Introduction to Tamiflu (Oseltamivir) 75mg
Flutavir (Oseltamivir) 75mg is a prescription antiviral medicine used for the treatment and prevention of influenza (flu) infections caused by influenza A and B viruses. It helps reduce the severity and duration of flu symptoms when taken early.
This medicine belongs to a class of drugs known as antiviral agents that work by blocking the spread of the virus inside the body.
Flutavir (Oseltamivir) 75mg is classified under Prescription Medicines, Antiviral Drugs, Infectious Disease Medicines, and Oral Flu Therapies. It contains Oseltamivir, which inhibits viral replication and helps control infection.
Generic versions such as Flutavir 75mg provide similar therapeutic effects as the original brand when prescribed by a qualified healthcare professional.
What Is Tamiflu (Oseltamivir)?
Tamiflu is the original brand name for Oseltamivir, an oral antiviral medication widely used to treat influenza infections.
Oseltamivir belongs to a group of medicines called neuraminidase inhibitors. These drugs prevent the influenza virus from spreading to healthy cells in the respiratory tract.
Generic brands such as Flutavir 75mg contain the same active ingredient and may be used depending on physician recommendation and availability.
Drug Class and Mechanism of Action
Oseltamivir is classified as a neuraminidase inhibitor with strong antiviral properties.
How Oseltamivir Works
It works in several ways:
- Blocks the neuraminidase enzyme of influenza viruses
- Prevents the release of new virus particles
- Limits the spread of infection in the respiratory tract
- Helps the immune system clear the virus more effectively
Through these actions, Oseltamivir helps reduce flu symptoms and recovery time.
How Tamiflu Works in the Body
Influenza viruses multiply rapidly in the body. Oseltamivir slows this process and helps control the infection.
Key Actions of Oseltamivir
- Reduces viral replication
- Shortens duration of flu symptoms

- Helps prevent complications in high-risk patients
Generic versions such as Flutavir provide the same antiviral effect when used properly.
