After further research, it looks like mepitel and mepitel one are very similar. However, mepitel film looks more like a tegaderm with a paper border and thinner. Now I'm worried that I got the wrong one. I got mepitel one. But I see the photos on this thread that @sessioja used mepitel bought from Amazon. @svb , you mentioned that you got mepitel film at the Mayo Clinic store in Rochester. Ugh... I don't live near there. And I can't find it on amazon. Ebay has it from Australia or UK. All my internet searches seem to find mepitel and mepitel one for sale, but not mepitel film. I'll see what my doctor says. I'm afraid I might have to start treatment without it.
