Zanamivir Drug Information
Available by prescription only, zanamivir (Relenza®) is a medication approved for the following uses:
- Preventing the flu (such as during flu outbreaks)
- Treating the flu to help shorten the duration of symptoms.
Unlike other flu medications, zanamivir is inhaled. Therefore, it may not be recommended for people with certain lung diseases. Zanamivir is inhaled into the lungs either once or twice a day, depending on several factors. If you are using it twice a day, try to space the doses evenly (every 12 hours). If you take it once a day, try to take it at the same time each day.
Prior to beginning treatment with zanamivir, inform your healthcare provider about all other medical conditions you have and any other drugs you are taking. If you are a woman, tell your healthcare provider if you are pregnant or breastfeeding.
