Tamiflu® Singapore
Last updated: Sep 30, 2026
What Is Tamiflu?
Tamiflu is the brand name for oseltamivir, an antiviral medicine used to treat and prevent influenza (flu). Taken as a capsule or an oral suspension, it works by reducing how severe the symptoms are and how long they last, helping you recover sooner and return to your daily activities.
Influenza Symptoms
Symptoms of influenza can appear within 1 to 4 days after exposure to the influenza virus and can range from mild to severe:
- Fever or chills
- Cough
- Sore throat
- Runny or stuffy nose
- Headaches
- Fatigue
- Muscle or body aches
- Some individuals, especially children, may also experience vomiting and diarrhoea
How Does Tamiflu Work?
Tamiflu works by inhibiting the activity of
neuraminidase, an enzyme present on the
surface of the influenza virus. This action prevents the virus from spreading to healthy
cells, helping to slow down the progression and reduce the severity of the flu.
Tamiflu is most effective in shortening the duration of flu symptoms by approximately 1 day when taken
within 48 hours of noticing symptoms.
It is typically prescribed for 5 days and is best
taken with food to minimise possible side effects.
Tamiflu Side Effects
While Tamiflu is generally well-tolerated, some individuals may experience side effects that can include:
- Nausea
- Vomiting
- Diarrhoea
- Stomach pain
- Headache
- Dizziness
In rare cases, individuals may experience more severe side effects such as allergic reactions or neuropsychiatric events, including confusion and abnormal behaviour. It is important to consult a doctor promptly if any severe or unusual symptoms occur.
