I was diagnosed in 2021, had five months of induction then ASCT in November 2021. Since the ASCT, I have been on maintenance of Velcade for about 4 months, then transitioned to Ninlaro. My immunoglobulin levels have never in all that time gotten back up to a normal range. My oncologist has discouraged me from getting IVIG because I haven't had any infections but part of the reason I haven't had infections is I always wear a mask when around other people and don't go out much. Anyone else have experience with IVIG and under what circumstances did you get it?
