What Are Immune Globulin (Ig) Injections?

Immune globulin injections—also known as immunoglobulin (Ig) injections—contain highly purified antibodies (IgG) derived from healthy donor plasma. They help fight infections, boost immune function, and reduce the risk of life-threatening diseases. Commonly administered as intravenous immunoglobulin (IVIG) or intramuscular immunoglobulin (IMIG), these injections are essential for primary immunodeficiency, autoimmune disorders, immune deficiency, and certain infectious diseases.

What Is an Important Nursing Consideration When Administering IV Immune Globulin (IVIG)?

Nursing consideration: Carefully monitor for allergic reactions, infusion rates, and changes in vital signs. Pre-medicate if required (with antihistamines or corticosteroids), use a dedicated IV line and always have emergency equipment available. Observe for adverse effects such as fever, chills, or anaphylaxis throughout administration.

How to Administer an Immunoglobulin Injection?

IVIG: Infused intravenously, typically in a clinical setting by a nurse or doctor, using proper sterile technique and appropriate infusion rates. IMIG: Injected into large muscle groups (such as the thigh or gluteus), using a prefilled syringe, per physician’s instructions. Always follow official dosage, timing, and administration protocols for safe injection.

Does Immune Globulin Need to Be Refrigerated?

Yes. Immune globulin (IVIG and IMIG) should be stored refrigerated (2°C–8°C/36°F–46°F) and protected from light. Do not freeze. Allow the syringe or vial to reach room temperature before injection for comfort and efficacy.

How Long Does an Immunoglobulin Shot Last?

The protective effects typically last 3 to 4 weeks. Your doctor may recommend regular (monthly or as-needed) injections, depending on your condition and immune status.

Does IVIG Need to Be Filtered?

Yes, many IVIG products require inline filtration according to manufacturer instructions, to remove particulate matter and prevent infusion reactions. Always check product labeling for the need for specific filters.

When to Inject Immunoglobulin?

Injection timing depends on your diagnosis: Primary immune deficiency: Regularly, every 3–4 weeks Exposure to infectious diseases: As soon as possible post-exposure Other indications: Follow your physician’s instructions for dosage and timing

Are Immunoglobulin Shots Painful?

Some pain, swelling, or redness at the injection site may occur, especially with IM injections. IV infusions are usually well-tolerated but may cause headaches, chills, or flu-like symptoms. Severe reactions are uncommon but possible—report any unusual side effects immediately.

Is Immune Globulin the Same as IVIG?

IVIG (intravenous immunoglobulin) is a specific form of immune globulin given via IV infusion; all IVIG is immune globulin, but immune globulin may also refer to intramuscular (IMIG) or subcutaneous (SCIG) forms.

How Much Does an Immunoglobulin Shot Cost?

Immunoglobulin therapy can range from $100 to $10,000+ per dose depending on the brand, dosage, and insurance coverage. IVIG is generally more expensive than IM injections. Exact pricing depends on individual protocol and pharmacy rates.

How Quickly Does Immunoglobulin Work?

Immunoglobulin can offer clinical benefits within hours to days, quickly restoring immune defenses against infection or helping control autoimmune flare-ups.

Who Needs Immune Globulin?

Candidates for immune globulin therapy include: Primary immunodeficiency patients Individuals exposed to hepatitis, measles, or rabies Bone marrow or organ transplant recipients Autoimmune disease and certain neurological disorder patients Those with severe infections or weak immune response
