What Is Relenza?
Relenza (zanamivir) is a prescription medication used to manage influenza A and B infection. It works by inhibiting neuraminidase, an enzyme influenza viruses use to spread from infected cells to healthy ones, thereby limiting viral replication and reducing the duration of illness. With the right dose and ongoing monitoring, most patients experience meaningful symptom relief when treatment is started within 48 hours of symptom onset.

Is Online Relenza Treatment Right for You?
To qualify for a Relenza refill, you must have a confirmed or prior documented history of influenza for which zanamivir was previously prescribed, and your symptoms or recurrence must be consistent with your original diagnosis. Patients with reactive airway disease or chronic respiratory conditions such as asthma or COPD should discuss their history carefully, as Relenza carries a risk of bronchospasm in these populations and close physician review is required before a refill is issued.

Frequently asked questions
Relenza is an inhaled antiviral medication approved for the treatment of acute uncomplicated influenza A and B in patients who have been symptomatic for no more than 48 hours. It is also approved for prevention of influenza in certain situations.
Relenza is inhaled orally using a breath-activated Diskhaler device. The standard treatment dose is two inhalations of 5 mg each, twice daily for 5 days, for a total daily dose of 20 mg. Your physician will confirm the correct technique and dosing schedule for your situation.
Relenza is generally not recommended for patients with underlying airway disease such as asthma or COPD because it carries a risk of serious bronchospasm. If you have one of these conditions, your prescribing physician must weigh the risks carefully and a bronchodilator should be available during treatment.
Yes. Zanamivir is active against both influenza A and influenza B viruses by inhibiting the neuraminidase enzyme that both virus types require to replicate and spread within the respiratory tract.
For maximum effectiveness, Relenza should be started as soon as possible and ideally within 48 hours of the first appearance of flu symptoms such as fever, body aches, or cough. Starting treatment after this window is generally less effective.
Common side effects reported with Relenza include diarrhea, nausea, nasal signs and symptoms, bronchitis, cough, headache, and dizziness. Serious but rare reactions include bronchospasm and allergic reactions. Contact your provider if you experience difficulty breathing after inhalation.
