User:I was exposed to poison oak 2 weeks ago. I have a bad rash on legs and arms. Is there something I can use to stop the itching and spread of the rash?
Doctor:Hello
User:HELLO
Doctor:You could use Cetrizine tablets twice a day
User:Do I need a perscription?
Doctor:that would reduce the itching
Doctor:No
Doctor:Cetrizine is available OTC
Doctor:if that is not available you can use Benadryl as well
User:I applied tecnu and that was suppose to stop ich and spreading of rash ... but it does not work
Doctor:that is also equally effective
User:I have been taking Benadryl ... no result
Doctor:Do not apply anything locally except an antibacterial cream such as Neosporin
Doctor:oh okay
User:I have used tecnu daily ... rash spreading and still itching
Doctor:in that case you will need to see a dermatologist
User:you can offer no advice?
Doctor:I am not well versed with such cases as we do not encounter this particular problem in our country
Doctor:poison oak is not present in this part of the world
Doctor:hence I would not be the right person to guide you
User:I seem to know more about poison oak that you do. I will try a local doctor. This site has offered no real advice. thanks anyway
Doctor:As far as I know
Doctor:the rash is an allergic reaction to urushiol
Doctor:the rash may appear as spreading, but usually the rash is still developing because of the initial contact itself
Doctor:You need not use special cleanser to clean the skin
Doctor:you can clean the skin with normal soap and water
Doctor:that will be sufficient
Doctor:And since it is an allergic reaction, antihistamines such as Benadryl or cetrizine should help
Doctor:if these do not help, then you can go for a short course of steroids
Doctor:And steroids are available only on prescription
Doctor:that is the oral tablets are available on prescription only
Doctor:you can use topical steroid creams such as flutivate locally
Doctor:This is what I know about poison oak contact dermatitis
Doctor:If you need further information, you may please see your local skin specialist
Doctor:k
Doctor:Thanks for consulting me here
Doctor:take care
Doctor:and bye for now
