Hi @Red1,
I took Tamoxifen for just over 4 years and tolerated it quite well. I was 54 and post menopausal when I was prescribe it!
Main side effects for me were: fatigue ( I have still managed to work full time tho), and endometrial problems which required 3 hysteroscopies.
This year my surgeon thought it would be best if I swapped to Arimidex because of increased risk of endometrial cancer on Tamoxifen.
I have found Arimidex okay so far, however had osteoporosis prior to starting so now having Prolia injections to help with this.
Your body, your choice, however for me, even tho the percentage of benefit may not be huge, it is still a benefit and I really want to give myself every chance at keeping this shitty disease at bay.
All the very best whatever you decide.
Michele
