Full Consumer Medicine Information (CMI)
This leaflet provides important information about using H-B-VAX II. You should also speak to your doctor, nurse, or pharmacist if you would like further
information or if you have any concerns or questions about using H-B-VAX II.
Where to find information in this leaflet:
1. Why am I or my child being given H-B-VAX II?
H-B-VAX II is a vaccine used to help prevent hepatitis B. The vaccine can be given
to newborns, infants, children, teenagers and adults.
What is Hepatitis B
Hepatitis B is an infection of the liver caused by the hepatitis B virus (HBV). It
can be caught by coming into contact with an infected person's blood, semen, vaginal
secretions, saliva or other body fluids. For example, if these infected fluids enter
your blood stream through a cut in your skin, you could become infected. Other situations
that could lead to infection include:
being born to a mother who carries the HBV
sexual contact with someone who is infected
living in the same house as someone who is infected
close family contact, for example, sharing razors or toothbrushes
having a job that involves exposure to human blood or body fluids, for example, some
health care workers
sharing needles for injecting drugs
travelling to areas where hepatitis B is common
People who have hepatitis B may not look or feel sick when infected. In fact, a person
could be infected by the virus six weeks to six months before symptoms occur. Some
people develop mild, flu-like symptoms. Others may become very ill and extremely tired,
develop yellowing of the skin and/or eyes (also called jaundice), dark urine and other
symptoms that require hospitalisation.
Most people recover completely from the HBV infection. However, there are some people,
particularly children, who may not have symptoms but continue to carry the virus in
their blood. They are called chronic carriers. These chronic carriers are infectious
and can spread the disease to others throughout their lives.
Babies who are infected with the HBV at birth, almost always go on to become chronic
carriers. The infection at birth is silent, and the babies appear healthy and continue
to remain healthy for many years.
However, after 30, 40 or 50 years they can become unwell and develop the symptoms
described above.
All chronic carriers run the risk of developing serious liver disease, such as cirrhosis
(scarring of the liver) or liver cancer.
Vaccination is recommended for adults who are at substantial risk of hepatitis B virus
infection.
How does it work
H-B-VAX II works by causing your body to produce its own protection by making disease-fighting
substances (antibodies) to fight the HBV. If a vaccinated person comes into contact
with Hepatitis B Virus (HBV), the body is usually ready, and produces antibodies to
destroy the virus. However, as with all vaccines, 100% protection against hepatitis
B cannot be guaranteed.
Because hepatitis B infection can go undetected for a long period of time, it is possible
that an individual may already be infected at the time the vaccine is given. The vaccine
may not prevent hepatitis B in these individuals.
2. What should I know before my child or I are given H-B-VAX II?
Warnings
Do not have H-B-VAX II if:
you or your child have an allergy to H-B-VAX II or any of the ingredients listed at
the end of this leaflet
you or your child have an allergy to yeast
the expiry date on the pack has passed.
If the vaccine is used after the expiry date has passed, it may not work.
Check with your doctor if
you are pregnant or intend to become pregnant
you are breast- feeding
you or your child have any medical conditions, especially the following
bleeding problems
severe heart or lung disease
diseases which decrease the immune system, for example, AIDS
H-B-VAX II may not work as well as it should if you or your child have diseases or
conditions which decrease the body's immune defence system. Your doctor will decide
whether or not to give the vaccine.
you or your child have an acute infection or high temperature
Your doctor may decide to delay your injection of H-B-VAX II.
you or your child are undergoing dialysis
You may need to be given a higher dose of H-B-VAX II than normal.
you or your child have any allergies to any other medicines or any other substances,
such as foods, preservatives, latex rubber or dyes
you or you child have previously been infected with hepatitis B virus
If you have not told your doctor about any of the above, tell them before you or your
child are given H-B-VAX II.
During treatment, you may be at risk of developing certain side effects. It is important
you understand these risks and how to monitor for them. See additional information
under Section
6. Are there any side effects?
Pregnancy and breastfeeding
Check with your doctor if you are pregnant or intend to become pregnant. It is not
known whether the vaccine is harmful to an unborn baby when administered to a pregnant
woman. Your doctor will give you H-B-VAX II only if it is clearly needed.
