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 duration of a poison ivy rash depends upon the person's sensitivity and how the urushiol is absorbed in the skin. Generally poison ivy rash lasts for a week or two but in some cases it might take as long as four weeks for the rashes and inflammation to subside. If by any chance the poison ivy plants are burned and the smoke gets into the nasal passages, the rash will appear on the lining of the lungs causing pain and difficulty in breathing.
