I have been on anastrozole for a month now and have little side effects if any. My problem is that i am already in full osteoporosis and the anastrozole is only going to make that worse. My dr first suggested taking tamoxifen but that makes me nervous because of all the possible problems-stroke, blood clot, uterine cancer, etc. I also have a major problem in my mouth with my teeth that need treating but I can't be on osteoporosis drugs while doing dental treatments. Ugh! What to do?!
