Ibrance schedule

[Greatday2]

Do any of you take longer than 1 week off? Like maybe take 9-10 days off? I would really like to do this once in a while because I think it would help my blood cells to recover more. My doctor isn't really in favor of this but I was just wondering if any of you do this on your own.

My NP, with permission from my oncologist, put me on a 3 week on and 3 week off routine of Ibrance.

My WBC’s take 3 weeks to come back to normal before starting a new cycle. I’ve been on this schedule for the last 3+ years and my regular CT scans show stable each 3 months.

I’ve been on Ibrance 100mg since October, 2019, having dropped from 125mg when WBC’s dangerously low.

I hope this helps and I wish you all the best on your treatment. Hugs, KS

Thanks for your reply. That sounds like a great schedule. I would love to be on that schedule! My numbers aren't super low, they just don't come back up to normal ever. My oncologist isn't concerned - I just would like to see my numbers hit near normal once in a while.

With my oncologist's support, I take ribociclib on my own schedule which is weekdays on, weekends off. This schedule keeps my cancer antigens in the normal range so they are not growing ( I have breast cancer in many sites).

Most importantly, my leukocycte count stays well above the very low level (below 1) where it was on a three weeks on, one week off schedule. It is still not in the normal range (it's currently 2.7, not the Canadian standard of 4.1+) but at least I have some protection from infection.

Please note that weekends off mean I take ribociclib (with letrozole) on 20 days every 28 days. On a three weeks on, one week off schedule, I would be taking meds on 21 days every 28 days. We're really only talking about 1/28th less!

Thanks for sharing. My numbers have never been extremely low; but they just always stay low, no matter where I am in the cycle. My oncologist isn't concerned about it. I just want my numbers higher once in a while!

Any progression on this schedule

[Hazelgreen in reply to Praising]

None, so far. It's now been more than two years that I've followed this schedule. At 79 years of age, I don't want to get sick again.

I am currently on a three week on two week off schedule, 125 mg dose. I never totally recover to a normal wbc and anc, but it has been stable for a few years now, no low dips. My oncologist is very by the book and generally follows what is recommended. After two or three times that I had to wait another week this became my schedule. Pfizer has recommendations about when Ibrance should be held according to neutrophil levels. Maybe you can use these to discuss with your oncologist.

Thanks for your reply. My levels have never been super low. But they don't ever seem to be anywhere near the normal level. They just seem to stay low no matter where I am in the cycle. That's why I wanted to give it a little more time to see if they would come up more. Thanks again! How long have you been on Ibrance?

4 year anniversary coming up this month. I’ve thought about taking a break at times but figured it would show up on bloodwork and I would have to fess up!

[Rotagirl]

I regularly take 8 days off as I know 7 days is not enough to get neutrophils up to 1.00. I have been on this combo (palbo and letrozole) for 6 years and am on 75mg. Hope that is some help. I have not told my oncologist I am doing this !

[Greatday2 in reply to Rotagirl]

lol that's what I am thinking of doing! Thanks for sharing.

[Praising in reply to Greatday2]

Me too. But she has me come back for blood draw to make sure it’s over 1. Ugh

[Praising]

guess I could stop pill earlier

I took an extra week at one point, but it was recommended by my oncologist/
