Biosimilar for Herceptin

[Colleen]

It’s been awhile since I have been on here to post. I am curious if anyone has been switched to a biosimilar for herceptin and if they have had any side affects that they did not have with Genentech’s herceptin.

My wife has been on two herceptin/trastuzumab biosimilar for several years, they seem to be the same.
