Good morning all,

I'm getting my last treatment on Wednesday and wondering how long does the drug stay in your system?  My doctor told me I still have to get blood tests till its all out...

Have a good day

    My last herceptin was Dec 08 and my oncologist told me that it would stay in my system for up to 3 months, although he didn't continue to do blood tests after my final dose in Dec.  I kinda took comfort in the thought that it was still in my body for so long, although I guess it's all out now as I'm 4 months out of treatment!
