While poison sumac will not spread by scratching, you run the risk of developing an infection if your hands and fingernails are not clean.