Talk to your doctor if you are breastfeeding or intend to breastfeed. It is not known
whether H-B-VAX II passes into breast milk. Your doctor will discuss the possible
risks and benefits of you being given H-B-VAX II while breast-feeding
Use in the elderly
Hepatitis B vaccines may not be as effective in individuals 65 years of age and older,
as they are with younger subjects.
3. What if my child or I are taking other medicines?
Tell your doctor, nurse, or pharmacist if you are taking any other medicines, including
any medicines, vitamins or supplements that you buy without a prescription from your
pharmacy, supermarket or health food shop.
H-B-VAX II may not work as well as it should if you or your child are taking medicines
that decrease the immune system, such as corticosteroids (e.g. prednisone) or cyclosporin.
Your doctor will advise you if you are taking any of these or other medicines that
decrease the immune system. Your doctor will decide whether or not to give the vaccine.
You may need to be given a higher dose of H-B-VAX II than normal.
Check with your doctor, nurse, or pharmacist if you are not sure about what medicines,
vitamins or supplements you are taking and if these affect H-B-VAX II.
4. How is H-B-VAX II given?
How much will you be given
Your doctor will decide on the dose of H-B-VAX II that you or your child will be given.
This depends on age and other factors, such as if you or your child are undergoing
dialysis.
How is it given
H-B-VAX II is given as an injection, usually into your upper arm muscle by a doctor
or trained nurse. For babies, the vaccine may be given into the upper thigh muscle.
For some people with bleeding problems, the vaccine may need to be given under the
skin (subcutaneously). The vaccine should not be injected directly into veins (intravenously).
When is it given
H-B-VAX II is generally given as a total of three doses over six months. Each dose
is given on a separate visit. The schedule is:
1st dose: at elected date
2nd dose: 1 month after first injection
3rd dose: 6 months after the first injection.
For children and teenagers aged 11 to 15 years, a total of two doses may be given
instead of three. The schedule for two doses is:
1st dose: at elected date
2nd dose: 4 to 6 months after the first injection.
Vaccination is not necessary in children or teenagers who have received a course of
hepatitis B vaccine before.
For babies born to mothers infected with HBV, the first dose of H-B-VAX II should
be given at birth, or as soon thereafter as possible. In addition to the H-B-VAX II,
an injection of hepatitis B immunoglobulin is also given.
It is important to return at the scheduled dates for the follow-up doses.
The duration of protective effect of H-B-VAX II is unknown. Therefore, it is not known
whether a booster dose will be necessary.
If you or your child miss a dose of H-B-VAX II
If you or your child miss a scheduled dose, talk to your doctor or nurse and arrange
another visit as soon as possible.
5. What should I know after my child or I have been given H-B-VAX II?
Things you should do
Keep your follow-up appointments with your doctor or clinic.
It is important to have your follow-up doses of H-B-VAX II at the appropriate times
to make sure the vaccine has the best chance of providing protection against the hepatitis
B virus.
Driving or using machines Be careful before you drive or use any machines or tools until you know how H-B-VAX
II affects you.
H-B-VAX II should not normally interfere with your ability to drive a car or operate
machinery. However, H-B-VAX II may cause dizziness or light-headedness in some people.
Make sure you know how you react to H-B-VAX II before you drive a car, operate machinery,
or do anything else that could be dangerous if you are dizzy or light-headed.
Looking after your medicine
It is unlikely that you will be asked to store H-B-VAX II. However if you need to
store H-B-VAX II:
Keep it where children cannot reach it.
Keep it in the refrigerator, but not in the door compartment.
Do not put H-B-VAX II in the freezer, as freezing destroys the vaccine.
Keep the injection in the original pack until it is time for it to be given.
Protect from light.
Getting rid of any unwanted medicine
If you no longer need to use this medicine or it is out of date, take it to any pharmacy
for safe disposal.
Do not use this medicine after the expiry date.
