I also was recently diagnosed with inflammatory NSIP with underlying autoimmune issue recently confirmed. I started on 60mg of prednisone which quickly led to improvements in 02 levels, but after the autoimmune piece(pl-7 antisynthatase syndrome) was confirmed they asked me to start 500mg of cell crept and taper up to 1000mg daily while I taper down the prednisone. I just took my first dose of cell cept today. I too was a little concerned but I figure the need to keep my ILD from progressing takes priority over the side effects. I’ll try to swing back for a condition update as continue the drug treatment.
