Anyone take Anastrozole every other day?

Posted by kamra @kamra, Dec 5, 2024

I wonder if anyone here takes Anastrozole every other day. If so, does it lessen your side effects? Thank you.

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

It has been almost 4 weeks since I went every other day with anastrozole. It affected my stomach and digestive tract when I started it the first few weeks ( 2 years ago) and experienced that again, but milder with lower dozing. Too early to tell for sure how I feel, but seems to be better with less brain fog and joint discomfort!
My decission may have be easier than for most since I had a score of 10% and 3% with AI. I believe they are doing cliinical trials on lower dosing now.

I'm surprised they're so adamant about not every other day. Considering that this one dose has a 50-hour half life. So you're doubling and tripling up every time you take a pill? Is that why you get sick later rather than at first. I am so tired I can't lift my head off the pillow. I sleep 24/7 almost. I have no energy to walk one small block to the pharmacy. I feel sick all the time. I swear to God this is not living. I do not even want to stay alive like this.

@saraabrooks I am fighting fatigue also,

I am thinking about doing that. These cancer meds are hard on our bones. Logically a dosage every other day makes sense especially since the drug stays our system long enough to allow it to build up. Hmmmmm…. Would be interested in opinions of others on this med.

After 2 + years on anastrozole, I went EOD almost 3 months ago. I suggest we tell our doctors but currently I am changing my oncologist because of an office issue and certainly will discuss with my new physician.

I am trying that starting now. I metabolize meds slowly so this might work for me. I’m sure oncologists would object but it’s my body & my need to live the best I can. Sometimes the patient has to strap up!

I've posted this before in more detail. Summary: yes, you can reduce AI dosing to every other day, and yes, your blood estrogen will stay low. But, there is no research on whether the lower dose is as effective at preventing recurrence as daily dosing. In other words, you're in unknown territory if you reduce your dose. I apologize in advance if this sounds negative--and of course, wish you the best.

Yes, when I first posted in January I mentioned that Anastrozole articles say it has a 50 hours half life. For me, I was fortunate to catch it early and my risk of return is low.
If my risk was higher I may have a different view entirely.

@lizr5678 can you share what score you are referring to when you day my score was 10% and 3% on AI?
