Enzalutimide is a drug which several years ago was hard fought over to get NICE approval. It is quite expensive and well worth giving it a go. You take 4 (very large) capsules daily, so no needles or drips!
Although I only had eight months of it before it stopped working, it initially brought my PSA right down.
The main side effect for me was the usual tiredness, although was not as bad as Docetaxel or Cabazitaxel. It allowed me to have as near normal life as possible and it was great not having to visit the hospital for regular chemo.
Although I did not have it as long as I would have liked, men on this forum have been on it for a considerable period so I would not hesitate in telling you to embrace the opportunity and regain some of your life back!
