What happens when you stop taking anastrozole?

A year ago I had similar circumstances. I took anastrozole for six months prior to surgery in order to shrink the tumors. When I started taking anastrozole, I had overwhelming fatigue from then on. My blood pressure went up, and I experienced insomnia for the first time ever. I stopped anastrozole several weeks before surgery, and within three days I felt great. I had energy and slept really well. I felt better than I had in over six months. I restarted a week after surgery and those side effects came back quickly. It made me question resuming it again. Because my tumors were 97% estr/pro positive, my oncologist strongly recommended it.

If you are experiencing these side effects from stopping them, you need to let your health providers know. You don’t want to go into surgery with these symptoms ongoing. I have found health care providers will do whatever necessary to get you past any problems you are having. Good luck with this and I pray for a positive surgery.

Thank you! I feel better now, but the first week off was weird. Surgery tomorrow.

I have been on anastrozole for 15 yrs and have been recommended to continue for life. I am already 78 and also have osteopenia and arthritis. I read that it might be wise to take a 3 month break but my oncologist has not mentioned this. Feel hot all the time. I guess since I am a 20 yr survival it must be helping so will put up with hot flashes.
