Gammagard S/D Dosage

Gammagard S/D is typically given as an intravenous infusion (injected into the veins, IV for short).

Your dose depends on your body weight, certain lab results, and what you’re using Gammagard S/D for. In general:

• PI: The typical dose is 300 mg/kg to 600 mg/kg IV every 3 to 4 weeks.
• CLL: The typical dose is 400 mg/kg IV every 3 to 4 weeks.
• ITP: The typical dose is 1 gram/kg IV as a single dose. You might need up to 3 doses on different days, depending on your platelet count.
• Kawasaki syndrome: The typical dose is 1 gram/kg IV as a single dose. An alternative option is 400 mg/kg IV for four days beginning within seven days of when your child's fever started. Gammagard S/D is usually given with aspirin.

Your provider will adjust the dose based on whether it's helping your condition, whether you're having side effects, whether you've been exposed to measles, and whether you're at risk of measles exposure (e.g., traveling to certain places).
