I have been on
arimidex for about 2 months (since Feb. 2009), switched from tamoxifen after 1 year on tamoxifen. My white blood cell count the month before I started arimidex (Jan.) was 4.2. When I had a blood test more than 2 weeks ago (April 8), my WBC count was 3.3. Could this be a side effect of arimidex?
FYI -- I was diagnosed in May 2007: IDC, stage 1, 1cm., e.r. +, grade 3, negative lymph nodes. I had chemo (1 infusion TC, 6 infusions CMF) Aug. 2007 to Jan.
