1. WHAT AVAXIM IS AND WHAT IT IS USED FOR
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.
2. WHAT YOU NEED TO KNOW BEFORE YOU USE AVAXIM
Do not use Avaxim:
Warnings and precautions
Talk to your doctor or nurse before using Avaxim, if you have:
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:
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 small amounts of ethanol (alcohol), less than 100 mg per dose.
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’.
3. HOW TO USE AVAXIM
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.
4. POSSIBLE SIDE EFFECTS
Like all medicines and vaccines, Avaxim can cause side effects, although not everybody gets them.
Possible serious allergic reactions
Serious allergic reactions are always a very rare possibility after receiving a vaccine. These reactions may include:
If serious allergic reactions occur, they often do so very soon after the injection while still in the clinic or doctor’s surgery. If any of these symptoms occur after leaving the place where your injection was given, you must consult a doctor IMMEDIATELY.
