I've been on Zytiga for 60 days. PSA went from 1.2 to .1 in that time. PSA Mar 2022 was 83.4. Thanks Zytiga. However, some of the decrease can be attributed to after effects of IMRT (39 sessions that concluded 7/8/22) and Lupron.
I am fortunate that Mayo is willing to work with the VA. The VA copay for Zytiga is $8.00/mo.. I hope you can find a less expensive option.
I have good days and bad days due to side effects, Staying active is important but difficult. Today I feel like crap but the results are worth it.
Good Luck.
