What Oseltamivir Lupin is used for
Oseltamivir Lupin is an antiviral medicine containing the active ingredient oseltamivir.
Oseltamivir Lupin is used for the treatment and prevention of influenza (an infection caused by the influenza virus). It has no effect on the common cold or other respiratory virus infections.
Oseltamivir Lupin belongs to a group of medicines called neuraminidase inhibitors. These medicines attack the influenza virus and prevent it from spreading inside your body.
Oseltamivir Lupin is absorbed to the key sites of influenza infection and treats the cause.
Taking Oseltamivir Lupin means you feel better faster.
You will also be less likely to develop complications of influenza, such as bronchitis, pneumonia and sinusitis.
Ask your doctor if you have any questions about why Oseltamivir Lupin has been prescribed for you.
Oseltamivir Lupin is not addictive.
This medicine is available only with a doctor’s prescription.
Ask your doctor about having the influenza vaccination. Vaccination every year is the best way to prevent influenza.

- add a suitable, small amount (1 teaspoon maximum) of sweetened food product such as regular or sugar-free chocolate syrup, honey (only for children two years or older), light brown or table sugar dissolved in water, dessert toppings, sweetened condensed milk, apple sauce or yogurt to mask the bitter taste of the medicine
- stir the mixture well and give the entire contents of the bowl to the patient. The mixture must be swallowed immediately after its preparation. If there is some mixture left inside the bowl, rinse the bowl with a small amount of water and have the patient drink this remaining mixture.

- hold one Oseltamivir Lupin 75 mg capsule over a small bowl, carefully pull the capsule open and pour the powder into the bowl
- add 5 mL water to the powder using a syringe with markings (called a “graduated syringe”) to show how much fluid has been drawn up. Stir for about two minutes
