PRECAUTIONS: Before getting hepatitis B vaccine, tell your doctor or pharmacist if you are allergic to it; or to yeast; or other vaccines; or if you have any other allergies. Some vials and prefilled syringes may use latex rubber stoppers or plungers. Tell your doctor if you are allergic to latex. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.
Before using this medication, tell your doctor or pharmacist your medical history, especially of: bleeding problems (such as hemophilia, low platelets, anticoagulant treatment), current illness with fever.
If you are a hemodialysis patient, you may not respond as well to the vaccine and will need to have hepatitis B antibody levels checked yearly. If antibodies drop too low over time, you may be given another dose of vaccine (often called a booster shot).
If you have decreased immune function from other medications (see also Drug Interactions) or other illness (such as HIV, leukemia, lymphoma, other cancer), your body may not make enough antibodies to protect you from hepatitis B infection. Antibody levels may be checked after the vaccine series.
The elderly may not make as many antibodies to the vaccine. Talk to your doctor for more details.
During pregnancy, this medication should be used only when clearly needed. Discuss the risks and benefits with your doctor.
It is unknown whether this drug passes into breast milk. Consult your doctor before breast-feeding.
