HEPATITIS B VACCINE - INJECTION
COMMON BRAND NAME(S): Engerix-B, Recombivax HB
USES: This vaccine is used to help prevent infection from the hepatitis B virus. Hepatitis B infection can cause serious problems including liver failure, persistent hepatitis B infection, cirrhosis, and liver cancer. Preventing infection can prevent these problems.
Hepatitis B vaccine is a genetically engineered (man-made in the laboratory) piece of the virus. It does not contain live virus, so you cannot get hepatitis from the vaccine. This vaccine works by helping the body produce immunity (through antibody production) that will prevent you from getting infection from hepatitis B virus. Hepatitis B vaccine does not protect you from other virus infections (such as HIV virus which causes AIDS; hepatitis A, hepatitis C or hepatitis E; HPV virus which causes genital warts and other problems).
The vaccine is recommended for people of all ages, especially those at an increased risk of getting the infection. Those at an increased risk include health care personnel, laboratory workers who handle blood and patient specimens, police, fire and emergency medical personnel who give first aid treatment, hemophiliacs, dialysis patients, people who live with or spend much time with people with persistent hepatitis B infections, people with multiple sex partners, men who have sex with men, sex workers, injection drug abusers, and people traveling to high-risk areas.
HOW TO USE: Read the Vaccine Information Statement available from your health care professional before receiving the vaccine. If you have any questions, ask your health care professional.
A series of 2 to 4 injections is usually used over a 6- to 12-month period. Your doctor will give you a vaccination schedule, which you must follow closely for best effectiveness. If you have an illness with fever at the time a vaccination is scheduled, your doctor may choose to delay the injection until you are better.
The dosage and vaccination schedule is based on your age, medical condition, risk of hepatitis B exposure, and the brand of vaccine used.
If you are receiving the first hepatitis B vaccine injection at a time when your doctor feels you may have been exposed to hepatitis B, you will also receive an injection of hepatitis B immune globulin (HBIG). HBIG is a dose of antibodies against the virus and will immediately help protect you from developing an infection. These antibodies only last a few months. For long-term protection, it is important to follow your vaccination schedule for the hepatitis B vaccine exactly.

Infrequently, temporary symptoms such as fainting/dizziness/lightheadedness, vision changes, numbness/tingling, or seizure-like movements have happened after vaccine injections. Tell your health care provider right away if you have any of these symptoms soon after receiving an injection. Sitting or lying down may relieve symptoms.

PRECAUTIONS: Before you receive this vaccine, tell the health care professional 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 vaccine, tell your health care professional 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 vaccine should be used only when clearly needed. Discuss the risks and benefits with your doctor.
It is unknown if this vaccine passes into breast milk. Consult your doctor before breast-feeding.
Some products that may interact with this vaccine include: chemotherapy, corticosteroids (such as prednisone, dexamethasone), drugs that weaken the immune system (such as cyclosporine, tacrolimus, mycophenolate).
Other vaccines may be given at the same time as hepatitis B vaccine, but should be given with separate syringes and at different injection sites.
OVERDOSE: Not applicable.
NOTES: As with any vaccine, this vaccine may not fully protect everyone who receives it.
Laboratory and/or medical tests (such as hepatitis B antibody levels) may be performed periodically for some patients at risk of a poor response to the vaccine. Consult your doctor for more details.
Keep vaccine records for yourself and all of your children, and after your children are grown provide their records to them and their doctors. This will prevent unnecessary re-vaccinations.
MISSED DOSE: It is important to receive each vaccination as scheduled. Be sure to ask when each dose should be received and make a note on a calendar to help you remember.
STORAGE: Store in the refrigerator. Do not freeze. Keep all medications away from children and pets.
Do not flush medications down the toilet or pour them into a drain unless instructed to do so. Properly discard this product when it is expired or no longer needed. Consult your pharmacist or local waste disposal company.
