Panzyga is used to treat primary humoral immunodeficiency, chronic immune thrombocytopenic purpura (ITP), and chronic inflammatory demyelinating polyneuropathy (CIDP). It provides antibody replacement therapy for patients whose immune systems cannot produce adequate defenses.
Panzyga contains immunoglobulin G (IgG) antibodies collected from donated human plasma. These antibodies help restore deficient antibody levels and modulate immune function to help the body fight infections and manage autoimmune conditions.
Panzyga is administered intravenously by a healthcare professional. Common side effects may include headache, nausea, and fever. Patients should be monitored during infusion for allergic reactions. It is contraindicated in patients with known hypersensitivity to human immunoglobulin or those with IgA deficiency with anti-IgA antibodies.
