Additional Information

Why is this medication prescribed

Zanamivir is used to treat some types of influenza (flu) in patients 12 years and older who have had symptoms of the flu for 2 days or less. Zanamivir is in a class of drugs called neuraminidase inhibitors. These drugs work by stopping the growth and spread of the flu virus in your body. Zanamivir helps shorten the time you have flu symptoms such as nasal congestion, sore throat, cough, muscle aches, tiredness, headache, fever, and chills.

What other information should I know

Zanamivir will not stop you from giving the flu to others. You should maintain proper hygiene, wash your hands frequently, and avoid situations such as sharing cups and utensils that can spread the virus to others.

Zanamivir does not replace the flu vaccine. You should continue to receive a flu shot each year if your doctor recommends it.

The Diskhaler should only be used for zanamivir. Do not use the Diskhaler to take other medications that you inhale.

Do not let anyone else take your medication. Your prescription is probably not refillable. If you still have symptoms of the flu after you finish the zanamivir, call your doctor.
