Product introduction
Antiflu Syrup contains oseltamivir, an antiviral medicine used to treat and help prevent influenza (flu) caused by influenza A and B viruses. It is commonly prescribed for children and adults who develop flu symptoms within the first day or two of illness, when it works best. The liquid formulation makes it convenient for children or anyone who has difficulty swallowing tablets. It is available only with a valid doctor's prescription.
Storage: Store below 30°C
Uses of Antiflu Syrup
- Treatment of influenza (flu)
- Prevention of influenza after exposure to an infected person
- Relief of flu-related fever and body aches
- Shortens duration of flu symptoms when started early
Benefits of Antiflu Syrup
When started early in the course of illness, oseltamivir can shorten the duration of flu symptoms and reduce how severe they feel. It may also lower the risk of flu-related complications, such as chest infections, in people who are more vulnerable to them. Doctors sometimes prescribe it as a short preventive course for people who have been in close contact with someone diagnosed with flu.
Side effects of Antiflu Syrup
Most side effects do not require medical attention and go away as your body adjusts. Consult your doctor if they persist.
- Nausea
- Vomiting
- Abdominal pain
- Diarrhea
- Headache
- Body pain
How to use Antiflu Syrup
Antiflu Syrup should be taken exactly as advised by the doctor, usually with food to reduce stomach upset. Shake the bottle well and measure each dose carefully with the measuring cup or oral syringe provided. Complete the full course even if symptoms improve after a few days, since stopping early can allow the virus to persist.
How Antiflu Syrup works
Oseltamivir works by blocking an enzyme called neuraminidase, which the influenza virus needs to spread from one infected cell to another inside the body. By inhibiting this enzyme, the medicine slows the spread of the virus and gives the immune system more time to clear the infection. This is why it is most effective when started soon after symptoms begin.

Safety advice
The interaction between alcohol and oseltamivir has not been well studied, so it is best to avoid alcohol while unwell and on treatment.
Oseltamivir is generally considered acceptable during pregnancy when a doctor judges the benefits outweigh the risks, particularly during flu outbreaks.
Small amounts of the medicine may pass into breast milk, so a doctor should be consulted before use while breastfeeding.
The medicine is not known to cause dizziness or drowsiness that would affect driving, though you should judge based on how you feel while unwell.
People with significant kidney impairment may need a lower dose, so kidney function should be assessed before starting treatment.
No dose adjustment is generally required for people with liver disease, but any liver condition should still be discussed with the doctor.
