Dear all,
This is my first time posting, eventhough I have been reading the posts since early last year. This site is my refuge when I am feeling really down..
I am on 30 minutes Herceptin infusion on every 3 weeks cycle for a year (6 mg/kg dosage). Unfortunately, last week, on my 12th session, the herceptin given was underdose ie only 172 mg.
I am supposed to get 330mg per cycle. I managed to maintain my weight to 55kg each time.:-) or :-)??.
The nurses realised their mistake after finishing the infusion.
My oncologist suggested that I am to be given higher dosage of 488 mg for my next appointment.This is to compensate for low dosage last time.
But he didn't know for sure wether his suggestion is okay or not. When I asked him if that last infusion is good, he appeared to be at a loss.
My next treatment is in the middle of next month, and I am scared of what that bigger dosage might do to me. He cautioned me to be on alert for side effects.
Thank you for any info. I appreciate it.

Cheers,
Hannah
