Updated GamaSTAN® S/D Indications & Hepatitis A Outbreaks
Date: July 28, 2017
Grifols has made some important changes to the prescribing information for GamaSTAN® S/D. The following are dosing instruction changes for the hepatitis A pre and post exposure prophylaxis indication.
- GamaSTAN S/D in a dose of 0.05 mL/lb (0.1 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.
|Length of Stay||Dose Volume|
|Up to 1 month||0.1 mL/kg|
|Up to 2 months||0.2 mL/kg|
|2 months or longer||Repeat dose of 0.2 mL/kg every two months|
This dosage change is based on lower concentrations of anti-hepatitis A virus (HAV) due to the decreasing prevalence of previous HAV infection among plasma donors.

Hepatitis A Outbreaks

This advisory is directed at healthcare providers and care centers that provide services to homeless people or persons using illicit drugs. As a reminder, the hepatitis A vaccine is also routinely recommended for the following groups:
- persons with chronic liver disease, including those with hepatitis B or C virus infection
- users of injection and noninjection illicit drugs
- men who have sex with men
- persons traveling to or working in countries that have high or intermediate levels of HAV transmission
- children, starting at age 1 year
- any person wishing to obtain immunity to HAV
