Appropriate studies have not been performed on the relationship of age to the effects of hepatitis B immune globulin injection in the pediatric population. However, safety and efficacy have been established in children who are receiving similar medicines for prevention of hepatitis B infection after exposure to hepatitis B virus.


Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of hepatitis B immune globulin injection in the elderly.
