FluLaval is a brand of influenza virus vaccine (injectable).
FluLaval (influenza virus vaccine) 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.
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.
FluLaval vaccine (flu shot) is a "killed virus" vaccine. FluLaval works by exposing you to a small dose of the virus, which helps your body to develop immunity to the disease. FluLaval vaccine will not treat an active infection that has already developed in the body.
FluLaval is for use in adults 18 years of age and older. FluLaval is not indicated for use in children.
Becoming infected with influenza is much more dangerous to your health than receiving FluLaval vaccine. Influenza causes thousands of deaths each year, and hundreds of thousands of hospitalizations. However, like any medicine, FluLaval can cause side effects but the risk of serious side effects is extremely low.
Like any vaccine, FluLaval may not provide protection from disease in every person. FluLaval will not prevent illness caused by avian flu ("bird flu").
Important information
The injectable FluLaval (flu shot) is a "killed virus" vaccine. Influenza virus vaccine is also available in a nasal spray form, which is a "live virus" vaccine. This medication guide addresses only the injectable form of this vaccine.
You can still receive a vaccine if you have a minor cold. In the case of a more severe illness with a fever or any type of infection, wait until you get better before receiving FluLaval.
Keep track of any and all side effects you have after receiving FluLaval. If you ever need to receive FluLaval in the future, you will need to tell your doctor if the previous shot caused any side effects.
Like any vaccine, FluLaval may not provide protection from disease in every person. FluLaval will not prevent illness caused by avian flu ("bird flu").
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.

a neurologic disorder or disease affecting the brain (or if this was a reaction to a previous vaccine);

Vaccines may be harmful to an unborn baby and generally should not be given to a pregnant woman. However, not vaccinating the mother could be more harmful to the baby if the mother becomes infected with a disease that FluLaval could prevent. Your doctor will decide whether you should receive FluLaval, especially if you have a high risk of infection with influenza. It is not known whether influenza virus vaccine passes into breast milk or if it could harm a nursing baby. Do not receive FluLaval without telling your doctor if you are breast-feeding a baby. FluLaval should not be given to a person younger than 18 years of age.
How is FluLaval given?
FluLaval 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 FluLaval.
The FluLaval 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.
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. Some people may need to have their vaccines earlier or later. Follow your doctor"s instructions.
What happens if I overdose?
An overdose of FluLaval is unlikely to occur.
What should I avoid?
Follow your doctor"s instructions about any restrictions on food, beverages, or activity.
