Changing from Cimzia to Rituximab?

Hi everyone I’m 25 and have had seropositive RA for the last 7 years! I’m in a bit of a situation at the moment where my joints are showing signs of erosion but my rheumatologist appointment has been rescheduled 3 times since June. In January I spoke to my consultant about changing meds and her suggestion was to ritzuximab (but said I wouldnt be able to go back on my current meds if it doesn’t work so I said no and haven’t heard anything since and now I’m having new/more problems) but obviously I haven’t been able to have my appointment to ask for it again. I was just wondering if anyone has any experience with these specific med changes and how it affected them and if it helped at all? Or even if you’re currently on rituximab how you’re feeling?
