Failure to respond to FDA warning letters successfully can result in more than just product development and abandonment. The FDA can file warning letters with fines, property confiscation, court orders, and even law enforcement (in cases of public safety concerns or deliberate / reckless behavior).
Additionally, the Federal Trade Commission (FTC) and state regulators can waive FDA warning letters and initiate enforcement of their own.
