Human Normal Immunoglobulin
About Human Normal Immunoglobulin
Human Normal Immunoglobulin is an injection used to protect the body against infections and to treat certain inflammatory conditions. It is prescribed for people whose immune systems do not make enough of their own protective antibodies. It is also used to treat specific autoimmune disorders where the body mistakenly attacks its own healthy tissues.
This medicine is given regularly, with the frequency depending on your specific condition and how your body responds to treatment. Because it is given as an injection or infusion, its absorption is not affected by food, though drinking plenty of fluids before your treatment is highly recommended. Incorporating simple habits like practising good hand hygiene and avoiding close contact with sick individuals can further support your immune health.
While taking Human Normal Immunoglobulin, some people may experience mild side effects like headaches, chills, or redness at the injection site. It is important to watch for more serious symptoms, such as severe back pain, a sudden decrease in urination, or chest discomfort, and consult your doctor immediately if these occur.
Before you begin treatment, talk to your doctor if you have pre-existing kidney disease, diabetes, high blood pressure, or a history of blood clots. Do not take this medicine if you have had a severe allergic reaction to immunoglobulin therapies in the past, or if you have selective IgA deficiency with anti-IgA antibodies.
This medicine can interfere with live virus vaccines, making them less effective. Avoid drinking alcohol or smoking during treatment, as they can worsen side effects like dehydration and headaches. If you are pregnant, breastfeeding, or an older adult, consult your doctor or pharmacist to discuss the risks and benefits before starting this therapy.

Patients Concern
Disease/Condition Glossary
Immunoglobulin deficiency: Immunoglobulin deficiency indicates low levels of antibodies in the body due to decreased ability or inability to produce enough antibodies. It can be primary immunodeficiency (PID) and acquired or secondary immunodeficiency (SID). PID is congenital and a disorder present from birth. In PID, there is. On the other hand, SID is an acquired disorder that you get later in life. Immunoglobulin deficiency can lead to recurrent infections and ineffective antimicrobial treatment.
Primary immune thrombocytopenia: In this condition, platelet levels are decreased in the blood. This condition causes easy bruising or bleeding. Children may also experience purplish spots on the lower legs. In children, this condition usually resolves without any treatment. However, adults may require treatment to control bleeding.
Guillain-Barre syndrome: It is a rare condition in which the immune system attacks the nerves due to an acute bacterial or viral infection. Symptoms include weakness and tingling in the legs and feet that can spread to the upper body. Some patients may also develop paralysis.
Kawasaki disease: It is the inflammation of the blood vessels that is characterised by rashes and fever. It can also affect lymph nodes and cause symptoms in your nose, mouth, and throat. This condition is seen in young infants and children.
Chronic Inflammatory Demyelinating Neuropathy (CIDP): It is a condition in which nerves in the body are affected. Symptoms include slow reflexes and weakness of the arms and legs.
Multifocal motor neuropathy: It is a condition in which motor nerves (nerves that control movements and actions) are affected due to abnormal responses of the immune system. Symptoms include weakness in the upper and lower arms, cramps, involuntary twitching, and atrophy (wasting) of affected muscles.
FAQs
Human Normal Immunoglobulin is used to treat immunoglobulin (antibody) deficiency and certain inflammatory disorders.
The Human Normal Immunoglobulin contains Human normal immunoglobulin, which helps restore the deficient immunoglobulins or antibodies in the body. Antibodies are an essential part of the immune system that help to reduce infection and inflammation. They act by identifying, attacking, and thereby destroying the antigen or foreign body that has entered or is present in the body.
Human Normal Immunoglobulin may alter some blood test results for a certain time, so inform your doctor that you have Human Normal Immunoglobulin before undergoing blood tests. Taking any vaccines (especially live vaccines) at least three months after taking Human Normal Immunoglobulin is not recommended as this medicine may make the vaccines less effective.
Human Normal Immunoglobulin should be used with caution in patients with diabetes if this medicine is given as an infusion, as it may alter blood sugar levels. Human Normal Immunoglobulin doesn't contain sugar; however, it can be diluted in a special sugar solution before giving the infusion.
Human Normal Immunoglobulin is usually well-tolerated. However, some patients may experience side effects such as swelling or hardening at the injection site and headache, pain in the face, back, arms, legs, joints, or neck, fever, flu-like illness (runny nose and sore throat), blisters in the mouth, and throat, and throat tightness. If any side effects persist or get worse, inform your doctor immediately.
It is a condition in which there is a decrease in antibody levels in the body due to decreased ability or inability to produce enough antibodies. It can be present from birth (primary) or acquired during the later stages of life (secondary).
Certain vaccinations, such as those for chickenpox, measles, mumps, and rubella, may become less effective when administered with Human Normal Immunoglobulin.

Yes, Human Normal Immunoglobulin can cause kidney damage but not in everyone. Patients having a pre-existing kidney problem, hypovolemia (a decrease in the volume of circulating blood) and diabetes are at risk of developing kidney failure. Additionally, patients who are overweight, above 65 years of age and who are taking medicines that can cause kidney damage are also at risk of developing kidney failure. Therefore, please inform your doctor if you have any pre-existing kidney problems.
No, hair loss is not a commonly reported side effect of Human Normal Immunoglobulin. If you experience hair loss, it might be due to some other underlying problem. Please consult your doctor if bothers you.

It is usually given by a trained healthcare professional, though some patients may be taught how to inject it at home. Talk to your doctor about the safest way to receive your treatment.
You should avoid receiving live vaccines, such as the measles, mumps, rubella (MMR), or chickenpox vaccine, while receiving Human Normal Immunoglobulin, as the medicine can make these vaccines less effective. Non-live vaccines are generally safe but may not work as well. Always talk to your doctor or pharmacist before scheduling any vaccinations.
Headaches are a very common side effect of Human Normal Immunoglobulin infusions. They are often caused by the speed of the infusion or mild dehydration.
