Final answer:
Both the retail pharmacy and the central fill pharmacy must maintain prescription records for at least two years as mandated by the FDA and DEA regulations.
Step-by-step explanation:
When a pharmacy is using a central fill pharmacy, both the retail pharmacy (that received the original prescription) and the central fill pharmacy (that actually fills the prescription) are required to maintain prescription records. According to regulations set forth by the Food and Drug Administration (FDA) and the Drug Enforcement Administration (DEA), these records must typically be kept for a minimum of two years after the date of the last fill. It is essential for both entities to maintain accurate records to ensure the safety and efficacy of medication dispensing, and also for accountability and tracing in case of audits or investigations. Pharmacists, as part of their comprehensive career focus, must be familiar with the legal requirements related to the dispensation and record-keeping of prescription drugs to ensure compliance with these regulatory standards.
