Friend of mine was being treated with Keytruda. Worked on the cancer but attacked her liver. This article is helpful.
I take Keytruda. I was taking it every 3 weeks, then my dr. changed it to every 6 weeks, but with a larger dose. Once he did this, I developed itchy rashes all over my torso and groin. Drove me crazy. He put me on Prednisone and that helped a whole lot, and then he moved me back to every 3 weeks. I have about 6 months left then I’m done. at least I don’t have to get chemo.
