Why do I need to take Tamiflu?

Tamiflu does not kill the virus. If that was the case, it would be similar to Antibiotics. Tamiflu reduces the virus from spreading to potential healthy host cells in the body. A host cell is a cell (any cell in the body that H1N1 concentrates on in this case) that is the home of the reproduction of the virus. Tamiflu basically freezes the virus from attacking the host cell. Therefore it usually dies off. It's not 100% effective, the virus may get by sometimes. Anyway, the doctor perscribed it to you so that you have less of a chance in showing symptoms, and becoming infected. So its a good idea to take!
