You've likely heard the saying "leaves of three, leave them be," but accidental brushes with poison ivy, oak, and sumac happen to even the most careful of outdoors enthusiasts. An example of contact dermatitis, the rash is caused by an allergic reaction to urushiol, an oily resin present in all parts of the offending plants. If you find yourself afflicted with the telltale itch and blisters of poison ivy, keep these treatment tips in mind:
1) Wash it off.
As soon as possible after exposure, soap up in the shower using lukewarm water. This will help remove any remaining oil that might be present on your skin. Before you hop in the shower, though, toss your clothing into the washing machine. If you don't, the oil poses the threat of infecting you—or someone else—upon contact later on.
2) Ease the itch.
Popping an antihistamine can help alleviate your symptoms. Cold compresses and oatmeal baths are also known to reduce the itch, especially when followed by an application of calamine lotion or hydrocortisone cream. As tempting as it might be, resist the urge to itch, as aggressive scratching can cause infection!
3) Call your doctor.
If your rash becomes infected, you have a fever, or if your rash affects a large area of your body, seek the advice of a medical professional.
