Great question! IVIG (Intravenous Immunoglobulin) is a treatment made from concentrated antibodies collected from thousands of healthy donors. It's delivered directly into a vein through an IV drip at a healthcare facility.
In myasthenia gravis, the immune system mistakenly produces harmful antibodies (called autoantibodies) that attack the connection between nerves and muscles. This is what causes the muscle weakness and fatigue associated with MG. IVIG works by introducing a protein called the neonatal Fc receptor (FcR) into the bloodstream. This may signal the body to clear out excess antibodies — including those harmful autoantibodies causing MG symptoms.
Think of it like sending in a cleanup crew to remove the troublemakers! IVIG is most commonly used as a short-term treatment, particularly during:
- Flare-ups — periods when symptoms suddenly worsen
- Myasthenic crisis — a rapid, serious worsening of symptoms
- Before surgery — to help stabilize symptoms
It's worth knowing that relief isn't always immediate — it may take a few weeks to notice improvement. Since the body keeps producing new autoantibodies, the effects are temporary, and ongoing treatment may be needed.
Always talk to your doctor about whether IVIG is the right fit for your treatment plan.
