HOME CARE ADVICE FOR MILD POISON IVY
And remember, contact your doctor if your child develops any of the "Call Your Doctor" symptoms.
- Steroid Cream: Apply 1% hydrocortisone cream (no prescription needed) 4 times per day to reduce itching. Keep the cream in the refrigerator (Reason: It feels better if applied cold).
- Local Cold: Soak the involved area in cool water for 20 minutes or massage it with an ice cube as often as necessary to reduce itching and oozing.
- Antihistamines: If itching persists, give Benadryl (no prescription needed) orally every 6 hours as needed (see Dosage table).
- Avoid Scratching: Cut the fingernails short and discourage scratching to prevent a secondary infection from bacteria.
- More Poison Ivy:
- If new blisters occur several days after the first ones, your child probably has ongoing contact with poison ivy oil.
- To prevent recurrences, bathe all dogs or other pets.
- Also, wash all clothes and shoes that were with your child on the day of exposure.
- Poison ivy or oak is not contagious to others.
- The fluid from the blisters or rash cannot cause poison ivy.
- No need to miss any school or child care.
- Expected Course: Usually lasts 2 weeks. Treatment reduces the severity of symptoms, not how long they last.
- Call Your Doctor If:
- Poison ivy lasts for over 3 weeks
- It looks infected
- Your child becomes worse
