Emergency Use Authorization
The Emergency Use Authorization (EUA) authority allows FDA to help strengthen the nation’s public health protections against CBRN threats by facilitating the availability and use of MCMs needed during public health emergencies.
Under section 564 of the Federal Food, Drug, and Cosmetic Act (FD&C Act), the FDA Commissioner may allow unapproved medical products or unapproved uses of approved medical products to be used in an emergency to diagnose, treat, or prevent serious or life-threatening diseases or conditions caused by CBRN threat agents when there are no adequate, approved, and available alternatives.
Section 564 of the FD&C Act was amended by the Project Bioshield Act of 2004 and the Pandemic and All-Hazards Preparedness Reauthorization Act of 2013 (PAHPRA), which was enacted in March 2013
Guidance
In January 2017, FDA finalized the guidance: Emergency Use Authorization of Medical Products and Related Authorities. For more information, please see the January 13, 2017 Federal Register notice.
Questions & Answers
In January 2014, FDA issued a question and answer document (PDF, 762K) to respond to questions raised by public health stakeholders about PAHPRA’s amendments to the EUA authority and establishment of new authorities related to the emergency use of MCMs during CBRN emergencies.
