Hizentra (immune globulin) is a sterilized solution made from human plasma. It contains the antibodies to help your body protect itself against infection from various diseases.
Hizentra subcutaneous injection(for injection under the skin) is used to treat primary immunodeficiency diseases. This includes, but is not limited to, the humoral immune defect in congenital agammaglobulinemia, common variable immunodeficiency, X-linked agammaglobulinemia, Wiskott-Aldrich syndrome, and severe combined immunodeficiencies.
Hizentra is also used to treat chronic inflammatory demyelinating polyneuropathy (an autoimmune disorder in which the immune system attacks the nerves, causing muscle weakness and numbness).
Hizentra can cause severe allergic reactions, kidney failure, liver problems, or blood clots. The risk of blood clots is highest in older adults or in people who have had blood clots, heart problems, or blood circulation problems. Blood clots are also more likely during long-term bedrest, while using birth control pills or hormone replacement therapy, or while having a central intravenous (IV) catheter in place.
Stop using Hizentra and call your doctor at once if you have little or no urination, swelling or rapid weight gain, dark urine, yellowing of your skin or eyes, chest pain, trouble breathing, fast heartbeats, numbness or weakness, or swelling and warmth or discoloration in an arm or leg.
Drink plenty of liquids while you are using Hizentra to help improve your blood flow and keep your kidneys working properly.
You should not use Hizentra if you have a condition called hyperprolinemia (high level of a certain amino acid in the blood).
You should not use Hizentra if:
you have had an allergic reaction to an immune globulin or blood product; or
you have immune globulin A (IgA) deficiency with antibody to IgA.
You may not be able to use Hizentra if you have ever had an allergic reaction to polysorbate 80, or if you have a condition called hyperprolinemia (high level of a certain amino acid in the blood).
To make sure Hizentra injection is safe for you, tell your doctor if you have ever had:
heart problems, blood circulation problems, or "thick blood";
a stroke or blood clot;
kidney disease;
diabetes;
if you use estrogens (birth control pills or hormone replacement therapy);
if you have been on long-term bedrest; or
if you have a central intravenous (IV) catheter in place.
You may need a dose adjustment if you are exposed to measles, or if you travel to an area where this disease is common.
Tell your doctor if you are pregnant or breastfeeding.
Hizentra is made from donated human plasma and may contain viruses or other infectious agents. Donated plasma is tested and treated to reduce the risk of contamination, but there is still a small possibility it could transmit disease. Ask your doctor about any possible risk.
