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.
School of Medicine, Family Medicine answered. If you have come in contact with poison ivy, you should cleanse your skin with soap and water within five to 10 minutes. After that time the urushiol oil (chemical that causes the reaction in poison ivy) will have penetrated the skin. If you have been exposed, certain creams can absorb the urushiol to help prevent reactions.
