Erbitux is a biological drug used in treating cancer. It is easier on your system. There are some people who have a reaction to Erbitux. They usually give benedryl before it. It's possible you could have a rash similar to acne on the face. My mother did not have the rash on her face. After a year of Erbitux she did a rash on legs and arms. Not bad gave her benedryl. Tolerated it well.
Cisplatin is hard Chemo. After the first treatment my mom had her voice back. Tumor disappeared on her voicebox. There are some bad side effects. The nausea, loss of taste, and loss of hair. You may also at some point down the road deal with numbness of toes, feet and hands (neuropathy). Tell your doctor right away if you start experiencing this. They have medicines to help. They will always give you medicines to help with the side effects of Cisplatin.
My mother was given both at the same time. They work well together the first go round. Unfortunatly my mother cancer has come back in her mouth. The Cisplatin was stopped in May because my mother was too weak to take any more. She continued on Erbitux until 3 weeks ago. She is now on taxotere.
I hope this helps in some way. This has been our experience with these drugs.
Best of luck.
