Amantadine (Symmetrel, generic) and Rimantadine (Flumadine, generic) - High Levels of Resistance By Influenza A H3N2 Viruses
January 19, 2006
The World Health Organization (WHO) and National Respiratory and Enteric Virus Surveillance System (NREVSS) have noted increased resistance of Influenza A H3N2 viruses to amantadine (Symmetrel, generic) and rimantadine (Flumadine, generic). For the remainder of the 2005 – 2006 influenza season, the Centers for Disease Control and Prevention (CDC) now recommends using only oseltamivir (Tamiflu) or zanamivir (Relenza) for the treatment of influenza, and using oseltamivir for chemoprophylaxis. Amantadine or rimantadine are not recommended for treatment or chemoprophylaxis at this time.
