Immunoglobulins are antibodies made by our immune system that help fight infections.  Patients with immune deficiencies may lack antibodies (immunoglobulins) or the antibodies may not work properly.   Replacement antibodies (immunoglobulins) may need to given intravenously.   These replacement immunoglobulins are collected from thousands of healthy blood donors and consist of sterile solutions of concentrated antibody.  The solutions of immunoglobulins are related to decrease the transmission of known pathogens.

If a patient is started on IVIG, then they come to our office or an infusion center for a 3-4 hour infusion.  The patient is monitored for any side effects during the infusion.   Patients typically receive the infusions every 3-4 weeks.
