To whom should potential counterfeit medications be reported?

The correct choice is reporting potential counterfeit medications to the FDA, as this agency is primarily responsible for regulating drugs and ensuring their safety and efficacy in the United States. The FDA plays a crucial role in monitoring and combating counterfeit medications, which can pose serious health risks to patients. They have established protocols for handling reports of counterfeit products and take action to investigate and remove dangerous medications from the market.

The Oregon Board of Pharmacy focuses on the regulation of pharmacy practice within the state, although it may be informed or involved after the FDA's initial assessment. The Federal Bureau of Investigation (FBI) does handle certain types of pharmaceutical fraud but is not the primary agency for reporting counterfeit drugs. Lastly, the Drug Enforcement Administration (DEA) is more focused on controlled substances and narcotics rather than counterfeit medications; therefore, it would not be the appropriate authority for reporting these concerns.
