There is no cure for the poison oak or poison ivy rash once it begins, but if you focus on relieving the symptoms you can stop poison ivy itching.
The first step is to remove urushiol from your skin. Be sure to wash the area with Tecnu Extreme Poison Ivy Scrub or Tecnu Original Outdoor Skin Cleanser to remove and help prevent spreading the rash-causing oil.
Minor itching, pain, oozing and swelling caused by poison ivy and oak can be relieved with over-the-counter anti-itch treatments such as Calagel Anti-Itch Gel or homeopathic Tecnu Rash Relief Spray. In severe cases, a physician can prescribe antihistamine creams, tablets or shots.
Remember to avoid further contact with the plant oil if possible. You can clean your tools, clothing and pets that have been exposed with Tecnu Original Outdoor Skin Cleanser to avoid recontamination from the urushiol oil.
