Drug Interaction:
Interacting drugs - summary
+ Hepatitis B vaccine
Immunosuppressants- administration of HBV to persons receiving immunosuppressant drugs, including high-dose corticosteroids orradiation therapy, result in an insufficient response to immuninization. They may remain susceptible despite immunization.
Interleukin- 2 - natural interleukin -2 may boost systemic immune response to HBsAg
in immunodeficient nonresponders to hepatitis B vaccination, but a
recombinant interleukin- 2 did not augement response to hepatitis B
vaccine in healthy adults in one study.
Yellow fever vaccine- concurrent vaccination against hepatitis B and yellow fever viruses in
one study reduced the antibody titer expected from yellow fever vaccine. Separate these vaccinations by 1 month if possible.
Anticoagulants- as with drugs admministered by IM injection give hepatitis B vaccine
with caution to persons receiving anticoagulant therapy
Indication:
Prophylaxis against Hepatitis B infection

Special Precautions-
Infection- serious active infection is raeson to dealy use of Hepatitis B vaccine, except when withholding the vaccine entails greater risk.
Special risk patients- cautiously administer to individuals with severely compromised cardiopulmonary status or when a febrile or systemic reaction could be a significant risk.
Warnings-
Hypersensitivity- have epinephrine 1:1000 immeiately avilable.
Immunosuppressed patients- may require large vaccine doses and may not respond as well as healthy individuals.
Limitations- no hepatitis B vacine will protect against hepatitis A,C, and E viruses or other viruses known to infect the liver.
Elderly- immunogenicity of hepatitis B vaccine is some what reduced in persons > 40 years of age.
Pregnancy-
Safety for use during pregnacy has not been established. Use only when clearly needed.
Lactation- safety for use in the nursing mother has not been established.
Children- Hepatitis B is well tolerated and highly immunogenic ininfants and children of all ages. Newborns also respond well.
Dosages/ Overdosage Etc:
Prophylaxis against Hepatitis B infection
Dosage-
For IM use.never inject IV. The deltoid muscle is the preferred site in adults. Injections given in the
buttocks frequently are given into fatty tissue instead of into muscle and have resulted in lower
seroconversion rate than expected.
Missed dose-
1. If you miss a dose of this medicine, and remember it on the day it should be taken, take it as directed.
2. However, if you do not remember the mised dose until the next day,take the missed dose at that time and reschedule your every-other-day doses from then.
