How should Tamiflu be used?
To provide any benefit, Tamiflu must be started within two days of the onset of symptoms, or exposure to the flu. If you have the flu, continue taking it twice daily for 5 days, even if you start to feel better. To prevent the flu, take it once a day for at least 7 days. Protection lasts as long as you take the drug. The capsules have an expiry date of 2010 and can be used up to that time.
How does Tamiflu work?
This medicine contains the active ingredient oseltamivir phosphate, which is a type of medicine called a neuraminidase inhibitor. It is used to treat and prevent infection with the influenza virus (flu).
Flu is caused by a highly contagious virus which affects the respiratory system. The virus is passed from one person to another by coughing and sneezing. When the virus enters the body it invades cells, where it replicates to form lots of new virus particles.
These new copies of the virus are then released from the cells and move on to infect adjoining cells, where the process is repeated. After a couple of days a sufficient number of cells have been infected so that the patient feels flu symptoms such as headache, fever and general aches and pains, which continue for about a week until the body's immune system kills the virus.
In order to leave one cell and infect another, the flu virus uses a chemical helper that is found on its surface. This substance is an enzyme called neuraminidase. Tamiflu works by binding to the enzyme and stopping the release. This prevents the flu virus from spreading and infecting other cells.
Tamiflu therefore confines the infection to a smaller area. This makes the symptoms of the infection less severe and also makes it is easier for the body's immune system to kill the virus.
Tamiflu is only effective against the influenza virus. It will not work against illnesses that are caused by other agents
