Varizig

Product Details

Varizig is the brand name for varicella zoster immune globulin. It’s FDA-approved to lessen the severity of chickenpox in adults and children who are at risk for serious illness. Varizig isn’t a vaccine. Instead, it contains antibodies that fight against the varicella zoster virus, which causes chickenpox. Varizig is given as an injection into the muscle of the shoulder or upper thigh by a healthcare provider. It works best if it’s given within 4 days of exposure to chickenpox. Common side effects include pain at the injection site and headache.

VARIZIG [Varicella Zoster Immune Globulin (Human)] is a solvent/detergent-treated sterile liquid preparation of purified human immune globulin G (IgG) containing antibodies to varicella zoster virus (anti-VZV). VZV is the causative agent of chickenpox. VARIZIG is prepared from plasma donated by healthy, screened donors with high titers of antibodies to VZV, which is purified by an anion-exchange column chromatography manufacturing method. This donor selection process includes donors with high anti-VZV titers due to recent natural infection by VZV, or due to recurrent zoster infection (shingles).
