The Cellcept is for the RA type pain I have with my Sjogrens officially but I only got it because the rheumy registrar failed to read my neuro' letter telling him I shouldn't be taking these type of drugs! Then it was too late for him to completely backtrack as I'd started so he wrote that it was a four month trial as usually these neuro symptoms in seronegative Sjogrens would only be treated with the Gabapentin family - which I won't touch again! I have already had severe reactions to Methotrexate, Sulfasalazine,Hydroxichloraquine and Azathioprine so no more options will be offered after this he tells me. Unless I start getting organ involvement or Lymphoma in which case I will meet the NHS criteria for Rituximab. Hope this explains!
