Gamunex-C is a medication used to treat certain conditions that affect the immune system. It is an intravenous immunoglobulin (IVIG) preparation that contains antibodies that can help protect the body against infection. Gamunex-C is used to treat a variety of conditions, including primary immunodeficiency (PID), idiopathic thrombocytopenic purpura (ITP), and chronic inflammatory demyelinating polyneuropathy (CIDP). Uses Gamunex-C is used to treat a variety of conditions, including: 1. Primary immunodeficiency (PID): This is a group of conditions that prevent the body from producing enough antibodies to fight off infections. Gamunex-C is used to replace the missing antibodies and boost the immune system. 2. Idiopathic thrombocytopenic purpura (ITP): This is a condition where the body destroys its own platelets, resulting in bleeding and bruising. Gamunex-C is used to raise the platelet count and prevent bleeding. 3. Chronic inflammatory demyelinating polyneuropathy (CIDP): This is a condition where the immune system attacks the nerves, resulting in muscle weakness and loss of sensation. Gamunex-C is used to suppress the immune system and reduce inflammation. Dosage The dosage of Gamunex-C will depend on the condition being treated and the individual patient. The medication is given intravenously (IV) and must be administered by a healthcare professional. The infusion rate and dose will be determined by the doctor based on the patient's weight, response to treatment, and any other medical conditions.
