Herceptin and tamoxifen

[*_Donna_*]

Can you take tamoxifen and herceptin at the same time? Just curious, Thanks ! God Bless

My Dr. said no, and also no to taking it while on radiation. As soon as I am done with rads will start tamoxifen. Was told there is not enough info on combining tamoxifen with chemo and rads concurrently.

Please disregard my earlier post, I misread yours. I will taking tamoxifen along with herceptin when I finish rads. Sorry for the confusion, my brain took a vacation without me!

I am taking tamoxifen and getting "late" herceptin every 3 weeks.

Dear ladies,

There is a trend to concurrent herceptin + hormonal dosing, in fact I just finished reading an article a couple weeks ago stating that if you are ER+ and on herceptin, you should be also taking at least an A.I. Tamoxifen (TAM) + herceptin, there are 3 distinct camps on that one; one says OK and the another 2 say no! Still question if the TAM doesn't cause (1) tumor proliferation or (2)cross-talk between the E and EGF receptors creating TAM resistance.
There is also a thought that if you are HER2 and ER ++, there is a hierarcha relationship between them and tumor growth, where HER2 has by far the greater influence on the tumor.
