I am moving this up top, because I am thinking about switching to 3-week dosage and wanted to know if anyone had anything else to input.

I am on a weekly regimen of herceptin during chemo. I have one last chemo tx coming up and after that herceptin will be administered on a 3 wk, triple dosage basis.

I am stage IIIc, have been on herceptin every three weeks for 18 months. I have been NED since my surgery Aug. 2005. I have had few side effects from the herceptin, just some increase in sinus problems, thin hair and nails, and still need an afternoon nap, just like my grandchildren.

I have been on the 3 week dose for a year now. I get a little tired (still can do everything) that afternoon, but really it is a piece of cake. So nice not to have to go in every week!
