Suggest Ways To Manage Side Effects Of Tamoxifen And Arimaddex

Hi! I am a breast cancer survivor now for 5 yrs. Thank God. I have been on Tamoxifen and my oncologist is planning on taking me off of it and putting me on Arimaddex. Have there been a lot of side effects from women after 50 yrs. old taking it? I am a very physical women and am hoping this new med. won't slow my lifestyle down. Just curious. Thanks. Sincerely, ML
