Anastrozole Brain Fog

I was on arimidex for 18 months and while I didn't notice the brain fog the joint and muscle pain and insomnia were debilitating. I now have osteoporosis, arthritis and while I am not necessarily thrilled with my decision, I decided to stop taking it. It has been almost six weeks, I am sleeping much better but still have the joint and muscle pain, though less severe. My oncologist and I talked about other brands but they all have the same or worse side effects. I have never had high blood pressure but it shot up at my last visit to the doctor, I am 76, had a mastectomy in December, 2019. For me, my decision is based on quality of life and not number of years. I wish you well.

I am 74 and just completed 4 weeks on Arimedex (anastrozole) Have no energy, am not sleeping well and have an ache at the base of my neck. Not sure if it's the meds or anger/depression over the current Covid situation. (I realize I have no control over anything other than my own actions, but still, this is NOT the way I envisioned "the golden years") Was hoping by now it would be mostly behind us, and we have had to modify our lives again. I'm in a study at Mayo until the end of August and have a low risk for return of cancer so not sure what I will do when the study is done.

Hi whr, I’ve been on Anastrozole for 22 months and am now experiencing the hip joint pain and back aches. I don’t normally sleep well but I only now sleep 6 hrs very lightly. I’m 68, had my one sided mastectomy in August 2019, started AI September. The thing that bothers me is my oncologist, first appointment said I wouldn’t need radiation. No nodes involved. I didn’t ask about bone density etc then. Now I’m wising up bit after close to two years still no mention of bone building med - but I now am classified as having osteoporosis and STILL no mention of bone neck. Does that sound right. I am going to consult with a different oncologist. Ive learned so much here. Thank you all involved.
