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?

Interested in more discussions like this? Go to the Breast Cancer Support Group.

Take the anastrozole at night to avoid sleepiness. I too felt very tired about 6-7 hours after taking it in the morning. I now take the medication around 7 each evening. Feeling much more awake during the day.

Thankyou I’ll try taking that night.
In fact my Dr also suggested I try taking it at night. I’ll let you know the results.
All the best

I hit my 5 year & my doctor refused me the BCI test - which I thought was really unfair. She wanted me to commit to another 5 years - which I refused, so she said the BCI test was not needed. Made me angry - why do doctors do that? She also said another 5 years would only reduce the risk of reoccurrence by less than 3%.

@kathyomaha55 after 5 years , I’m assuming with this dr. I would think they’d be more compassion. What was the reasoning for her to recommend another 5 yrs? I find it interesting that a Dr recommends a continuous of medication for 5 yrs But refuses a test that would give information If continuing would be of benefit. That does not make any sense to me. Well if this BCI testing is important to you, as it will give you more information, you should follow up with the facilities management or if she is private practice have you primary care order it. Be proactive for your Health and well being. Good luck & Blessings.

The BCI test did not apply to my case as I had 7 positive lymph nodes with extra nodal extension of nodes. That is the reasoning for AI 10 years. Anastrozole does cause some insomnia and joint aches but I am managing them most of the time. What I think is most important for all of us is that we find a physician we feel is a good fit and can communicate and educate .what we need personally. I’m also taking verzenio-that’s another story-so difficult to tell which med causes which side effects. I admire every breast cancer warrior, while we all have/had this unwanted change in our lives we are so open to help our new sisters and their families.

I started it on Thanksgiving evening. My main problem is joint aches. I feel like an old lady when I’m trying to get up from a chair, my hips, my back my shoulders and now my thumb I am more tired than I’ve ever been. I take an afternoon nap. I am going to try it for six months and then reevaluate. . Hope that helps.

It is 6 months now that I’m on anastrozole(Armidex). I take it around 8am, and by 3-4pm I feel so sleepy and fatigued. It seems this side effect seems to kick in with 7to 8 hours after I take the tablet. My hair has started to also thin quite rapidly. I have started having acupuncture treatment which hopefully will improve my energy level.

I take mine between eight and nine in the evening that way I feel like I am sleeping through the worst of it. By 2 to 3 PM in the afternoon to take a short nap.

@mossa my cancer was 95% estrogen positive and 85% progesterone positive but the Breast Cancer Index still told me there was no benefit to extending treatment past 5 years. I had to get the paperwork for the test myself but most doctors will do it if they see it in the NCCN guidelines. The Oncotype showed risk reduced 50% but BCI was the only thing I could rely on at the 5 year point.

I am wondering where you heard that taking anastrozole at night can make you sleepy. I have trouble falling asleep (but there has been a lot of stress in my life lately). My oncologist didn't give me an answer on when is the best time to take it. Thanks1

I had terrible insomnia on this drug as well as on exemestane. It never made me sleepy. I tried CALM for sleep - gummies. Took 2 before bed time & it helped a lot.

I started it in October at age 52. Stage 1A IDC hormone positive. No chemo. 15 days of radiation.

The biggest side effect for me is joint pain when I’ve been seated for a long time or waking up in the morning.

It dissipates with movement. My sister started taking it too. Prescribed preventatively by her dr bc her risk of developing bc is high.

The best advice is taking it at night. It can make you tired. It’s worth trying it for me because of the reduction in recurrence that it brings.

Best to all!
