What is Gammaked?

Gammaked is made from Immunoglobulins (IGs), which are antibodies that are naturally made by the body to fight infections. Immune globulin therapy, or intravenous immunoglobulin (IVIG), is a therapy that involves the intravenous administration of immune globulin for the treatment of various infectious conditions in adults and children.


What Is Gammaked?

Gammaked is a sterile, decontaminated, ready-to-use 10% solution of human immunoglobulins. It is extracted from human plasma and comprises antibodies, which help protect us against viral and bacterial infections. 

Gammaked serves as an injectable immunoglobulin (IG), used for treating primary humoral immunodeficiency disorders (PI). In these disorders, patients are deficient in functioning antibodies for fighting infections.

Gammaked is synthesized using plasma that is obtained from FDA-licensed centers in the United States. Before accepting a sample, each donor is adequately screened. In addition, every collected sample is tested to ensure its safety before it is cleared for FDA approval.
