there is also at least one retired oncologist who lurks
yes Herceptin can cause low white blood cells
White blood cells (WBC) are important for fighting infection. While receiving treatment, your WBC count can drop, putting you at a higher risk of getting an infection.

it is a monoclonal antibody so that doesnt surprise me at all
I note you are on filgastrim - which I was on as well. I bet your havent gone down to 400, ( yes 0.4 = you cant see any)
it is vital that you dont use our advice to fiddle and fine tune your therapy, but follow the advice of your team treating you. Because the results are always worse.
and you dont have to be a doctor to say that !
Good luck
I imagine there is a cocktail of drugs to choose from that cause low white blood cells - I had vinc, cyclo, pred, gemcitabine, ritux, roob to choose from. dont fiddle with any
