Generic name:

Pharmacist-reviewed drug information from the RxWiki encyclopedia.

Overview

Fluvirin is a vaccine to help protect against the influenza virus in adults and children aged four years and over. Fluvirin is an inactivated vaccine that cannot cause "the flu" but stimulates the immune system to produce antibodies that protect against it. The full effect of the vaccine is generally achieved approximately 3 weeks after vaccination.

Fluvirin is available in an injectable form to be given directly into the muscle by a healthcare professional. 

Common side effects include mild hypersensitivity reactions such as rash, local reactions at the injection site, and influenza-like symptoms such as fever, muscle aches, tiredness, headache, chills. These reactions are due to the immune system responding to the vaccine and are not flu. They usually disappear within one to two days without treatment.

What is it used for?

Fluvirin is an inactivated influenza virus vaccine for persons 4 years of age and older against influenza virus disease caused by influenza virus.

Fluvirin is not indicated for children less than 4 years of age because there is evidence of diminished immune response in this age group.

This vaccine may be prescribed for other uses. Ask your doctor or pharmacist for more information.

How to take it

Children aged four to less than nine years who have not previously been vaccinated against flu should be given a second dose of the vaccine at least four weeks after their first vaccination.

Children who have previously had a flu vaccine only need one dose.

For adults and older children the vaccine is usually given as a single injection into the muscle of the upper arm.

Warnings

Serious side effects have been reported with Fluvirin, including the following:

  • Guillain-Barré Syndrome (GBS). Tell your healthcare provider immediately if you have a history of GBS or any neurologic disorder including seizures. If Guillain-Barré syndrome has occurred within 6 weeks of receiving an influenza vaccine in the past, your doctor will determine if you should receive Fluvirin.
  • Altered Immunity. Tell your healthcare provider immediately if you have a suppressed immune system due to a current condition or medication therapy. If Fluvirin is administered to a person with a suppressed immune system, including individuals receiving immunosuppressive therapy, you may not get the best immune response. Tell your doctor if you are receiving immunosuppressive therapies such as prednisone, auto-Immune treatments such as etanercept (Enbrel), and chemotherapy such as capecitabine (Xeloda).

    • Swelling of the face, tongue, or throat
    • Trouble breathing
    • Hives or bad rash

Pregnancy

Tell your doctor if you are pregnant or plan to become pregnant.

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

Fluvirin falls into category C. There are no well-controlled studies that have been done in pregnant women. Fluvirin should be used during pregnancy only if the possible benefit outweighs the possible risk to the unborn baby.

Breastfeeding

Tell your doctor if you are breastfeeding or plan to breastfeed.

It is not known if Fluvirin crosses into human milk. Because many medications can cross into human milk and because of the possibility for serious adverse reactions in nursing infants with use of this medication, a choice should be made whether to stop nursing or stop the use of this medication. Your doctor and you will decide if the benefits outweigh the risk of using Fluvirin.
