Drugs that work on your immune system. Your doctor may consider these medicines -- such as azathioprine, cyclosporine, or methotrexate -- if other treatments don’t help. There are also prescription creams and ointments that treat eczema by controlling inflammation and reducing immune system reactions. Examples include pimecrolimus (Elidel), which is a cream, and crisaborole (Eucrisa) and tacrolimus (Protopic), which are ointments. You should only use these for a short time if other treatments don't work -- and you should never use them on kids younger than 2, according to the FDA.
For the past 17 months I have participated in the no steroid creme re TSW. Wow, it has been a journey, but I do believe you are correct with all you information. I am still NOT where I would like to be,but probably 60 percent better than with steroid cremes. I live in Switzerland and have have done uva and uvb light therapy as well, and visited Avene thermal spa. I also spent a fair amount of time on the Atlantic ocean trying to heal. So, as I see you have commented on Eucrisa tm.. (criaborole). I would like to comment, that I experienced a severe reaction to the creme after 8 days of use… ( the company Pfizer has my photos etc )
