Can it take a week for poison ivy to show up?

Answer 1

Poison ivy reactions can begin to appear within just a few hours after contact with the plant, depending on the sensitivity of the individual. Contact with affected animals, clothing or from burning plants may cause similar reactions. It may be helpful to cleanse the skin immediately after being in the woods, before blisters appear. The oily urushiol from these plants causes contact dermatitis, and several products are available on the market to be used after suspected exposure. Soap and water alone may be insufficient to remove this substance from the skin, so many products also contain a base of petroleum distillates to emulsify the oil from the skin surface. A less expensive alternative may be made at home by combining equal parts of liquid detergent with a product like GooGone or bug/tar remover, and using this with warm water in a shower. This is followed by a regular shower with soap alone to remove the residues of the petroleum distillates and urushiol. In children under 2 years old, only soap and warm water should be used. Benadryl (diphendydramine) creams or lotions applied afterwards will help reduce the itching after exposure.
