  • Summary of Relenza vs. Rimantadine

    Summary for Antiviral
    Prescription only

    Relenza (zanamivir) is an antiviral medication. It can help ease flu symptoms and prevent the flu in certain adults and children. But it doesn't replace the seasonal flu vaccine. Relenza (zanamivir) comes as an inhaler that's inhaled by mouth twice daily for flu treatment or once daily for flu prevention. Because of the rare risk of bronchospasm, people who have asthma or chronic obstructive pulmonary disease (COPD) aren't recommended to use this medication. Common side effects include runny nose and dizziness. Relenza (zanamivir) is brand name only and not available as a generic medication.

    Summary for Antiviral
    Prescription only

    Rimantadine is an antiviral used to treat influenza A in adults, and prevent influenza A in children and adults. But rimantadine hasn't been a recommended option in recent years because many strains of flu virus have become resistant to this medication. Rimantadine is taken by mouth, typically twice a day. Side effects aren't common, but can include nausea, trouble sleeping, and dizziness. The brand name Flumadine has been discontinued so it's only available as a generic.
