Im sorry I havent had Erbitux. Hopefully someone who went thru it will check in soon.

From what I understand about Erbitux, the more of a rash the patient gets the better its working. It sounds very uncomfortable to me. Would benedryl work to help control the itching? Be careful, you dont want to get too dried out from using it so check with your doc. Stay in air conditioning so you arent outside in the heat, sweating would probably make it worse.

Good luck!!!
