Good morning everyone. Whenever someone posts their side effects of Arimidex (Anastrozole), I realize I'm not alone. I'm 74 and tend to think, "Well, this could be a result of my age", but it turns out that many people on Arimidex are experiencing the same side effects. I've been taking it for a year and a half now. I won't change to another drug because from the posts I've read here, they all seem to have similar or worse side effects. In a recent conversation with my Oncologist I told her I had read that Arimidex seems to have the best success at preventing a recurrence and she agreed. My question to all of you is has anyone who has also taken Arimidex for awhile had a recurrence of cancer?
