Tamoxifen and anastrozole
Hi all,
I have a question about these AI. I'm pretty much at the beginning of this journey, just had a lumpectomy and now waiting to start radiation. My oncologist said that I will go on a AI but did not specify which one yet. I know most of you ladies are on or have been on them so I would like to know , did they change you mentally and how did you cope with them ? I already know that they will physically 😒 I believe he wants to do this because my mother and 2 sisters had breast cancer and past away.
I lead a pretty active life at the age of 67, gardening, canning, chickens and several hobbies. I know this is long winded but this really concerns me and thinking of refusing them. Your input would be greatly appreciated .

Hi again, two of the brand names that I buy; knudson and ocean spray tart cherry juice.
I hope it helps. Take care
Your pharmacy will be able to tell you the manufacturer. It may also be in small print on the bottle. I was prescribed xanax for anxiety and sleep when I was first diagnosed. The first bottle I had no side effects. The second script from a different pharmacy smelled like strong chemicals and caused facial hives. It was the same manufacturer. Of course the pharmacy said the pills were the same but I knew something had changed. My Dr called in a script to a different pharmacy and the manufacturer was different. No more smell nor hives. I did read in one of my groups that different manufacturers use different fillers and the different fillers can cause side effects. You can also call the manufacturer to see if they changed the formula. I'll see if I can find the post. I hope this helps.
AI's from different manufacturers were a big issue for me in terms of tolerability. I took brand name Femara (letrozole) though at the end I did find a generic I could tolerate.
Hi @nanna1948, I was intrigued by your statement and went on the search for a source confirming the claim about anastrozole's (Arimidex) ability to continue to protect against recurrence after completing 5 years of treatment.
I think this may be where you read it.
- What happens when you stop taking Arimidex? https://www.drugs.com/medical-answers/you-stop-taking-arimidex-3539770/
Excerpt:
"The protective effects of Arimidex continue even after you stop taking it, so long as you have been taking it for around five years.
The latest results from the IBIS-II prevention trial reports Arimidex continues to significantly reduce the incidence of breast cancer for at least 5.9 years (the current duration of the trial). The trial is ongoing."

Hi
I have dcis it was stage 0 when they did the pathology there was a slight break in one of the walls so it went to a stage 2 but a microscopic amount of invasive cancer no cancer in my lymph nodes just did 10 days of radiation double hits so now I will follow up with my oncologist regarding the AI I just would like to know if you have osteopenia or osteoporosis prior to your breast cancer treatment my initial conversation with my oncologist because I have a compression fracture in my spine and I have osteopenia which I have been treated with zoldronic acid for the last 2 years I have my third infusion this year in June. I know that the AIS can cause bone loss and tamoxifen was the medication he discussed me trying I am 65 I'm just so unsure about what medication to go on. Plus I'm hypersensitive to meds and have fibromyalgia.
Hi
Thank you for all the information on that medication I am 65 with osteopenia and a fracture in my spine t7 just finished my treatment for dcis after having two surgeries her two negative er pr positive. 10 dbl radiation treatments. My oncologist wants me to try 5 mg of tamoxifen so I think I'm going to give that one a try I will find out when I see him this coming Thursday April 4th
Hi! @nana49 :
Thank you so much for your caring kindness! I'll definitely look for it more carefully and try taking it with Anastrozole:)
Best wishes to you all on journey ahead!
Hi sue417--my bone density was just fine going in, and I intend to start having it checked. You might ask your oncologist to explain how much tamoxifen will reduce the risk or recurrence, and if it extends life expectancy. This really can vary case by case. I have fibromyalgia-like chronic pain. Keeping this under control is probably my highest priority. I've had no ill effect from letrozole, but ave never been on tamoxifen. Check in and tell us what you decide to do and how it is going. It's hard to juggle all this--but I tell myself so far so good!
@sue14 I had had osteopororis for several years and had three spinal fractures when I went on letrozole for cancer. Most people do Reclast or Zometa (zoledronic acid) with aromatase inhibitors but my doctors were nervous about it for me because at the time it was thought to aggravate atrial fibrillation, which I have on occasion. That has since been debunked, according to my doctor. Anyway I had bone loss, had more fractures, and went on Tymlos after my cancer treatment. Tymlos returned my bone density to pre-cancer levels- actually a little better.
I am not sure what others' experiences are with aromatase inhibitors that are accompanied by zoledronic acid. I hope someone else chimes in! It does seem that many do tamoxifen if they have bone density issues, and I am not sure why that was not offered to me. It is good to discuss these options with your doctor!
Hi
I also have fibromyalgia plus a heart condition and I had a Tia 5 yrs ago. My oncologist said 5mg tamoxifen that was prior to my surgeries so I will see if that changes thks
