Your immunology team will give you the information to help you decide which treatment you will have. You might want to consider the following factors:

  • If you have really ‘bad’ veins, then IVIG is not be your best option
  • If you want to take ownership of your illness, then SCIG may be the best choice because you will probably learn how to have home therapy faster.
  • Infusion-related side-effects are more common with IVIG than SCIG and can be related to the volume and rate of infusion.

Your immunology centre will be able to offer you either treatment depending on these factors and your personal choice. Across the UK about 30-40 per cent of people with immune deficiency are on IVIG.
