Hi Tonya,
I started treatment with tamoxifen, until it was definite that I was post menopausal. Because I had had some break through bleeding during my 3 months on HRT, the onologist couldn't be sure it wasn't menstral. A hormone blood test showed that I was almost menopausal, but not completely. I had to take the tamoxifen until it was definite that I was through the change. That was in August last year, and so I was then changed over. My oncologist reckons that the aromotase inhibitors are the best option once menopause has been reached, prior to that, tamoxifen is best. Having said that, tamoxifen is tried and true and still a good drug, which has been used successfully for many more years than these newer drugs. I think that they swap you back to
tamoxifen if side effects are too bad, or there are
problems with bone density. I don't recall having side effects from tamoxifen. My hotflushes changed a bit, but
I have been having them for so many years, that it was hardly noticed. Love Chris xx
