What is Relenza (Zanamivir) used for?

Relenza (Zanamivir) is a flu medication used to treat symptoms such as nasal congestion, coughing, fatigue, sore throat, or headaches. The medication prevents the reproduction of virus cells allowing the immune system to fight the infection naturally. Even though it may also be used to prevent infection caused by contact with those suffering from influenza, it is not a replacement for a vaccine. Your physician may prescribe it for other unlisted conditions, as well.

How should I use Relenza (Zanamivir)?

Follow your physician's instructions while using Relenza (Zanamivir) to get the safest and most effective results. Two inhalations are usually administered each day for five days when treating a flu infection. When preventing the flu, two inhalations may be taken once a day for a period of ten to twenty eight days. The best dosage and frequency of application will be determined by your physician based on your contact with the infection, your current health condition, and the severity of your symptoms. To administer the doses, load the blisters into the inhaler, remove the cap, press the button to puncture a blister, and inhale deeply with your mouth firmly sealed on the mouthpiece. If another dosage is required, wait at least two hours between each application. Ask your pharmacist or physician if you have any questions about using the inhaler or medication to ensure the correct usage.
