Ricky ....
I do have some experience with the Zytiga and its costs. I was on Zytiga in 2012 for a total of 5-months ... along with prednisone at 10mg daily. I am on medicare and do have part D coverage .... and did at that time also.
Costs ... thru Part D:
My first month cost me $2600. BUT the
Second month was much less (about $500.) because of the donut hole.
The third month was around $350. as I was approaching the next phase.
And from there on, it was about $250. per month after the above phase.
I think the second phase is "disaster" phase or similar and phases in at around after $4500. has been spent in a given year.
So, the first month is very expensive ..... then the Part D really does help. What seemed like it might cost close to $30,000. at $2700. per month ...... really should be closer to $6000. with the greatly declining costs after the first month.
In 2012, my total cost of meds (out-of-pocket) were $6000. and that included some expensive inhalers like Spiriva and Advair + 5-months of Zytiga + all my other meds for the year.
Please double-check his insurance coverage for Part D.
Peace and wellness
