Finishing up my one year of Herceptin

Herceptin has a half life of 20.8 days. This means that half of it is still in your body when its time for the next infusion. This is why you get the large loading dose, so that there is plenty around. So... in another 20.8 days, another half of it is gone and you are down to 25% etc, etc. So, it will take awhile for all of it to be completely gone. I don't have a calculator on me but...

I will say that all of it is not around in 6 months but after 3 months 1/8 is around and in 4 months about 1/18 is around (of the amount of the last dose you got). I think in about 6 months, about 1/70 is still there.

Love, Becky
