Intravenous Immunoglobulin (IVIG) Therapy: Benefits, Uses, and Risks
Summary of Key Points
Intravenous immunoglobulin (IVIG) is a treatment used for various immune-related conditions. It works by providing antibodies that support your immune system in fighting infections or regulating autoimmune responses. IVIG therapy is commonly prescribed for conditions such as primary immunodeficiency, Guillain-Barré syndrome, and chronic inflammatory demyelinating polyneuropathy (CIDP). Always consult your healthcare provider before starting or adjusting IVIG treatment. You can also connect with one of our telemedicine providers for personalized care.

IVIG Administration Instructions
IVIG is administered intravenously by a healthcare professional. The infusion process may take several hours, depending on the dose and your specific condition. Staying well-hydrated before and after the infusion can help reduce the risk of side effects. Your healthcare provider will monitor you throughout the infusion to ensure your safety. If you experience any unusual symptoms, such as difficulty breathing or chest pain, notify your provider immediately.
Adverse Reactions and Side Effects of IVIG
Like all medications, IVIG can cause side effects. Some are common and mild, while others are rare but more serious. If you experience any side effects, contact your healthcare provider. You can also consult one of our telemedicine providers for advice.
Common Side Effects:
Headache: Mild to moderate headache during or after the infusion.
Nausea: Feeling nauseous during or after the infusion.
Fatigue: Feeling unusually tired or weak after treatment.
Less Common Side Effects:
Fever: A mild fever may develop after the infusion.
Chills: Shivering or feeling cold during or after the infusion.
Rare but Serious Side Effects:
Allergic Reaction: Symptoms such as rash, itching, swelling, or difficulty breathing.
Blood Clots: Pain, swelling, or redness in the legs, or sudden chest pain and shortness of breath.
Kidney Problems: Decreased urine output or swelling in the legs.
Contraindications for IVIG Therapy
A contraindication is a specific situation or condition where a medication should not be used because it may be harmful. For intravenous immunoglobulin (IVIG), certain conditions make it unsafe. Below are the main contraindications for IVIG and the reasons why it is not recommended in these situations:
Severe allergic reactions to immunoglobulins: If you have had a serious allergic reaction (anaphylaxis) to immunoglobulins in the past, IVIG should not be used. Your immune system may react strongly, causing life-threatening symptoms such as difficulty breathing, swelling, or a drop in blood pressure.
IgA deficiency with antibodies against IgA: Some individuals have a deficiency in a specific type of immunoglobulin called IgA. If you also have antibodies against IgA, receiving IVIG can trigger a severe allergic reaction, as the body may recognize the IgA in IVIG as a foreign substance and attack it.
Kidney disease: IVIG can sometimes cause kidney problems, especially in individuals with pre-existing kidney disease. In rare cases, it can lead to kidney failure, so it is contraindicated in patients with severe kidney disease unless absolutely necessary.
Blood clotting disorders: IVIG can increase the risk of blood clots, so it is contraindicated in individuals with a history of blood clots or conditions that make them more prone to clotting, such as certain heart conditions or prolonged immobility.
Drug to Drug Interactions with IVIG
Intravenous immunoglobulin (IVIG) can interact with other medications, potentially affecting their effectiveness or increasing the risk of side effects. Below are some medications that may interact with IVIG:
Live vaccines: IVIG can interfere with the effectiveness of live vaccines, such as the MMR (measles, mumps, and rubella) vaccine and the varicella (chickenpox) vaccine. You may need to wait several months after receiving IVIG before getting these vaccines.
Cyclosporine (Neoral, Sandimmune): This immunosuppressant drug can increase the risk of kidney problems when taken with IVIG.
Aminoglycoside antibiotics (Gentamicin, Tobramycin): These antibiotics can increase the risk of kidney damage when combined with IVIG.
Anticoagulants (Warfarin, Coumadin): IVIG can increase the risk of blood clots, which may require adjusting the dose of blood thinners like warfarin.
Intravenous Immunoglobulin in Pregnancy
Is it safe to take intravenous immunoglobulin (IVIG) during pregnancy?
IVIG therapy is generally considered safe during pregnancy, especially when the benefits outweigh the potential risks. It is often prescribed to manage autoimmune conditions or immune deficiencies in pregnant women. However, it is crucial to discuss the possible risks and benefits of IVIG treatment with your healthcare provider before starting therapy. Every pregnancy is unique, and your provider will work with you to determine the best course of action for both you and your baby.
Intravenous Immunoglobulin While Breastfeeding
Is it safe to take intravenous immunoglobulin while breastfeeding?
Yes, IVIG infusion is typically considered safe while breastfeeding. Immunoglobulins are naturally present in breast milk and can help support your baby’s immune system. However, as with any medication, it’s important to consult your healthcare provider before beginning IVIG therapy while breastfeeding to ensure it’s the right choice for your specific situation.
Estimated Cost of IVIG Therapy
The cost of intravenous immunoglobulin (IVIG) can vary depending on the dosage and the specific brand of the medication. Without insurance, the estimated cost of a 30-day supply of IVIG using a GoodRX coupon can range from $5,000 to $10,000 or more. Prices may fluctuate based on the pharmacy and the formulation of the drug. Be sure to check with your pharmacy and explore financial assistance options if needed.
Possible Alternatives to IVIG Therapy
For some conditions, alternative treatments or lifestyle changes may help manage symptoms or improve overall health. Always discuss these options with your healthcare provider before making any changes to your treatment plan. You can also schedule a telemedicine appointment with one of our providers to explore these alternatives.
- Primary immunodeficiency: Alternatives may include subcutaneous immunoglobulin (SCIG) therapy, preventive antibiotics, or lifestyle adjustments such as avoiding exposure to infections and maintaining a healthy diet.
- Chronic inflammatory demyelinating polyneuropathy (CIDP): Alternatives may include corticosteroids, plasma exchange (plasmapheresis), or physical therapy to help manage symptoms.
- Guillain-Barré syndrome: Plasma exchange or corticosteroids may be used as alternatives to IVIG. Physical therapy and rehabilitation are also key components of treatment.
- Myasthenia gravis: Alternatives may include medications like pyridostigmine (Mestinon), corticosteroids, or immunosuppressants. In some cases, surgery to remove the thymus gland (thymectomy) may be recommended.
- Kawasaki disease: High-dose aspirin and corticosteroids may be used as alternatives to IVIG in certain cases. Early treatment is essential to prevent complications.
- Idiopathic thrombocytopenic purpura (ITP): Alternatives may include corticosteroids, thrombopoietin receptor agonists, or splenectomy (removal of the spleen) in more severe cases.
- Multiple sclerosis (MS): Alternatives include disease-modifying therapies such as interferons, glatiramer acetate (Copaxone), or oral medications like fingolimod (Gilenya). Lifestyle changes, such as regular exercise and a balanced diet, can also help manage symptoms.
- Hepatitis A: Vaccination is the most effective way to prevent hepatitis A. If you have been exposed to the virus, immune globulin or antiviral medications may be used as alternatives.
- HIV infection: Antiretroviral therapy (ART) is the standard treatment for HIV. Maintaining a healthy lifestyle, including a balanced diet and regular exercise, can also help manage the condition.
- Bone marrow disorders: Treatment options depend on the specific disorder but may include chemotherapy, radiation therapy, or stem cell transplants. Your healthcare provider will guide you through the best options for your condition.
