In October 2009, the U.S. Food and Drug Administration (FDA) issued an emergency use authorization (EUA) for the use of peramivir based on safety data from phase I, phase II, and limited phase III trial data. The emergency use authorization for peramivir expired in June 2010. On 19 December 2014, the FDA approved peramivir to treat influenza infection in adults.
