Dosing

Primary immune deficiency disorder IV: 300-600 mg/kg every 3-4 weeks; SC (PI only): individualized weekly dose calculated as previous IGIV dose (g) x 1.37 divided by number of weeks between IV doses.

Immune thrombocytopenic purpura IV only: total dose 2 g/kg given as 1 g/kg on two consecutive days or 0.4 g/kg on five consecutive days; do not administer subcutaneously.

Polyradiculoneuropathy, Chronic Inflammatory Demyelinating IV only: loading dose 2 g/kg over two to four consecutive days; maintenance 1 g/kg every 3 weeks (or 0.5 g/kg on two consecutive days every 3 weeks).

All indications Initial dose 5-60 mg once daily with food; RAYOS releases active substance approximately 4 hours after intake. Titrate to lowest effective maintenance dose; withdraw gradually after long-term or high-dose therapy.

Contraindications

Previous anaphylactic or severe systemic reaction to human immune globulin
IgA deficiency with antibodies against IgA and history of hypersensitivity reaction

Pharmacology

GAMMAKED is an immune globulin that supplies a broad spectrum of opsonic and neutralizing IgG antibodies against bacterial, viral, parasitic, and mycoplasmal agents and their toxins; the precise mechanism of action in ITP and CIDP has not been fully elucidated.

Prednisone is a synthetic corticosteroid with potent anti-inflammatory and immunosuppressive properties that suppresses inflammatory processes (edema, capillary dilatation, leukocyte migration), modifies immune responses, and produces metabolic effects including promotion of gluconeogenesis, protein catabolism, and altered calcium and electrolyte balance.
