HOME CARE ADVICE FOR MILD POISON IVY
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).
Cut the fingernails short and discourage scratching to prevent a secondary infection from bacteria.
