What is GAMMAGARD LIQUID?
- GAMMAGARD LIQUID is indicated for the treatment of primary humoral immunodeficiency diseases (PI) in patients two years of age and older. GAMMAGARD LIQUID is a ready-to-use, liquid medicine that contains immunoglobulin G (IgG) antibodies, which protect the body against infection.
- GAMMAGARD LIQUID is made from human plasma that is donated by healthy people and contains antibodies that replace the missing antibodies in patients with PI.
- GAMMAGARD LIQUID is given into a vein (intravenously) or under the skin (subcutaneously). You and your healthcare provider will decide which way is best for you. Most of the time infusions under the skin are given at home by patients or caregivers. Although it is possible to give yourself infusions into a vein at home, they are more often given in a hospital or infusion center by a nurse. Only use GAMMAGARD LIQUID by yourself after you have been instructed by your healthcare provider.
