About PI
Primary immunodeficiency, or PI, is a disorder that affects the immune system.
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 treatment team will administer PANZYGA through an infusion in a vein, which can occur in a hospital, an infusion clinic, or at home.

- Approximately 50% of all patients missed at least 1 day of work or school due to infections, with an average of fewer than 4 days per person per year
- Hospitalizations due to infections
- 1 adult patient was hospitalized for 4 days due to an infection
