(7/18/19) There have been reports of issues regarding access to immunoglobulin (Ig) therapies. For more information, please visit the Plasma Protein Therapeutics Association website.
(10/24/19) The FDA's Center for Biologics Evaluation and Research has provided a list of resolved CBER-regulated product shortages. CBER-Regulated Products: Resolved Shortages
Please let us know if you are having problems getting immunoglobulin therapies and what the product is (if you know). PDSA will do everything we can to assist you.
Intravenous immunoglobulin (IVIG) is a type of antibody treatment used as a “front line” therapy to temporarily elevate platelet counts.
IVIG is a solution of IgG (immunoglobulin G) antibodies normally present in adult human blood.1 IgG antibodies are extracted from the combined plasma of more than 1,000 screened donors and treated to eliminate bacterial and viral contaminants. It is used to treat immune deficiency and many other conditions on-label and off-label.1
Different companies manufacture IVIG and each brand has slightly different features and side effect profiles. The BDI Pharma IVIg Comparision Chart and the Immune Deficiency Foundation Chart provide more information.
IVIG is given intravenously for a period of several hours. There are two different dosage options: .4 grams (g) / kilograms (kg) per day for five days, or infusions of 1 g/kg per day for one to two days. The higher-dose, shorter-term administration leads to a more rapid rise in platelet count, but higher toxicities.3
The most common side effects of IVIG include: headache, fever, chills, nausea or vomiting, muscle pain or chest pain. Fortunately, slowing down the rate of infusion can help eliminate these problems or decrease their severity. Premedication with acetaminophen, antihistamines or occasionally steroids can also help decrease side effects.4
Patients who are IgA (immunoglobulin A) deficient have a greater chance of developing anaphylactic shock.1 IVIG can cause renal dysfunction and renal failure, especially with preparations that are very concentrated or have a high sugar content.9
Managing Side Effects
As with any treatment, IVIG infusion has side effects. The key to getting the best results while minimizing adverse effects is working closely with your healthcare team. Here you will find a downloadable, printable document of helpful tips in decreasing the serious side effects of IVIG infusion. Discuss this information with your healthcare team prior to treatment.
IVIG temporarily increases the platelet count in about 80 percent of ITP patients.2 The duration of the response varies and the treatment can be repeated when the platelet count drops.
IVIg does not work very well for those ITP patients who have anti-GPIbalpha antibodies on their platelets.6,7
