The 2009 pandemic H1N1 influenza virus continues to be the dominant influenza virus in circulation in the U.S. The benefit of antiviral treatment is greatest when it is initiated as early as possible in the clinical course. (Source: CDC Swine Flu Updates)
This podcast discusses the use of antiviral drugs for the treatment and prevention of influenza, including 2009 H1N1, during the 2009-2010 influenza season. (Source: CDC Swine Flu Updates)
Grapefruit seed extract or GSE is also known as citrus seed extract. Grapefruit seed extract is a liquid derived from the seeds, pulp, and white membranes of grapefruit.

Four different influenza antiviral medications (amantadine, rimantadine, oseltamivir, and zanamivir) are approved by the U.S. Food and Drug Administration (FDA) for the treatment and/or prevention of influenza. All four usually work against influenza A viruses. However, the drugs may not always work, because influenza virus strains can become resistant to one or more of these medications. For example, the influenza A (H5N1) viruses identified in human in Asia in 2004 and 2005 have been resistant to amantadine and rimantadine. Monitoring of avian viruses for resistance to influenza antiviral medications continues.
Protocol for Antiviral Susceptibility Testing by Pyrosequencing, Sequencing Primers and Protocol, and CDC Protocol of Realtime RTPCR for Swine Influenza A(H1N1)
The U.S. Food and Drug Administration, in response to requests from the U.S. Centers for Disease Control and Prevention, has issued Emergency Use Authorizations (EUAs) to make available to public health and medical personnel important diagnostic and therapeutic tools to identify and respond to the swine flu virus under certain circumstances. The agency issued these EUAs for the use of certain Relenza and Tamiflu antiviral products, and for the rRT-PCR Swine Flu Panel diagnostic test.
Provides interim guidance on the use of antiviral agents for treatment and chemoprophylaxis of swine influenza A (H1N1) virus infection. This includes patients with confirmed, probable or suspected swine influenza A (H1N1) virus infection and their close contacts.
CDC recommends the use of oseltamivir or zanamivir for the treatment or prevention of infection with swine influenza viruses. These medications must be prescribed by a health care professional.
