Tamiflu is a means of preventing and treating influenza A and B. With the drug you can reduce the course of disease by up to 2 days to make you feel better again soon. The product is manufactured and marketed by the pharmaceutical company Roche.
Because the flu is caused by a virus, you can not use penicillin or other antibacterial medicines to fight the disease. Most people therefore need patience and wait for the disease to go over by itself. But with Tamiflu, you can shorten your course of illness so you can recover faster.

How does Tamiflu work?
The medicine is an antiviral treatment containing the active substance Oseltamivir. The drug inhibits the spread of the influenza virus by preventing the virus from entering new cells into the respiratory tract. In addition, the treatment stops the development of new viruses.
To spread, the virus needs an enzyme called neuraminidase. This enzyme helps the virus into the body, but the active substance oseltamivir binds to the enzyme, thus preventing further viruses in the body.
The treatment does not kill the existing virus, but by inhibiting the development of the virus, the body gets the job of stopping the virus attack. The virus, therefore, remains local and it is much easier for the body’s immune system to control the virus infection.
This will cause you to get better 1-2 days earlier than without treatment. In order to achieve the best effect of treatment, it is important to take it as quickly as possible during the course of the disease.
The treatment can also be used as a preventive treatment in special cases. This applies to epidemics or pandemics, where there are large sections of the population affected by the infection. It can also be used as a preventive treatment for people at particular risk of developing complications in relation to viral infection.
How to use the treatment
The medicine comes as a tablet form and can be taken at different times during the course of the disease or on suspected infection.

Who is suitable for the treatment?
Most people can use the treatment to prevent or treat the flu. If you have kidney problems, it is not a recommended treatment. In addition, pregnant women and breastfeeding women should only use the treatment under special circumstances, for example if there is a pandemic with influenza A.
The treatment is often used for people who are particularly sensitive to flu or who are at greater risk of developing complications if they are infected with the virus. However, it is used by most to shorten the course of illness.
Tamiflu or influenza vaccination?
Tamiflu treatment cannot replace a flu vaccine. When you receive a vaccination, it will protect you from the fact that the disease occurs at all. Tamiflu can only make the disease progressively shorter or prevent the disease to a certain level in special cases. It is not recommended to take medication unnecessarily, and therefore Tamiflu should only be used in special cases as a preventive treatment.
If you have a weak immune system or if there is a reason to suspect that an influenza virus may develop into serious complications, then a flu vaccine is better protected than Tamiflu.
