HI there Hope213, I've been having 3 monthly Prostap injections for just over a year now through my GP - Prostap is effectively the same thing as Zoladex. I was already on Tamoxifen and wanted to knock my estrogen right down by turning off the estrogen from my ovaries. For me the side effects were worth it for that peace of mind I gained from Prostap. Tamoxifen along with one of these gonadotrophin-releasing hormone analogues (GnRHa) is not an easy drug combination by any means - my breast care team don't routinely recommend it hence why I had to go to my GP to get Prostap and luckily he was on board with this. Like you I found that it took a few weeks for that 1st Prostap injection to kick in but when it did I knew about it. I'd had it quite easy just on Tamoxifen to that point but bring in Prostap to the party as well and it became full on - lots of hot flushes, lots of cold shivers, very bad headaches that could last 48 hours or more, difficulty sleeping - those were the main ones. However our bodies are really very good at adjusting - never under estimate that - I'm not saying I got rid of all those side effects but after my 2nd injection (mine were every 3 months) I was tolerating them a lot better. There was always a bit of a hit a couple of weeks after the injection as it all kicked in again but thankfully the headaches went as they were quite debilitating. The rest of it - flushes, shivers, difficulty sleeping - I've adjusted things to try and help with these - like my mattress, my bedding, etc - even trying to practice some mindfulness in the middle of the night when I can't sleep - I'm not great at it but it did help. Hope this helps - take care + look after yourself x
