Yes. It's extremely expensive.
My mom lost her medicaid and couldn't receive it. She is on it now because of two things:
one, I looked into a Medicare part D subsidy. She qualified and as a result, my mom paid $3 for the revlimid and then went into catastrophic mode and paid nothing for it. Unfortunately she lost her subsidy at the end of last year which leads me to...
two, There is a foundation called the Chronic Disease Fund. It offers assistance to people with Myeloma and will take care of the copay for you if you qualify. This has enabled my mother to continue to take the revlimid.
Good luck. Let me know what happens.
