What is a Generic Drug?

A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.

The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.

Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.


Relenza is a prescription influenza medication for flu treatment and given as a breathable powder that suppresses the flu virus and prevents it spreading in the body. The Relenza generic name is Zanamivir, and this antiviral drug is proven effective for helping users overcome the flu more quickly or stop the flu from onsetting if administered at first sign of coming down with the virus. The Relenza Diskhaler is similar to Tamiflu for constituency and function, but for some people the inhaled medication works faster and more effectively in comparison to Tamiflu.


Standard dosage for the Relenza Diskhaler is Relenza 10mg, taken by inhaling Relenza 5mg puffs 1x or twice or day depending on the individual's prescription. After eating is the best time to take an inhalation.

Relenza should be taken within 48 hours of flu symptoms beginning.


The active ingredient in Relenza is Zanamivir (Relenza generic name).


Inform your doctor of any history of COPD, chronic bronchospasms or other lung health conditions, diabetes, or heart conditions before starting on Relenza.

Medication must always be taken right away following a dose being loaded into the Relenza Diskhaler. Leaving doses loaded into inhaler but not taken will result in spoiled doses that cannot be inhaled for effective treatment.

Do not exceed dosage guidelines of 2 doses inhaled per day maximum.

Relenza should not be taken longer than 5 days if taken at the standard 2x daily dosage.

Using Relenza can make flu vaccines less effective. Be sure to wait at least 48 hours after your last dose of Relenza before getting any nasal version of the flu vaccine.


Negative drug interaction risks between Relenza and other Rx or OTC medications have not been established, but it is always best to inform your doctor of all medications you are currently taking before getting a prescription and proceeding to buy Relenza Diskhaler online.

Side Effects

Relenza side effects are a possibility, and some users may experience cough, diarrhea, ear, nose, or throat infection, headache, nausea and vomiting, sinusitis, dizziness, fever or chill, or joint problems. If Relenza side effects are seen you may want to stop use and speak with your doctor again regarding common flu relief medicated inhaler options.
