FDA-approved antiviral agents represent an important class that has attracted attention in recent years to combat current and future threats of viral pandemics.

Herein, we summarized the fluorinated FDA-approved antiviral agents, dealing with biological aspects, mechanisms of action, and synthetic pathways.
