I found it to be much better; much reduced side effects of joint discomfort and insomnia. It can be purchased at online Eagle Pharmacy for 60.00/ month including shipping- no insurance so out of pocket . Your onco team can set it up with the pharmacy. Sealed Bottles FAR from expiration date and come from Brand manufacturer of Arimidex! My onco doc suggested this option to me… otherwise 1,700./ month at cVS.
