Answer
Poison Oak and Poison Ivy are essentially identical first-cousins - both are well known and common causes of intense, itchy skin eruptions that can blister and weep. Over-the-counter remedies do little more than provide minor soothing and the reliance upon them typically only delays more definitive treatment. The sooner that a prescription for a more potent steroid cream can be administered, the less likely it is that the rash will spread.
Another misconception is that the rash from stinging plants is spread from contact. This isn't true. The spreading rash is simply a manifestation of the allergic response occurring throughout the body.
When it comes to stinging plants, an ounce of prevention is worth a pound of cure. Wear gloves, socks, pants and sleeves when you cannot avoid the plants.
