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 an influenza treatment medication available by prescription and taken as a breathable powder that disables the flu virus and makes it unable to spread throughout the body. The Relenza generic name is Zanamivir, and this antiviral drug aids in users overcoming the flu more quickly or preventing the onset of flu if taken at first sign of getting the virus. The Relenza Diskhaler is similar in constituency and function to Tamiflu, and for some people the breathable Relenza medication begins to work faster and suppresses flu more effectively than Tamiflu.

Standard dosage for the Relenza Diskhaler is Relenza 10mg, taken by inhaling Relenza 5mg puffs once or 2x or day depending on what's shown in your prescription. Taking puffs after eating food is recommended.

Relenza is best when taken within 48 hours of flu symptoms starting to come on.


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


Let your doctor know 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 immediately every time a dose is loaded into the Relenza Diskhaler. Doses left in the inhaler after being loaded will spoil and cannot be inhaled for effective treatment.

Maximum dosage guidelines of 2 doses inhaled per day are not to be exceeded.

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. Waiting at least 48 hours after your last dose of Relenza before getting any nasal version of the flu vaccine is important.


There are no known negative drug interaction risks between Relenza and other Rx or OTC medications, but it is always best to let your doctor know of all medications you are currently taking before getting a prescription and going to buy the Relenza Diskhaler online.

Side Effects

Relenza side effects may occur, and some users may have cough, diarrhea, ear, nose, or throat infection, headache, nausea and vomiting, sinusitis, dizziness, fever or chill, or joint problems. If Relenza side effects do occur it may be best to discontinue use and meet with your doctor again to discuss common flu relief medicated inhaler alternatives.
