Doctors treat bacterial infections with antibiotics. People who get severe or frequent bacterial infections may need to take antibiotics for several months at a time to prevent them.
If your hypogammaglobulinemia is severe, you may get immune globulin replacement therapy to replace what your body isn’t making. You get this treatment through an IV. The immune globulin comes from the blood plasma of healthy donors.
Some people only need a single injection of immune globulin replacement. Others will need to stay on this treatment for a year or more. Your doctor will do blood tests every few months to check your levels until they get up to normal.
