With the cost of my Avonex and everything else I am in the gap. I called to reoder my Avonex today and she told me that the cost was $2501.02. Since the gap is $4500 I guess I'll be in it all this month and part of next since I have a couple of meds that are tier 2 and 3. Then my meds will be really cheap! Welll except the Avonex. I'll still have to pay $525. for it. But last month I paid $825. for it. If my DH hadn't have retired I would be paying his insurance cheap copay.
