Yes, it's an MAOI. It's a patch which means it's a little easier than other MAOIs because it does't go through the digestive tract with the foods that can cause issues.

It's been around for about 10 years but a lot of drs seem afraid of it because it is an MAOI. I've been on it for 6 and Wildflower is the first person I've ever encountered on it. (Just realized that ). For me it has been a life changer; the only other AD that ever worked for me over time after my diagnosis was imipramine but the dose had to be so tightly controlled that it was ridiculous and eventually I needed more than I could handle and that left Emsam. Now there are a few ADs that I haven't been on but hopefully Emsam lasts for a lot longer (my pdoc says that she hasn't seen anyone really have it poop out on them; there was concern about that for me for a bit last year but it wasn't that, it was my AP which was what I thought all along; it just was hard to be sure b/c I got more depressed than usual as it started to fail and then as there were a lot of changes as we tried to stop a sinking ship. But Emsam seems to be fine now).
