1. What is Engerix-B and what is it used for

Engerix-B is a vaccine that is used to protect against hepatitis B infection. It may also help protect against hepatitis D infection.

This vaccine can be given to adults and adolescents from 16 years of age. In exceptional circumstances, it may also be given to children and adolescents between 11 and 15 years of age (see section 3).

Hepatitis B is an infectious disease of the liver caused by a virus. Some people have the hepatitis B virus in their body but cannot get rid of it. These people can continue to infect others and are known as carriers. The spread of the disease occurs when the virus enters the body after contact with bodily fluids, almost always blood, from an infected person.

If a mother is a carrier of the virus, she can pass the virus to her child during birth. It is also possible to contract the virus from a carrier through, for example, unprotected sex, sharing injectable syringes, or treatment with medical equipment that has not been properly sterilized.

The main signs of the disease include: headache, fever, malaise (nausea) and jaundice (the skin and eyes turn yellow), although in about three out of 10 patients there are no signs of disease. Of those infected with hepatitis B, one in 10 adults and up to nine in 10 children will become carriers of the virus and are likely to develop severe liver damage and in some cases liver cancer.

How Engerix-B works

Engerix-B contains a small amount of the outer surface of the hepatitis B virus. This outer surface is not infectious and cannot cause the disease.

  • When you receive the vaccine, it will stimulate your body's immune system to prepare it to protect itself against these viruses in the future.
  • Engerix-B will not protect you if you have already contracted the hepatitis B virus.
  • Engerix-B can only help protect you against hepatitis B virus infection.

2. What you need to know before you receive Engerix-B

Do not receive Engerix-B:

  • If you are allergic (hypersensitive) to Engerix-B or any of the other components of this vaccine (listed in section 6).
  • If you have a high temperature (fever).

Engerix-B should not be administered if any of the above applies to you. If you are not sure, talk to your doctor or pharmacist before receiving Engerix-B. Inform your doctor or pharmacist if you have any allergies or if you have ever had health problems after receiving a vaccine.

Warnings and precautions

Talk to your doctor or pharmacist before receiving Engerix-B if:

  • You are on dialysis for a kidney problem or if you have a disease that may affect your immune system.

People who need dialysis, who have chronic liver problems, who are hepatitis C carriers, or who are HIV positive can also receive Engerix-B. This is because hepatitis B infections can be severe in these patients. You will find more information about kidney problems and dialysis in Section 3.

If you are not sure if any of the above applies to you, talk to your doctor before receiving Engerix-B.

Fainting (syncope) may occur after any injection, especially in adolescents. You should inform your doctor or nurse if you or your child have fainted after a previous injection.

Like other vaccines, Engerix-B may not fully protect you against hepatitis B. A number of factors such as advanced age, sex, overweight, smoking, and some chronic problems reduce the immune response to the vaccine. If any of these apply to you, your doctor may decide to perform a blood test or administer additional doses of Engerix-B to ensure you are protected.

Other medicines and Engerix-B

Tell your doctor or pharmacist if you are using, have recently used, or might use any other medicines.

Engerix-B can be administered at the same time as most usual vaccines. Your doctor will make sure that the vaccines are injected separately and in different parts of the body.

Pregnancy and breastfeeding

  • If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medicine.

Driving and using machines

It is unlikely that Engerix-B will affect your ability to drive or use machines. However, do not drive or use machines if you feel unwell.

Engerix-B contains sodium

This vaccine contains less than 23 mg of sodium (1 mmol) per dose; this is essentially "sodium-free".

3. How Engerix-B is administered

How your vaccine is administered

Your doctor will administer the recommended dose of Engerix-B.

Engerix-B will be administered:

  • as an injection into the muscle of the upper arm
  • as an injection under the skin if you bruise easily or have bleeding problems.

How much is administered

You will receive a series of Engerix-B injections. Once you have completed the injection schedule, you can expect long-term protection against hepatitis B.

Adults and adolescents from 16 years of age will receive the 20 micrograms/1 ml vaccine.

There are several alternatives for administering Engerix-B. Your doctor will choose the most suitable schedule for you:

Schedule 1 – for adults or adolescents from 16 years of age

First injection - now

Second injection - 1 month after the first injection

Third injection - 6 months after the first injection

Schedule 2 – for adults or adolescents from 16 years of age

First injection - now

Second injection - 1 month after the first injection

Third injection - 2 months after the first injection

Fourth injection - 12 months after the first injection

  • This schedule can also be used if you are being vaccinated due to recent exposure to hepatitis B, as it will provide faster protection.

Schedule 3 – only for adults (from 18 years of age)

This schedule will only be administered in exceptional circumstances, for example, if you need to travel to a high-risk area within one month of being vaccinated.

First injection - now

Second injection - 1 week after the first injection

Third injection - 3 weeks after the first injection

Fourth injection - 12 months after the first injection

Schedule 4 – only for children and adolescents between 11 and 15 years of age

This schedule is only used if there is doubt that the child will receive the third injection. For this schedule, Engerix-B (20 micrograms/1 ml) will be used. This will provide a higher level of protection than two doses of Engerix-B Junior (10 micrograms/0.5 ml).

First injection - now

Second injection - 6 months after the first injection

  • When using this schedule, protection may not be achieved until after the second dose. This two-dose schedule is only used when there is a relatively low risk of hepatitis B infection during the vaccination schedule and when completion of the schedule can be ensured.

It is very important that you attend your injections at the recommended intervals. If you have any questions about the amount of vaccine you will receive, consult your doctor.

Kidney problems and dialysis

  • People from 16 years of age

If you have a kidney problem or are on dialysis, your doctor may decide to vaccinate you with four double doses (2 x 20 micrograms/1 ml) of vaccine at 0, 1, 2, and 6 months. Your doctor may also decide to perform a blood test to ensure you are protected against hepatitis B.
