Bad rash from Filter adhesive- any worthwhile remedies?

Oh goodness, I had this really bad. What products is he using now? He may consider applying a small piece of everything he's currently using to another part of his body and seeing which particular product is causing the reaction. Then cut that thing out of it's something you can go without. I turned out to be horribly allergic to the adhesive remover, and after cutting that out was fine. I also switched from the Hollister appliance to Coloplast, as they're supposed to have the most hypoallergenic adhesives. Initially, though, to calm down my angry skin, I had to see a dermatologist. He prescribed a steroid cream called Clobetasol which cleared up my problem lickety split! Best wishes!
