For how long must C-II invoices be retained according to regulations?

C-II invoices must be retained for a period of 2 years according to regulations set by the Drug Enforcement Administration (DEA). This requirement is crucial for compliance with federal regulations that govern the handling of controlled substances. Retaining these invoices for the appropriate duration ensures that pharmacies maintain accurate records for auditing and inventory purposes, helping prevent drug diversion and misuse.

Proper record-keeping for the prescribed length of time allows for effective tracking of the controlled substances from supplier to pharmacy and ultimately to the patient. It is essential for pharmacy technicians and related professionals to understand these regulations, as non-compliance can result in legal consequences and jeopardize the integrity of the pharmacy’s operations.
