Hi was told on Friday that I am producing antibodies against Rebif injections, am hoping that I won’t have to come off my medication, has anyone else had this problem? have been on it just under 3 years, am awaiting results of my recent blood test, any advice will be much appreciated. A

I had Tysabri antibodies and had to come off it, I waited 2 months to see if antibodies went but they did not so no more Tysabri.

How it was explained to me is if you develop antibodies to a biological drug then those antibodies take out the drug and that reduces its affectiveness or makes it useless.

It might be different for Rebif but I doubt it. You would be able to have Gilenya and that is chemical based and not biological.
