Intravenous Immunoglobulin (IVIG) Replacement Therapy
- IVIG is given through a vein by a healthcare professional every 3-4 weeks at a dose determined by the doctor.
- Central catheters are not recommended due to the risk of infections and blood clots. A subcutaneous route can be used instead.
- IVIG can be given in various settings, but self-infusion should be done with a medical professional presence due to the risk of serious side effects.
Subcutaneous Immunoglobulin (SCIG) Replacement Therapy
- SCIG is given under the skin at one or multiple sites, depending on the volume being infused.
- The dose is calculated based on the interval between infusions, and it can be infused daily, weekly, or every two to four weeks.
- Dosage is adjusted to minimize infections, and IgG levels are monitored to correlate with clinical outcomes.
