GAMMAPLEX is an intravenous immunoglobulin (IVIG) therapy used in the treatment of primary immunodeficiency diseases (PIDD) and chronic immune thrombocytopenic purpura (ITP). It is a sterile solution made from human plasma containing antibodies that help protect the body against infection. GAMMAPLEX works by supplying the immune system with the antibodies it needs to fight off bacteria, viruses, and other pathogens, thereby reducing the frequency of infections in individuals with weakened immune systems. It is administered under the guidance of a healthcare professional and the dosage depends on the condition being treated and the patient's body weight. As with any blood product, there are potential risks and side effects, but GAMMAPLEX is carefully screened and processed to ensure safety and efficacy for patients requiring immune system support.
