Subcutaneous immunoglobulin (SubQ) therapy contains antibodies collected from the plasma of healthy donors.
How is SubQ1 administered?
SubQ is given subcutaneously, which means under the skin. You can administer SubQ at home using a small portable pump and small needles. A typical infusion takes 1-2 hours.
Proper self-infusion techniques are important and are typically taught by a nursing professional at your doctor’s office. If your doctor determines that SubQ is right for you, your training will begin with your very first infusion. After an initial period of SubQ training, you will be able to administer your weekly infusion on your own schedule in the comfort of your own home.
How often do you get SubQ1 infusions?
Unlike IVIG, SubQ is infused weekly and in smaller amounts. SubQ replaces antibodies the body should be making, but does not help the patient's own immune system make more, so repeated weekly doses are needed.
Are all SubQ1 therapies the same?
There are some differences in subcutaneous immunoglobulin brand formulas that may make one product more suitable for you than another. Your doctor can help you determine which brand is best for you.
Is SubQ1 more appropriate for some patients?
SubQ might be more appropriate for some patients1:
- Who have smaller veins that are hard to find and access
- Who frequently experience certain uncomfortable side effects associated with IVIG
- Who prefer to have more control over when and where they infuse their IgG therapy
- Who prefer to infuse their IgG therapy in the comfort of their own home
- Who frequently travel and need to take their therapy with them
Your doctor will determine if intravenous infusion is right for you
