Most rashes caused by poison ivy, poison oak, or poison sumac are mild and last from five to 12 days. In severe cases, the rash can last for 30 days or longer. Immunotherapy is not available for allergies to poison ivy, poison oak, and poison sumac.
The good news: If youâve been strolling around poison ivy, you may be able to avoid the rash if you wash with soap and water within 15 minutes following contact. QUESTION: How long does poison ivy stay active on clothes, shoes, gear, etc.? ANSWER: Poison ivy, poison oak and poison sumac all contain the same substance (toxicodendrol or urushiol) that causes the blistering, itchy rash that appears 12 to 72 hours after direct contact with these plants. The invisible sap can remain active on your clothes, shoes, tools or petâanywhere it landsâfor several months.
