Read all of this leaflet carefully before you are vaccinated because it contains important information for you.

Keep this leaflet. You may need to read it again.

  • If you have any further questions, ask your doctor, pharmacist or nurse.
  • This vaccine has been prescribed for you only. Do not pass it on to others.
  • If you get any side effects, talk to your doctor, pharmacist or nurse. This includes any possible side effects not listed in this leaflet. See section 4.

2. What you need to know before you use Avaxim
3. How to use Avaxim
4. Possible side effects
5. How to store Avaxim
6. Further information


Avaxim is a vaccine. Vaccines are used to protect you against infectious diseases. This vaccine helps to protect against hepatitis A infection in people 16 years of age and older. Hepatitis A infection is due to a virus that attacks the liver. It may be caught from food or drink that contains the virus. Symptoms include yellowing of the skin (jaundice) and feeling generally unwell.

When you are given an injection of Avaxim, your body's natural defenses will produce protection against hepatitis A infection.

Do not use Avaxim:
  • if you are allergic to:
    • the active ingredient or any ingredients of Avaxim (listed in section 6), or
    • neomycin, an antibiotic used during vaccine production, which may be present in the vaccine in small amounts, or
    • Avaxim,
  • if you are ill with a high temperature, the vaccination will be delayed until you have recovered.

Warnings and precautions

Talk to your doctor or nurse before using Avaxim, if you have:

  • liver disease.
  • a poor or weakened immune system due to:
    • corticosteroids, cytotoxic drugs, radiotherapy or other treatments that can weaken your immune system. Your doctor or nurse may wait until the treatment has finished.
    • HIV (human immunodeficiency virus) infection or any disease that weakens your immune system. It is recommended that you are given the vaccine, although it may not protect as well as it protects people with a normal immune system.
  • haemophilia or any other condition where you bruise or bleed more easily

Fainting can occur (mostly in adolescents) following, or even before, any needle injection. Therefore tell your doctor or nurse if you or your child fainted with a previous injection.

This vaccine will not protect you against other viruses that attack the liver (such as hepatitis B, hepatitis C or hepatitis E viruses).

If you already have the hepatitis A virus when you are given Avaxim, the vaccination may not work properly.

The vaccine cannot cause the infection against which it protects.

As with any vaccine, not everyone who receives Avaxim will definitely be protected against hepatitis A infection.

Receiving other vaccines or medicines

This vaccine can be given at the same time as any of the following, providing they are given in different parts of the body (for example another arm or leg) and are not mixed in the same syringe:

  • Typhoid polysaccharide vaccine
  • Yellow fever vaccine
  • Immunoglobulins (antibodies obtained from blood donors).

Avaxim may not work as well if it is given at the same time as immunoglobulins. However, it is likely that you will still be protected against hepatitis A infection.

Please tell your doctor, nurse or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.

Pregnancy and breast-feeding

If there is any chance you are pregnant, tell your doctor or nurse.

They will decide whether to delay the vaccination.

The use of this vaccine is possible during breast-feeding.

Driving and using machines

This vaccine is unlikely to have any affect on your ability to drive or use machines.

However, no studies on this have been performed.

Avaxim contains ethanol, phenylalanine, potassium and sodium

Avaxim contains 2 mg of alcohol (ethanol) in each 0.5 ml dose.

The small amount of alcohol in this medicine will not have any noticeable effects.

Avaxim contains 10 microgram phenylalanine in each 0.5ml dose which is equivalent to 0.17 microgram/kg for a 60 kg person. Phenylalanine may be harmful if you have phenylketonuria (PKU), a rare genetic disorder in which phenylalanine builds up because the body cannot remove it properly.

Avaxim contains less than 1mmol of potassium (39 mg) and sodium (23 mg) per dose, that is to say essentially 'potassium-free'and 'sodium-free'.


The vaccine will be given by a doctor or nurse who has been trained in the use of vaccines and who is equipped to deal with any uncommon severe allergic reaction to the injection.


Avaxim is given as an injection of half a millilitre of the vaccine to people 16 years of age and older.

You will be protected against hepatitis A about 14 days after you receive the first, single dose of Avaxim. This protection will last for up to 36 months.

If you need longer term protection against hepatitis A, you will need a second dose (booster) of an inactivated hepatitis A vaccine. This is usually given between 6 and 12 months after the first dose but can be given up to 36 months later. This booster will protect you against hepatitis A beyond 10 years.

Avaxim can be given as a booster if you received a different hepatitis A vaccine for your first dose (including vaccines that protect you against hepatitis A and typhoid fever).

How the vaccine is administered

The doctor or nurse will shake the syringe immediately before use and check that the liquid is white and cloudy, and that there are no unexpected particles in it.

Avaxim should be injected into a muscle in the upper outer part of your arm.

If you suffer from a bleeding disorder, you may be given the injection under the skin. The doctor or nurse must not inject the vaccine into the skin or into a blood vessel.

Avaxim will not be given into your buttock.


Like all medicines and vaccines, Avaxim can cause side effects, although not everybody gets them.

Serious allergic reactions

Serious or even life-threatening allergic reactions (anaphylactic reactions, including shock) can always happen, even if they are very rare. If you experience an allergic reaction, contact your doctor or healthcare professional immediately or go to the nearest hospital emergency room right away.

  • difficulty in breathing, blue colour of the tongue or lips,
