Can the patient be maintained on the same dose of IVIG indefinitely?
No, there must be an attempt to wean the initial dosage when improvement has occurred. There must be an attempt to stop the IVIG infusion if improvement is sustained with dosage reduction. If withholding or decreasing IVIG therapy is inappropriate for the purpose of assessing response to therapy, then the record is expected to include documentation discussing why therapy cannot be withheld or decreased. If clinical improvement does not occur with IVIG, then the medication should discontinued.
