Common Variable Immunodeficiency Support Group
Common variable immunodeficiency (CVID) is a group of 20-30 primary immunodeficiencies (PIDs) which have a common set of symptoms but with different underlying causes. CVID's underlying causes are different, but the result of these are that the body doesn't produce sufficient antibodies in response to exposure to pathogens.
I have received IVIG Gamunex C 35 mg for about 18 months now. I feel like the dosage would be up to your doctor. How often to you infuse? I am every four weeks but during the fall/winter months when I know I get sick I infuse every three weeks. I noticed that has made a difference. I also take Vitamin D which has helped.
