Rozv, your experiences on Anastrozole mirror my own. I also tried Tamoxifen, and can attest that it is easier to tolerate than Anastrozole, but when I was told I HAD to step up my intake from 10 mg. to 20. mg., things went South for me. I was on 10 mg. from April 23, 2023 until June 23, 2023. I had told my Texas oncologist that I was only going to take 10 mg. (not 20) and the reason was the Italian Women's Study of 700 Italian women who took a reduced dosage. I actually was only taking the 10 mg. every other day, so my total weekly consumption was 40 mg. On this dosage I experienced dryness and a constant urge to urinate. Nothing felt normal from the waist down, but I did not have the extreme fatigue or the UTIs that I experienced once I moved up from the 40 mg. a week to 140 a week. I was told by my Texas doctor's office that my faith in the Italian Women's Study was misplaced, because I was comparing apples to oranges in that their tumors were "in situ" and mine had broken through. Therefore, I agreed to step up to 20 mg. daily and that was NOT a good idea for me. I immediately had EXTREME fatigue. I could only be up for 3 hours at a stretch. I began having what felt like UTI infections and they were not able to be quelled by Amoxicillin or another strong drug prescribed by my physician. (I also tried something OTC that did nothing but turn my pee orange). This started before New Year's Eve and, after 10 days of this constant burning and itching and urinating I was headed to the convenient care when it dawned on me that I should probably call, instead, the OB/GYN my oncologist had made me get an appointment with, to keep tabs on the possibility of a thickening of the uterus (uterine cancer symptom) from Tamoxifen. I had been on her appointment calendar for 9 months. She refused to see me and I was reduced to tears, while driving to the convenient care facility. Her scheduling person called me back and told me to call my oncologist, which I did. He had me drive to another town and leave a urine specimen and that was when and how I got the second strong antibiotic. The 2 strong antibiotics then turned into a fungal infection, which also required medication and an office visit. I quit taking everything on Aug. 30, 2023. Am I concerned that I might have a recurrence since my onco score was 29. Of course, but I can't say that having non-stop UTI infections is a good trade-off, since I have a good friend who died from one that went septic. (As did the former Charlie's Angels star who died at 65 from one.https://www.womenshealthmag.com/health/a35155137/actress-tanya-roberts-death-urinary-tract-infection/).

So, my choices are: to take Anastrozole and be wheelchair bound and suffer agonizing joint pain OR risk endometrial cancer or a blood clot or sepsis, as described above.

When you need "protection" from the "protection" it is time to take stock and analyze the risks versus the benefits, which is what I have done at the ripe old age of 78.
