Take an over-the-counter antihistamine as soon as you discover the poison ivy rash. Refer to the packaging for dosage information.
Soak a clean towel in cool water and baking soda, drape it over the rash, and leave it there for up to 30 minutes. Apply compresses several times a day.
Take a short, cool bath with a soothing oatmeal additive. At the end of the bath, wash the rash with a tiny amount of gentle, deodorant-free soap.
Step out of the bath, gently blot the rash with a towel, and apply a nourishing moisturizer to your damp skin. Use a gentle, fragrance-free product to avoid irritating the rash.
Leave the affected skin bare until it absorbs the moisturizer, then cover it with loose cotton clothing.
