Dosing
Common Variable Immunodeficiency, X-linked agammaglobulinemia, Congenital agammaglobulinemia, Wiskott-Aldrich Syndrome, Severe Combined Immunodeficiency Individualized SC infusion administered daily to every 2 weeks; patients switching from IGIV begin 1 week after last IGIV dose with initial weekly dose (g) = previous IGIV dose (g) x 1.30 divided by weeks between IGIV doses; patients switching from IGSC use the same weekly dose; monitor serum IgG trough levels to guide adjustments.
Primary Immunodeficiency (IV) 300-600 mg/kg every 3-4 weeks by IV infusion; start at 0.5 mL/kg/hr, increase every 30 minutes if tolerated up to 5 mL/kg/hr.
Primary Immunodeficiency (SC) Initial dose 1.37 x previous IV dose divided by weeks between IV doses, given weekly; 20-30 mL/site at 20-30 mL/hr/site (>=40 kg) or 20 mL/site at 15-20 mL/hr/site (<40 kg).
Multifocal Motor Neuropathy 0.5-2.4 g/kg/month by IV infusion; start at 0.5 mL/kg/hr, may increase if tolerated up to 5.4 mL/kg/hr.
Chronic Inflammatory Demyelinating Polyneuropathy Induction 2 g/kg divided over 2-5 consecutive days, then maintenance 1 g/kg divided over 1-4 consecutive days every 3 weeks by IV infusion; start at 0.5 mL/kg/hr, may increase if tolerated up to 5.4 mL/kg/hr.

Pharmacology
CUVITRU is a human IgG replacement product that supplies a broad spectrum of opsonizing and neutralizing IgG antibodies against bacterial and viral agents, restoring abnormally low IgG levels to the normal range in patients with primary humoral immunodeficiency.
GAMMAGARD LIQUID supplies a broad spectrum of opsonizing and neutralizing IgG antibodies against bacterial and viral agents and contains antibodies that interact with immune system cells; the mechanism in CIDP may include immunomodulatory effects.
