What is PI?

PI occurs when antibodies that help fight infection are reduced or missing from the immune system. Patients with PI are more likely to get infections.

How PI is treated

PI is typically treated by using intravenous immunoglobulin (IVIg), like PANZYGA, to increase antibodies and help patients with PI fight infection. A nurse or other member of your care team will administer PANZYGA through an infusion in a vein, which can occur in a hospital, an infusion clinic, or at home.
