GamaSTAN S/D Dosage

Generic name: Human Immunoglobulin A 0.165g in 1mL
Dosage form: injection

Medically reviewed on October 30, 2017.

GamaSTAN S/D is administered intramuscularly (see PRECAUTIONS), preferably in the anterolateral aspects of the upper thigh and the deltoid muscle of the upper arm. The gluteal region should not be used as an injection site because of the risk of injury to the sciatic nerve.(10) Doses over 10 mL should be divided and injected into several muscle sites to reduce local pain and discomfort. An individual decision as to which muscle is injected must be made for each patient based on the volume of material to be administered.

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.

Hepatitis A

GamaSTAN S/D in a dose of 0.01 mL/lb (0.02 mL/kg) is recommended for household and institutional hepatitis A case contacts.

The following doses of GamaSTAN S/D are recommended for persons who plan to travel in areas where hepatitis A is common.(3)

Length of Stay Dose Volume
Less than 3 months 0.02 mL/kg
3 months or longer 0.06 mL/kg (repeat every 4–6 months)

Measles (Rubeola)

GamaSTAN S/D should be given in a dose of 0.11 mL/lb (0.25 mL/kg) to prevent or modify measles in a susceptible person exposed fewer than 6 days previously.(7)

A susceptible child who is exposed to measles and who is immunocompromised should receive a dose of 0.5 mL/kg (maximum dose, 15 mL) of GamaSTAN S/D immediately.(8)


If Varicella-Zoster Immune Globulin (Human) is unavailable, GamaSTAN S/D at a dose of 0.6 to 1.2 mL/kg, promptly given, may also modify varicella.(5)


Some studies suggest that the use of GamaSTAN S/D in exposed, susceptible women can lessen the likelihood of infection and fetal damage; therefore, GamaSTAN S/D at a dose of 0.55 mL/kg may benefit those women who will not consider a therapeutic abortion.(4)

Immunoglobulin Deficiency

GamaSTAN S/D may prevent serious infection in patients with immunoglobulin deficiencies if circulating IgG levels of approximately 200 mg/100 mL plasma are maintained. The recommended dosage is 0.66 mL/kg (at least 100 mg/kg) given every 3 to 4 weeks.(6) A double dose is given at onset of therapy; some patients may require more frequent injections.
