For several months, I was on an Avastin + Erbitux regimen. The Erbitux gave me a horrible rash on my face, scalp, chest and shoulders. I stopped using Erbitux in mid-April, and the rash is much less than it used to be, but still visible. I still look like I have an acne/rosacia problem. I expected it to go away after a couple of weeks when I stopped taking it, and now more than three months later I still have this rash! I'm beginning to wonder if it's permanent scarring. Has anyone had an Erbitux rash that eventually went away? How long did it take?
