Judi, I haven’t had any noticeable side effects from Letrozole, and none from Anastrole ten years ago.
Any changes I’ve experienced are the “regular ones” related to menopause, and I had those almost ten years earlier than when I started Anastrozole in 2015.
I lost nearly all taste during chemo. I’m several months out, and still not great, but lots better.
