I posted a message about my mom earlier and received no reply. Please tell me if there are similar cases of Tarceva side effects. Mom was told to stop the Tarceva now at 75 mg because of intense rash, burning, itching and pain. She looks scalded and her skin in so tender it bleeds very easily when she rubs it ---scratches gently. She can't sleep due to the itch --. The rash is everywhere yes-everywhere. Any advice.
