I have heard of people doing two DMD's. I have also heard of double dosage of Betaseron (but that was in a trial).
I'm a bit surprised he would suggest perhaps "adding" Copaxone, when he isn't even sure if your antibody test for Rebif alone might not be ok.

I don't think Copaxone would add to the antibody problem, but I don't think I'd add another heavy-duty drug when you are already having problems with one of them.
I don't think I've heard of Copaxone and any of the interferons together either, I think it was Rebif or Avonex with Betaseron.
Betaseron is different from Avonex and Rebif (which are the same type of interferon, but a difference dosage). Copaxone is not a interferon, and I have always understood it to modulate in an "enhancing" manner vs. the interferons modulating in a "suppressive" manner.
Are you RRMS? How long have you been dx?
