Antivirals for Influenza
Influenza (Flu) Treatment with Relenza – Redwood Pharmacy
Seasonal influenza (flu) is a highly contagious respiratory infection that can cause sudden fever, fatigue, muscle aches, sore throat, and cough. While most people recover within a week, flu can lead to serious complications—especially in vulnerable groups like the elderly, those with chronic conditions, and pregnant women.
At Redwood Pharmacy, we offer antiviral treatment with Relenza (zanamivir) for eligible patients, helping to shorten the duration of symptoms and reduce the risk of complications if started early.
๐ค What Is Influenza (Flu)?
Flu is caused by influenza viruses that spread through coughing, sneezing, or contact with contaminated surfaces. It typically causes more severe symptoms than a common cold.
Common symptoms include:
-
Sudden high fever
-
Chills and sweating
-
Cough (usually dry)
-
Sore throat
-
Muscle aches and headaches
-
Fatigue or weakness
-
Nasal congestion
Flu can come on very suddenly and leave you feeling exhausted for several days.
๐ What Is Relenza (Zanamivir)?
Relenza is an antiviral medicine used to treat influenza A and B infections. It belongs to a class of drugs called neuraminidase inhibitors and works by blocking the virus’s ability to spread inside your body.
โ Benefits of Relenza:
-
Helps reduce the length of flu symptoms by 1–2 days when started early
-
May reduce the risk of flu-related complications
-
Works best if taken within 48 hours of symptom onset
Relenza is not a cure, but it may help your body recover faster and lessen the severity of illness.
๐ซ How Is Relenza Taken?
Relenza is administered via an inhaler device, similar to an asthma inhaler.
Typical dosing:
-
2 inhalations twice daily for 5 days
-
Treatment should begin within 48 hours of the first symptoms
Relenza is not suitable for patients with severe asthma or COPD unless assessed and approved by a clinician due to the risk of bronchospasm.
โ ๏ธ Who Can Use Relenza?
Relenza may be offered to:
-
Adults and children over the age of 5
-
Patients who are otherwise healthy but caught flu early
-
High-risk individuals (e.g. immunocompromised or elderly)
-
Those unable to take oral antivirals (like oseltamivir)
It is not a substitute for the annual flu vaccine, which is the best prevention method.
