How to Treat Poison Oak Rash

Poison oak can be guilty of causing itchy rashes and skin irritations similar to that of poison ivy. Both plants produce a resin known as urushiol, and contact with the resin is responsible for the common allergic reactions most people suffer. Identifying poison oak may be the best way to avoid having to deal with allergic reactions, and the severity of the reaction may depend on the nature and extent of the contact as well as the individual. Some cases of poison oak may be severe and require prescription medications and medical treatment, but most symptoms can be treated effectively with over-the-counter medications.

  Apply a cool, wet compress periodically to the affected area to reduce swelling and itching, and to absorb any fluid from the rash. Change the compress regularly to avoid infection of any open sores.
