Hi Maggie,
I had daily Erbitux (and Cisplatin) and daily Ethyol shots.
The Erbitux caused a huge outbreake of pimples on my chest, upper back, and worst of all my face (even inside my nose). They were eventually cleared up by steroids and oral antibiotics (I took them through the end of treatment). The Erbitux was also thought to have contributed to severe radiation burns on my neck which appeared primarily after the end of treatment. I just used aloe cream on them and they healed fairly quickly.
The Ethyol was given daily by a shot in my upper arm (back side of my triceps in the fatty tissue). It is intended to help save salivary function. The shots were nauseating, however, and I took Zofran which worked pretty well for me. My saliva is pretty good at this point - I'm 9 months out of treatment and take Evoxac (which is a saliva stimulant). For me, I think it worked well.

Best wishes,
Chris
