I am not familiar with the use of Rituxin in detail for CIDP, and have NOT (edited) taken it, so I wouldn’t be a good person to comment on that. Sounds like your dr doesn’t think that was the cause though, as they increased IVIG rather giving Rituxin again. You might want to ask your dr his/her thoughts on that.
You’re welcome! Glad it could help as that abbreviation is seen a lot here.
