Neil, I don’t know yet. Just started the Sandoz a few days ago.My post transplant labs are now only every 3 - 6 months. I get them done about a week before an office visit with my provider. My next appointment is in November and I’ll know then. The levels have been really stable and my dose hasn’t changed in a really long time. That has been the goal for nearly 18 years. Thank God it seems to be the case. Have you switched to Sandoz?
