Femara

After I finished chemo and surgery, my med onc prescribed Femara for me.  I was expecting Tamoxifen, but he said that a recent, large study had shown the aromatase inhibitors were significantly more effective in preventing recurrence with estrogen receptor positive cancers, and that the clinic where he works had switched over from using Tamoxifen almost entirely.  However, when I looked up the study, I found that the drug used in it was Arimidex.  Are these two drugs so similar that we can extrapolate the same effect, or do you think I should ask to take the drug that was actually studied?

Dear Jo2:  These two drugs are very similar.  It is probably safe to extrapolate the same effect.  However, if you would feel better, you could request a switch.  Your prescription coverage may prefer one over the other.
