1. What is Fluarix and what is it used for

Fluarix is a vaccine to prevent influenza in adults and children from 6 months of age.

Influenza is a disease of the upper respiratory tract and lungs caused by an influenza virus infection. The most common symptoms of influenza are: high fever, sore throat, cough, general aches, headache, weakness, and fatigue. Complications can occur, especially in very young, very old people, and those with low immunity to infections.

How does Fluarix work?

• Fluarix contains killed viruses that cannot cause influenza.
• Fluarix stimulates the body's immune system to produce antibodies against the specific viruses the vaccine is designed to protect against. This will help prevent the disease.
• The vaccine is targeted against influenza viruses according to official recommendations.
• As with all vaccines, it is possible that Fluarix may not completely protect all vaccinated individuals.

2. What you need to know before you receive Fluarix

Do not receiveFluarix if:

• you are allergic to the active substances or any of the other components of this vaccine (listed in section 6) or to any component that may be present in very small amounts, such as ovalbumin (an egg protein), hydrocortisone, gentamicin sulfate, formaldehyde, and sodium deoxycholate.

Warnings and precautions

Talk to your doctor, pharmacist, or nurse before receiving Fluarix if:

• you have a severe infection with high fever. If this happens, vaccination may need to be postponed until you feel better. A minor infection, such as a cold, should not be a problem, but talk to your doctor, pharmacist, or nurse first.

• you have a bleeding problem or bruise easily.

Fainting (syncope) can occur following, or even before, any injection, especially in adolescents. Tell your doctor, pharmacist, or nurse if you have fainted with a previous injection.

People with weakened immune systems, for example due to HIV infection or due to medicines that suppress the immune system, may not get the full benefit of Fluarix.

If any of the above applies to you (or you are not sure), talk to your doctor, pharmacist, or nurse before receiving Fluarix.

Other medicines and vaccines and Fluarix

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

If Fluarix is to be given at the same time as other vaccines, a different injection site should be used for each type of vaccine.

Pregnancy, breastfeeding and fertility

If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before receiving this vaccine.

Driving and using machines

Some of the effects mentioned below in section 4 “Possible side effects” (e.g. fatigue or dizziness) may temporarily affect your ability to drive or use machines. Do not drive or use machines or tools if you do not feel well.

Fluarix contains sodium

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

Fluarix contains potassium

This medicine contains less than 39 mg (1 mmol) of potassium per dose, and is therefore considered to be “potassium-free”.

Fluarix contains polysorbate 80

This medicine does not contain more than 0.415 mg of polysorbate 80 per dose. Polysorbates may cause allergic reactions. Tell your doctor if you have any known allergy to this substance.

3. How Fluarix is administered

Fluarix is given as a single injection of 0.5 ml into a muscle.

Use in children

Children under 9 years of age who have not been previously vaccinated against influenza will receive a second injection at least one month after the first. Make sure your child completes the vaccination course. This will maximize the protection provided by Fluarix.

If you have any other questions about the use of this medicine, ask your doctor, pharmacist, or nurse.

4. Possible side effects

Like all medicines, this vaccine can cause side effects, although not everybody gets them.

Talk to your doctor, pharmacist, or nurse if you want more information on the possible side effects of Fluarix.
