Typical dosage for Gammagard
Your healthcare team will determine your dose of Gammagard based on different factors, such as your body weight and IgG levels.
In general:
-
Primary immunodeficiency: Gammagard can be given as an infusion into the veins (intravenous, IV) or under the skin (subcutaneous, SC, SQ, subQ).
- IV: The typical dose ranges from 300 mg/kg to 600 mg/kg every 3 to 4 weeks.
- SC: Your prescriber will calculate your initial dose based on your previous dose of IV immune globulin therapy. They'll calculate your maintenance dose based on how well your body responds and your target IgG level; it's typically given once every week.
-
Multifocal motor neuropathy: The typical dose ranges from 0.5 grams/kg to 2.4 grams/kg given IV once every month.
-
Chronic inflammatory demyelinating polyneuropathy:
- Induction dose: The typical dose is 2 grams/kg total, divided and given IV over 2 to 5 days.
- Maintenance dose: The typical dose is 1 gram/kg total, divided and given IV over 1 to 4 days. The maintenance dose is repeated every 3 weeks.
Your prescriber will adjust the dose based on if it's helping your condition, if you're having side effects, and if you're at risk of or exposed to measles (e.g., traveling to certain places).
