The product is a combination of human immune globulin
and recombinant human hyaluronidase.
For example, in a comparison of the activity of human MAbs with that of human immune globulin
, 0.7 mg of a mixture of two MAbs had the same neutralizing activity as 100 mg-170 mg of tetanus immune globulin (90).
"Dear Healthcare Provider" letters, issued by both organizations, advised caution when prescribing and infusing intravenous human immune globulin
(IVIg) to patients with cardiovascular disease or previous thrombotic events.
The investigational VariZIG, similar to licensed VZIG, is a purified human immune globulin
preparation made from plasma containing high levels of anti-varicella antibodies (immunoglobulin class G [IgG]).
Contraindications for VariZIG administration include a history of anaphylactic or severe systemic reactions to human immune globulins
and IgA-deficient patients with antibodies against IgA and a history of hypersensitivity (2).
