What is Fluarix Quadrivalent?

Fluarix Quadrivalent is an inactivated influenza virus vaccine used for the prevention of influenza.

Influenza virus (commonly known as "the flu") is a serious disease caused by a virus. Influenza virus can spread from one person to another through small droplets of saliva that are expelled into the air when an infected person coughs or sneezes. The virus can also be passed through contact with objects the infected person has touched, such as a door handle or other surfaces.

Fluarix Quadrivalent is used to prevent infection caused by influenza virus. The vaccine is redeveloped each year to contain specific strains of inactivated (killed) flu virus that are recommended by public health officials for that year.

The injectable Fluarix Quadrivalent (flu shot) is a "killed virus" vaccine.

Fluarix Quadrivalent works by exposing you to a small dose of the virus, which helps your body to develop immunity to the disease. This medicine will not treat an active infection that has already developed in the body.

Fluarix Quadrivalent is for use in adults and children who are at least 6 months old.

Becoming infected with influenza is much more dangerous to your health than receiving this vaccine. Influenza causes thousands of deaths each year, and hundreds of thousands of hospitalizations. However, like any medicine, this vaccine can cause side effects but the risk of serious side effects is extremely low.

Like any vaccine, Fluarix Quadrivalent may not provide protection from disease in every person. This vaccine will not prevent illness caused by avian flu ("bird flu").

Warnings

The injectable Fluarix Quadrivalent (flu shot) is a "killed virus" vaccine.

Becoming infected with influenza is much more dangerous to your health than receiving this vaccine. However, like any medicine, this vaccine can cause side effects but the risk of serious side effects is extremely low.

Before taking this medicine

You may not be able to receive this vaccine if you are allergic to eggs, or if you have:

  • a history of severe allergic reaction to a flu vaccine; or
  • a history of Guillain-Barre syndrome (within 6 weeks after receiving a flu vaccine).

Tell your doctor if you have ever had:

  • bleeding problems;
  • a neurologic disorder or disease affecting the brain (or if this was a reaction to a previous vaccine);
  • seizures;
  • a weak immune system caused by disease, bone marrow transplant, or by using certain medicines or receiving cancer treatments; or
  • an allergy to latex.

You can still receive a vaccine if you have a minor cold. If you have a severe illness with a fever or any type of infection, wait until you get better before receiving this vaccine.

The Centers for Disease Control and Prevention recommends that pregnant women get a flu shot during any trimester of pregnancy to protect themselves and their newborn babies from flu. The nasal spray form of influenza vaccine is not recommended for use in pregnant women.

It may not be safe to breastfeed while using Fluarix Quadrivalent. Ask your doctor about any risk.

This vaccine should not be given to a child younger than 6 months old.

Influenza virus injectable vaccine side effects

Get emergency medical help if you have signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

You should not receive a booster vaccine if you had a life-threatening allergic reaction after the first shot.

Keep track of any and all side effects you have after receiving this vaccine. If you ever need to receive Fluarix Quadrivalent in the future, you will need to tell your doctor if the previous shot caused any side effects.

Influenza virus injectable (killed virus) vaccine will not cause you to become ill with the flu virus that it contains. However, you may have flu-like symptoms at any time during flu season that may be caused by other strains of influenza virus.

Call your doctor at once if you have:

  • a light-headed feeling, like you might pass out;
  • severe weakness or unusual feeling in your arms and legs (may occur 2 to 4 weeks after you receive the vaccine);
  • high fever;
  • seizure (convulsions); or
  • unusual bleeding.

Common side effects may include:

  • low fever, chills;
  • mild fussiness or crying;
  • redness, bruising, pain, swelling, or a lump where the vaccine was injected;
  • headache, tired feeling; or
  • joint or muscle pain.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report vaccine side effects to the US Department of Health and Human Services at 1-800-822-7967.

How is this vaccine given?

This vaccine is given as an injection (shot) into a muscle. You will receive this injection in a doctor's office or other clinic setting.

You should receive a flu vaccine every year. Your immunity will gradually decrease over the 12 months after you receive the Fluarix Quadrivalent. Children receiving this vaccine may need a booster shot one month after receiving the first vaccine.

The Fluarix Quadrivalent is usually given in October or November. Some people may need to have their vaccines earlier or later. Follow your doctor's instructions.

Your doctor may recommend treating fever and pain with an aspirin-free pain reliever such as acetaminophen (Tylenol) or ibuprofen (Motrin, Advil, and others) when the shot is given and for the next 24 hours. Follow the label directions or your doctor's instructions about how much of this medicine to give your child.

It is especially important to prevent fever from occurring in a child who has a seizure disorder such as epilepsy.

What happens if I miss a dose?

Since flu shots are usually given only one time per year, you will most likely not be on a dosing schedule. Call your doctor if you forget to receive your yearly flu shot in October or November.

If your child misses a booster dose of this vaccine, call your doctor for instructions.

What happens if I overdose?

An overdose of this vaccine is unlikely to occur.

Follow your doctor's instructions about any restrictions on food, beverages, or activity.

What other drugs will affect influenza virus injectable vaccine?

If you are using any of these medications, you may not be able to receive the vaccine, or may need to wait until the other treatments are finished:

  • phenytoin, theophylline, or warfarin (Coumadin, Jantoven);
  • an oral, nasal, inhaled, or injectable steroid medicine;
  • medications to treat psoriasis, rheumatoid arthritis, or other autoimmune disorders--azathioprine, etanercept, leflunomide, and others; or
  • medicines to treat or prevent organ transplant rejection--basiliximab, cyclosporine, muromonab-CD3, mycophenolate mofetil, sirolimus, tacrolimus.

This list is not complete. Other drugs may affect Fluarix Quadrivalent, including prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible drug interactions are listed here.

Flu Vaccines and Egg Allergy: Which Are Safe?

How well does the flu vaccine work?
Flu vaccination typically reduces the risk of flu illness by between 40% and 60% during seasons when the flu viruses are well-matched to the flu vaccine. But if you are infected with the virus, the vaccine reduces your chances of getting the flu and passing it on to others and lessens the severity of symptoms, hospitalizations and death.
