What is Fluvir (Oseltamivir)?

Fluvir (Oseltamivir) is an antiviral medication used to treat and prevent influenza (flu) caused by influenza virus types A and B. It belongs to a class of drugs known as neuraminidase inhibitors, which stop the spread of the flu virus inside the body. Fluvir is most effective when started within the first 48 hours of flu symptoms and can also be prescribed for post-exposure prevention among close contacts, such as family members of infected individuals.

Benefits

Fluvir (Oseltamivir) offers proven effectiveness in reducing flu symptoms, duration, and transmission. Major benefits include:

• Reduces the duration and severity of influenza symptoms when taken early.
• Helps prevent flu infection in individuals exposed to the virus.
• Lowers the risk of flu-related complications such as bronchitis, pneumonia, and hospitalization.
• Suitable for use in both adults and children (as prescribed by a physician).
• Well tolerated with minimal gastrointestinal or neurological effects compared to other antivirals.

Dosage & Usage

Fluvir (Oseltamivir) is available in 75mg capsules. The dosage depends on whether it is used for treatment or prevention:

• Treatment of Influenza: 75mg taken twice daily for 5 days. For best results, start treatment within 48 hours of symptom onset.
• Prevention (Post-Exposure): 75mg taken once daily for 10 days following exposure to an infected person.
• Seasonal Prevention: In certain high-risk cases, your healthcare provider may recommend 75mg daily for up to 6 weeks during flu season.

Fluvir can be taken with or without food. Taking it with meals may reduce the risk of stomach upset. Always follow your doctor’s dosing instructions exactly and complete the full course even if you feel better.

How It Works

Oseltamivir, the active ingredient in Fluvir, works by selectively inhibiting the viral neuraminidase enzyme found on the surface of the influenza virus. This enzyme plays a crucial role in the release of new viral particles from infected cells. By blocking this process, Oseltamivir limits the spread of the virus within the respiratory tract, helping the body’s immune system control and clear the infection more effectively.

Who Should Use Fluvir (Oseltamivir)

Fluvir is suitable for adults and children who have influenza or have been recently exposed to the virus. It is especially recommended for individuals at high risk of flu complications, such as the elderly, immunocompromised patients, and those with chronic heart or lung diseases. Patients with severe kidney impairment may require dose adjustments. Always consult your doctor before starting antiviral therapy.
