KIOVIG is a brand name for a medication known as Immune Globulin Intravenous (Human), which is used in the treatment and management of various immune system disorders. It is a highly purified form of human antibodies, collected from the plasma of thousands of donors, and is designed to boost the immune system in patients who have a deficiency or are unable to produce sufficient antibodies on their own. KIOVIG is commonly prescribed for conditions such as primary immunodeficiency diseases, where the body's natural defense system is significantly weakened, and for certain autoimmune disorders. It is administered intravenously, allowing the antibodies to quickly integrate into the patient's bloodstream and provide the necessary immune support. KIOVIG's effectiveness, combined with its safety profile, makes it a critical component in the management of these complex conditions, helping to prevent infections and improve the quality of life for affected individuals.
