Tamiflu: How it works

Tamiflu is used to treat or help prevent influenza (the flu) in certain adults and children. The flu is a sickness caused by the influenza virus. For more information about this condition and how the drug is used, see the “Tamiflu: Uses” section above.

Tamiflu’s mechanism of action (how it works) is to block a certain protein found on the influenza virus. This protein is responsible for releasing particles of the flu virus into your body.

By blocking this protein, Tamiflu keeps the virus from making copies of itself. This process helps keep the influenza virus from spreading in your body. 

How long does Tamiflu take to start working?

Tamiflu starts working right away to treat or help prevent the flu. If you’re having flu symptoms, they should start easing within a couple of days.

Tamiflu: Taking while pregnant

It isn’t known whether Tamiflu is safe to take during pregnancy. The drug has not been tested in enough clinical studies in pregnancy to know for certain.

In general, the Centers for Disease Control and Prevention (CDC) considers Tamiflu to be safe and effective for use during pregnancy.

If you’re pregnant or planning a pregnancy, talk with your doctor before taking Tamiflu.

Tamiflu and birth control needs

Doctors aren’t certain whether it’s safe to take Tamiflu during pregnancy. Talk with your doctor about your birth control needs with Tamiflu if you’re sexually active and you or your partner can become pregnant. Your doctor can recommend whether you should use birth control with this medication.

Tamiflu: Taking while breastfeeding

Tamiflu passes into breast milk. However, it’s not known whether the drug causes side effects in a breastfed child.

If you’re breastfeeding or planning to do so, talk with your doctor. They can explain the risks and benefits of taking Tamiflu while breastfeeding.

Tamiflu: Questions you may have

Here are some common questions about Tamiflu and brief answers to them. If you’d like to know more about these topics, ask your doctor.

Is Tamiflu an antibiotic?

No, Tamiflu is not an antibiotic. Antibiotics are used to treat infections caused by bacteria.

Instead, Tamiflu is an antiviral. It’s used to treat or help prevent sickness caused by the influenza virus. Tamiflu is not effective against bacterial infections.

Should I still get a flu vaccine if I take Tamiflu?

Yes, if your doctor tells you it’s safe, you can still get certain types of flu vaccines while taking Tamiflu.

Injectable forms of the flu vaccine contain an inactive (dead) version of the flu virus. You may be able to get this version of the flu vaccine while taking Tamiflu.

However, you should not get the nasal spray flu vaccine (FluMist) while taking Tamiflu. It’s possible that Tamiflu could make this vaccine less effective. For this reason, you should not get the FluMist vaccine in the 2 weeks before starting Tamiflu treatment. And you should not get FluMist during Tamiflu treatment or for at least 48 hours after your last dose of the drug.

If you have questions about getting a flu vaccine while taking Tamiflu, talk with your doctor.

Besides taking Tamiflu, how can I help prevent the flu?

Below are a few ways to lower your risk of getting the flu:

  • Get a yearly flu vaccine.
  • Do not touch your eyes, nose, or mouth with unwashed hands.
  • Cover your mouth and nose with a tissue when sneezing or coughing. Immediately throw away the tissue and wash your hands. If a tissue is not available, use the corner of your elbow instead.
  • Wash your hands frequently for at least 20 seconds with warm water and soap. If you’re unable to wash your hands, use an alcohol-based sanitizer.
