1. What is Fluarix and what is it used for
Fluarix is a vaccine intended for use in adults and children from 6 months of age to prevent influenza.
Influenza is a disease of the upper respiratory tract and lungs caused by the influenza virus. The most common symptoms of influenza are high temperature, sore throat, cough, general aches and pains, headache, weakness, and fatigue. Post-influenza complications can occur, especially in very young, older, and immunocompromised individuals.
How does Fluarix work?
- Fluarix contains killed viruses that cannot cause influenza.
- Fluarix stimulates the immune system of the vaccinated person to produce antibodies against the specific viruses the vaccine is designed to protect against, which helps prevent the disease.
- The vaccine has been developed against influenza viruses based on official recommendations.
- Like all vaccines, Fluarix may not fully protect all vaccinated individuals.
2. Important information before using Fluarix
When not to use Fluarix:
- If the patient is allergic to the active substances or any of the other ingredients of this vaccine (listed in section 6) or to any ingredient that may be present in very small amounts, such as egg albumen (ovalbumin), hydrocortisone, gentamicin sulfate, formaldehyde, and sodium deoxycholate.
Warnings and precautions:
Before administering Fluarix, discuss with your doctor, pharmacist, or nurse:
- if the patient has an acute infection with high fever. Vaccination should be postponed until the patient feels better. Mild infection, such as a cold, is not a contraindication to vaccination, but discuss with your doctor, pharmacist, or nurse beforehand.
- if the patient has bleeding problems or a tendency to bruise.
After or even before administration of each injection, fainting (especially in adolescents) may occur. Inform your doctor, pharmacist, or nurse if the patient has fainted during injection in the past.
If the patient has weakened immune systems, e.g., due to HIV infection or immunosuppressive therapy, Fluarix may not be fully effective.
Tell your doctor, pharmacist, or nurse if any of the above applies to the person to be vaccinated or if the patient is unsure.

Tell your doctor, pharmacist, or nurse about all medicines being taken now or recently, and any medicines planned to be taken.
