Timing of HRT, anastrozole - taking day or night?

Posted by trixie1313 @trixie1313, Mar 7, 2019

I've seen many messages about anastrozole, but does anyone prefer to take this in the morning or evening? I'm wondering if side effects are less via day or night?

I have completed chemo for stage 1a breast cancer . Lumpectomy completed 7 mos ago. I completed radiation and am now to begin Anastrozole 1 mg. Curious if less side effects appear in AM or PM?

I found that taking it in the morning was best. It caused me insomnia, so morning was a no brainer for me.

After dinner. Along with other supplements for hair loss (minoxidil) and joint pain (glucosamine). I was already taking calcium for bone loss. At bedtime I take melatonin for hot flashes. The combo is working, thank goodness. 🤞

I started taking it in AM but the hot flashes were horrible all day - did this for almost a year. So at my appt when we talked about side effects I was having - I said I hate them all but right now the hot flashes were the worst - so it was suggested to take it at night (yes night sweats but a tower fan on low helps immensely!! I've been taking it PM for almost 3 years now and it has really helped - I may get an occasional one now and then but nothing like before. So I can check that off the list of side effects I have on anastrozole as it's manageable now.

I take mine in the morning. No side effects other than Osteo decline. I am 2 1/2 years in and I am getting ready to start Prolia injections twice a year for my osteopenia and osteoporosis. I should mention I am very cautious with diet, routinely exercise, and take supplements as needed. I too had lobular breast cancer stage one a and invasive ductal cancer stage one a.

My oncologist prescribed Prolia when I was just starting anastrozole and with only a hint of Osteopenia.

One six month dose was all I could tolerate. The aches and pains were terrible but the mental side effects were too much. Changed oncologists and she agreed I didn’t need it as I wasn’t even on the scale of bone loss.

Please do your own research on Prolia. It isn’t something to introduce in your body without knowing what it can do to you.

Hi @jsparkle42,

I combined your discussion with an existing discussion titled:

Here, members have discussed how they take their anastrozole (am or pm) and how it has worked best for them.
