What medicine can prevent the A H1N1 virus?

Tamiflu (oseltamivir) and Relenza (zanamivir) are antiviral medications that can be used to prevent and treat the A H1N1 virus, commonly known as the swine flu. These medications work by blocking the action of the virus, preventing it from spreading and causing infection. However, it's important to note that these medications are only effective if taken as prescribed by a healthcare provider and should not be used as a substitute for preventive measures such as vaccination, hygiene practices, and social distancing.
