I wanted to add an update to this thread. I began Apalutamide just over a week ago and, so far, no major side effects. When I signed the consent form, there was a long list of possible and very scary side effects. I was already experiencing hot flushes from the Zoladex and these have not increased noticeably, although I have been taking Medroxyprogesterone for a couple of months to help with these. My fatigue seems slightly worse, but I am factoring in the hot and humid London weather, so this might improve once cooler weather arrives. I have experienced some dizziness - not the weaving about, falling over kind - but noticeable and unwelcome.
My next PSA test is due later this month, and I am hoping for a reduction. It has continued to double every two months. I will update once more when I learn the results.
