How can a pharmacy clearly mark a prescribed medication as 'forged'?

A pharmacy can mark a prescribed medication as 'forged' by documenting properly and storing it securely, as this method provides a clear and legal record of the incident. Accurate documentation is crucial in a situation involving a suspected forged prescription because it not only creates a trail for future reference, but it also serves to protect the pharmacy's interests in case of legal scrutiny. This documentation should include details such as the prescription itself, the date, any communications regarding the prescription, and actions taken by the pharmacy staff. Secure storage ensures that the medication cannot be dispensed or misused, thus maintaining safety and adhering to best practice standards.

In addition to this, while notifying law enforcement or returning the medication might be reasonable actions for ensuring safety or compliance with the law, they don't necessarily provide the same level of clarity and security regarding the documentation of the incident itself. Destroying the medication on-site could eliminate any potential evidence needed for an investigation, making proper documentation and secure storage the most prudent approach in this scenario.
