Okay, my oncologist wants me on Tarceva in addition to my being on Avastin for the past 8 months. Yesterday he said my multi-tiny tumors in both lungs had increased 10% in size and I have two new ones. He warned me that my Medicare Part D drug plan had to approve my taking Tarceva and that they might ask me to pay as much as $3,500. for the first month's supply of pills, shipped Fed EX from the drug company. Tarceva is being used for lung cancer "off label". He said that I needed to challenge the cost and see what I could get them to accept. We are not poor but we do not have $3,500 floating around each month for meds. Have any of you had experience with "the phone call" from the Part D people over you doc Rx this med for you? Did you resist their first price request...what was the result? Thanks for any help you could be on this. cynthia from Mo.
