Uses For HyQvia

Immune globulin and recombinant human hyaluronidase injection is used to treat primary immunodeficiency (PI) in adults.

Immune globulin injection belongs to a group of medicines known as immunizing agents. It is used to prevent or treat diseases that occur when your body has a weak immune system. Immune globulin contains antibodies that make your immune system stronger. Hyaluronidase injection is a spreading substance that helps improve uptake of immune globulin into the body.

This medicine is to be given only by or under the supervision of your doctor.
