Generic name: Immune Globulin

Usage of Panzyga (Immune globulin Intramuscular, Intravenous, Subcutaneous)

Immune globulin injection is used to prevent infections or make the infection less severe (eg, hepatitis A with not more than 2 weeks of exposure, chickenpox, measles with not more than 6 days of exposure, has not been vaccinated, and has not had measles previously, or rubElla) when your body has a weak immune system. Immune globulin contains antibodies that make your immune system stronger. It is used for patients who have primary humoral immunodeficiency (PI), idiopathic thrombocytopenic purpura (ITP), chronic immune thrombocytopenic purpura, chronic inflammatory demyelinating polyneuropathy (CIDP), or dermatomyositis (DM).

Immune globulin injection is used to treat primary humoral immunodeficiency (PI), idiopathic thrombocytopenic purpura (ITP), and chronic immune thrombocytopenic purpura in children. Safety and efficacy have not been established for use in chronic inflammatory demyelinating polyneuropathy (CIDP), multifocal motor neuropathy (MMN), or dermatomyositis (DM).

    Appropriate studies have not been performed on the relationship of age to the effects of Gamastan® in the pediatric population. Safety and efficacy have not been established.

    Geriatric

    Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of immune globulin injection in the elderly. However, elderly patients are more likely to have age-related blood clotting problems, kidney disease, or heart disease, which may require caution for patients receiving immune globulin injection.

    This medicine is made from donated human blood. Some human blood products have transmitted certain viruses to people who have received them, although the risk is low. Human donors and donated blood are both tested for viruses to keep the transmission risk low. Talk with your doctor if you have concerns about this risk.

    This medicine may cause a serious type of allergic reaction, including anaphylaxis, which can be life-threatening and requires immediate medical attention. Tell your doctor right away if you have a rash, itching, hives, chest pain, dizziness or lightheadedness, trouble breathing, trouble swallowing, or any swelling of your hands, face, or mouth after receiving this medicine. Certain people, including those with IgA (an immunoglobulin) deficiency and antibodies against IgA and a history of hypersensitivity to human immunoglobulin products should not use this medicine.

    Check with your doctor right away if you start to have a stiff neck, drowsiness, fever, severe headache, nausea, vomiting, painful eye movements, or eye sensitivity to light. These could be symptoms of a serious condition called aseptic meningitis syndrome (AMS).

These may be symptoms of a serious lung problem, including transfusion-related acute lung injury (TRALI).

    This medicine may cause blood clots. This is more likely to occur if you have a history of blood clotting problems, heart disease, or atherosclerosis (hardening of the arteries), or if you are obese, take medicines containing estrogen, or must stay in bed for a long time because of surgery or illness.
