My husband is on triple therapy, with docetaxel. He is also stage 4 metastatic.
He is tolerating it fairly well (2 treatments of 6 so far). He feels a bit unwell and fatigued for about the 2nd day after to about the 6th day after, but nothing major.
He is on a steroid for 3 days (the day prior through the day after treatment).
The science for chemo has come a long way from my understanding. It’s not anywhere near as bad as we thought it may be.
Good luck to you!
