[…] If your rash is mild and on a small section of skin (and you know it’s from poison ivy), the AAD says you can feel free to treat it at home; if it’s widespread, severe, doesn’t improve in 7 to 10 days, or seems infected, get in touch with a primary care doctor or dermatologist and ask about medication.

[…] If treatment fails and the diagnosis or specific allergen remains unknown, patch testing should be performed. […] A common cause of allergic contact dermatitis is exposure to urushiol, a substance in the sap of rhus plants (e.g., poison ivy, oak, sumac).

[…] This study revealed that oral corticosteroids were prescribed to treat TD at the initial visit for less than half of visits.

  Most prescriptions were for durations of less than two weeks, which is shorter than the recommended treatment duration reported in the literature. […] As the immunologic response to urushiol can take up to 14 days to present in sensitized patients with exposure, TD reactions have the potential to continue to manifest or worsen throughout that 14-day period. […] Thus, shorter courses of oral corticosteroids pose the risk of patients experiencing rebound dermatitis, where signs and symptoms of an acute dermatitis can recur or flare after temporary suppression with an immunosuppressive medication, such as oral corticosteroids. […] Our findings further support and expand on previous clinical trial research. […] This study found that shorter duration oral corticosteroids can be problematic in the treatment of TD both independently and controlling for drug type and treatment location.

  First comes the itching, then a red rash, and then blisters. These symptoms of poison ivy, poison oak, and poison sumac can emerge any time from a few hours to several days after exposure to the plant oil found in the sap of these poisonous plants. The culprit: the urushiol oil. […] The rash will occur only where the plant oil has touched the skin, so a person with poison ivy cant spread it on the body by scratching. It may seem like the rash is spreading if it appears over time instead of all at once. But this is either because the plant oil is absorbed at different rates on different parts of the body or because of repeated exposure to contaminated objects or plant oil trapped under the fingernails. Even if blisters break, the fluid in the blisters is not plant oil and cannot further spread the rash. […] See a doctor if: […] The rash is not improving within a few weeks. […] The rash is widespread and severe.
