Allergic Contact Dermatitis Treatments

If Exposed:

If you have been exposed to poison ivy, oak, or sumac, wash your entire body immediately. You can reduce your chance of getting a rash if you wash thoroughly with soap and water within 10-15 minutes of exposure. Using alcohol and water, wash all clothes, tools, and shoes that were in contact with the plant. One small study shows that cleaning with the oil-removing compound “Goop” or the poison-ivy prevention substance “Tecnu” is more effective than using soap alone. All three treatments reduced the occurrence of skin rash by more than 50% following contact.

If Rash Develops:

If a rash develops, the itching and blisters will usually disappear in 7-14 days without treatment. Treatment to reduce discomfort includes:

• Cool compresses with water or whole milk
• Oral antihistamines
• Over-the-counter medications:
  • Calamine lotion
  • Zinc oxide or baking soda (to dry oozing blisters)
  • Diluted aluminum acetate solution (Burow's solution)
• Steroid medications:
  • Cortisone creams—can relieve symptoms and may also shorten the duration of the rash
    • These are available over-the-counter (much weaker) and by prescription.
  • Oral corticosteroids—may be prescribed in severe cases

If you are diagnosed with a rash from poison ivy, oak, or sumac, follow your doctor's instructions .
