What is IVIG and Why Is It Used?
Intravenous immunoglobulin (IVIG) is a therapy made from donated human plasma that contains antibodies. It's administered directly into a vein to help people with weakened or overactive immune systems. Healthcare providers use IVIG to treat a variety of conditions, including primary immunodeficiencies, autoimmune disorders like lupus and myasthenia gravis, and neurological diseases such as Guillain-Barré syndrome. The treatment works by providing the antibodies your body needs to fight infections or by helping to regulate an improper immune response.
Immediate Sensations: During and Right After the Infusion
During an IVIG infusion, medical staff monitor vital signs and the infusion typically starts slowly and increases gradually. While some individuals feel fine, it's common to experience mild discomforts like dizziness, nausea, or headache. Report any itching, chills, or discomfort to the nurse so they can adjust the rate or provide medication.
Common Immediate and Short-Term Side Effects
Most side effects after IVIG are mild, temporary, and often described as 'flu-like'. They usually subside within a day or two.
- Headache: A very common side effect, often relieved with pain relievers and hydration.
- Fatigue: Feeling tired is expected; rest is recommended after treatment.
- Flu-Like Symptoms: Includes muscle aches, chills, malaise, and sometimes a low-grade fever, typically occurring within hours of infusion.
- Nausea and Dizziness: More common in initial treatments.
Potential Delayed Reactions and Positive Outcomes
Some reactions can be delayed, appearing hours to days later, such as severe headaches. Rare but serious delayed side effects include aseptic meningitis, blood clots, or kidney problems. Seek medical attention for symptoms like a severe headache with a stiff neck, confusion, swelling in limbs, or difficulty breathing.
Positive effects of IVIG often emerge over time, typically within weeks to months. These include fewer infections, increased energy, and reduced disease symptoms.
| Feature | Immediate Effects (During or within 24 hours) | Delayed Effects (Days to Weeks Later) |
|---|---|---|
| Common Side Effects | Headache, fatigue, mild fever, chills, nausea, muscle aches | Prolonged or severe headaches, skin reactions |
| Serious Side Effects (Rare) | Allergic reaction, changes in blood pressure, chest pain | Aseptic meningitis, blood clots, kidney dysfunction |
| Positive Effects | Often not immediately noticeable, though some feel best right after infusion | Fewer infections, increased energy, reduced symptoms, improved mobility |
Managing Post-Infusion Feelings
Strategies to manage post-IVIG feelings include staying hydrated, pre-medication, and rest. Communicating any discomfort to your nurse is also important.
Conclusion
How you feel after getting IVIG varies. Mild, temporary flu-like symptoms are common and manageable. Positive impacts, such as a stronger immune system and improved quality of life, typically appear over time.
