When must a successor for a PIC be named?

A successor for a Pharmacist in Charge (PIC) must be named immediately after the current PIC resigns to ensure there is no lapse in management and oversight at the pharmacy. The role of the PIC is critical as they are responsible for maintaining compliance with all pharmacy regulations and ensuring patient safety. Prompt appointment of a new PIC helps maintain continuity in operations and leadership, which are essential for both regulatory compliance and the smooth functioning of the pharmacy.

While other options present varying degrees of timelines or conditions regarding the appointment of a successor, they do not adequately address the immediacy required in this scenario. Timely action upon the resignation of a PIC avoids potential disruptions in pharmacy operations and helps mitigate any legal or regulatory risks associated with the oversight of pharmacy practices.
