|
|
| Use |
|
|
Household and sexual contacts of persons with hepatitis A, measles,
varicella, and possibly rubella; travelers to high-risk areas outside tourist
routes; staff, attendees, and parents of diapered attendees in day-care center
outbreaks |

|
|
| Contraindications |
|
|
Thrombocytopenia, hypersensitivity to immune globulin, thimerosal, IgA
deficiency |

|
|
| Warnings/Precautions |
|
|
Skin testing should not be performed as local irritation can occur and be
misinterpreted as a positive reaction; do not administer I.V.; IG should
not be used to control outbreaks of measles; epidemiologic and laboratory
data indicate current IMIG products do not have a discernible risk of
transmitting HIV |

|
|
| Adverse
Reactions |
|
|
>10%: Local: Pain, tenderness, muscle stiffness at I.M. site
1% to 10%:
Cardiovascular: Flushing
Central nervous system: Chills
Gastrointestinal: Nausea
<1%: Lethargy, fever, urticaria, angioedema, erythema, vomiting, myalgia,
hypersensitivity reactions |

|
| Drug
Interactions |
|
|
Increased toxicity: Live virus, vaccines (measles, mumps, rubella); do not
administer within 3 months after administration of these
vaccines |

|
|
| Stability |
|
|
Keep in refrigerator; do not freeze |

|
|
| Mechanism of
Action |
|
|
Provides passive immunity by increasing the antibody titer and
antigen-antibody reaction potential |

|
|
| Pharmacodynamics/Kinetics |
|
|
Duration of immune effect: Usually 3-4 weeks
Half-life: 23 days
Time to peak serum concentration: I.M.: Within 24-48 hours
|

|
|
| Usual Dosage |
|
|
I.M.:
Pre-exposure prophylaxis upon travel into endemic areas (hepatitis A vaccine
preferred):
0.02 mL/kg for anticipated risk 1-3 months
0.06 mL/kg for anticipated risk >3 months
Repeat approximate dose every 4-6 months if exposure continues
Postexposure prophylaxis: 0.02 mL/kg given within 2 weeks of exposure
Measles:
Prophylaxis: 0.25 mL/kg/dose (maximum dose: 15 mL) given within 6 days of
exposure followed by live attenuated measles vaccine in 3 months or at 15 months
of age (whichever is later)
For patients with leukemia, lymphoma, immunodeficiency disorders, generalized
malignancy, or receiving immunosuppressive therapy: 0.5 mL/kg (maximum dose: 15
mL)
Poliomyelitis: Prophylaxis: 0.3 mL/kg/dose as a single dose
Rubella: Prophylaxis: 0.55 mL/kg/dose within 72 hours of exposure
Varicella:: Prophylaxis: 0.6-1.2 mL/kg (varicella zoster immune globulin
preferred) within 72 hours of exposure
IgG deficiency: 1.3 mL/kg, then 0.66 mL/kg in 3-4 weeks
Hepatitis B: Prophylaxis: 0.06 mL/kg/dose (HBIG preferred)
