JayAnn, the Erbitux rash is very hard to control. Do you know if they are giving him Benedryl or anything else right before they start the Erb. infusion? Ask about that. My only other suggestions are in the post above. The good news is that it will go away after the tx. is done. Having to deal with the rash and radiation at the same time must be really tough.Push his Docs for some help. Amy in the Ozarks
