Hi, I looked on the www.erbitux.com website and didn't see anything about bleeding or kidneys, but there is a statement about reactions:
To report SUSPECTED ADVERSE REACTIONS, contact Bristol-Myers Squibb at
1-800-721-5072 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch
You may want to call Bristol-Myers.
I am on Erbitux and have the awful rash. I have not experienced any bleeding.
