What is the usual anastrozole dose for women?
For women, the standard oral dose of anastrozole used for hormone-receptor positive breast cancer is 1 mg by mouth once daily. [1]
How is anastrozole taken (timing, with/without food)?
Anastrozole tablets are taken by mouth, once each day, at the same general time. Food does not change how the medicine is absorbed in a way that requires dose adjustments, so it can be taken with or without food. [1]
Who gets anastrozole, and does that change the dose?
Anastrozole is used in postmenopausal women for breast cancer that is estrogen receptor–positive (or hormone receptor–positive). The dosing regimen described above applies in those typical clinical uses. If a clinician is using it for a specific indication, they may still keep the daily 1 mg dose but will base the overall plan on the individual’s treatment context. [1]
What if a dose is missed?
If a woman misses a dose, she should take it when she remembers unless it is close to the time for the next dose. She should not take two doses at once. [1]
Are there dose adjustments for kidney or liver problems?
Some drug labels and clinical resources note the need to consider kidney or liver impairment when using anastrozole, but the commonly listed starting dose remains 1 mg once daily. A clinician should confirm the right plan for someone with significant liver or kidney disease. [1]
