• Antiemetic agents
• Antihistamines
• NSAIDs (nonsteroidal anti-inflammatory drugs):
  • Ibuprofen (Motrin, Advil)
  • Naproxen (Aleve)

Rare or Serious Side Effects

Hemolytic reactions

IVIG may cause hemolysis, which is the destruction of red blood cells. This can result in hemolytic anemia, which can cause fatigue, shortness of breath, and a pale appearance.

Tổn thương phổi cấp tính liên quan đến truyền máu (TRALI)

This is a rare but serious condition characterized by acute respiratory distress. TRALI can lead to difficulty breathing, chest pain, and coughing up blood. If TRALI occurs, IVIG infusion should be abruptly stopped, and respiratory support should be provided immediately.

Acute kidney failure

Some patients may experience kidney injury or failure. The risk is higher in those with preexisting kidney conditions. Kidney function should be monitored closely during treatment.

Immune globulin may also be administered:

• Subcutaneously (SCIG), where the product is injected into fatty tissue beneath the skin rather than directly into the vein. This option has been gaining popularity in recent years, as it can be done at home for patients with primary immunodeficiency (PID) and chronic inflammatory demyelinating polyneuropathy.

MỘTn infusion pump is programmed to deliver the Điều trị IVIG at a predetermined rate to ensure the body does not experience any adverse reactions.

Pre-medications are often taken to minimize or prevent side effects, including headaches, fatigue, and allergic reactions.

How Long Do IVIG Infusions Take?

How Often Is IVIG Infusion Therapy Administered?

Typically, IVIG treatments will be administered every 3 to 4 weeks. Initial IVIG doses are generally administered in divided doses over several days.

Subcutaneous IG infusions (SCIG) injected into the fatty tissue under the skin require more frequent dosing (daily or two to three times per week).
