Fluocinonide
"Works very well for contact dermatitis etc., better than any store bought cortisone. One rash I had for years was cleared in 1 use. Now I use on occasion at first signs of re-occurrence. I had some conditions that it did not help.  If it does not clear in a week or so, get the doctor to do some kind of test to find out whats really wrong (most likely virus or fungus). 45 year white male.  No obvious side effects."
