I’d have to agree with

Brandy and ask IF you have had IVIG recently…the ‘flu-like’ symptoms it can give you are going to be DEFINITELY flu-like up to a week/10 days later. IF you are ‘flu-ey’ right before you are to have a scheduled infusion, well, let your infusion folks AND your prescribing doc know about it rite away. They mite delay a future infusion until they do the usual tests, such as blood and urine and the like. Or, it could be the introduction of a new medication into your life? Just things to think about. Also, to be super Safe about.
I hope this all is useful, and keep us all up to date on how you are doing!
