How can you prevent the rash from poison ivy, oak, and sumac?
If you think you have touched any of these plants:
Wash your skin right away with plenty of water and mild soap (such as dishwashing soap) or rubbing alcohol. Rinse often, so that the soap or rubbing alcohol doesn't dry on the skin and make the rash worse.
Use a brush to clean under your nails.
Wash any clothing or other items that might have the oil on them. Do it right away.
Wear long pants, long sleeves, and closed shoes to help keep the oil from getting on your skin.
Wear vinyl or leather gloves. Rubber (latex), cotton, or wool gloves offer no protection.
Use a barrier cream or lotion that contains bentoquatam (such as IvyBlock). It can help keep the oil from coming in contact with your skin.
Wash well or throw away anything that came into contact with the plants.
Experts say not to burn plants like poison ivy, oak, or sumac. When these plants burn, urushiol attaches to smoke particles. Exposure to the smoke can cause a rash on your skin. Breathing in the smoke can also hurt your lungs.
