I've been on Ixifi for 8 months.
It worked great for the first 2-3 months and then stopped.
All symptoms came back.

Took an antibody test and it came back 85.2 Anti IFX antibodies
.
Googled around but can't seem to find if this is considered high?

Does this mean it's not going to work anymore?

An injectable version of infliximab?

It's Pfizers version of Remicade.
I understand it's a biosimilar.
I go to the infusion center every 8 weeks and get it by drip.

I think that's quite high but check with your doctor. It only worked for me for 9 weeks and then I developed antibodies. Sorry it stopped working for you, too.

I just looked up my results. They were 40 and that was a low antibody response. But I was severely flaring, so we moved onto Humira (which did nothing).
