Benefits Of Antiviral Drugs
Benefits of Antiviral Drugs
Treatment: If you get sick, antiviral drugs can make your illness milder and make you feel better faster. They may also prevent serious influenza complications. Influenza antiviral drugs work best when started soon after illness onset (within two 2 days), but treatment with antiviral drugs should still be considered after 48 hours of symptom onset, particularly for hospitalized patients or people at high risk for influenza-related complications.
Prevention: Influenza antiviral drugs also can be used to prevent influenza when they are given to a person who is not ill, but who has been or may be near a person with swine influenza. When used to prevent the flu, antiviral drugs are about 70% to 90% effective. When used for prevention, the number of days that they should be used will vary depending on a person's particular situation.
Recommendation
we recommend the use of oseltamivir or zanamivir for the treatment and/or prevention of infection with swine influenza viruses.
* Oseltamivir (brand name Tamiflu) is approved to both treat and prevent influenza A and B virus infection in people one year of age and older.
* Zanamivir (brand name Relenza ) is approved to treat influenza A and B virus infection in people 7 years and older and to prevent influenza A and B virus infection in people 5 years and older.
Recommendations for using antiviral drugs for treatment or prevention of swine influenza will change as we learn more about this new virus.
Clinicians should consider treating any person with confirmed or suspected swine influenza with an antiviral drug.
