I started rituximab today. How long before I would know if the circulatory B cells have been reduced and by how much?
Your CD19 and CD20 B cell count will be reduced very rapidly after rituximab treatment, but it will not be necessary to recheck your B cell counts for at least 3 to 6 months depending on the dose that you received. Your doctor will explain this to you.
