What is intravenous immunoglobulin IVIG?
Intravenous immunoglobulin (IVIG) is a blood product prepared from the serum of between 1000 and 15 000 donors per batch. It is the treatment of choice for patients with antibody deficiencies. For this indication, IVIG is used at a ‘replacement dose’ of 200–400 mg/kg body weight, given approximately 3-weekly.
Can I donate blood for IVIg treatment?
You’ll usually be given the same brand of IVIg, such as Flebogamma or Octagam, every time you have it to reduce the likelihood of a reaction. All blood donors for IVIg are carefully tested for certain diseases that could be passed on to you, such as hepatitis B, and they are only able to donate if their blood is safe.
What are the risks of bloodborne infections from IVIG infusions?
The risk of getting bloodborne infections from blood donors used to create IVIG infusions is considered extremely low. This is because of the purification process that donated blood plasma goes through, which helps destroy infectious organisms, such as bacteria and viruses.
How much IVIG should I take per month?
Your IVIg dosage depends on how much you weigh. The standard starting dosage is 400 to 600 mg/kg of your body weight per month. What Are the Possible Side Effects?
How many blood donors does it take to make IVIG?
Intravenous immunoglobulin (IVIG) is a blood product prepared from the serum of between 1000 and 15 000 donors per batch. It is the treatment of choice for patients with antibody deficiencies.
How is IVIG produced?
Immune globulin is prepared from pooled plasma from 3000-10,000 healthy blood donors. In some instances, blood from as many as 100,000 donors is used. The entire array of variable (antigen-binding) regions of antibodies in normal serum is contained in IVIG.
Is IVIG made from plasma?
First used in 1952 to treat immune deficiency, IVIg is a plasma protein product containing the pooled antibodies of thousands of donors.
Is IVIG donated?
Immunoglobulin -whether given as IVIG or SCIG – is created from source plasma that is donated from healthy people. There is no other way to create this treatment, so patients who use plasma products rely on people to donate plasma through a safe, relatively quick process for which their time may be reimbursed.
How long does it take to produce immunoglobulin?
A 5- to 10-day lag time occurs before IgM antibodies appear in blood, and peak IgM levels occur at 21 days. During the response, memory B cells are also produced, and they remain in the lymph node germinal centers or recirculate between the lymph node and the spleen.
How much does IVIG cost?
Since the average cost per IVIG infusion in the USA has been reported to be $9,720, and patients on average received 4.3 infusions per month, the IVIG costs would be $41,796 per month.
Does IVIG change your DNA?
As shown in Fig. 2, even with more stringent criteria (less p value), consistently, fewer CpG markers altered in the KD1 vs FC comparison than the other two ones, which implies that IVIG treatment causes major alterations in DNA methylation patterns.
What is the difference between plasma and IVIG?
Intravenous immunoglobulin (IVIG) is a biological agent obtained through the fractionation of blood from 2000–16,000 patients. Plasma exchange (PLEX) is a blood separation technique thought to remove autoantibodies. Both IVIG and PLEX have been found to be effective disease stabilizing therapies for patients with MGC.
What antibodies are in IVIG?
IVIG also contains Natural Antibodies. Normal serum contains IgG, IgM, and IgA antibodies, which are referred to as natural antibodies because they are induced without deliberate immunization and are independent of antigenic exposure.
Does giving blood reduce immune system?
Will giving blood weaken my immune system? There is no evidence blood donation weakens the immune system. Blood donation is needed to keep the supply available to patients who need it. To best prepare for your donation get sleep, eat a good meal, and drink fluids.
Does donating plasma shorten your life?
This may indicate that donating blood is good for a person's overall health, but the researchers could not confirm this. However, they did point out that donating blood seems unlikely to shorten a person's life span.
Does giving blood plasma lower your immune system?
No, plasma donation will not lower your own antibody levels. In a healthy adult, the immune system is able to create new antibodies and replace your donated plasma within 48 hours. Whether or not you donate plasma, it is expected that antibody levels will fall naturally in all people after some months.
What is IVIg?
Intravenous immune globulin (IVIg) is a mixture of antibodies that is used to treat a variety of immune system disorders. It is made by gathering blood from thousands of donors to create a concentrated collection of antibodies.
Uses of IVIg
IVIG is given into a vein (intravenously), usually in a doctor’s office or hospital. It may also be given at home under specific arrangements and medical guidance.
IVIg Side Effects
This list does not cover all possible side effects. Contact your doctor or pharmacist if you notice any other side effects.

Drug interactions can be dangerous and, in rare cases, even life-threatening. Let your doctor know about all drugs and supplements you are using or considering to reduce the risk of drug interactions.
IVIg Dosage
IVIg dosage is personalized for each person and disease. The dose, infusion rate, dosage schedule, and duration of treatment can all vary depending on the condition. Researchers are still trying to find the optimal dose for each disease.
Why is IVIG important?
Because it is derived from donor blood, IVIG historically has carried with it the potential risk of transmitting infections. Since the 1980s, dedicated virus inactivation steps have been added to the purification process. Since the introduction of these techniques, there have not been any documented cases of IVIG-transmitted infections. Donor populations are also screened for the presence of HIV and hepatitis B and C, and in some cases, other viruses.
How is IVIG made?
It is typically given by slow delivery from a needle inserted into a blood vein. Each IVIG preparation is made from the pooled plasma of 3,000-10,000 blood donors, which is then purified to contain more than 90% antibodies (the natural proteins that your body normally makes to help you to fight infections and to serve other functions for the immune system). IVIG preparations are carefully screened during purification to detect and eliminate viral infections that could be transmitted through intravenous infusion (eg, hepatitis C virus). However, it is impossible to completely eliminate all possible viral infections from IVIG preparations.
Can IVIG bind to other medications?
Be sure to tell your doctor about all of the medications you are taking, including over-the-counter drugs and natural remedies. IVIG may bind to other medications given by vein or subcutaneously, inactivating them.
Is IVIG FDA approved?
IVIG is FDA-approved for the treatment of various immune deficiency states. In addition, it is used to treat Kawasaki disease, immune thrombocytopenic purpura (ITP), pemphigus vulgaris and certain autoimmune neurologic conditions. IVIG is also effective in treating dermatomyositis and certain types of vasculitis.
Why do I need IVIG therapy?
These conditions, like PIs, require low-dose IVIG therapy to avoid the risk of frequent and deadly infections. Cancers such as B-cell chronic lymphocytic leukemia (B-cell CLL) and multiple myeloma (MM) lead to humoral immunosuppression, and these conditions benefit from IVIG therapy.
How long does IVIG last?

What is IgG in IVIG?
IgG comprises more than 90% of the proteins in an IVIG preparation, and it is the principal component required for the therapeutic effect of IVIG. Some authors even consider IVIG to stand for intravenous IgG.[7] .
Why is IgG important?
IgG levels in blood serve as an essential yardstick to guide IVIG therapy. It is also used to assess the effectiveness of the treatment and helps to modify the IVIG course and frequency. Measuring IgG levels at different times to evaluate the peak plasma levels and trough levels can assess response to therapy.

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
What are the side effects of IVIG?
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
