Concerned about the side effects of anastrozole

Posted by tinalove @tinalove, Jan 31, 2016

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?

I took that drug, it made my knees and joints hurt so bad that I could not walk, I had to change drugs, I am now on Letrolzole, it has side effects too but so far nothing like the anastrozole. I lost my hair, it's not coming back very well, my last treatment was in April 2015.

A number of people have mentioned biotin, also known as vitamin B7, to help promote hair growth. Recently, I came across these articles:
- Biotin, marketed for hair and nails, could skew some medical test results, researchers warn https://www.cbc.ca/news/health/biotin-can-interfere-with-lab-tests-study-says-1.5051992
- The FDA Warns that Biotin May Interfere with Lab Tests: FDA Safety Communication https://www.fda.gov/medicaldevices/safety/alertsandnotices/ucm586505.htm

Here are some key points from the first article:
"It is known that biotin supplements can interfere with lab tests, resulting in false positive and false negative results on a wide range of clinically important tests."
"Health agencies, including the U.S. National Institutes of Health (https://ods.od.nih.gov/factsheets/Biotin-Consumer/), say there isn't enough evidence to support the claims that biotin improves hair, nails and skin, and that more research is required before it should be recommended for that purpose."

@elizm, did your doctor tell you about biotin possibly interfering with lab tests?

Unfortunately, my oncologist did not warn me. I had gone to a neurologist for my CIPN who wanted to do a raft of tests to see if something else might be contributing to the neuropathy. One was for a thyroid test which came back as hyperthyroid. I marched off to my GP who referred me to an endocrinologist and for a thyroid ultrasound. Both doctors knew how much biotin I was taking.

I personally was unconvinced that I was hyperthyroid and started researching the condition online. That is where I found that, up until something like 2016, endocrinologists had been treating patients for hyperthyroidism when in fact it was biotin which was changing the test assay. Sooo, I passed along the news to my GP who allowed me to drop the biotin for a week and then re-take the thyroid test which subsequently was quite normal.

The lessen taught me to stop all supplements about 48 hours or so before every blood test in order to get a more accurate reading on my health. Regrettably, doctors in my area don't instruct patients accordingly.

For hair thinning - my doctor said to use Rogaine shampoo if it bothered me.

Yes, I think it has been helpful for both my hair and nails (all grew back, thick and glossy) and I haven't noticed much thinning in the meantime. AIs are hard on skin, however, and I haven't found something to help that, yet.

My doctor told me to try the Gold Bond lotions - they have some for extreme dryness.

I have been on Femura for 5 weeks and have not seen any hair thinning yet, but perhaps its too early. I did not have chemo, only surgery and radiation.

Was the biotin helpful?
