<<Disclaimer: Verify this information before applying it to your situation.>> I use hydrocortisone (.05%) OTC on small patches of DH. If you are going this route please check with your DR first as cortisone in any form is not a good deal long term or in large amounts. My stuff is called Hydrocort and immediately relieves the symptoms but please check with the DR! Good luck, I only get it on my hands and that is enough. You can get prescription cortisones if the OTC doesn't work. Not medical expertise, just experience so take with a grain of salt. :) Lissy BTW, Hydrocort is a Canadian product, you can probably get the same concentration under different labels depending on where you are from.
