Does poison oak cause an allergic reaction upon skin contact?
Patient's Query
Hello doctor,
I play golf in an area where there is a significant amount of poison oak. I would like to know how quickly urushiol binds to the skin and whether it can spread once it has bound. I use an electronic cigarette that requires me to handle cotton, which I feed into the atomizer. My concern is whether urushiol can vaporize and, if so, what harm that could cause.
Please help.
Thank you.
Hello,
Welcome to icliniq.com.
I understand your concern.
Poison oak causes allergic contact dermatitis (ACD) and is the most common cause of ACD compared to all other causes combined. The allergen responsible for ACD is typically found in the sap called urushiol, which is mainly present in the leaves and inner stems of the plant. Symptoms usually appear 12 to 48 hours after contact with any part of the plant. However, the resin binds immediately to the skin upon contact, so it should be removed with a mild soap wash as soon as possible. If washing is done within 10 to 15 minutes of contact, up to 50 percent of the urushiol can be removed. Washing after one hour is less effective.
You can use bentonite barrier creams to prevent urushiol from binding to exposed skin. Once urushiol is bound to the skin, it does not vaporize or spread to other parts of the body. Since it is a local reaction, the severity depends on the amount of resin that comes into contact with the skin.
I hope this helps.
Thanks for using icliniq, and have a nice day.
