Concerned about the side effects of anastrozole
I completed all treatments for breast cancer but now I am supposed to take hormone blocker, named anastrozole. im concerned about the side effects. Has anyone here taken it and did anyone have hair loss?

- Low-Dose Tamoxifen May Be an Option to Reduce Risk of Recurrence, Invasive Disease After Non-Invasive Breast Cancer https://www.breastcancer.org/research-news/low-dose-tamoxifen-after-non-invasive-dx
Not sure what kind of breast cancer you have but if you have DCIS low dose tamoxifen may be an option. I am unable to post the link to breastcancer.org that has information on this.
Absolutely right! Thank you for your comment. It summarizes my questions perfectly. I’m going to keep asking questions. Like you said, I don’t believe I EVEN have a baseline. You would think that if they know the cancer was estrogen positive, they would be check my ‘levels’. 🤷♀️
The higher dose definitely lowered my estrogen after 8 weeks. It was 10mg. I had more hot flashes and initially, poor sleep. And about 4 weeks in, I started losing my hair (maybe 5-10 strands a day, but definitely more than usual.) Now I am on Letrozole, since end Dec. Hair loss has continued, but I am sleeping and hot flashes are less.
Any chance your oncologist is Dr G at Mayo? Your process is so similar to mine and he is good at getting people on the study.
When I asked about estrogen hormonal levels I got the answer they really do not know what levels mean. If they were going to do levels they should have done a baseline before starting the drug. My frustration with A1 drugs is not only do they have significant side effects but despite thousands of women who are on these drugs they seem unable to state which women are at risk for side effects. Is it age, is it type of breast cancer, is it BMI, is it women who still have their ovaries. I am glad to see that someone is looking at dosage of these drugs because the concept of one size dose fits all seems not very scientific. Can you have the same efficacy at lower doses. Would lower doses mean lower side effects. The fact that 30-40% of women quit this therapy because of side effects is mind boggling. I have this feeling that all they want to do is treat side effects with other meds that have side effects instead of really looking at who is at risk and how to improve this therapy
Thank you jejones. Blood test scheduled for June 24
How did you do on the higher dose of Anastrozole?
That study will have them checking your estrogen levels more often. I was on a study last year. I hope that the 1 mg pill will reduce your estrogen level low enough. It does for most people (but not for me, so I had to go on the heavier dose of Anastrozole !!! ) All the best!!
It was a blood draw for me that told the oncologist that my estrogen was low enough. But it is frustrating when they can't tell you the exact number you have ..and what is acceptable. Keep pushing!!!!
Cindyb, Excellent post. I have been on Anastrozole for 21 months and am now having side effects. When questioning my oncologist in regards to how do they know it is working for me, he said he "takes it for granted" what?! When asked about estrogen test to see what anastrozole was doing and level of my estrogen, he said he didn't know if there was a test for that. I'm reading here that some of y'all have been tested and got results. What test did you have done, just a hormone test, estrogen and progesterone?? I am the point that I may look for another oncologist as my present one is just prescribing what is 'Protocol" and he is not looking at me at a human. I told him I did not want to be a lab rat and he got a little put off, Oh well.
