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 care team will administer PANZYGA through an infusion in a vein, which can occur in a hospital, an infusion clinic, or at home.
Steps to help prevent infections

PANZYGA PI treatment benefits
Back to topIn a clinical study, PANZYGA helped prevent patients with PI from getting serious bacterial infections (SBIs).
- Days missed from work or school
- 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
PANZYGA PI side effects
Back to topAdverse events reported in >5% of the 51 patients with PI treated with PANZYGA in a study.
The most common side effects of PANZYGA in the PI clinical study were headache, abdominal pain, fever, nausea, sinusitis, fatigue, and bronchitis. Allergic reactions may occur.
