The immune globulin component is prepared from large pools of human plasma consisting of ≥98% IgG. It is comprised of a broad spectrum of antibodies and provides the therapeutic effect. The recombinant human hyaluronidase component enhances dispersion and absorption of the immune globulin infusion.

Hyqvia is available as a dual vial unit of 2 single-use vials containing the active IG 10% and recombinant human hyaluronidase: 2.5g/200 Units, 5g/400 Units, 10g/800 Units, 20g/1600 Units, and 30g/2400 Units. Shipments of Hyqvia have begun.
