There is help is the payment of this drug.
My father has stage 4 lung cancer. He started on Tarceva one week ago. There is a very large hand out booklet that your oncologist should supply you. In that handout is a section about help with payment of the drug.
There is a telephone number within that information. Please call that number and talk to people. This is a a very expensive drug and there is help for you. My parents are in their seventies and my mother handled the phone conversation. Within days the drug was shipped directly to their front door.
I hope this helps you and I pray for you, your wife and your family.
